GMC models we make keys for include: Sierra 1500, Sierra 2500HD, Yukon, Yukon XL, Acadia, Terrain, Canyon, Savana — and more. Tell us the year and model and we confirm.

GMC keys we make

  • Transponder keys — chipped turn keys on older Sierra, Yukon, Envoy and Savana models, often paired with a separate remote.
  • Flip keys — fold-out blade with built-in remote on many turn-key Sierra, Terrain and Canyon models.
  • Smart keys (push-to-start) — on many newer Sierra, Yukon, Acadia and Terrain trims, including Denali and AT4, with the emergency blade inside.
  • Separate remotes — keyless entry and remote start fobs programmed to vehicles that start with a regular key.

Common GMC key calls

Sierra key lost on the job. A Sierra or Sierra HD tends to be somebody's work truck, and when its one key goes missing the day stops. We cut and program a new key at the jobsite or yard so the truck is back to work without a tow.

Remote start stopped working. A Yukon or Sierra remote that no longer starts the engine or locks the doors may just need a battery, or it may have dropped out of the vehicle's memory. We test it, then program it or replace it.

Only one Yukon key for the family. Full-size SUVs get shared between drivers, and the second key tends to go missing. A spare made while one still works is quicker and costs less than an all-keys-lost job.

Why not the GMC dealer?

With no working key, a GMC dealer needs the vehicle on site — and towing a Yukon XL or a Sierra HD costs more than towing a sedan — plus an appointment and sometimes a wait for the key to be ordered. We bring GM key blanks, a cutting machine and programming equipment to you, and for most models finish in one visit, often for about half the dealer's price.

GMC Key FAQ

Why does programming a key take so long on my older Sierra or Yukon?

Many older GM trucks and SUVs use a timed security relearn when a key is added with no working key present — the truck makes you wait through a set security period, often about half an hour, before it accepts the new key. It's normal, and we handle it at your vehicle.

Can you program a key for a newer GMC?

For many models, yes, including many Sierra, Yukon, Acadia and Terrain years with push-button start. Some of the newest GMC models use a newer GM electronic platform where key programming may be limited to the dealer. We check your year and model and tell you upfront if yours is one of them.

My Savana has a plain key and a separate remote. Can you replace both?

Yes, for most Savana years. We cut and program the chipped key and program a new remote to the van, so both lock and start work again.

How much is a GMC key?

Car keys start at $119. A chipped key for a Savana or older Sierra usually costs less than a Yukon Denali smart key. Call with your year, model and trim and we'll give you the price before a technician is sent.
