2004 Buick Rendezvous
Key Replacement - Save vs Dealer in San Diego

2004 Buick Rendezvous Transponder Key Replacement - Fast, Affordable & Professional

A guy out near Harbison Canyon reached me on a Saturday afternoon. He had been to a swap meet earlier, came back to his 2004 Rendezvous, and his only key was gone. Not in his pocket, not on the ground near the driver door. Gone.

He had already called the dealer. Monday appointment, parts potentially on order, timeline measured in days. He found me through a search and figured he had nothing to lose.

I drove out to him in Alpine. The Rendezvous was sitting in a gravel lot, locked, one key to its name and that key was somewhere on a swap meet table by now. All-keys-lost on this generation of GM vehicle means the immobilizer has no registered key to reference, so I connected my equipment to the OBD port, cleared the key memory, and enrolled a fresh transponder key cut to his vehicle on site.

The part that takes the longest on an all-keys-lost job like this is not the cutting or the programming. It is the timed security relearn cycle built into the system. You just have to let it run. I explained that to him while we waited. He appreciated knowing what was actually happening instead of just watching me stare at a laptop.

Key turned, engine started, drove it in circles around the lot to confirm. He saved a good chunk compared to what the dealer quoted and did not lose Monday to an appointment.
