Honda Key Replacement in Cerritos, CA

How Honda keys and immobilizers work

Honda's key systems changed in a few clear steps between 2000 and today, and the model year usually tells us which one your car has. In 2000 the Accord already carried a Megamos ID13 transponder in the key head, read by a coil around the ignition; the Civic followed for 2001 and the CR-V for 2002. Honda moved to Philips ID46 crypto transponders on the 2003 Accord and spread them across the lineup by about 2007, while the old edge-cut blade gave way to the laser-cut HON66 profile on most models. The same period brought remote-head keys, with lock and unlock buttons molded into the key itself. The 2013 Accord introduced Philips ID47 keys, often called Honda G keys, along with smart keys and push-button start on upper trims, and by the 2018 Accord every trim started with a button. Starting with the 2022 Civic, Honda began moving to AES-encrypted 4A fobs, now also used in the Accord and CR-V. On key-start Hondas, the key-shaped immobilizer light should go out a moment after you switch on; if it blinks, the car has not recognized the key.

Honda key programming

Honda gives owners no routine for adding transponder keys, so every key or fob is registered through the OBD-II port, either with Honda's dealer software or with professional equipment that runs the same security exchange. On many older Hondas the registration relearns the whole key set at once, and a key not presented during the session stops starting the car, so bring every key you want to keep. Remote buttons on many pre-2013 cars pair through a simple ignition-and-lock-button routine; newer remote-head keys and all smart keys are paired by the programmer. A replacement smart key must be new or professionally reset, and its emergency blade is cut separately, usually to the HON66 profile found on most Hondas since the early 2000s. For the 4A fobs on the 2022-and-later Civic and the 2023-and-later Accord and CR-V, coverage depends on the current version of our equipment. Before any programming, we check your ID and registration.

All Honda keys lost

Losing every key to a Honda built between 2000 and about 2021 is usually handled where the car sits. We decode the driver's door lock to cut a working blade, connect through the OBD-II port, register new keys, and erase the lost ones so they can no longer start the car. A 2000 Civic or a 2000-2001 CR-V has no transponder at all, so a correctly cut key is the whole job. Smart-key Hondas need a new fob plus a cut emergency blade. The newest systems, on the 2022-and-later Civic and the 2023-and-later Accord and CR-V, depend on current tool coverage, and some cases still have to go through a Honda dealer; we tell you which applies before any work starts. Expect to show ID and proof of ownership first.

Honda models we cover

• Accord (2000–2026). The Accord is Honda's midsize sedan, also sold as a coupe through 2017 and offered as a hybrid in several generations. Its keys trace Honda's whole key history: a chip key with a separate remote in 2000-2002, laser-cut remote-head keys from 2003, smart keys with push-button start on upper trims from 2013, push-button start on every trim from 2018, and 4A-encrypted fobs from 2023. Because trims within one generation can carry very different keys, a photo of your key or the FCC ID on the fob helps us quote accurately.
• Civic (2000–2026). The Civic is Honda's compact car, sold in the US as a sedan, coupe and hatchback, with Si, Hybrid, natural-gas and Type R versions along the way. Its keys changed with almost every generation: no transponder in 2000, an ID13 chip key with a separate remote from 2001, laser-cut remote-head keys from 2006, smart keys on upper trims from 2014, and 4A-encrypted fobs on every 2022-and-later car. Lower trims often kept a turn key long after upper trims went push-button, so the trim matters as much as the year.
• Clarity (2017–2021). The Clarity was Honda's alternative-fuel sedan, offered for 2017-2021 as a hydrogen Fuel Cell model and a battery Electric, both lease-only in limited states, and as the Plug-in Hybrid sold nationwide from the 2018 model year. All versions use a smart key with push-button start, and Plug-in Hybrid fobs add buttons for climate control and charging. Before this car, Honda leased the FCX Clarity fuel-cell sedan in Southern California from 2008 to 2014; it was never sold, and its keys were handled through Honda.
• CR-V (2000–2026). The CR-V is Honda's compact crossover and one of its best-selling vehicles, with hybrid versions from 2020 and a plug-in fuel-cell CR-V e:FCEV from 2025. Its key technology moved in steps: a plain key on 2000-2001 models, an ID13 chip key with a separate remote from 2002, remote-head keys from 2007, smart keys on top trims from 2015, smart keys on most trims from 2017, and push-button start on every trim from 2023. Because the LX kept a turn key while higher trims went push-button, check your ignition before ordering a key.
• CR-Z (2011–2016). The CR-Z was Honda's two-seat sport hybrid hatchback, sold in the US for model years 2011 through 2016 with a manual or CVT transmission. Most cars use a turn key with a remote-head design shared with other Hondas of the period, so replacement keys are easy to source. The 2016 update added Smart Entry with push-button start, making that final year the only CR-Z with a smart key. Production was modest, so for 2016 smart keys we confirm part availability by VIN before scheduling.
• Crosstour (2010–2015). The Crosstour was a fastback crossover built on the Accord, sold as the Accord Crosstour for 2010 and 2011 and simply as the Crosstour from 2012 until it ended after the 2015 model year. Early cars use a Philips ID46 remote-head key of their own. The 2013 refresh moved the remote-head key to Honda's ID47 G chip and added a smart key with push-button start on upper trims. Four-cylinder and V6 models use the same key for their year and trim.
• Element (2003–2011). The Element was Honda's boxy, CR-V-based utility vehicle with rear-hinged side doors, sold for model years 2003 through 2011 in several trims, including the street-styled SC. Every Element uses a turn key with a transponder and, on trims with keyless entry, a separate three-button remote rather than buttons on the key. The transponder chip changed partway through the run, so the model year matters when ordering a key. Its laser-cut key and simple remote make it one of the more straightforward Hondas of its age to make keys for.
• Fit (2007–2020). The Fit is Honda's subcompact hatchback, sold in the US for 2007-2008, 2009-2013 and 2015-2020, with no 2014 model year between the second and third generations. The first two generations use turn keys with the remote built into the key head. The third generation kept a remote-head key on the LX and other lower trims, while EX and EX-L models gained a smart key with push-button start. A battery-electric Fit EV was also offered on lease only for 2013-2014, with its keys supplied through Honda.
• HR-V (2016–2026). Honda's subcompact crossover arrived in the US for 2016 on the same small-car platform as the Fit, then was replaced for 2023 by a larger HR-V built on Civic underpinnings and sold in other markets as the ZR-V. The key story splits along that same line. First-generation LX models start with a remote head key, while the upper trims carry a smart key with push-button start. Every second-generation HR-V uses a smart key on Honda's newer AES-encrypted system, which changes what a spare or a lost-key job involves.
• Insight (2000–2022). Honda used the Insight name for three different hybrids. The 2000-2006 original was a lightweight aluminum two-seat hatchback, the 2010-2014 car was a five-door hatchback aimed at buyers who wanted a lower-cost hybrid, and the 2019-2022 Insight was a compact sedan built in Indiana on Civic underpinnings. Each one sits in a different Honda key era: a chip key with a separate remote, then a remote head key, then a smart key with push-button start. Telling us the model year is usually enough to know which key you need.
• Odyssey (2000–2026). Honda's minivan has gone through four US generations since 2000, and its keys track Honda's wider history. Through 2004 it used a Megamos chip key and a separate remote. Remote head keys and separate sliding-door remotes followed through 2013, smart keys reached upper trims for 2014, and push-button start became standard on every trim for 2018. The 2025 refresh brought a new series of fob part numbers. Because power sliding doors add buttons, Odyssey remotes come in more layouts than most Hondas, and the button count matters when ordering.
• Passport (2000–2026). The Passport name has covered very different SUVs. The 2000-2002 Passport was a rebadged Isuzu Rodeo built in Lafayette, Indiana, with Isuzu's key and remote hardware. Honda revived the name for 2019 as a two-row SUV built in Lincoln, Alabama, on the third-generation Pilot's platform, and the redesigned 2026 Passport, also built in Alabama, leans harder toward off-road use. The early truck uses a plain cut key, while every Passport since 2019 starts with a smart key and a push button.
• Pilot (2003–2026). Honda's three-row SUV launched for 2003 and has gone through four generations. The key setup changed with almost every redesign: a Megamos chip key and separate remote on early first-generation trucks, remote head keys from the mid-2000s through 2015, a smart key with push-button start on every trim from 2016, and Honda's AES-encrypted fob from 2023. Pilots also share fobs with other Hondas, including the Passport, Odyssey and CR-V, which helps with parts availability but makes checking the part number on your fob important.
• Prelude (2000–2026). The Prelude covers two separate eras. The fifth-generation coupe, sold here through the 2001 model year, has a Honda chip key and a separate remote. After a long break, Honda brought the name back for 2026 as a hybrid coupe with a liftback, built in Japan with Civic-related hardware, push-button start and a smart key. One is a turn-key car with simple, well-understood key options; the other is a new model whose aftermarket key coverage is still developing, so the model year tells us most of what the job involves.
• Prologue (2024–2026). The Prologue is Honda's electric midsize SUV, built by General Motors in Ramos Arizpe, Mexico, on the same Ultium-based platform as the Chevrolet Blazer EV. That shared engineering extends to the key: the Prologue's fob, immobilizer and programming come from GM's system rather than Honda's. For you, that means Honda's usual key procedures don't apply, replacement fobs are GM-designed parts sold through Honda dealers, and new keys are a dealer job for now. We can still help with lockouts and the emergency blade.
• Ridgeline (2006–2026). Honda's midsize pickup uses a unibody structure rather than a separate frame, and it has run in two US generations: 2006-2014 and 2017 onward, with no 2015 or 2016 models. The first truck uses a turn-key ignition with a remote head key, while every second-generation Ridgeline has a smart key and push-button start. Honda confirmed a third generation in 2026, but the current truck still covers the 2026 model year. Knowing which side of the 2017 break your truck sits on tells us most of what the key job involves.
• S2000 (2000–2009). Honda's front-engine, rear-drive roadster was sold here from 2000 through 2009, first as the AP1 with a 2.0-liter engine and from 2004 as the AP2 with a 2.2-liter. Its start sequence is unusual for a Honda: you insert the key and turn it to ON, then press a red engine start button on the dash. The immobilizer reads a chip in the key head before the engine will run, and keyless entry came from a separate remote. Many of these cars are garaged collectibles, so owners often want a spare before an emergency.

Common Honda key problems

• A blinking key-shaped light with a no-start usually means the immobilizer did not read the chip. Honda warns that another transponder key or metal key chain near the ignition can interfere, and a chip lost from a cracked key head causes the same symptom.
• Remote-head keys, used from the 2003 Accord onward, tend to fail at the plastic: the key-ring loop snaps, the head splits, or the blade works loose. The circuit board and transponder can usually be moved into a new shell instead of buying a whole key.
• High-mileage Hondas with laser-cut HON66 keys often develop worn ignition and door wafers, so the key must be jiggled to turn. A new key cut to factory code, not copied from the worn one, often turns cleanly; a badly worn cylinder needs repair.
• If a Honda smart key battery dies, slide out the built-in key to open the driver's door. To start, press the brake and touch the H logo on the fob to the ENGINE START/STOP button while the button blinks.
• Honda has recalled some early-2000s models because a worn ignition interlock could let the key come out while the shifter was not in Park. If yours does that, check recall status by VIN at nhtsa.gov.
• On several newer Hondas, including the 2018-and-later Accord, the driver's keyhole sits under a small cap on the door handle. The tip of the fob's emergency key pries the cap off, and it is easy to miss when you are locked out.
• Remote-head keys take small CR1616 or CR1620 cells, while smart keys use a CR2032. Inland Empire summer heat shortens their life, and shrinking remote range is usually the first warning before a fob stops responding.
• Separate keyless remotes on 2000-2002 Accords, 2001-2005 Civics, 2002-2006 CR-Vs and the Element often crack along the seam or lose battery contact. A replacement remote can usually be paired with an on-board ignition and lock-button sequence.

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 Honda 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.

Honda keys in Cerritos
