Key Replacement - Save vs Dealer in San Diego

2006 Ford Mustang Transponder Key Replacement - Fast, Affordable & Professional

She was sitting at a restaurant in the Bayside area of Imperial Beach when someone lifted her purse off the back of her chair. Car keys, wallet, phone, all of it gone. She borrowed the hostess's phone, called the police, then her husband, then me.

Her 2006 Mustang was sitting in the lot with no keys at all. Her husband had already called the dealer while she was waiting. They said they could order the key, but the car would need to be towed in, and they strongly suggested rekeying the locks since the stolen key could still open the doors. The combined estimate was steep, and the timeline was measured in business days, not hours.

I got there that evening. All-keys-lost is a different job than cutting a spare. When a working key is already in the system, adding another one is relatively quick because the car already trusts something. AKL means I wipe the key memory completely so the stolen key is dead to the immobilizer, then program fresh keys from scratch. I pulled up the vehicle through the diagnostic port, cleared the old data, and programmed two new transponder keys. Then I decoded the ignition and door lock, cut both blades, and tested everything before I left the lot.

She drove home that night. The stolen key can still physically enter the lock cylinder, but the immobilizer will not let the engine turn over. That part matters a lot when a key walks out the door with a stranger.

The dealer quote involved a tow, a multi-day wait, and a number that made her husband go quiet on the phone. She paid a fraction of that, on site, same evening. I did not bring that up. She did.
