Replacing a Lost Ranger key-less Entry Remote
Purchase a new remote control that works with your Ford Ranger's model year.
Unlock all doors on the Ranger.
Place the key in the ignition and turn the ignition switch from the off to the on position eight times in rapid succession without starting the vehicle. On the eighth turn to the on position, the locks will cycle through the lock/unlock phase. Leave the key in the on position.
Depress the lock or unlock button on the new key-less remote. Do the same with each additional remote that goes with the Ford Ranger.
Turn the ignition switch of the vehicle to the off position and press the lock or unlock button on each remote to verify the remotes are programmed. If all remotes have been programmed, each remote will activate the door locks. If all the remotes do not activate the door locks, repeat the process.
