2022 Cadillac XT4 Smart Key Replacement - Fast, Affordable & Professional

Down near Moonlight Beach on a Tuesday afternoon, a woman called me from the parking lot off B Street. She had both of her 2022 XT4 fobs with her, which is better than most people. The problem was that neither one had been working reliably for about a week, and that morning the vehicle threw a key-not-detected warning and wouldn't start on the first press. She tried again and it caught. She drove straight to the beach, parked, and then didn't trust herself to turn the car off.

She was sitting in it, running, when I pulled up.

I checked both fobs. One had the original battery, which read low on my tester. The other had a CR2032 she'd swapped in herself maybe two months prior, but the contact inside had a slight give to it from being pried open with something too wide. Neither fob was dead. Both were just underperforming in different ways.

Fresh cells in both, contacts cleaned and checked, and I walked through every function on each one before I called it done. Passive entry on both front handles, the liftgate, the lock and unlock sweep, and verified the vehicle security system was seeing both fobs clean with no stored faults from the repeated failed start attempts.

The whole thing took about twenty minutes. She asked if I thought she needed new fobs entirely. I told her not based on what I was seeing. Sometimes the simple answer is actually the answer.

She mentioned she'd almost called the dealer first and had mentally written off the rest of her afternoon to a service appointment. She saved both the time and a chunk of what the dealer would have charged just to look at it.
