Ford Key Replacement in Cerritos, CA

How Ford keys and immobilizers work

Ford's immobilizer is PATS, the Passive Anti-Theft System, sold under the SecuriLock name. A transponder sealed in the key head, or built into the fob on push-button models, answers a coded challenge from a coil around the ignition or from antennas in the cabin, and the engine won't run until the powertrain computer accepts the answer. Across 2000-2026 the chip changed in clear steps. Pickups, big SUVs and the Crown Victoria used a fixed-code Texas 4C chip into the early 2000s, and the Excursion kept it through 2005. The first Escape and early Focus used a Texas 4D60. Between 2000 and 2004 most of the lineup moved to the encrypted Texas 4D63, with 80-bit versions becoming the norm around 2011, while most catalogs list the E-Series van with chip keys only from 2008. NXP Hitag Pro arrived with the 2013 Fusion, reached the F-150 for 2015 and now covers nearly the whole lineup. Remote-head keys appeared in the mid-2000s, Intelligent Access push-button fobs around 2010, and long-range 902 MHz fobs came with remote start. Recent models use 434 MHz fobs, and the Mustang Mach-E and F-150 Lightning added Phone As A Key.

Ford key programming

Nearly all Ford key programming runs through the OBD-II port. On turn-key Fords from roughly 2000 to 2014, our programmer requests PATS security access, often a timed wait of about ten minutes, and then adds a key or erases and rebuilds the key list. If you already have two working keys, many of these vehicles also accept Ford's owner procedure, where each good key is switched on in turn, followed by the newly cut key. A fixed-code 4C key can simply be cloned. Most separate remotes from that era pair when the ignition is cycled eight times in quick succession, while integrated remote-head keys usually learn their buttons along with the chip. Hitag Pro flip keys and every push-button fob are registered with a programmer. On many 2015-and-later models an active alarm means an emulator or bypass cable for all-keys-lost work, and some 2020-and-later models add an online authorization step. We check your ID and registration or title before we start.

All Ford keys lost

When every key to a Ford is gone, older models are usually a single visit. We cut a working key from the factory key code or by decoding a door lock, then erase the missing keys from PATS and program new ones, so a lost key that turns up later won't start the vehicle. Ford's procedure expects at least two keys after an erase, so plan on two. Push-button Fords get new fobs plus freshly cut emergency blades through the same port. On push-button Fords from about 2015 on, an active alarm often means an emulator or bypass cable, and on many 2020-and-later models, including the current F-150, Super Duty, Bronco and Explorer, all-keys-lost can also call for an online security step or, on some builds, the dealer. We check your VIN against current tool coverage before quoting, and we ask for ID and proof of ownership first.

Ford models we cover

• Bronco (2021–2026). Ford brought the Bronco name back for 2021 as a body-on-frame off-roader with two- and four-door bodies, removable doors and roof panels, and trims running from Base up to the wide-body Raptor. Its keys come from Ford's current Hitag Pro hardware: smart fobs with push-button start on most trucks, plus a flip key on some early entry-level models. For 2025, Ford moved the Bronco to 434 MHz fobs, so a fob from an earlier truck won't program to a newer one. The smaller Bronco Sport is a different vehicle and is listed separately.
• Bronco Sport (2021–2026). The Bronco Sport is a compact crossover that arrived for 2021, built on the same platform as the Escape and Maverick and styled to echo the bigger Bronco. Entry-level trucks may be built with a turned key, while Big Bend and higher trims use Intelligent Access fobs with push-button start. Bronco Sports come with Ford's door-mounted SecuriCode keypad, which is handy when a fob gets locked inside. Fob hardware has changed during the run, so we match your existing fob's FCC ID or your VIN before ordering a replacement.
• C-Max (2013–2018). The C-Max was a tall five-door hatchback sold in the US from 2013 to 2018, only as a gasoline-electric hybrid or as the plug-in C-Max Energi. It shares much of its hardware with the Focus and Escape of the same years, including the side-milled HU101 key blade. SE models start with a remote-head key in a conventional ignition, while SEL models, the Titanium models that replaced them for 2017, and the Energi use an Intelligent Access fob and a start button. Knowing the trim tells us which key to bring.
• Contour (2000–2000). The Contour was Ford's compact front-drive sedan from the 1995 through 2000 model years, built in Kansas City, Missouri, and in Mexico. Only the 2000 model year falls in our range, and it was also the last year for the SVT Contour. Its key is the less common H73-style transponder blank shared with the Mercury Mystique and Cougar, rather than the more familiar H72 of the Mustang and Crown Victoria, so we identify the blank before we cut anything. Spare keys for a car this age are usually straightforward once we confirm the chip.
• Crown Victoria (2000–2011). Ford's full-size, rear-drive sedan was the standard police car and taxi in much of America for years, and plenty of retired Police Interceptors are now in private hands. The US Crown Victoria was built through the 2011 model year, and from 2008 it was sold mainly to fleet buyers. Every one from 2000 on uses a SecuriLock chip key: a fixed-code 4C key through 2002 and an encrypted 4D63 key after the 2003 update. Keyless entry, where fitted, is a separate remote, and one key works the doors, trunk and ignition.
• E-Series / Econoline (2000–2026). The E-Series, long sold as the Econoline, was Ford's full-size van through the 2014 model year, when the Transit took over the van role. The cutaway and stripped-chassis versions carried on and still underpin many box trucks, shuttle buses, ambulances and motorhomes. Key systems vary more than on most Fords: older vans often have no PATS chip at all, the catalogs we checked list chip keys from 2008, and the newest chassis are best confirmed by VIN before we cut anything.
• E-Transit (2022–2026). The E-Transit is the battery-electric version of the full-size Transit, built in Kansas City and sold as a van, cutaway and chassis cab since the 2022 model year. Like other electric vehicles, it has no key in a conventional ignition: you press the brake and the start button with a smart fob present. Because the electronics are new and share Ford's current Transit architecture, key work depends on current programmer coverage, and the catalogs we checked do not list the E-Transit by name. We confirm the fob from your VIN before ordering anything.
• EcoSport (2018–2022). The EcoSport was Ford's smallest crossover in the US, sold for the 2018 through 2022 model years with a three-cylinder turbo engine or, on all-wheel-drive models, a 2.0-liter four. Its key hardware comes from Ford's Hitag Pro generation: lower trims start with a three-button flip key, and better-equipped models use a smart fob with push-button start. Both use the side-milled HU101 blade. The parts are shared with other Fords of the period, so replacements are easy to source.
• Edge (2007–2024). The Edge was Ford's two-row midsize crossover from 2007 through 2024, built in Oakville, Ontario. Its keys track Ford's technology almost year by year: 40-bit remote-head keys at launch, 80-bit remote-head keys and an optional Intelligent Access fob from 2011, then push-button start with Hitag Pro smart fobs from the 2015 redesign onward. Sport and ST models use the same key systems as other Edges of their year, though some of their fobs carry their own part numbers. Because the hardware changed so often, the model year tells us most of what the job involves.
• Escape (2001–2026). The Escape has been Ford's compact crossover since the 2001 model year, and the 2005 Escape Hybrid was the first hybrid SUV sold in the US. Across four generations, its keys went from a 4D60 chip key with a separate remote, to 4D63 chip and remote-head keys, to side-milled HU101 keys and an Intelligent Access fob in 2013, and on to Hitag Pro flip keys and fobs from 2020. Ford has said the Escape ends after the 2026 model year. The Mazda Tribute and Mercury Mariner are close relatives of the early Escape.
• Escort (2000–2002). The Escort sedan was Ford's entry-level compact, and its last design ran from the 1997 through 2002 model years. Our range covers 2000 through 2002. Ford sold the 2001 and 2002 sedans to fleet buyers only, and many later reached private owners as used cars. Power came from a 2.0-liter single-cam four. The two-door coupe from the same family is listed separately as the ZX2.
• Excursion (2000–2005). The Excursion was Ford's largest SUV, sold for the 2000 through 2005 model years on the Super Duty truck chassis with gas V8 and V10 engines or a Power Stroke diesel. Every year uses the same key setup: a fixed-code Texas 4C SecuriLock chip key that works the doors and ignition, with keyless entry on a separate remote. That makes a lost-key call on an Excursion one of the more straightforward truck jobs, and a spare can be cloned from a working key without touching the truck's computer.
• Expedition (2000–2026). The Expedition is Ford's full-size, three-row SUV, built on F-150 underpinnings and paired with the Lincoln Navigator. Its key history spans nearly every Ford system: fixed-code 4C keys through 2002, 4D63 keys from the 2003 redesign, remote-head keys and then Intelligent Access fobs, Hitag Pro fobs with the 2018 redesign, 434 MHz fobs from 2023, and an all-new truck for 2025. The long-wheelbase EL and Max versions use the same keys as the standard truck of their year.
• Explorer (2000–2026). The Explorer is Ford's best-known midsize SUV, and within 2000-2026 it has been body-on-frame, then a unibody crossover from 2011, then rear-drive based again from 2020. Its keys followed along: 4C chip keys on the last second-generation trucks, 4D63 chip keys and separate remotes through 2010, remote-head keys and Intelligent Access fobs from 2011, Hitag Pro flip keys and fobs from 2016, and push-button fobs on most trucks since 2020. The pickup version is listed separately as the Explorer Sport Trac, and the three-door Explorer Sport of 2000-2003 follows the key system of its model year.
• Explorer Sport Trac (2001–2010). The Explorer Sport Trac paired an Explorer cab with a short pickup bed. The first version ran from 2001 to 2005 on the older Explorer body, and a redesigned one returned for 2007 through 2010, based on the fourth-generation Explorer. Both use Ford's SecuriLock chip key in a turned ignition, with keyless entry on a separate remote, so they are simple trucks to key from scratch. The 2001 trucks sit right at Ford's changeover from the 4C chip, so we check the chip in your existing key whenever one is available.
• F-150 (2000–2026). Ford's F-Series has been America's best-selling pickup line for decades, and the F-150 covers more Ford key systems than any other model. From 2000 to 2026 it went from fixed-code 4C chip keys, to 4D63 chip keys with separate remotes, to remote-head keys in 2011, Hitag Pro flip keys and smart fobs on the aluminum-body 2015 truck, an inner-milled HU198 blade from 2021, and 434 MHz fobs around 2024. Raptor and other special trims use the same key families as the trucks of their year.
• F-150 Lightning (2000–2025). Two very different trucks have worn the Lightning name since 2000. The SVT Lightning of 2000-2004 was a supercharged, street-focused regular-cab F-150 with the same SecuriLock chip key as the standard truck. The battery-electric F-150 Lightning arrived for 2022 with Hitag Pro smart fobs and Ford's Phone As A Key on equipped trucks, and Ford announced the end of its production in December 2025, making 2025 its final model year. The two are keyed in completely different ways, so tell us which one you have when you call.
• Fiesta (2011–2019). The Fiesta was Ford's subcompact sedan and hatchback in the US from the 2011 through 2019 model years, built in Mexico, with the turbocharged Fiesta ST hatchback added for 2014. It uses Ford's European-style hardware: a side-milled HU101 blade, remote-head keys on most cars, and an Intelligent Access fob with push-button start on higher trims. Because two different remote-head key families were used over the years, the FCC ID on your current key tells us which one to bring.
• Five Hundred (2005–2007). Ford's full-size sedan of 2005-2007 rode on a Volvo-derived platform, offered all-wheel drive, and gave buyers a tall seating position and a very large trunk. It was renamed Taurus for 2008, so later cars of the same design are listed under that name. Every Five Hundred uses a SecuriLock transponder key on a turn-key ignition, with keyless entry handled by a separate four-button remote. That makes it one of the simpler cars of its era for a mobile locksmith to key from scratch.
• Flex (2009–2019). The boxy three-row Flex ran from 2009 through 2019 on the same D4 platform as the Taurus and Lincoln MKT, with an EcoBoost V6 optional from 2010. Early Flexes start with a remote-head key, where the lock buttons are molded into the key head. The 2013 refresh added Intelligent Access with push-button start on upper trims, so later years can arrive with either a remote-head key or a smart fob. Knowing which one is in your pocket tells us what to bring.
• Focus (2000–2018). Ford's compact arrived for 2000 as a sedan, hatchback and wagon and stayed in US showrooms through the 2018 model year. Its key hardware changed more than almost any other Ford: a 4D60 chip key early on, then 4D63 chip keys with a separate remote or an integrated remote-head key, and a third generation that mixed high-security remote-head keys with several different smart fobs. The SVT, ST and RS performance models follow the key rules of their generation, with a few fob differences noted below.
• Freestar (2004–2007). The Freestar replaced the Windstar for 2004 and sold through 2007 alongside its Mercury Monterey twin. It's a conventional front-drive minivan with a turn-key ignition, a SecuriLock transponder key, and a separate remote that on many vans also works the power sliding doors. Because the key system stayed the same for all four model years, a Freestar is usually a straightforward key job, though the remote has to match your van's door options.
• Freestyle (2005–2007). The Freestyle was Ford's 2005-2007 three-row crossover wagon, built on the same Volvo-derived platform as the Five Hundred sedan and available with all-wheel drive. For 2008 it was updated and renamed Taurus X, which is listed separately. Freestyle keys are simple by modern standards: a chip key with a turn-key ignition and a separate remote, with no smart key or push-button start offered. Most calls for this car are for a spare key or for replacing the only key after it goes missing.
• Fusion (2006–2020). Ford's midsize sedan ran from 2006 through 2020, including Hybrid and, later, Energi plug-in versions. The first generation brought remote-head keys to many Ford buyers, and the 2013 redesign added a side-milled high-security flip key and an optional smart fob with push-button start. The 2017 refresh moved to Ford's newer smart fob design. Because key hardware changed at 2011, 2013 and 2017, the year on your registration narrows down the right key quickly.
• GT (2005–2022). Ford's mid-engine supercar exists in two very different forms. The 2005-2006 GT, a modern take on the GT40, uses ordinary Ford key hardware of its day, including a fixed-code 4C transponder. The carbon-fiber 2017-2022 GT was built in small numbers by Multimatic, sold through an application process, and uses a modern smart fob. The older car is a standard locksmith job; keys for the newer car are best sourced through a Ford dealer approved to handle it.
• Maverick (2022–2026). The Maverick compact pickup launched for 2022 with a hybrid as its standard powertrain and an optional 2.0-liter EcoBoost, built on the same platform as the Bronco Sport and Escape. Keys follow trim level: Lariat trucks have a smart fob and push-button start, lower trims may have a turned ignition and a flip key, and the 2025 refresh brought a new 434 MHz smart fob. These are recent Ford systems, so a spare is usually straightforward, but an all-keys-lost job depends on current tool coverage for your VIN.
• Mustang (2000–2026). Ford's pony car has been sold in every year this guide covers, and its keys trace Ford's whole immobilizer history: a fixed-code 4C chip key through 2004, 4D63 keys with a separate remote on the 2005 redesign, remote-head keys from 2010, standard push-button start from 2015, and a new 434 MHz fob on the 2024 S650. Shelby, Bullitt, Mach 1, Boss and Dark Horse models use the key hardware of their generation.
• Mustang Mach-E (2021–2026). The Mach-E is Ford's electric crossover, sold since the 2021 model year in Select, Premium, California Route 1, GT and later Rally trims. It is a very different key experience from the Mustang coupe: Phone As A Key is standard, a keypad on the driver's B-pillar can open the car, and the doors open with electronic buttons instead of conventional handles. Smart fobs are supplied as well. Because so much runs through software, Mach-E key work is more limited than on older Fords.
• Ranger (2000–2026). Ford's smaller pickup covers two eras here. The long-running US Ranger was sold through the 2011 model year with a chip key and separate remote. After a seven-year break, a midsize Ranger built on the global T6 platform returned for 2019 with flip keys or smart fobs, and a fully redesigned Ranger, including the Raptor, followed for 2024. Mazda's B-Series pickup shared the older truck's key system, so those keys are often interchangeable.
• Super Duty (F-250/F-350) (2000–2026). Ford's Super Duty pickups, the F-250 and F-350 covered here, split from the F-150 for the 1999 model year with their own cabs, frames and key hardware. Generations ran 1999-2007, 2008-2010, 2011-2016, 2017-2022 and 2023 on. Keys moved from fixed-code 4C chip keys, to 4D63 chip keys and then remote-head keys, to Hitag Pro flip keys and smart fobs in 2017, and to 434 MHz fobs with an HU198 blade in 2023. Gas and Power Stroke diesel trucks of the same year use the same keys, and catalogs list the F-450 and F-550 with the F-250 and F-350 keys from 2011 on.
• Taurus (2000–2019). The Taurus spans three designs in this guide. The 2000-2007 sedan and wagon carried Ford's family-car role, with the 2007 model sold only to fleets. For 2008-2009 the Five Hundred was renamed Taurus, and the 2010-2019 sedan, including the turbocharged SHO and the Police Interceptor built from it, brought remote-head keys and an optional smart key. Every Taurus of these years has a chip key or fob, and all are well covered by locksmith programming equipment.
• Taurus X (2008–2009). The Taurus X was the 2008-2009 update of the Freestyle crossover, with a new nose, a 3.5-liter V6 and a new name, and Ford dropped it after the 2009 model year. It seats seven and offered all-wheel drive. Key-wise it sits between its predecessor and the later Taurus: the turned ignition and 40-bit 4D63 chip carried over from the Freestyle, but the key itself gained remote buttons in its head. Parts for it are still easy to find.
• Thunderbird (2002–2005). The retro two-seat Thunderbird convertible of 2002-2005 shared its platform with the Lincoln LS and Jaguar S-Type, came with a 3.9-liter V8, and offered a removable hardtop with porthole windows. Production ended in 2005. Its keys changed in the middle of the run: the 2002 car uses a 4D60 chip key, while 2003-2005 cars use the 4D63 key common to other Fords of the time. In every year, keyless entry is a separate four-button remote.
• Transit (2015–2026). The full-size Transit replaced the E-Series cargo and passenger vans for 2015 and is sold as a van, cutaway and chassis cab, with the battery-electric E-Transit added for 2022. Its keys follow Ford's European-influenced hardware: a side-milled HU101 remote-head key at launch, flip keys and optional smart fobs after the 2020 refresh. Fleet vans often carry several different keys, so knowing which version you have matters.
• Transit Connect (2010–2023). The compact Transit Connect was sold in the US from 2010 through 2023. The first version was a Turkish-built import with a European-style Tibbe key; the redesigned 2014 model came in short and long wheelbases, including a passenger wagon, and switched to Ford's HU101 key. A 2019 refresh brought flip keys and an optional smart fob. Each of its three key designs needs different cutting equipment, which is why the model year matters before we head out.
• Windstar (2000–2003). The Windstar was Ford's front-drive minivan through the 2003 model year, after which the Freestar replaced it. The second-generation van, sold from 1999, added a driver's-side sliding door, and many offered power sliding doors. Its key changed during the run: 2000 vans use the older 4C fixed-code chip, while 2001-2003 vans use the 4D63 key. Keyless entry is a separate remote, with extra door buttons on vans with power sliding doors.
• ZX2 (2000–2003). The ZX2 was the two-door sport coupe of the Escort family, sold as the Escort ZX2 at first and simply as the ZX2 once the Escort sedan went fleet-only, through the 2003 model year. It's a light, simple car with a turned ignition and an optional separate remote. Whether a given ZX2 has a transponder chip is the main question for a locksmith, so we check the key and the dash before cutting anything.

Common Ford key problems

• A flashing theft light with a crank and no start, or an engine that fires and dies after a second, usually means PATS didn't read the key. A cracked head that lost its chip, or a hardware-store copy with no transponder, is the usual cause.
• Two chip keys hanging side by side, or a metal gadget pressed against the key head, can confuse PATS. Ford's manuals warn about this, and a truck that starts once the extra keys come off the ring has a healthy key.
• Ford fobs come in 315 MHz, 434 MHz and long-range 902 MHz versions, and two fobs that look identical may not be interchangeable. We match the FCC ID printed on your old fob, or decode the VIN, before ordering a replacement.
• Battery sizes changed over the years. Separate remotes, remote-head keys and flip keys mostly take a CR2032, while most Ford smart fobs from about 2017 on take a thicker CR2450. Inland Empire heat shortens either one, so read the old cell before buying.
• With only one programmed key, Ford's do-it-yourself spare routine is off the table because it needs two working keys. Adding a second key while the first still works is far simpler than an all-keys-lost visit later.
• MyKey, which spread across the lineup from about 2010, lets an admin key limit top speed and audio volume on another key. A newly programmed key carries no restrictions until you set MyKey up again in the vehicle menu.
• Many Fords carry a SecuriCode keypad on the driver's door or pillar. The five-digit factory code is printed on a wallet card in the owner's packet, and if that card is lost, the code can usually be read with a scan tool.
• On high-mileage trucks and SUVs from the 2000s, a key that sticks or won't turn usually points to worn ignition wafers or a key copied from a copy. A key cut fresh to factory code often turns smoothly again, and badly worn cylinders can be rebuilt.

Dealer or mobile locksmith?

Price and parts are the other half of the comparison. Dealers typically sell factory keys only and charge their posted service rates for programming. We offer factory keys where it matters and quality aftermarket alternatives where they perform well, and the quote covers cutting, programming and the trip, with nothing tacked on at the end. Timing differs too. Dealer service departments generally keep business hours, while we take automotive calls every day from 6:30 a.m. to 11:30 p.m., which covers early commutes and late evenings. We're closed overnight, and we'll be upfront if your timing means the dealer or a next-day visit is the better plan. Neither option is wrong; the right one depends on your car and your schedule.

How the job works

1. Identify the exact key your car uses. Every job starts with the VIN, the trim and a look at any key you still have. From those we confirm the keyway, the transponder or smart-key chip, the remote frequency, the FCC ID and the button layout. Two Ford car keys that look identical can carry different electronics, so this step keeps the wrong part from ever reaching the car.
2. Verify ownership before any work. California holds licensed locksmiths responsible for knowing whose car they're making keys for. We record your name, the VIN and the plate on a work order. If you aren't the registered owner, you'll need the owner's written authorization along with your own photo ID before we begin.
3. Get the key code or decode the lock. A key is cut from a code, not a guess. When the factory code can be retrieved through manufacturer channels after ownership is verified, we use it. When it can't, we decode a door lock with a pick-decoder tool that reads the wafer positions without damaging anything, then work out any missing cuts.
4. Cut the blade on-site. Cutting happens right beside your car. For a smart key, that means the emergency blade hidden inside the fob; for a transponder or remote-head key, it's the main blade you'll use every day. We deburr the cuts and check the fit in each lock so nothing binds or sticks later on.
5. Program the chip, remote or smart key. Programming tells the car's computers that the new key belongs to the vehicle. Transponder chips are added to the immobilizer, remote buttons to the body control module, and proximity fobs to the keyless system. If a step requires dealer-only access on your car, you'll have heard that before we arrived, not halfway through the job.
6. Test everything and clear out old keys. Before we leave, every function gets checked: doors, trunk or liftgate, panic button, remote range, engine start, and the emergency blade in the driver's door. If keys are missing, we delete them from the car's memory where the system allows, so a lost key can no longer start the engine.

Proof of ownership

Before we cut or program a key for any vehicle, we verify that you have the right to it. Please have two things ready: the current registration or the title, and a government-issued photo ID with a matching name. We also check that the VIN on those documents matches the VIN plate on the dashboard. If the registration is locked inside the car, that's fine; we open the vehicle first, check the paperwork in the glove box, and only then make the key. If something doesn't line up, we stop and sort it out before any key is made.

Ford keys in Cerritos

Cerritos is about 65 miles from our San Bernardino base, roughly 66 minutes in light traffic via I-215 South through Colton and Riverside to SR-91 West. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment. Most trips into Cerritos use I-605 for at least part of the drive, and the technician keeps an eye on live traffic along the way so the arrival estimate you heard on the phone stays honest.

Planning a non-urgent job like a rekey, a smart lock install or a safe combination change? Every day of the week, appointments are available from first thing in the morning into the late evening, with 11:30 p.m. as closing time. Fridays and Saturdays follow the same schedule.
