Key Replacement - Save vs Dealer in San Diego

2011 Buick Enclave Transponder Key Replacement - Fast, Affordable & Professional

I got a call out to the Peutz Valley area, near the boarding kennel lot off the main road through Alpine. The owner of a 2011 Buick Enclave had found me on YouTube. He'd been watching forum threads go nowhere and finally just searched for someone doing actual GM key work on video. He recognized the diagnostic setup from one of my walkthroughs and saved my number before he even had a problem. When the intermittent failures started, he already knew who to call.

The symptom was the kind that makes people doubt themselves. The key would start the car fine three times in a row, then nothing on the fourth. No crank, dash warning, and the engine just sat there. He'd wait a minute, try again, and it would fire right up. That pattern almost always points to the transponder side of things, not the ignition cylinder and not the starter.

I pulled up, set up stable voltage at the battery, and ran the programming sequence with my diagnostic equipment. The transponder chip in his key had not been fully enrolled, most likely from a prior attempt at a shop that didn't finish the job clean. I cleared the old partial registration, enrolled his replacement key properly, and ran the start cycle five times back to back.

He mentioned the dealer had told him to expect a wait and a bill that made him wince. He drove away that day from the kennel lot with a key that worked every single time, for a fraction of what they wanted.

The same person you watch on the video is the same person who shows up at your car.
