1999-2003
Enter vehicle, close and lock all doors.
slowly insert and remove key from ignition 6 times within 10 seconds. The tail lamps will flash to indicate original code has been erased. Turn ignition to the ACC position.
Press any button on 1st transmitter.
Hazard lamps will flash to confirm programming.
TO enter additional transmitters, unlock then lock the doors using the power lock switch located on the driver door.
Press any button on additional transmitter (up to 4 tansmitters total possible). Hazard lamps will flash to confirm programming.
open the driver's door.
Turn ignition off.

You must re-program all existing transmitters as this process erases codes from car.

if it is a ford remote or ford factory alarm remote cycle the key from off to run(usually 8 times) untill you hear door locks activate. at this exact time key needs to be in the on position.touch unlock or lock on all remotes being programmed and make sure door locks respond to remotes. then turn key off ending programming mode.then try your fobs they should work
