2005 Buick Lacrosse Transponder Key Replacement - Fast, Affordable & Professional
Got a call from a woman out near Lake Casitas Recreation Area in Ventura. She had a 2005 Buick LaCrosse CX parked at the lot and only one key to her name, and that one had a cracked bow with the transponder pellet barely hanging in there. Every few tries the THEFT SYSTEM light would flash and the car would crank but refuse to start. Then it would work. Then it wouldn't. She had been living with it for weeks.
I pulled up and checked her original key first. The plastic shell around the PK3 chip was split right down the spine. The chip was making contact sometimes, losing it other times. Classic intermittent read failure on the Passlock module.
Cut a fresh 5928820 blank on my HPC machine, then connected my programmer to the OBD-II port and ran the PK3 security access procedure through the BCM. The 2005 LaCrosse needs a ten-minute security relearn timer to cycle before it accepts a new transponder ID. Sat there with her watching the countdown on my screen. Once it cleared, the new key fired the 3.8L on the first turn.
Programmed a second spare while I was there so she would never be down to one key again. She mentioned the dealer quoted her multiple days because they had to order the blank and schedule around other work. She was back on the road in about 40 minutes total.

“Fast, affordable, and a great price. Marco did an amazing job and made a key for our Nissan Kicks quickly and professionally. Everything worked perfectly.”
“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”
