2007 Buick Lucerne Transponder Key Replacement - Fast, Affordable & Professional

Out in Harbison Canyon, the calls I get tend to come from people who've already tried the obvious. This one was no different.

A guy had a spare key made at a hardware store kiosk months back. The blade was cut fine, turned the ignition no problem. He thought he was set. Then his original key got damaged and he grabbed the spare. Car cranked, fired for about a second, and died. Every time. He assumed the starter was going or something in the fuel system. He'd already talked to a mechanic friend who said it might be the fuel pump.

I drove out to him in Harbison Canyon and watched him try it once. That one-second start and immediate stall is a pretty specific thing. That's the immobilizer doing its job. The hardware store key had the right blade cut, but nobody had programmed the transponder chip. It was a blank chip in a cut key. Looked right, acted wrong.

I had the right key blank in the van, programmed it on site to his vehicle, and let him try it himself once it was done. It caught and idled like nothing had ever been wrong.

He'd been nursing that spare for two days thinking the car had a mechanical problem. The fix was the transponder, done in his driveway, no tow, no dealer waiting room.
