2012 Chevrolet Traverse Transponder Key Replacement - Fast, Affordable & Professional

Out near the Encanto Border side of Lemon Grove, a woman flagged me down in the Target parking lot on a weekday afternoon.

She had one key for her 2012 Chevrolet Traverse and she'd already bent the blade trying to force it into the door lock on a hot day. The key still worked in the ignition, but she wasn't sure for how long, and she wanted a spare before it became a bigger problem.

She'd called the dealer first. They quoted her an appointment slot about a week out and told her the key would need to be ordered. She asked if a locksmith could do it and the service advisor said something vague about "GM-specific equipment." Which is true for all-keys-lost. Not true for what she needed.

She had one working key. That's the part that changes everything on this vehicle.

I pulled up behind the Traverse and she watched me cut a new key blank to her existing key, then walked her through what I was doing at the ignition. The onboard relearn sequence on this generation is not complicated when you have a working key to start from. Ignition on, ignition off, specific timing, and the module accepts the new transponder. I verified it started cleanly on its own, no hesitation, no warning lights on the dash.

She made it back inside before her lunch break ended. The dealer's appointment was still sitting on the calendar. She cancelled it on the way back to her desk.
