Toyota 4Runner key replacement in Los Angeles

Toyota 4Runner keys by year

Which key does your 4Runner actually use?

A 4Runner key is not one part. Across the years in the table on this page, the same nameplate has used a fixed-code chip in a plain bladed key, a 4D-67 'dot' transponder key, an 80-bit G-chip remote-head key, a 128-bit H-chip remote-head key, and a push-button smart fob. Which one your truck needs decides what we cut, how we program it, and whether the job is routine or something we have to check before we promise anything.

Here is the short version of the four generations we work from:

If you are not sure which one you have, call (213) 577-1366 with the model year and VIN. Our wider Toyota key pages and the car key overview cover other models. This page is only about the 4Runner, and it is written the way we would explain it across the counter.

• N180, third generation, 1996–2002: a 4C fixed-code chip on trucks with the immobilizer. Some base trims may have no transponder at all.
• N210, fourth generation, 2003–2009: the 4D-67 'dot' era. 2003 is a changeover year where catalogs list both 4C and 4D-67.
• N280, fifth generation, 2010–2024: a G-chip remote-head key (HYQ12BBY) from 2010 through 2019, then an H-chip remote-head key (HYQ12BEL) from 2020 through 2024. A smart key is optional on Limited trims.
• N410, sixth generation, 2025–2026: push-button start is standard and an 8A DST-AES smart system is listed, but launch-year data is still maturing.

What 1996–2002 4Runners need (N180, third generation)

Third-generation trucks fitted with the immobilizer use a 4C fixed-code chip. For 2000, 2001 and 2002 our data is verified: it is a transponder key, programming runs through the OBD port, and no NASTF/SDRM registration is flagged. A working original key is needed to duplicate, an all-keys-lost job is possible, and there is a mechanical backup key.

The catch is the trim. Some base trucks of this generation may be non-transponder, so we confirm from the security light before we decide what to cut. A plain metal key and a chip key are different jobs, and it is better to find out which one you have before anything is ordered or cut. Our year data starts at 2000, so for a 1996–1999 truck we work from the generation note and confirm everything on the truck itself.

What owners of these trucks usually bring us: a key that has worn down until it barely turns the lock, a key that turns but will not start the engine, or a hardware-store copy that opens the door and does nothing else. That last one is the chip at work. A copy with no chip cannot start the engine. On high-mileage trucks the ignition wafers can also be worn, and a new key cut to the old, worn key will inherit that wear. Where we can, we cut from the key code or the lock rather than from a tired blade.

What 2003–2009 4Runners need (N210, fourth generation)

The fourth generation moved to the 4D-67 'dot' transponder. For 2004 through 2009 that is verified in our data: a transponder key, OBD programming, no registration flagged, an original key needed to duplicate, all-keys-lost possible, and a mechanical backup key.

2003 is the exception, and we are not going to pretend otherwise. It is the changeover year. transpondery.com lists both the 4C chip (through 2003) and the 4D-67 (from 2003), and our data marks the 2003 chip as conflicting rather than verified. The new N210 generally takes the dot key, but we check the key stamp or the VIN before cutting anything. If you own a 2003, expect us to ask for the VIN first. That one question avoids buying the wrong key.

The problems on these trucks are the same three we see on the older ones: worn ignition wafers on high-mileage vehicles, a worn blade that stops turning the lock, and non-chip copies that will not start the car. A key that has started to stick or needs jiggling is a warning. Making a spare while the original still works is the usually more economical route, because a duplicate with a key in hand is simpler than a job with no keys at all.

What 2010–2024 4Runners need (N280, fifth generation)

The fifth generation ran for fifteen model years, and it has two distinct key eras inside it.

The G-chip years, 2010 through 2019. The key is the HYQ12BBY remote-head key on the 80-bit G chip (4D-72). For 2010–2018 our data is backed by three sources and shows OBD programming with no registration flagged. 2019 is the last G-chip year per transpondery.com, but some catalog listings stop at 2018 and the H-chip key starts at 2020, so for a 2019 we look for the G stamp on the blade. Whether registration is required for 2019 is not settled in our data, so we confirm that too.

If your Limited has push-button start, tell us on the phone. Smart key is optional on Limited trims in this generation (the HYQ14ACX fob appears in the data), and that is a different fob and a different job from the standard remote-head key. We confirm that setup by VIN.

The H-chip years, 2020 through 2024. The key becomes the HYQ12BEL remote-head key with a 128-bit H chip on key-start trucks. Original-equipment key listings explicitly cover 2020–2021 production, transpondery.com carries the H chip through 2024, and no catalog we have seen shows a return to the older G key. We still check the H stamp on the blade. Programming is still through OBD, but the data flags NASTF/SDRM registration as required for every one of these years. Smart-key trims in this window use 8A fobs (HYQ14FLA listings cover 2021–2023).

The honest part: for all-keys-lost on 2020-and-later smart-key vehicles, jobs in the US generally need Toyota server codes through credentialed access (LSID/NASTF VSP). Toyota's reset bulletin T-SB-0013-24 covers the 2022–2024 4Runner. That access is a gate, not a formality. We confirm which route applies to your truck before we commit, and if the only workable path is the dealer, we say so.

What 2025–2026 4Runners need (N410, sixth generation)

The sixth generation is an all-new truck on the Tacoma platform, and push-button start is standard. transpondery.com lists the 8A (128-bit DST-AES) smart system. Our data for these years is marked unverified, and we would rather say that than guess.

What the data does not settle is the part owners care about most. The programming method is listed as unknown, and whether an all-keys-lost job can be done outside the dealer is not confirmed. Registration is flagged as required. Launch-year aftermarket coverage is still maturing, so all-keys-lost may need Toyota server access or dealer service. We confirm the exact setup by VIN and check current tool coverage before we quote. We will not take a deposit-style promise from you for something we have not confirmed.

A few things are clear. A working original key is needed to duplicate. There is a mechanical backup key. The common problems are fob battery failure that shows up as 'key not detected', water-damaged fobs, and the plain fact that a lost-fob replacement costs more than an older bladed key. If you have one good fob today, the sensible move is to deal with a spare now rather than after it goes missing.

Duplicate key or all keys lost: what changes by era?

Across every year in our data, duplication needs an original key that works. Having one in your hand makes the job simpler. All-keys-lost is listed as possible for 2000 through 2024, and unconfirmed for 2025–2026. But 'possible' does not mean the same thing in every era.

Making a spare while you still have a key is almost always the usually more economical route. Once the last key is gone, the job gets longer, needs more equipment, and in the newest trucks may involve Toyota's systems.

• 1996–2009 (4C and 4D-67): duplicates and all-keys-lost are both possible through OBD programming, with no registration flagged. The 2003 truck gets a VIN check first.
• 2010–2019 (G chip): the same picture with the remote-head key. For 2019, we confirm the G stamp and whether registration applies.
• 2020–2024 (H chip and 8A smart fobs): possible, but flagged as registration-required. All-keys-lost on smart-key trucks generally needs Toyota server codes through credentialed access.
• 2025–2026 (8A smart): duplicate with an original in hand is the clear path. All-keys-lost is not confirmed, and we check current coverage by VIN before quoting.

How we handle a 4Runner key job, step by step

Almost every year in our data lists OBD as the programming method, which means the work happens at your truck with the key blank and a programming tool. The two exceptions are in the data too: 2025–2026 lists the method as unknown, and 2020 onward is flagged for registration. So the first conversation matters more than anything else.

If a job depends on credentialed access we cannot complete, you will hear that on the phone, not after a van has arrived.

1. You call (213) 577-1366. It is answered 24 hours a day, every day. Give us the model year, trim, VIN, and whether you still have a working key.
2. We identify the generation and chip family from the data above. For 2003, 2019, any Limited with push-button start, and 2025–2026, we confirm by key stamp or VIN before ordering or cutting anything.
3. We tell you the route: OBD programming at your truck, or a job that needs server access, or one that belongs at the dealer.
4. A mobile van comes to the truck, or you bring the key to our storefront at 10740 Wilshire Blvd in Westwood. If you have lost every key, the van is the point, because the truck does not have to go anywhere.
5. We cut the blade, program the key, and test everything: starting, locking and unlocking, remote buttons, and the mechanical backup key.
6. You leave knowing exactly how many keys work, and with the old copy or shell sorted out if it was failing.

What affects the cost of a 4Runner key?

We do not publish numbers on a model page, because the honest answer depends on your truck. Here is what moves the cost.

Ask any locksmith, including us, what a quote covers before the work starts. A quote that leaves out programming or the blade is not a quote.

• Generation and chip family. A 4C or 4D-67 key is a simpler part than an H-chip remote-head key or an 8A smart fob.
• Key type. A plain bladed key, a remote-head key, and a smart fob have very different parts.
• Duplicate versus all-keys-lost. A duplicate with a working key is the lighter-cost option. All-keys-lost takes more equipment and more steps.
• Registration and server access. On 2020-and-later trucks, a job that depends on Toyota server codes adds work that older trucks do not have.
• How many keys you want. Programming a spare in the same visit is usually more economical than coming back for it.
• Whether your old remote still works. A cracked shell may be a smaller repair than a whole new key.

What goes wrong with 4Runner keys most often?

These are the problems our data lists by era. They are why we ask questions before we show up.

• 1996–2009: worn ignition wafers on high-mileage trucks, worn blades that stop turning the lock, and non-chip copies that open the door but will not start the engine.
• 2010–2024: cracked remote-head shells, worn buttons, and remote battery failure. A cracked shell does not always mean the electronics are dead, so bring the key.
• 2025–2026: fob battery failure with a 'key not detected' message, water-damaged fobs, and replacement costs that run higher than an older bladed key.
• Every era: a hardware-store copy without a chip will not start the car, and a spare made before the last key is lost is simpler than a replacement afterward.

When to call us, and when the dealer makes sense

Call us for most 4Runners from 1996 through 2019: lost keys, worn keys, spares, broken remote-head shells, and all-keys-lost where the key is not in your pocket and the truck is not going anywhere. For 2020–2024 we confirm the route first, and for 2025–2026 we confirm current tool coverage by VIN. If the only path is Toyota's server access or the dealer, we will tell you, and we will not hold you up while we find out.

Why call a company like ours? We have been in business since 1987, and David, the owner and lead technician, oversees the work. We run a storefront in Westwood plus mobile service vans, and we are one company, not a dispatch service that hands your call to whoever picks it up. We serve 140 cities across Los Angeles and Ventura counties, so wherever the truck is parked, the van comes to the truck.

One check you should make with any locksmith: California requires locksmith companies to hold a BSIS LCO license. Ask for it, and ask for it from us too. For more detail on our service, see the Wilshire Lock & Key home page or contact us with your year and VIN. If it is urgent, call (213) 577-1366. The phone is answered around the clock.
