How do you program a key fob for 2004 ford expedition?

Answer 1

Turn the ignition on and off 8 times (do not start the vehicle, just from the "lock" position, to the "on" position) on the 8th time, leave the key "on" and the doors will all unlock. When this happens, press both the lock and unlock button on your key FOB at the same time and presto, your FOB is programmed. If you are doing this for multiple FOB's, they need to be done at the same time.

Hope this helps.

Just to add to this because I read this and tried it. You must unlock the doors with the door switch first and then you MUST do the steps above in 10 seconds or less. The instructions are also in your owners manual under "remote".

**** SUPER EASY ****

1. Put all FOB's on one key - They do not all have to be the same FOB.

(I used one from the 2004 Explorer and one from a 1998 Explorer)

2. Get in car, shut door and UNLOCK DOORS WITH THE BUTTON ON THE DRIVERS SIDE DOOR.

3. Put Key in Ignition with ALL key FOBS hanging from it on ONE key Ring

4. TURN KEY TO "ON" Position and BACK TO "OFF" Position 8 Times ~> ON THE 8th TIME, LEAVE IT IN THE "ON" Position (Must be done within 10 seconds)

***The Doors will lock and unlock Automatically and the car will "DING" while you do the next step.

5. On each FOB, PUSH both the LOCK and UNLOCK buttons at the SAME TIME, ONE FOB AT A TIME.

6. Turn the key back to the off position and your DONE!
