GMC Sierra Key Replacement
Need a new or spare key for your GMC Sierra? LockFox comes to you anywhere in Palm Beach or Broward County and cuts and programs replacement keys, remotes and smart keys at the vehicle in many cases — even when no working key is left.
Check your GMC Sierra version
The Sierra name covers several versions. For 2019, GMC describes a redesigned Sierra 1500, while its parts catalogue separately lists Sierra 1500 Limited, 2500 HD and 3500 HD. A single generation label for that year does not identify every Sierra, and it does not establish key compatibility.
Vehicle identification: GMC 2019 Sierra brochure; GM catalogue: vehicle names and years. These sources do not establish key compatibility.
Which key does your GMC Sierra use?
The right key depends on the model year and trim. Most vehicles fall into one of these types:
- Metal key — a plain blade with no chip, common on older vehicles.
- Transponder (chip) key — the engine only starts when the chip is programmed to the car.
- Remote-head or flip key — lock/unlock buttons built into the key; the blade is cut, while the chip and remote may need programming.
- Proximity smart key — stays in your pocket; used with push-button start.
Is your Sierra a 1500, 1500 Limited, 2500 HD or 3500 HD? Include the model year, trim if known, and whether it uses a turn-key ignition or a start button when you call for an estimate. If you are unsure of the version, have the VIN ready for the call. Tell us whether any key still works so we can check service availability. See also car key replacement and key fob programming.

What to have ready when you call or text

- The VIN if you can get it: it’s on the registration and insurance card, and visible through the windshield on the driver’s side of the dashboard.
- How many working keys you still have (none, one, or two). A spare made from a working key is usually simpler than an all-keys-lost job.
- Proof of ownership: a photo ID plus the registration or title. We verify ownership before we cut or program any key.

Common questions
Can you replace a GMC Sierra key with no working key?
In many cases, yes. An all-keys-lost job on a Sierra depends on the model year and key system. Call or text your year and VIN and we will confirm before we dispatch.
How do I know which key my Sierra uses?
Look at the key: a plain metal blade, a blade with a thick plastic head (often a chip key), a key with buttons, or a push-to-start fob. The model year, start system and a photo of an existing key help identify the key type. Compatibility may also depend on the trim, VIN and the key itself; confirm it before buying a replacement.
Is a spare Sierra key cheaper than replacing a lost one?
Usually. Copying a working key is typically simpler than an all-keys-lost job. If you are down to one key, a spare is worth getting now.
