Treasure Coast Locksmith provides GMC key replacement services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. GMC uses the same PassKey III and PassLock immobilizer as Chevrolet (both GM brands). Autel IM608 Pro handles all GMC programming via OBDII. Typical $195-$365 versus $350-$525 at GMC dealer.
All models including Sierra, Yukon, and Hummer EV.
GMC is GM's truck and SUV brand, sharing platforms with Chevrolet. Sierra is the upscale version of Silverado, Yukon matches Tahoe, Acadia sits alongside Traverse. All GMC models use the same PassKey III (2005-2015) and modern PassLock (2016+) immobilizer as their Chevy platform-mates.
Our Autel IM608 Pro handles GMC programming identically to Chevy - same equipment, same procedures, same PIN database. The main differences are cosmetic (GMC trim levels and luxury features) rather than technical.
Treasure Coast Locksmith programs every GMC model from 1998 through 2026 including the new Hummer EV. Typical job runs 30-75 minutes onsite.

GMC and Chevrolet shared programming
GMC uses GM's PassKey III immobilizer (2005-2015) and PassLock (2016+) identically to Chevrolet. Programming procedures, equipment requirements, and PIN lookup database are shared. Our Autel IM608 Pro handles GMC and Chevy interchangeably with automatic brand detection from VIN.
For 2019+ GMC models, PIN code authorization from VIN is required before programming. Autel retrieves PIN automatically. Smart key programming (Sierra Denali 2015+, Yukon 2015+, Acadia 2017+) includes chip and fob in the same session.
GMC-specific quirks: Sierra AT4 and Denali Ultimate trims use same PassLock as base Sierra. Yukon Denali uses smart key variant different from Tahoe Premier (minor differences). Hummer EV (2022+) uses enhanced PassLock with EV extensions.
Sierra 1500 and 2500/3500 HD share programming with variations in smart key fob style.
