1999 Cadillac Deville Metal Key Replacement - Fast, Affordable & Professional

A guy in Cardiff-by-the-Sea called me on a Tuesday morning. He had a 1999 Cadillac DeVille sitting in his driveway that he could not lock up before heading to work because the key had finally decided it was done coming out of the ignition. He had been fighting it for a while, wiggling the shifter, rocking the steering wheel, pulling with two hands. That morning it just stopped cooperating entirely.

He told me a shop had already quoted him a full ignition cylinder replacement, new keys cut from scratch, the whole package.

I got there and pulled out my decoder. The cylinder was not seized, it was tired. Twenty-five years of daily turning had worn the wafers down unevenly. The park interlock mechanism was also dragging, not broken, just gummed up with old lubricant that had turned to a film of nothing. Between those two things the key had nowhere clean to seat at the off position.

I decoded the existing key cut, replaced the worn wafers, cleaned and freed up the interlock, and verified the key would go in and come out smooth through the full rotation, park, accessory, run, start, and back out again. That is the part a lot of people skip. They fix one thing and hand the key back. I cycle it a dozen times before I call it done.

He got his key back that morning. No tow, no waiting on parts, no week at a shop. And he paid a fraction of what the cylinder-replacement quote would have cost him.
