Prices vary by exact model, year, and whether you have a working spare. Mileage adjustments apply outside Auburn — quoted upfront. Call (253) 796-8550 for an exact quote on your specific GMC.
Step 1: Call us with your VIN. Year, make, and model help, but the VIN tells us exactly what key technology your specific GMC uses and whether we can handle it on-site. We verify upfront so you don't waste a service call.
Step 2: Flat-rate quote. Based on your VIN and key situation, we quote a flat-rate price over the phone. The number you hear is the number you pay.
Step 3: Mobile service to your location. We come to wherever your GMC is parked — your driveway, work parking lot, the side of the road. No towing required.
Step 4: ID verification. We verify proof of ownership (registration, title, or insurance + photo ID). This is required for everyone — it's how we protect your vehicle from theft via fake locksmith calls.
Step 5: Cut and program the key. Most GMC keys take 20-60 minutes. All-keys-lost programming can take longer due to security timer delays built into the vehicle.
Step 6: Test and go. We confirm everything works — door locks, ignition/start, remote functions if applicable — then you drive away with a fully working key.
Yes — for the vast majority of GMC models from 1999 to current. We carry blanks, transponders, remote heads, and smart proximity keys for Sierra, Sierra HD, Yukon, Yukon XL, Acadia, Terrain, Canyon, Savana, and Hummer EV. Some 2023+ Hummer EV and specialty Denali configurations require VIN verification — we check upfront.
Older Sierra transponder keys: $135-$245. Newer Sierra smart proximity keys (Denali, AT4): $285-$485. Pricing varies by year/trim. All quotes flat-rate upfront. Even when we handle GMCs on-site, we're usually 40-60% less than dealer pricing plus you skip the tow.
Yes — for most GMC models we can program all-keys-lost replacements on-site via the OBD-II port. Most GM/GMC vehicles have 10-30 minute security timer delays for all-keys-lost programming, which is normal.
Standard GMC transponder keys: 20-30 minutes. GMC smart proximity keys: 30-60 minutes. All-keys-lost programming: 45-90 minutes due to GM's security timer.
Yes. Yukon Denali, Sierra Denali, Acadia, and other GMC models with push-to-start and remote start smart keys are routine for us. We cut the emergency blade and program both the proximity functions and remote start capability.
Mechanically and electronically, GMC and Chevy use the same GM key systems — but the physical key blanks and fob housings are GMC-branded. We carry both and the programming process is identical. If you have a GMC Sierra and a Chevy Silverado in the same family, they use the same underlying technology but each needs its own brand-specific key.
