I just bought a Ford Explorer key fob off of Amazon and it came with instructions as to how to reprogram my car. Having follored this, as well as reading the manual and various posts online, my car fails to accept it. Here is what I mean:

The instructions say to insert the key into the ignition and turn from off (where the key is able to be inserted and removed) to on (2 clicks beyond off) 8 times, then on the 8th time to leave the key in the on position. If done correctly doors are supposed to cycle locked - unlocked. My Doors do not. I sat in my car for a good 30 mins turning it on and off to no avail. My car did come with lojack, but I disabled it.

Any ideas as to how to reprogram my car? I have the two keys and 2 original fobs (which are giving out).

Some auto parts stores (in my case AutoZone) have a display that tests key fobs. You point yours at it and the display lights if it works. Since yours is of unknown reliability verify that it works. – mikes Aug 11 '12 at 13:19

Are you sure these instructions are applicable for a 1998? – Mark Johnson Aug 15 '12 at 20:27
Positive. its even in my manual. – Xander Luciano Aug 26 '12 at 8:29
If so equipped, disable the autolamp function prior to cycling key. – user12156 Sep 10 '15 at 19:19

Looking online, the only difference I see as to what you are doing and what is suggested is to turn the key eight times within 10 seconds. It may be you are not getting all of the key turns in within the allotted time. For the entire sequence, the following steps are applicable (so others know when looking):

  1. Have all transmitters available before starting, as even programmed remotes will need to be done again.
  2. Place key in the ignition and rapidly turn from OFF to ON positions eight (8) times within 10 seconds finishing in ON position. Do not engage starter.

  3. If doors do not automatically lock/unlock, repeat step 2.

  4. Press one button on every transmitter.
  5. Turn ignition to LOCK and remove key.
  6. Check the operation of all transmitters.

Hope this helps.
