1999 Buick Lesabre Remote Replacement - Fast, Affordable & Professional
A soccer league coach at the community center lot near Simi Hills Golf Course on a Saturday told me he'd already been burned. Another locksmith charged him full price for a 1999 Buick Lesabre key that never programmed correctly. The car would crank but the theft-deterrent system killed fuel injection after two seconds. The other tech told him the BCM was dead and left.
The BCM wasn't dead. It had a locksmith problem, not a module problem. GM's theft-deterrent system requires a specific security access procedure with a timed window. If you don't complete the relearn correctly, the module rejects the key and logs a fault. The previous tech hadn't gotten past the security access step.
I used my B111 Lishi to verify the mechanical cut, then connected through OBD with my IM608. I cleared the faulted key entry, properly entered the BCM security access window, and ran a clean PK3 relearn. His smart fob, FCC ID KOBUT1BT, had all 4 buttons working plus a clean start with no fuel cutoff. I showed him the confirmation on my screen.
He paid me 95. A dealer charges 200 for the same work. The difference on Buick is that the theft-deterrent system is particular, and a locksmith who's never touched one will fail.
