Key Replacement - Save vs Dealer in Ventura County

2002 Buick Century Remote Replacement - Fast, Affordable & Professional

A guy at the Ventura Harbor Village parking lot near the swap meet flagged me down one evening. His 2002 Buick Century wouldn't start. He'd turn the key, the engine would crank for a second, then die. The "SECURITY" light on the dash stayed solid, not flashing. Classic Passlock II lockout.

He'd already called around. Two locksmiths turned him down because they heard "Buick" and assumed transponder. A dealer quoted him days, not hours, and wanted the car towed in.

I plugged into the OBD-II port under the dash and pulled the Body Control Module, GM part number on his was a 09378095. The Passlock relearn procedure on these W-body cars has a mandatory 10-minute wait cycle, three times in a row. Thirty minutes of the car just sitting there in "learn" mode. Not glamorous work. We talked about the records he'd found at the swap that day while the timer ran.

While the BCM did its thing, I programmed his replacement L2C0007T remote. Lock, unlock, trunk. All three buttons confirmed from about 30 feet out.

After the third 10-minute cycle, I turned the key and the Century fired right up. The "SECURITY" light went off. He just sat there for a second like he didn't trust it.

The whole job happened in that parking lot. No tow, no appointment, for a fraction of what the dealer wanted just to look at it.
