Try cycling the key on/off 8 times with the 8th time ending in the on position.
The door locks should cycle up and down to indicate you are in learn mode.
Press any button on the new remote to program to vehicle (locks should cycle to confirm program). If you have other remotes program them at this time too.
This works on quite a few Ford vehicles, give it a try.
