Toyota Tundra key replacement

Toyota Tundra keys by year

Which Tundra key do you actually have?

The Tundra has been through three generations since 2000, and the key changed more than the truck's shape suggests. Our data splits them as XK30/XK40 (2000-2006), XK50 (2007-2021) and XK70 (2022-2026). Inside those, a plain metal key, a chipped bladed key and a push-button smart fob are three very different jobs with different tools and different paperwork behind them.

The year-by-year table on this page lists each model year. Treat it as a starting point, not the final word. Several years sit on boundaries where parts catalogs disagree with each other. Where that happens, we say so below and confirm the exact setup by VIN before we cut or program anything. That step is how you avoid paying for a key with the wrong chip in it.

A quick way to place your truck before you call:

• A plain metal key with no plastic head, and no security light behavior when you turn it: most likely a 2000-2002 truck, though we confirm from the security light before cutting.
• A bladed key with a thicker plastic head: a transponder key, which is the norm from about 2003 through 2021 on key-start trucks.
• A fob you carry in your pocket and a start button on the dash: the smart system. It is standard from 2022, and on 2018-2021 it appears only on Limited, Platinum and 1794 trims.
• Not sure, or the key is long gone: give us the VIN and we work out the rest from there.

What owners of 2000-2006 trucks (XK30/XK40) need

The 2000, 2001 and 2002 Tundras are the simple ones. Major transponder catalogs list no chip for those years, so most of these trucks run a plain mechanical key with no programming at all. That makes a spare cut by code or from the lock a straightforward job, and an original key is not required to make a copy. We still look at the security light first, because we would rather confirm than assume.

The 2003 and 2004 trucks are where the records disagree. One catalog lists the 4D-67 'dot' chip from 2003, other vendor listings start it at 2005, and some early trucks appear to be non-transponder. We do not guess here. We check the key stamp, the security light and the VIN, then decide whether your truck needs a chipped key or a plain one.

From 2005 through 2006 the 4D-67 chip is verified across the sources we use, and programming is done through the OBD port. A key from a hardware store that is only cut, without a chip, will turn the lock but will not start the truck.

Age is the other issue on these trucks. Worn ignition wafers on high-mileage trucks are common, and the door lock and ignition lock wear at different rates, so the door key may no longer turn the ignition. Sometimes the right fix is a new key. Sometimes the ignition needs attention first, and we will tell you which before you spend on a key that will not help.

What owners of 2007-2021 trucks (XK50) need

This generation covers fifteen model years and three different chips, so it is the one where the exact year matters most.

2007 through 2009 trucks use the 4D-67 chip, verified. 2010 is a conflicting boundary year: one catalog keeps the 4D-67 through 2010, while several remote and key listings start the 80-bit G chip that year. We check for the G stamp on the blade before cutting. 2011 through 2015 use the G (4D-72) chip, verified.

2016 and 2017 are the second boundary. One source lists the 128-bit H chip from 2016, another lists G-chip keys through 2017, and a third lists the TOY44H key from 2017. We identify the chip from the blade stamp or a key reader, and the VIN backs it up. Do not order a key online for these two years without that check.

2018 through 2021 use the H (128-bit DST-AES) chip, verified. Key-start trims take a TOY44H bladed key. Limited, Platinum and 1794 trucks use the 8A smart system with push-button start, and those are a different job from the bladed-key trucks, particularly if every key is lost.

For most owners of this era, the useful thing to do is make a second key while you still have a working one. With one original in hand, the job is routine on the bladed-key trims.

What owners of 2022-2026 trucks (XK70) need

The all-new XK70 Tundra moved to push-button start as standard, on the 8A-BA smart system. The 2022 through 2026 trucks are verified at that chip family in our data, with OBD programming and a mechanical backup key inside the fob.

The part to understand is all-keys-lost. Toyota's immobilizer-reset bulletin, T-SB-0013-24 (hosted by NHTSA), documents 2022-2024 Tundra all-keys-lost handling through a Toyota TIS pass-code. In the US, those jobs generally require locksmith-credentialed access (LSID/NASTF VSP). That is a gatekeeping step, not a quirk of one shop.

The 2025 and 2026 trucks carry over the same 8A-BA smart system. Current-model-year catalog data is still settling, so we confirm those by VIN too. If you still have one working fob, adding another is less restricted than starting from zero, and it is the easier call to make.

Duplicate key or all keys lost: how it differs by era

Everything in this section follows the data for your year, so use it to understand what to expect, not as a quote.

Making a copy is the lighter-cost, lower-stress situation in every era. All-keys-lost is possible on every year of the Tundra, but it takes more work.

• 2000-2002: no original key is needed to duplicate. All-keys-lost means cutting a new key to the lock, with no chip to program, though we confirm from the security light first.
• 2003-2004: an original key is needed for a straightforward duplicate. We settle whether the truck even has a chip before anything else.
• 2005-2021 key-start trucks: an original key is needed for a straightforward duplicate, and all-keys-lost is possible with OBD programming. The chip generation (4D-67, G or H) decides which key blank is correct.
• 2018-2021 smart-key trims and all 2022-2026 trucks: an original key is needed for a straightforward duplicate. All-keys-lost goes through Toyota server codes and credentialed access, covered in the next section.

Is Tundra key programming done at the OBD port or dealer only?

For every model year in our data, the programming method is OBD, meaning we connect to the truck's diagnostic port and program the key to the immobilizer there. Nothing in the data marks the Tundra as a dealer-only key from the factory side. The complication is access to Toyota's security data on newer trucks, not where the work happens.

Here is how that plays out. 2000-2002 trucks need no programming. For 2003 through 2017, the data shows no NASTF secure-data requirement. On 2018 and 2019 trucks the NASTF requirement is not settled in our data, and the note says all-keys-lost on smart-key trucks may require Toyota pass-codes or credentialed access depending on the tool. From 2020 through 2026 the data marks it as required for all-keys-lost on smart-key trucks, with Toyota server codes and locksmith-credentialed TIS access. Add-a-key with a working fob is less restricted.

So the honest version: on 2020 and newer trucks, a lost-every-key situation depends on credentialed access, and we will tell you plainly on the phone whether your truck's job is one we can complete or whether it needs to go through the dealer. We would rather say that up front than send a van and then tell you.

California also requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for that number before work starts, including us.

How a Tundra key job goes, step by step

The details change with the year, but the order of work is the same.

1. You call (213) 577-1366, any hour, and give us the year, trim and whether you have any working key. We ask about push-button start versus a bladed key.
2. We confirm the setup by VIN, especially for 2003-2004, 2010 and 2016-2017, where catalogs conflict.
3. We confirm you own the truck. Expect to show ID and registration or title, and the VIN on the dash should match.
4. We decide the route: the mobile van, if you are stuck or the truck will not start, or our storefront at 10740 Wilshire Blvd in Westwood, if you can bring the truck to us.
5. We cut the key blade to the lock, and where needed, check the fit in both the door and the ignition.
6. We program the key through the OBD port, or confirm the credentialed access path on 2020+ smart-key all-keys-lost jobs.
7. We test every key: lock, unlock, start the engine, and on smart trucks, the push-button and the backup blade.

What affects the cost of a Tundra key replacement?

We do not quote numbers on a web page, because an honest number depends on the truck in front of us. These are the factors that actually move the cost:

• Which era you are in. A plain mechanical key, a chipped bladed key and a smart fob are priced very differently because the parts and the programming steps are different.
• Duplicate or all-keys-lost. A copy from a working key is the usually more economical route. All-keys-lost takes more time and, on newer trucks, access to Toyota's security data.
• The chip and key blank. 4D-67, G and H keys are not interchangeable, and a wrong guess on a boundary year is a cost you pay twice.
• Smart fobs. Lost-fob replacement costs more than older bladed keys, and the fob itself is a larger part of the bill.
• Condition of the locks. Worn ignition wafers or a worn door lock on an older truck can add work that has nothing to do with the key.
• Where the truck is. A van visit to a stuck truck and a drop-off at our shop are not the same service, and we will say which one is lighter-cost for your situation.
• How many keys. Programming a second key during the same visit is usually more economical than coming back later.

Common Tundra key problems we see

The problems follow the data closely, and they differ by era.

• Worn ignition wafers on high-mileage trucks. This is common across the older and key-start trucks and causes sticking, or a key that turns only with effort.
• Worn or bent key blades. A key that no longer turns the lock is often a worn blade. Duplicating a worn key copies the wear, so a key cut from code or from the lock is often the better route.
• Door and ignition lock mismatch on 2000-2002 trucks. The door key can stop turning the ignition because the two locks wear at different rates.
• Non-transponder copies. A hardware-store copy turns the lock on a chipped truck but will not start it. The cut alone is not enough.
• Fob battery failure on 2022-2026 trucks. The dash shows 'key not detected.' Before assuming the fob is dead, try the battery, and use the backup blade or touch the fob to the start button if the truck allows it.
• Water-damaged fobs. A fob that has been through the wash or a soaked pocket can stop working outright, and may need replacing rather than repair.
• Lost-fob cost shock on newer trucks. People are often surprised by how much more a smart fob is than an older bladed key. Making a spare while you still have a working fob is the better plan.

When to call us, and when the dealer makes sense

Call us for most Tundra key jobs on 2000-2021 key-start trucks, whether you need a spare, replace a worn key, or lost every key. We are one company: the storefront in Westwood and our mobile vans work together, so there is no dispatch middleman between your call and the person doing the work. We have been in business since 1987, and David, the owner and lead technician, oversees the work. We serve 140 cities across Los Angeles and Ventura counties, and the phone is answered around the clock.

The dealer can make more sense in a narrow set of cases: a 2020-2026 smart-key truck with every key lost, where the job hinges on Toyota server codes and credentialed access. If we cannot complete your job, we will say so rather than start work we cannot finish. Call and we will give you a straight answer on which route fits.

Whichever way you go, ask for the company's BSIS LCO license number. If you are unsure about your key type, our Toyota key page and the wider car key replacement section cover other models. For anything else, start from our home page or contact us.
