2014 Chevrolet Traverse Transponder Key Replacement - Fast, Affordable & Professional

I got a call on a Tuesday afternoon from a woman parked near Downtown La Mesa. She had her 2014 Traverse, her kids, and one key that had just stopped working. Not lost, not broken in the lock. It just wouldn't turn the engine over. The car would crank, almost catch, then die. She'd already tried twice and was starting to panic.

When I pulled up, I had her try the key one more time while I watched. It cranked and immediately stalled. That pattern points to the vehicle security system not recognizing the key, whether that's a chip that's gone bad, a key that somehow lost its programming, or an antenna issue at the ignition cylinder. It's a specific failure mode and I've seen it more than a few times on this generation.

I connected my programmer to the OBD port, pulled up the Traverse, and confirmed the key wasn't being read. The transponder chip in her key had failed. She only had the one key, so we were in all-keys-lost territory.

I cut a new key blade to her vehicle on site, programmed the transponder, and walked through the security relearn. The whole job took about 45 minutes in that parking lot off La Mesa Boulevard.

She mentioned the dealer had been her first call. They told her to have it towed in, said they'd need to order the key, and couldn't get her in until later in the week. She was looking at a tow bill, a rental, and days without the car. Instead she made it home that afternoon.
