Key Replacement - Save vs Dealer in San Diego

2003 Buick Century Remote Replacement - Fast, Affordable & Professional

Fletcher Hills sits up in the hills east of El Cajon proper, the kind of neighborhood where streets dead-end against canyon brush and there's no such thing as a quick flatbed recovery.

A guy called me about his 2003 Century parked at the bottom of one of those streets. He'd lost his only fob and his remote had stopped responding weeks earlier. He'd been meaning to deal with it. Then the battery in his key fob went completely dead, and when he finally went to use the car, nothing worked. The dealer told him to tow it in. He looked down that narrow canyon street and called me instead.

I pulled up at the top of the street with everything I needed already in the van. Replacement fob matched to the factory FCC ID on his original, fresh CR2032, and my programming equipment.

The Century's fob programming runs through the body control module via the OBD port. I connected, ran the sequence, and registered the new remote. Then I tested every button standing right next to the car: lock, unlock, trunk. All three working.

He mentioned the dealer had quoted him a multi-day turnaround just to get the part in stock. He saved a good chunk and his car never left that street under anything other than its own power.

The job itself was about 25 minutes. Most of that was the programming sequence and button verification.
