GMC Sierra Automotive Locksmith

The GMC Sierra was produced 1989–2027. It is a current pickup truck, so parts availability is generally good and the security procedures are the current-generation ones.

The Sierra’s 1989–2027 run crosses three key generations: model years 1989–1995 predate transponder immobilizers in the US market, so a replacement there is usually a cutting job rather than a programming one; 1996–2006 sit in the transponder era, where the key carries a chip and often a remote head, so the work is cutting and programming together; and 2007–2027 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. Which one applies to a particular Sierra is decided by its model year and trim, not by the nameplate, 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 Sierra 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.
