GMC Key Replacement Cost in Fort Worth (2026): Sierra, Yukon, Acadia, Terrain, Canyon

As of September 2026, a GMC key replacement in Fort Worth from a mobile specialist runs $120–$250 for a transponder key, $150–$300 for a flip key with remote, $250–$450 to add a push-to-start fob, and $350–$650 or more when every smart key is lost. The model on the tailgate matters less than the key system under the dash, and the fastest way to know which band a specific GMC falls in is the VIN.

That is the short answer. The rest of this guide explains why the bands exist, which GMC models and trims land where, what changes the price inside each band, and when a lost GMC key is a quick add-key visit versus a longer all-keys-lost procedure. We cover Fort Worth, Arlington, Haltom City, Keller, Burleson and the wider Tarrant County area as a mobile service, so every figure here assumes the work happens at the truck.

Why GMC Key Prices Spread So Widely

GMC shares its platforms and its security architecture with Chevrolet. A Sierra and a Silverado of the same generation use the same key families and the same programming procedures, and a Yukon shares the underpinnings of a Tahoe. What GMC adds is trim variety. The brand sells a lot of Denali, AT4 and SLT trucks, and those trims are often where GM put push-to-start proximity keys first.

That creates the most common surprise in GMC key pricing: two trucks from the same model year, parked side by side, can need completely different keys. One has a flip key and a turn ignition. The other has a proximity fob and a start button. The fob is a more expensive part, it takes a longer procedure to program, and on some years it involves the body control module as well as the immobilizer.

Three things set the price of any GMC key:

1. The key type — transponder, flip or remote-head, or proximity smart key.
2. Whether a working key exists — adding a key is a short procedure; replacing every lost key is a longer security routine.
3. The electrical architecture — older GM security, the mid-generation systems most GMC trucks on the road use today, or the newest architecture that can require online authorization.

Everything else — the blade cut, the remote pairing, the trip — is a smaller variable on top of those three.

GMC Key Replacement Cost by Model and Key Type

The table below uses the same price bands we quote across our GMC and GM truck work. Years are approximate and trim-dependent; confirm your vehicle from its VIN before assuming a band.

GMC model and era	Most common key	Add a key (one working key present)	All keys lost
Sierra 1500 / HD, older generations	Cut transponder key or remote-head key	$120–$250	Quote required after diagnosis
Sierra 1500 / HD, mid-2010s base and SLE trims	Flip key with remote	$150–$300	Quote required after diagnosis
Sierra Denali, AT4 and upper trims, push-to-start	Proximity smart key	$250–$450	$350–$650+
Yukon / Yukon XL / Yukon Denali, push-to-start years	Proximity smart key	$250–$450	$350–$650+
Acadia, turn-key base trims	Flip key with remote	$150–$300	Quote required after diagnosis
Acadia and Terrain, push-to-start trims	Proximity smart key	$250–$450	$350–$650+
Terrain, base trims with a flip key	Flip key with remote	$150–$300	Quote required after diagnosis
Canyon, earlier mid-size generation	Flip key or transponder key	$120–$300	Quote required after diagnosis
Canyon, newest generation with push-to-start	Proximity smart key	$250–$450	$350–$650+
Savana van, fleet and work trims	Transponder or remote-head key	$120–$250	Quote required after diagnosis
Newest GMC architecture, including the electric Hummer	Proximity or digital key	Quote required after diagnosis	Quote required after diagnosis

Two notes on reading that table. First, "quote required after diagnosis" does not mean expensive — it means the price depends on details we cannot know without the VIN and, often, a look at the vehicle. An all-keys-lost Savana is frequently in the same neighborhood as an add-key job. Second, a second key cut and programmed in the same visit is an incremental charge on top of the first, because the programming session is already open. We explain that in the spare key section below.

Sierra: The Truck Where Trim Decides the Price

The Sierra is the GMC we program most often, and it is where the trim question matters most. Work trucks and many SLE trucks run a flip key or a remote-head key with a conventional turn ignition. Denali and AT4 trucks, and a growing share of SLT trucks, run a proximity fob and a start button.

For a turn-key Sierra, the job is straightforward: cut a blade to the truck's code, program the transponder to the immobilizer, and pair the remote functions. With a working key present that falls in the $150–$300 range for a flip key.

For a push-to-start Sierra, the fob has to be registered to the passive entry and start system, which is a longer routine. Adding a fob with a working one present runs $250–$450. When every fob is gone, the truck has to be put through a security learn procedure with built-in wait periods, which is why the all-keys-lost band starts at $350 and climbs with the year.

Newer Sierras sit on GM's most recent electrical architecture. If yours does, see our guide to GM Global B key programming on 2020-and-newer vehicles and the Silverado–Sierra breakdown in Chevrolet Silverado and GMC Sierra module and key programming. On some of those trucks a key procedure also touches the body control module, and a module that needs recoding adds its own line to the invoice.

Yukon and Yukon XL: Almost Always a Proximity Key

Most Yukons on the road in Tarrant County today are push-to-start. That puts nearly every Yukon key job in the proximity bands: $250–$450 to add a fob, $350–$650 or more when all fobs are lost. Denali trucks sit at the upper end of those bands more often than base trucks, mainly because of later model years and the extra features the fob controls.

The most common Yukon call we get is not a lost key at all. It is a family with one working fob and a second that has gone missing or quit after water exposure. That is an add-key job, and it is the cheapest point in the Yukon's key life to get a spare made.

Acadia and Terrain: Crossovers With Two Key Systems

The Acadia and the Terrain are sold in both configurations. Base trims often carry a flip key; upper trims carry a proximity fob. The price follows the key: $150–$300 for a flip key added to a truck with a working key, $250–$450 for a proximity fob added the same way.

The all-keys-lost case on these crossovers is where the VIN matters most, because the procedure differs between the older and newer architectures GM used across the generations. Some are a single visit with a standard wait period; others need extra steps. We quote them after reading the VIN rather than guessing from the model name.

Canyon: The Mid-Size Split

The earlier mid-size Canyon generation typically uses a flip key or a cut transponder key, and a spare falls in the $120–$300 range depending on which. The newest Canyon moved to push-to-start, which moves it into the proximity bands. If you are pricing a key for a Canyon, the model year is the first thing to check; a truck on either side of that generational line lands in a different band.

Savana: The Work Van Most Fleets Forget About

The Savana has carried a traditional transponder or remote-head key for a long time, which keeps its key cost in the $120–$250 range for most add-key jobs. Where Savanas get expensive is when a fleet loses track of keys and a single van needs every key replaced with no spare on hand. That is still usually a single visit, but it is an all-keys-lost job and gets quoted as one.

If you run several GMC or GM work vehicles, it is worth making a spare for each while one key still works. The cost difference between an add-key visit and an all-keys-lost visit, multiplied across a fleet, is significant.

What Changes the Price Inside Each Band

Once the key type and the working-key question set the band, these factors move the price up or down within it:

• Model year inside a generation. Later years in a generation sometimes carry updated security software that adds steps to the procedure.
• Trim features on the fob. Remote start, power liftgate and memory seat functions all live in the fob and are paired during programming.
• Blade type. A high-security laser-cut blade takes longer to cut than a standard edge-cut blade.
• Time of day. After-hours and weekend emergency calls carry a higher service fee than a scheduled daytime visit.
• Distance. A Fort Worth or Haltom City address is a shorter trip than an outlying county address.
• Module involvement. If the body control module has to be recoded or replaced as part of the key job, that is priced separately.
• Key source. We supply keys matched to the vehicle. A customer-supplied online fob can work, but only if it is the correct part and has never been locked to another vehicle; many are not, and a failed fob still uses programming time.

Spare GMC Key Versus All Keys Lost

The single biggest price driver in GMC keys is whether you still have one that works.

With a working key present, most GMC vehicles support an add-key procedure. The existing key authorizes the session, the new key is learned, and the job is short. That is why the add-key column in the table is the lower one on every row.

With every key lost, the immobilizer or passive-start system has to be put into a learn routine without a working key to vouch for the new one. Many GM procedures include deliberate security wait periods — the system counts down before it will accept a new key — and the newest architecture can require online authorization tied to a registered professional account. None of that is the locksmith padding the job; it is how GM built the security.

If you are down to one GMC key, the least expensive thing you can do is have a spare made now. Our spare key cost by key type guide breaks that down across every key style, and our GM and Chevy all-keys-lost programming guide covers what happens when the last key is gone.

When a GMC Key Problem Is Not a Key Problem

A good share of the "my GMC key stopped working" calls we get turn out to involve something other than the key.

• Key fob battery. A weak coin cell reduces range and can make a push-to-start truck say it does not detect the key. Replace the battery first; it is the cheapest test there is.
• Body control module faults. When the lock, unlock and remote start functions quit together and a new battery does not help, the module that receives the fob signal may be the problem rather than the fob. See BCM programming near me for how that is diagnosed.
• Ignition switch or cylinder wear. On older turn-key GMC trucks, a key that will not turn, or turns without the truck responding, is often worn ignition parts rather than a bad key. Our Chevrolet and GMC ignition switch repair guide covers those symptoms.
• Passlock or VATS on older GM trucks. Some older GM vehicles use security systems that fail in ways that look like a key problem. See our GM VATS and Passlock guide.

Diagnosing the real fault before cutting a key is part of the job. A key that would not have fixed the problem is money spent for nothing.

Dealer, Online Fob, or Mobile Locksmith

There are three common routes to a new GMC key.

The dealership can make any key GM builds, but usually needs the truck on its lot. For an all-keys-lost truck that means a tow before the key work even starts, and service department scheduling can add days.

An online fob looks inexpensive, but it still has to be cut and programmed, and a meaningful share of low-cost fobs are the wrong frequency, the wrong part number, or previously locked to another vehicle. When that happens the programming time is spent and the fob still does not work.

A mobile automotive locksmith comes to the truck, supplies a key matched to the VIN, cuts it, programs it, and confirms every function before leaving. For most GMC trucks, SUVs and vans, that is the fastest route and usually the least expensive. For a broader comparison, see dealership versus locksmith for car keys.

What to Have Ready When You Call

A GMC key quote is only as accurate as the information behind it. Before you call, have:

• The VIN, from the lower corner of the windshield or the driver door jamb sticker.
• The year, model and trim — "Sierra Denali" and "Sierra Pro" are different key conversations.
• Whether any working key exists, even a worn one.
• Whether the truck starts with a button or a turned key.
• The address where the vehicle is parked.

With those, we can give a quote that holds when we arrive. Our car key replacement service and smart key programming service pages describe the work itself, and the Chevrolet key page covers the platforms GMC shares with its sister brand.

A Note on Licensing and Honesty

In Texas, locksmith companies are licensed through the Department of Public Safety Private Security Program. Ask any locksmith for their license number before they touch your vehicle. We also recommend the Federal Trade Commission's consumer guidance on hiring a locksmith (ftc.gov), which describes the bait-and-switch pricing some operators use. A legitimate quote names the key type and the procedure; a vague "starting at" number that triples on arrival is the pattern to avoid. For more on spotting that, see how to avoid locksmith scams.

Frequently Asked Questions

How much does a GMC key replacement cost in Fort Worth?

As of September 2026, a mobile specialist in Fort Worth typically charges $120 to $250 for a cut and programmed GMC transponder key, $150 to $300 for a flip key with a remote, and $250 to $450 to add a push-to-start proximity fob when a working key still exists. When every key is gone on a smart-key GMC, expect $350 to $650 or more because the immobilizer has to be put into a learn procedure. The exact figure depends on model, year, trim and whether a working key is available.

Why do two GMC trucks from the same year cost different amounts?

Because GMC sells the same model with different key systems depending on trim. A base Sierra or Terrain can leave the factory with a flip key and a turn ignition while a Denali or upper trim of the same year uses a push-to-start proximity fob. The proximity key is a more expensive part and takes a longer programming procedure. The VIN, not the model year alone, is what tells a locksmith which key a specific vehicle needs.

Is it cheaper to add a spare GMC key than to replace a lost one?

Yes, and usually by a meaningful margin. When one working key is present, a second key can be added through the vehicle's normal add-key procedure. When every key is lost, the security system has to be reset or put into a longer learn routine, which takes more time and on some newer platforms requires online authorization. Cutting and programming a spare while you still have one working key is the least expensive time to do it.

Can a locksmith program a GMC key without going to the dealer?

For the large majority of GMC trucks, SUVs and vans on the road, yes. A mobile automotive locksmith with current GM programming equipment can cut the blade, program the transponder or proximity fob, and pair the remote functions at the vehicle. The newest GMC electrical architecture can require online security access for certain procedures, and an honest specialist will confirm that from the VIN before quoting rather than after arriving.

Do I need to bring every GMC key I have?

Bring every key you want to keep working. On many GM platforms the programming procedure can clear keys that are not present during the session, so a key left in a drawer at home can stop starting the vehicle afterward. Having all keys at the vehicle means each one can be confirmed or re-learned in the same visit instead of creating a second appointment.

How long does GMC key programming take?

Adding a key to a GMC with a working key present usually takes thirty to sixty minutes including blade cutting. All-keys-lost jobs run longer because of the security wait periods built into many GM procedures, and a truck that also needs body control module work can take a few hours. Most jobs are completed at the vehicle in a single mobile visit.

Does my GMC key price include the remote buttons?

On a flip key, remote-head key or proximity fob, the quoted price includes programming the lock, unlock, panic and remote start functions the key supports, because on those keys the remote and the immobilizer chip live in the same housing. A separate keyless entry remote on an older truck is programmed alongside the key and is usually a small incremental charge rather than a second full job.
