Toyota Highlander key replacement in Los Angeles

Toyota Highlander keys by year

Which Highlander key do you actually have?

A Highlander is not one key. Between 2001 and 2026 Toyota used four generations, and the key changes with each: a basic chip key, a remote-head key with a newer chip, a 128-bit chip key, and a push-button smart fob. Whether you need a spare, a replacement for a lost key, or a fix for a worn one depends on which of these is in your hand.

Wilshire Lock & Key has been cutting and programming keys since 1987. The year-by-year table on this page lists each model year; the text around it explains what that means for an owner. For the bigger picture, see our Toyota key service page or the car keys overview.

One note up front: in a few years our sources conflict or rest on a single listing. Where that happens we say so, and we confirm the exact setup from the VIN, the key stamp, or the key itself before we cut anything.

2001-2007: what do the first-generation Highlander keys need?

The XU20 Highlander uses a transponder key. The chip is the 4C type through 2003 and the 4D-67 'dot' chip from 2005; both are verified for those years. A key can be duplicated from a working original, or made from scratch if every key is lost.

2004 is the boundary year, and the sources disagree. One reference keeps the 4C chip through 2004, while several Ilco-aligned catalogs list the 4D-67 'dot' key from 2004. We do not guess. We check the key stamp or run the VIN first, because a key built for the wrong chip can turn the lock and still not start the car.

What owners of these Highlanders actually run into is age: worn ignition wafers on high-mileage cars, a worn blade that no longer turns the lock, and hardware-store copies that open the door but cannot start the engine because they have no chip. If your key is turning stiffly, a fresh cut is the first thing to try, and testing it tells us whether the ignition itself is tired.

2008-2013: when did the Highlander key move to the G chip?

The XU40 keeps the 4D-67 chip through 2009, and that is verified. From 2010 the key becomes a remote-head key, with the remote built into the head of the blade. The 80-bit G chip, also written 4D-72, is verified for 2011 through 2013.

2010 is another year where the sources conflict. One lists the G chip from 2010, while several catalogs keep the 4D-67 'dot' through 2010. We look for the G stamp on the blade before cutting, and if the stamp is worn or the key is missing, we confirm by VIN.

There is a catch for 2011 through 2013: a smart key with push-button start was optional on Limited and hybrid trims, so two Highlanders from the same year can have different keys. Tell us on the phone how yours starts. Our data on those optional smart systems is thin, so we identify the system from the fob in hand and the VIN rather than assume.

2014-2019: what changed with the H-chip Highlander?

The XU50 moves to the 128-bit H chip, verified across several sources. Key-start trims use H-chip bladed or remote-head keys in the TOY44H-PT family, with catalog fitment for 2014 through 2019. Smart-key trims use the 8A smart system with push-button start, and 8A-88 fobs show up in 2018 and 2019.

The easiest test: if you turn a key in the ignition, you are in the H-chip family. If you press a button with the fob in your pocket, you have the smart system, and the job is different. The table lists these years as remote-head keys, which describes the key-start setup; smart-key trims are the exception we sort out by VIN.

For 2018 and 2019 smart-key Highlanders, all-keys-lost may require Toyota pass-codes or credentialed access depending on the tool. Our data does not settle whether SDRM access is required for those two years, so we confirm for your car before choosing a route.

2020-2026: what do the smart-key Highlanders need?

The XU70 Highlander has a smart key with push-button start across the lineup. The fob type is 8A-AA for 2020 through 2022 and 8A-BA for 2023 and 2024, both verified. Each fob has a mechanical backup key.

Adding a key while you still have a working fob is less restricted. All keys lost is different: on 2020-and-newer smart-key cars, US jobs generally require Toyota server codes with locksmith-credentialed access through LSID and NASTF VSP. Programming goes through the OBD port, but the access behind it is what decides the job.

2025 and 2026 are unverified. One source lists a switch to NXP Hitag-AES 4A-BA smart keys, but we have not found a second source, and aftermarket fob listings for adjacent years still show 8A-family chips. We identify the system from the fob in hand and confirm by VIN. Aftermarket support for Toyota 4A systems is still maturing, so all-keys-lost on one of these may need Toyota server access or dealer service. We confirm current tool coverage before quoting.

Duplicate or all keys lost: what changes by era?

Copying a key you still have is the simpler job in every era. All keys lost is harder, and the gap widens as the cars get newer. Here is how it breaks down:

Making a spare while you still have a working key is the usual advice from any tradesperson, and it holds here. It is also usually the more economical route compared with an all-keys-lost job on the same car.

• 2001-2013: a duplicate from a working key and an all-keys-lost job are both possible, programmed through the OBD port with no NASTF/SDRM access required in our data. 2004 and 2010 get a stamp or VIN check first.
• 2014-2017: the same picture for H-chip key-start trims. Smart-key trims in these years we sort out by VIN.
• 2018-2019: both are possible, but on smart-key cars all-keys-lost may need Toyota pass-codes or credentialed access.
• 2020-2024: add-a-key with a working fob is less restricted. All keys lost generally needs Toyota server codes and credentialed access.
• 2025-2026: unverified. We confirm tool coverage before quoting, and the answer may be dealer service.

Is Highlander key programming done by OBD or dealer-only?

In our data, every Highlander year from 2001 on is programmed through the OBD port, so a locksmith can usually do the work without towing the car. What varies is the access behind that port. No NASTF/SDRM access is required through 2017, it is unsettled for 2018 and 2019, it is required for 2020 through 2024, and it is unknown for 2025 and 2026.

Dealer-only is not our default answer, but it is a real answer in some cases: an all-keys-lost 2020-or-newer Highlander where the Toyota server route is not open to us, and possibly a 2025 or 2026 where tool support is still catching up. If that is your situation we will tell you on the phone instead of sending a van for nothing.

When the job is ours, it goes like this:

1. You tell us the model year, the trim, and how the car starts: a key in the ignition or a button.
2. We identify the key from the VIN, the key stamp, or the fob. On boundary years such as 2004 and 2010 this step decides which blank we use.
3. We tell you which route applies: duplicate, add-a-key, or all keys lost, and whether any Toyota server access is involved.
4. We cut the blade and program the key at your car with a mobile van, or at our Westwood storefront if that suits the job better.
5. We test everything before we finish: starting, door locks, remote buttons, and the mechanical backup key.

What affects the cost of a Highlander key?

We do not put numbers on a web page, because the honest answer depends on your car. These are the things that move the cost:

We give you the cost for your Highlander once we know the year, how it starts, and what keys you have. Call (213) 577-1366 and we will walk through it.

• Key type. A chip key, a remote-head key, and a smart fob are very different hardware, and our data notes that replacing a lost fob costs more than replacing an older bladed key.
• Whether you still have a working key. Adding a key is generally less involved than an all-keys-lost job.
• Toyota server access. On 2020-and-newer smart-key cars, all keys lost may require server codes and credentialed access, which adds work.
• Number of keys. Programming two keys in one visit is usually more economical than coming back later for the second.
• Condition of the fob or ignition. A water-damaged fob or worn ignition wafers can change the job.
• Where and when. A van visit to your location, a storefront visit, and an after-hours call are not the same job.
• Boundary and unverified years. For 2004, 2010, 2025 and 2026 we confirm the setup first, which can change the parts needed.

What problems do Highlander keys usually have?

These are the problems our data lists for each era:

Before you assume a key is dead, try the simple things. On a smart-key Highlander, a 'key not detected' message is often a fob battery. On a remote-head key, a dead remote battery or a cracked shell does not necessarily mean the chip is gone, and we can test the chip and the remote separately.

• 2001-2009: worn ignition wafers on high-mileage cars, worn blades that stop turning the lock, and non-chip hardware-store copies that will not start the car.
• 2010-2019: cracked remote-head shells, worn buttons, remote battery failure, and the same hardware-store copy problem.
• 2020-2026: fob battery failure that brings up a 'key not detected' message, water-damaged fobs, and a lost-fob replacement that costs more than an older bladed key.

When should you call us instead of the dealer?

Call us when you have lost a key, need a spare, have a worn or broken key, or are stuck with a fob that will not work. We are one company: a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, with no dispatch middlemen between your call and the person doing the work. The phone, (213) 577-1366, is answered around the clock every day of the year, and we serve 140 cities across Los Angeles and Ventura counties.

David, the owner and lead technician, oversees the work, and we have been at this since 1987. You can reach us through the contact page or start from our home page.

The dealer may be the better call for a 2025 or 2026 Highlander with every key lost, or any 2020-and-newer car where Toyota server access is the only path. We would rather say that than start a job we cannot finish. Whoever you use, ask for their BSIS LCO license, which California requires of locksmith companies.
