GMC Key Replacement in Lafayette, Indiana
Sierra in the yard, Terrain in the garage, or a Savana van on a route — our mobile locksmith comes to your GMC anywhere in Lafayette or West Lafayette and cuts and programs the key on-site.
GMC Key Systems Through the Years
GMC runs on General Motors security, and knowing the generation tells you what your key needs. Many 1996–2007 models use Passlock, which reads the ignition lock cylinder instead of a chip — the usual suspect when a security light flashes and the engine dies right after starting. Alongside and after that came transponder (chip) keys, then flip keys with built-in remotes on trucks and SUVs through the 2010s, and today's push-to-start proximity fobs on the Sierra, Yukon, Acadia, and Terrain. Because the Sierra is the Silverado's twin, GMC keys are well-supported parts we nearly always have in stock on the van.
A lot of GMCs around Tippecanoe County are working vehicles — contractor Sierras, delivery Savanas, family Yukons pulling campers. We come to the truck wherever it earns its living, and program the key without the vehicle moving an inch.

Frequently Asked Questions
My GMC cranks and then dies, and the security light is flashing. Is that the key?
On many 1996–2007 GMCs that's the Passlock system — GM's early anti-theft, which reads the lock cylinder rather than a chip in the key. Crank-then-stall with a flashing security light means the system isn't seeing a valid signal, which can be an unprogrammed key, a worn cylinder, or a failed Passlock sensor. Our locksmith can diagnose which it is at your location; sometimes a relearn cycle fixes it, and when the sensor is bad we can service the cylinder itself.
Is a GMC Sierra key the same as a Chevy Silverado key?
Mechanically, yes — the Sierra and Silverado are twins built on the same platform, and their keys, fobs, and programming procedures match year for year. That's good news: parts are plentiful and we almost always have the right key or fob on the van. If you're researching your truck, our Silverado key replacement page applies to the same-year Sierra nearly line for line.
Can you program a used GMC smart fob I bought online?
Honest answer: usually not, if it's used. GM locks push-to-start smart fobs to the first vehicle they're programmed to, so a secondhand fob from a salvage Yukon typically can't be paired to yours. A new aftermarket or OEM fob with the right FCC ID programs fine, and we carry common ones on the van. Text us your year and model before buying and we'll save you a wasted purchase.
We run a few GMC work trucks and vans. Can you make spare keys for the whole fleet?
Yes, and it's cheaper done proactively than one emergency at a time. We can come to your shop or yard in Lafayette, cut and program spares for every Sierra, Savana, and Canyon in one visit, and keep a record of what each truck takes. One lost-key morning with a crew standing around costs more than a full set of spares.
All keys to my Yukon are gone. Does it have to go to the dealership?
No. With your ID and proof of ownership we can generate a new key from the VIN or the door lock and program it right where the Yukon is parked — including push-to-start models, which dealers usually insist on towing in. Same process for the Acadia, Terrain, and Sierra. You keep the tow money.
How much is a GMC key or fob compared to the dealer?
It ranges widely: a basic transponder key for an older Sierra costs far less than a Denali-trim proximity fob. Whatever the key type, we're typically well under GMC dealer pricing and there's no tow or multi-day wait. Call (567) 227-5397 with your year and model for an exact number, or see our car key cost guide.
