2010 GMC Canyon Transponder Key Replacement - Fast, Affordable & Professional

I got a call from someone parked along Cedros Avenue in Solana Beach, right in the middle of the Cedros Design District. She had walked the shops, come back to her 2010 GMC Canyon, and the only key she had left was a copy she'd had cut at a hardware store after losing her original a few months back.

The copy had been working fine, she said. Then one morning it just stopped starting the truck. Engine would crank, catch for a second, and die. Over and over.

When she told me about the copy key, I already had a pretty good idea of what happened. Some transponder blanks program cleanly and hold their signal for a long time. Others drift, especially cheaper aftermarket blanks, and the immobilizer stops recognizing the chip. The blade was fine. The cut was fine. The chip had become unreliable enough that the vehicle security system rejected it.

I pulled up to Cedros, popped the hood of my van, and got to work. Cut a new key to her vehicle, programmed the transponder chip on site, and tested it through several start cycles before I called it done.

She mentioned in passing that a GMC dealer had already told her it might be a "bigger electrical issue" based on her description over the phone. It wasn't. It was exactly what it looked like: a transponder that had stopped doing its job. Mobile, done on site, for a fraction of what the dealer route would have cost even for a diagnostic appointment alone.
