2007 Buick Lacrosse Transponder Key Replacement - Fast, Affordable & Professional
Got a call on a Wednesday from a dentist at his practice lot in Ventura, near Rincon Beach Park. His 2007 Buick LaCrosse wouldn't start. Patients booked all day, security light glowing solid on the dash, and "Starting Disabled" staring back at him from the DIC.
He'd already tried the usual. Turn the key, wait, try again. Nothing. Just that flat message and a dead starter circuit.
I drove out over his lunch break. Popped the B111 Lishi on the ignition to verify the wafers were reading the blade cuts correctly. Everything matched. The mechanical side was fine. Plugged into the OBD-II port under the dash and pulled up the BCM on the Tech2 emulator. The PK3 theft-deterrent module had thrown a false lockout, a known issue on these W-body GMs where the Passlock sensor resistance drifts out of range and the BCM just shuts everything down.
Ran the security relearn procedure through the BCM. There's a mandatory 10-minute timer built into the process, so I cleaned the Passlock connector pins while it counted down. Once the relearn completed, the transponder re-synced on the first crank. All three buttons on the 5928820 remote tested good at the doors.
He walked out after his 1:00 patient to a running car. The whole thing took less time than a crown prep. A dealer would have meant a tow, a wait for an open bay, and a chunk of his week gone.
