2011 Buick Lucerne Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy sitting in a medical office lot near La Cumbre Plaza in Santa Barbara. Post-surgery, on crutches, and his 2011 Buick Lucerne would not start. He had one transponder key left and the security light was just sitting there, solid, on the dash. No crank, no nothing.

His wife was at work across town. The dealer told him they could get him in next week, maybe, and he would need a tow. He had a follow-up appointment in two days and no second car.

I got to him that morning. The Lucerne uses a PK3+ transponder system with the B111-PT key blank and a Megamos-type ID 13 chip embedded in the key head. I decoded the HU100 keyway with my Lishi, cut a new key on site, then connected my IM608 to the OBD-II port and talked to the body control module to register the new transponder. The BCM on these is the W-body style unit, and the security relearn went clean. No ten-minute wait loops, no drama.

Cut, programmed, tested. He turned the key, the security light flashed and went out, and the 3800 V6 fired right up. He just nodded, like the car had finally stopped arguing with him.

He stayed in the building for most of it. Never had to call his wife, never had to arrange a tow, never had to reschedule anything.
