GMC Terrain keys and immobilizer
The GMC Terrain was produced 2009–2027. It is a current SUV or crossover, so parts availability is generally good and the security procedures are the current-generation ones.
Across its 2009–2027 run, the Terrain sits in one key generation: 2009–2027 are the proximity era, where push-button start and smart keys spread across trims — and where all-keys-lost is a security operation that can involve a timed wait or erasing keys the car already accepts. The exact model year and trim still decide the parts, so have the year ready when you call.
On a vehicle this recent, most "key" faults turn out to be the fob battery. Before assuming a failed key, try the vehicle's backup start position — usually holding the fob against the start button or a marked point on the steering column — and see whether it starts.
Eligibility for the GMC Terrain is confirmed against the exact model year and trim before a job is treated as scheduled, and proof of identity and vehicle ownership or written authorization is required before any key is originated or programmed.
