Toyota Key Replacement in Arcadia, CA

How Toyota keys and immobilizers work

Toyota phased in transponder immobilizers model by model, so two Toyotas from the same year can need very different keys. Starting with the 1998 model year, the Camry, Avalon, 4Runner, Sienna and Land Cruiser used a fixed-code Texas 4C chip, while US Corollas, the Echo and other economy models kept plain mechanical keys into the mid-2000s. Between 2003 and 2005, depending on the model, the encrypted Texas 4D-67 chip took over. Around 2010 came the 80-bit G chip, and from about 2014 the 128-bit H chip, also called 8A. Many of these later keys carry a stamped D, G or H on the blade. Smart keys spread to US Toyotas with cars like the 2004 Prius, 2005 Avalon and 2007 Camry, moved to 128-bit fobs in the 2010s, and since about 2022 Toyota has used a newer generation: Texas 8A BA-type fobs in models such as the bZ4X and Crown, and NXP Hitag AES, often called 4A, in the Corolla, Corolla Cross and 2025 Camry. Partner-built cars follow their partner's rules, so the 86 and GR86 use Subaru systems and the GR Supra uses BMW's. The letter on your blade, the FCC ID on your fob and your VIN tell us which system we are working with.

Toyota key programming

Most Toyota key work runs through the OBD-II port with professional equipment. On 4C cars, a spare can often be cloned from a working key onto a new chip, while 4D-67, G and H keys are registered to the immobilizer itself. Some 4D-67 and G-chip Toyotas also accept an on-board add when you have a working black master key, and Toyota's door-and-key routine pairs most separate remotes and remote-head buttons without a computer. Smart keys always need a programmer. Many 2004-2020 fobs can be professionally reset and reused, but fobs from the newest systems may not be reusable at all. Blades matter too: most Toyota chip and remote-head keys use the TR47 profile, while smart keys hide a laser-cut emergency blade that has to be cut so you can open the driver's door when the fob dies. Before any of this, we check your ID and registration, and we quote the whole job before starting.

All Toyota keys lost

Losing every Toyota key is solvable in most cases, but the method depends on the system. On 4D-67 and G-chip cars, our equipment resets the immobilizer through OBD-II, usually after a built-in security wait, and then registers new keys. H-chip and 8A smart key cars usually need an emulator or a direct connection at the immobilizer or smart key box, which can mean removing a panel under the dash. Older 4C cars and early smart key systems may need the module's memory read on the bench. Toyota's newest BA and Hitag AES systems have aftermarket all-keys-lost coverage on many models but not all, and the BMW-built GR Supra is a dealer job. We confirm your VIN before driving out, verify ID and ownership on site, and program at least two keys.

Toyota models we cover

• 4Runner (2000–2026). Toyota's body-on-frame 4Runner has been sold in the US since the 1980s, and model years 2000 through 2026 run from the end of the third generation to the sixth. Its keys track Toyota's immobilizer history closely: a 4C chip key at the start, then 4D-67 and G chip keys, H-chip remote-head keys for 2020-2021, and smart keys that became standard on every trim for 2022. The 2025 redesign carries Toyota's newest smart key family. Because trim decided the key for years, the start method on your dash matters as much as the model year.
• 86 / GR86 (2017–2026). Toyota's small rear-drive coupe was co-developed with Subaru and built by Subaru alongside the BRZ. The first-generation car was sold in the US as the Scion FR-S through 2016 and as the Toyota 86 for 2017-2020; after a one-year gap, the second generation arrived for 2022 as the GR86. Because Subaru builds it, its keys are Subaru-supplied parts with Toyota logos, so a key or fob from a Camry or Corolla won't work even when it looks similar.
• Avalon (2000–2022). The Avalon was Toyota's full-size front-drive sedan, built in Georgetown, Kentucky, and sold in the US through the 2022 model year. Over four generations in this range it went from a 4C chip key with a separate remote to some of Toyota's earliest US smart keys, and then to push-button start on every trim from 2013. Hybrid versions joined for 2013; their fobs sometimes carry a blue hybrid logo and, in a few years, a different part number from the gas car's.
• bZ Woodland (2026–2026). The bZ Woodland is Toyota's all-electric crossover with an outdoor bent, added to the US lineup for the 2026 model year with standard all-wheel drive, 8.4 inches of ground clearance and a 3,500-pound tow rating. It sits alongside the refreshed bZ. Like Toyota's other battery-electric vehicles it has no key slot to worry about, but the car is so new that supplier fob data is thin, so we check your VIN against our equipment and fob suppliers before ordering a replacement or quoting any key work.
• bZ4X / bZ (2023–2026). The bZ4X was Toyota's first mass-market battery-electric crossover, developed with Subaru alongside the Solterra and sold in the US for the 2023 through 2025 model years. Every bZ4X uses push-button start and one of Toyota's newer smart key systems. For 2026, Toyota refreshed the model and renamed it simply bZ in North America, and that refreshed car has its own entry at the end of the list because supplier fob details for it were still settling.
• C-HR (2018–2026). The C-HR was Toyota's small, coupe-styled crossover, sold in the US for the 2018 through 2022 model years and offered only with front-wheel drive. Toyota chose not to bring the second-generation hybrid C-HR to the US. Its keys depend on trim: lower grades used a three-button flip key and a turned ignition, while upper grades got a smart key with push-button start. A battery-electric C-HR arrived for 2026 as a different vehicle and has its own entry.
• Camry (2000–2026). The Camry has been one of America's best-selling cars for this whole period, and from 2000 to 2026 it spans six generations, gas and hybrid. Few nameplates show Toyota's key history as clearly: a 4C chip key in 2000, 4D-67 and G chip keys through the 2000s, H-chip remote-head and flip keys in the 2010s, smart keys on better-equipped cars from 2007, and an all-hybrid 2025 redesign with a Hitag AES smart key. Because trim and build date both matter, we confirm by VIN.
• Celica (2000–2005). The seventh-generation Celica, a front-drive liftback coupe sold in GT and higher-revving GT-S form, was the last Celica sold in the US, covering the 2000 through 2005 model years. It shared engines with the Corolla and Matrix of the time and, like those cars in the US, it is generally listed with simple TR47 keys rather than the chip keys Toyota fitted to the Camry and 4Runner. That makes most Celica keys among the easier Toyota jobs.
• Corolla (2000–2026). The Corolla is Toyota's compact sedan, joined by a hatchback from 2019. From 2000 to 2026 it spans five generations, and its key history differs from bigger Toyotas: US Corollas used plain mechanical keys until a 4D-67 chip arrived around 2005, then G and H chips, smart keys on upper trims from 2014, and Hitag AES smart keys from the 2023 refresh. The performance GR Corolla and the Corolla Cross crossover have their own entries.
• Corolla Cross (2022–2026). The Corolla Cross is a subcompact crossover built on the Corolla's TNGA-C platform, assembled for the US in Huntsville, Alabama, and sold from the 2022 model year, with a hybrid added for 2023 and a refresh for 2026. It used one of Toyota's newer key systems from the start: a Hitag AES smart key on most cars. Supplier catalogs also list a keyed ignition cylinder for these years, so some base models start with a turned key, and the start method on your dash decides which key you need.
• Corolla iM (2017–2018). The Corolla iM was a five-door hatchback Toyota sold for the 2017 and 2018 model years, after the same car wore Scion badges as the iM for 2016. It is based on the European Auris rather than on the Corolla sedan, so its key system differs from the sedan's of the same years. It keeps a turned ignition and uses a flip key with an H transponder chip. Toyota dropped the name when the 2019 Corolla Hatchback arrived, and that newer car is covered under the Corolla.
• Crown (2023–2026). The Crown name returned to the US for 2023 after five decades away, as a raised, hybrid-only sedan with all-wheel drive on every trim. It sits above the Camry in Toyota's lineup and uses push-button start and one of Toyota's newer smart key systems throughout. The related Crown Signia wagon, added for 2025, is a separate model. Crown fobs are newer and less common than Camry fobs, so we confirm your VIN before ordering one or quoting a lost-key job.
• Crown Signia (2025–2026). The Crown Signia is a two-row hybrid crossover that Toyota added to its US lineup for the 2025 model year, effectively taking the place of the Venza. It shares a name with the raised Crown sedan but is a separate model with its own body and parts. Every US Signia is a hybrid with standard all-wheel drive, sold in XLE and Limited grades, and starts with a button. With a model this new and this low-volume, we check your VIN against our equipment and fob suppliers before quoting any key work.
• Echo (2000–2005). The Echo was Toyota's entry-level subcompact, sold in the US for the 2000 through 2005 model years as a tall four-door sedan and a two-door coupe, and later replaced by the Yaris. It is one of the simplest Toyotas to key: US-market Echos are listed with plain mechanical keys and no immobilizer, so a lost key is usually a cutting job rather than a programming job. Any keyless entry uses a separate remote that pairs on its own.
• FJ Cruiser (2007–2014). The FJ Cruiser was Toyota's retro-styled off-roader, built on the same truck platform as the 4Runner and sold in the US for the 2007 through 2014 model years. Every FJ starts with a turned key. Its key changed once in an important way: trucks through 2009 use a 4D-67 chip and trucks from 2010 use the 80-bit G chip, so the two keys aren't interchangeable even though they look the same and share the TR47 blade.
• GR Corolla (2023–2026). The GR Corolla is Toyota's turbocharged, all-wheel-drive performance hatchback, built in Japan and sold in the US from the 2023 model year with a three-cylinder engine and, from 2025, an optional automatic. It shares its body and electrical architecture with the Corolla Hatchback, including push-button start and a Hitag AES smart key, but its fob is a three-button part of its own. Because it is a low-volume car, we confirm your VIN before ordering a replacement fob.
• GR Supra (2020–2026). The GR Supra revived Toyota's Supra name for the 2020 model year. It was developed with BMW and is built by Magna Steyr in Graz, Austria, alongside the BMW Z4, and Toyota announced 2026 as the final model year for this generation. Under the Toyota badge, its key system is BMW's: a BMW-style smart key, a BMW body control module and BMW programming procedures. That makes it a very different job from any other Toyota.
• Grand Highlander (2024–2026). The Grand Highlander is Toyota's largest three-row crossover, built in Princeton, Indiana, on the TNGA-K platform and sold from the 2024 model year in gas, hybrid and Hybrid MAX form. It is a separate model from the regular Highlander, with its own smart key part numbers. Every trim uses push-button start and one of Toyota's newest smart key systems, which is why we confirm your VIN before ordering a fob or quoting a lost-key job.
• Highlander (2001–2026). Toyota's midsize crossover arrived for the 2001 model year as a car-based alternative to the 4Runner and has stayed one of the brand's core family vehicles through four generations. Its keys track Toyota's technology almost year by year: a fixed-code 4C chip at launch, the 4D-67 dot key from 2004, G and H chips after that, smart keys on upper trims from 2008, and push-button start on every truck from 2020. Hybrid versions generally follow the key hardware of the gas models from the same year. The larger Grand Highlander, sold from 2024, is a separate model with its own fobs.
• Land Cruiser (2000–2026). Toyota's flagship body-on-frame SUV covers three distinct eras in the US. The 100 Series ran through 2007 with conventional transponder keys, the 200 Series from 2008 to 2021 brought standard push-button smart keys, and after a two-year gap the smaller J250 returned the name for 2024 with Toyota's newest smart key family. Land Cruisers stay on the road for decades, so keys from every era are still in use. Lexus sells close relatives of each generation, but fobs are not interchangeable between the two brands.
• Matrix (2003–2013). The Matrix was a Corolla-based five-door hatchback sold in the US from the 2003 through 2013 model years, built in Cambridge, Ontario, and engineered alongside the Pontiac Vibe. Every Matrix has a turn-key ignition. Key catalogs list a plain mechanical key for 2003-2004 cars and a transponder key from 2005, which keeps key work simple next to later Toyotas. The first generation pairs its key with a separate four-button remote, while the second generation moved to remote-head keys, with the 80-bit G chip phasing in around 2010.
• Mirai (2016–2026). The Mirai is Toyota's hydrogen fuel-cell sedan, sold new in the US primarily through California dealers since the first deliveries in late 2015. The first generation (2016-2020) was a front-drive four-door with a distinctive wedge shape, and the larger rear-drive second generation arrived for 2021. Both use push-button start with a proximity smart key, and neither has a turn-key version. With a small fleet and few dealers servicing fuel-cell cars, keeping a working spare fob is especially worthwhile.
• MR2 Spyder (2000–2005). The MR2 Spyder was Toyota's mid-engine two-seat roadster, sold in the US from the 2000 through 2005 model years. In key terms it is a simple car: a turn-key ignition, a fixed-code Texas 4C transponder immobilizer, and keyless entry that, where fitted, came from Toyota's accessory remote system shared with the Celica and Echo. Spyders are now enthusiast cars that often change hands with a single worn key, so making a cloned spare early avoids the slower all-keys-lost job later.
• Prius (2001–2026). Toyota's hybrid has been sold in the US since the 2001 model year, first as a compact sedan and from 2004 as the familiar hatchback, and its keys have often been a step ahead of the rest of the lineup. The first generation used a conventional key, the 2004 redesign introduced a slot-and-button fob with an optional Smart Key, and every Prius since 2010 has push-button start with a proximity fob. Plug-in versions, the Prius Plug-in and later the Prius Prime, have their own entry and sometimes add an extra climate button.
• Prius c (2012–2019). The Prius c was Toyota's smallest hybrid, a subcompact hatchback sold in the US from the 2012 through 2019 model years. Unlike the larger Prius, it offered a conventional key ignition on its lower trims, with a remote-head key that turns in the column, while better-equipped versions use a proximity smart key and a POWER button. That split means the right replacement depends on how your car starts, not only on its model year, so we ask about the dash before quoting anything.
• Prius Prime / Plug-in (2012–2026). Toyota sold its plug-in Prius twice in this range: the Prius Plug-in Hybrid for 2012 through 2015, built on the third-generation Prius, and the Prius Prime from 2017, redesigned alongside the Prius for 2023. Every plug-in uses push-button start and a proximity smart key, and the fobs resemble the matching Prius fobs, sometimes with an extra climate button. The part number often differs from the regular Prius even when the shape looks the same, so we confirm the FCC ID and your VIN before ordering a replacement.
• Prius v (2012–2017). The Prius v was the wagon of the Prius family, sold in the US from the 2012 through 2017 model years with extra cargo space and the drivetrain of the third-generation Prius. It uses push-button start with a proximity smart key, and its fob family overlaps with the regular Prius and the first-generation Venza, which keeps replacements easy to find. The main thing to confirm before ordering is the FCC ID and board number printed on the back of your existing fob.
• RAV4 (2000–2026). The RAV4 is Toyota's compact crossover, and this range covers six generations, from the last year of the original small RAV4 in 2000 to the all-new sixth generation for 2026. Early RAV4s use a plain key with a separate remote, the 2006 redesign brought remote-head keys and an optional smart key, and later generations moved steadily toward push-button start, which is standard on the hybrid-only 2026 model. The RAV4 Hybrid (from 2016) and RAV4 Prime (2021-2024, renamed the RAV4 Plug-in Hybrid for 2025) use their year's key hardware, with the Prime's fob adding a climate button.
• Sequoia (2001–2026). The Sequoia is Toyota's full-size three-row SUV, built on Tundra underpinnings and sold since the 2001 model year. Its key history differs from the Tundra's in useful ways: the Sequoia launched with a transponder immobilizer, kept a turn-key ignition through 2019, and got push-button start on every grade for 2020. The third generation, launched for 2023 as a hybrid-only SUV, uses Toyota's newest smart key family shared with the Tundra, Tacoma and Land Cruiser.
• Sienna (2000–2026). Toyota's minivan covers four generations in this range, from the late first-generation vans of 2000-2003 to the hybrid-only fourth generation launched for 2021. Sienna remotes are unusual because many carry buttons for one or two power sliding doors and the power liftgate, so the right replacement depends on your van's equipment as well as its year. Transponder chips followed Toyota's usual path from 4C to dot, G and H keys, and smart keys spread from upper trims in 2011 to every van in 2021.
• Solara (2000–2008). The Camry Solara was Toyota's two-door coupe and convertible, sold in the US from the 1999 through 2008 model years, with the second generation arriving for 2004. Built on Camry mechanicals, it shares much of its key hardware with the Camry of the same years: a fixed-code 4C key on the first generation and a dot-chip 4D-67 key on the second. Every Solara has a turn-key ignition, which keeps replacement keys straightforward, though the 4C cars need more work if every key is lost.
• Tacoma (2000–2026). The Tacoma is Toyota's midsize pickup, and this range runs from the last first-generation trucks of 2000-2004 to the fourth generation that launched for 2024. Its key story is a steady climb: no factory immobilizer on early trucks, a dot-chip key from 2005, G and H chips after that, a smart key on Limited models from 2016, and push-button start across the fourth generation. Many Tacomas change hands with only one key, so a spare is worth making before the original wears out or goes missing.
• Tundra (2000–2026). The Tundra is Toyota's full-size pickup, sold since the 2000 model year and now in its third generation. Its key technology lagged the related Sequoia at first: early Tundras have no factory immobilizer, the 2007 redesign brought transponder keys, and Toyota added Smart Key with push-button start to many trucks for 2020 before making it standard with the 2022 redesign. Because Tundras stay in service for many years and many miles, we work on keys from every era of the truck.
• Venza (2009–2024). The Venza is a two-row crossover Toyota sold in two separate runs: a Camry-based, wagon-like model for 2009-2015 and a hybrid-only second generation for 2021-2024, after which the Crown Signia replaced it. The two share a name but nothing in their key systems. The first generation was sold with both turn-key and smart-key setups, while every second-generation Venza uses push-button start with Toyota's newest fob family, and it was one of the first Toyotas to get that fob.
• Yaris (2007–2020). Toyota sold the Yaris in the US from the 2007 through 2020 model years, and the name covered three quite different cars: Toyota's own subcompact hatchback and sedan (2007-2011), a redesigned Toyota hatchback (2012-2018), and Mazda2-based models, first the Yaris iA sedan from 2017 and then the Yaris sedan and hatchback through 2020. The Toyota-built cars use turn-key transponder ignitions, while the Mazda-built ones use Mazda's push-button smart key. Knowing which car you have is the first step to the right key.

Common Toyota key problems

• Toyota chip keys are easy to mix up. Many later keys are stamped near the head with D for the 4D-67 chip, G for the 80-bit G chip or H for the 128-bit H chip, and a key ordered by looks alone often won't program.
• Toyota fob batteries vary by family. The 2009-2012 Camry-style smart key takes a CR1632, many 2016-2022 fobs take a CR2032, and larger 2022-and-later fobs take a CR2450. Most remote-head keys use a CR2016, while older separate remotes use a CR2032.
• If a smart key battery dies, most push-button Toyotas will still start. Press the brake and touch the Toyota emblem side of the fob to the start button; the car reads the chip directly, so a flat cell isn't a lockout.
• Many newer Toyota fobs have a battery-saving mode, switched on by holding lock and pressing unlock twice. Afterward the car ignores the fob in your pocket until a button is pressed, which owners often mistake for a dead key.
• Toyota smart keys look alike across models but carry different FCC IDs and board numbers. Suppliers warn, for example, that a 2007-2010 fob with an E board won't substitute for one with a numbered 0140 board.
• Remote-head keys take a beating on a key ring: the plastic head cracks and the rubber button pad tears. The chip and circuit board usually survive, so a new shell and freshly cut blade often fix the problem.
• Older Toyotas came with black master keys and gray valet keys. The valet key starts the car but can't be used for Toyota's on-board method of adding keys, so a car with only valet keys left needs programming equipment.
• A used Toyota smart key bought online is already locked to its first car. Many 2004-2020 fobs can be professionally reset for reuse, but fobs from the newest systems may not be resettable, so buying used can waste money.

Dealer or mobile locksmith?

The biggest difference between a dealership and a mobile locksmith is where the work happens. A dealer programs keys in its service bay, so if every key is lost, the car usually has to be towed there, and you work around the service department's schedule and the time it takes to order a key by VIN. Julian's Locksmith brings the cutting machine, key blanks and programming equipment to the car, whether it sits in your driveway, a workplace lot or a parking structure. For a Toyota car we can program on-site, that means no tow and no shuttle rides back and forth. The trade-off is real, though: on vehicles where only the dealer can program keys, a tow or appointment may still be necessary, and we'll say so before you spend anything on our visit.

How the job works

1. Identify the exact key your car uses. We ask a few quick questions on the phone: the year, whether the car starts with a turn key or a button, how many keys you have left, and whether the remote still works the doors. Then we check the VIN against our programming references so the van arrives with the correct blank or fob, not a close guess.
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. Our van carries a code-cutting machine that handles both traditional edge-cut blades and the laser-cut, side-milled profiles common on newer keys. The blade is cut to the code, then test-fitted in a door lock and the ignition or emergency keyhole to confirm smooth operation before any programming begins.
5. Program the chip, remote or smart key. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Toyota system, this may involve a security PIN, a timed waiting period, or on-board button sequences for the remote. On some vehicles we clone a working key's chip instead, when that's the more reliable path.
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

Not every situation fits the simple case, so here's how we handle the common exceptions. For a leased or financed vehicle, a registration that lists you as the registered owner or lessee works with your ID. If you just bought the car, bring the signed title or bill of sale along with your ID. For a company or fleet vehicle, we need written authorization from the business plus the driver's ID. If the car belongs to a family member, the registered owner should be present or provide signed permission and a copy of their ID. Rental vehicles go through the rental company.

Toyota keys in Arcadia

Arcadia is about 46 miles from our San Bernardino base, roughly 50 minutes in light traffic via Palm Avenue to I-215 North, I-15 South to the SR-210/I-210 Foothill Freeway. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment. Stuck on the shoulder or in a parking lot along Orange Grove Avenue? Get somewhere safe, turn on your hazards, and give us the nearest exit or business so we can find the car without guessing.

We start at half past six every morning, seven days a week. Every day the phones stay on until 11:30 at night, so an after-dinner lockout is usually still within reach. Saturday is no exception, with service ending at 11:30 at night. Call early that day if the problem can't wait until Sunday morning.
