2004 Ford Expedition Remote Head Key Replacement - Fast, Affordable & Professional

She was at a restaurant in Otay Mesa, over near the Ocean View Hills side, and her purse was gone off the back of her chair. Car keys, house keys, wallet, phone. All of it. She borrowed the hostess's phone and called the police first, then her husband, then me.

Her 2004 Ford Expedition was sitting in the restaurant parking lot with zero keys. The dealer told her husband it would be a three-to-five-day wait, the Expedition would have to be towed in, and they strongly recommended rekeying the locks on top of that since the stolen key could still get into the car. The combined estimate was not a small number.

I got there that same evening.

All-keys-lost is a different job than adding a spare key when you still have one working. With a working key present, the system trusts the existing key and just adds a new one to its memory. All-keys-lost means I wipe the entire key memory and enroll fresh keys from zero, so the stolen fob is permanently dead to that vehicle. I accessed the immobilizer through the diagnostic port, cleared the old key data, and programmed two new remote head keys from scratch. Cut the blade to her vehicle, verified both fobs locked and unlocked the doors, confirmed the engine started clean on each one.

She finished her police report. I finished the job. She drove home that night.

The stolen key can still physically insert into the door lock, but the immobilizer will not let the engine start. That was the part her husband kept asking me to confirm, so I walked him through it before I packed up. The dealer's tow-and-wait route would have left the Expedition in that lot until mid-week. She was home before midnight.
