Key Replacement - Save vs Dealer in San Diego

1998 Cadillac Eldorado Remote Replacement - Fast, Affordable & Professional

I got a call from someone in Old Town National City on a weekday afternoon. His 1998 Eldorado was sitting in the driveway and the fob had just stopped working completely. No response on any button. He had already called around and one place told him the car would need to go to the dealer.

When I got there the fob case had a small crack along the seam, the kind that happens when someone pries it open with a screwdriver instead of a trim tool. The CR2032 inside was fine voltage-wise but it was sitting at an angle and one contact was slightly bent away from the battery face. The remote was getting intermittent contact at best.

I re-tensioned the contact, seated the battery correctly, pressed the case back together, and then ran the onboard add-a-key sequence right at the car. No scan tool, no OBD port, no tow. The whole thing took under twenty minutes including walking every button and confirming trunk release worked from the end of the driveway.

He had mentioned the dealer as a possibility mostly out of habit. I didn't make a big deal of it. He kept the working fob, paid a fraction of what the dealer would have charged, and the car never left the driveway.
