I bought a used Ford Ranger PU that came with no remote key fob. I had 2 for the Contour, so I did some searching to reprogram one of the remotes.
BINGO.
Turn the key to run-stop-run-stop-etc 8 times inside of 10 seconds, ending with the key ON.
The locks will lock-unlock.
Press any button on the remote. The locks will lock-unlock.
Turn the key to off.
If you screw it up, turn the key off and start all over till you get it.
Sure beats paying a dealer $140 to do it, and another ton of bucks for their remote.
I sure do love the Internet.
