Cadillac Key Fob Replacement and Programming in PGA Village

A PGA Village homeowner called about a Cadillac whose remote had stopped locking, unlocking and starting the car. The buttons still had voltage, but the vehicle no longer responded — a symptom that points to a de-authenticated or physically failing fob, not a dead battery. We arrived with the correct blade blank and a fresh OEM-equivalent proximity fob for that model year.

Modern Cadillac smart keys are more than remotes. Each one carries an encrypted rolling code that the vehicle's body control module recognizes as authorized. When a fob is replaced, the vehicle has to be told to trust the new one and — in many cases — the old fob has to be de-authorized in the same session, so a lost fob cannot be used to steal the car later.

In the driveway, we connected to the vehicle's OBD-II port with a manufacturer-capable programmer, entered the security session for the platform, and paired the new fob to the vehicle. Push-to-start was tested, remote lock and unlock verified, panic and trunk buttons confirmed, and the passive-entry range checked from three sides of the vehicle.

Because the homeowner still had one working fob, we did a two-fob session — new fob added, old fob retained as a spare. On all-keys-lost jobs the process is longer (the vehicle typically has to go through a security time-out first), but response and pricing are still far below what a dealer tow-and-program job would run.

For a PGA Village address, dealer trips mean an hour each way, plus tow costs if the vehicle is not driveable. Mobile automotive locksmith work removes that entire chain — we come to the driveway, we do the whole job in the driveway, and the customer keeps their day.
