Q: I bought it used and it didn't come with the Owner's Manual, hopefully someone can give me direction so I can program this feature on my Mountaineer Greatly appreciat some help Thanks :)

A: You will need the original factory programmed keyless entry keypad code to program your own code. To locate the original keypad code, open the right/rear door. Pull the on-body rubber weatherstrip out, around the rear side of the door closure. Fold the right/rear seatback down into the locked position to facilitate access to the right/rear seat belt anchor. Carefully pry the upper plastic panel that houses the height adjuster and seat belt anchor off the body taking care not to damage the panel. Now pry the lower panel outward just far enough to enable access to the Vehicle Security Module, where you'll see three electrical connectors plugged into it, coloured green, grey, and blue. On the module will be a series of digits on a label similar to 5L2T-15K602-EA. Beside those digits are five numbers. Those five numbers are the keyless entry keypad code. Once the original keypad code has been obtained, you will need to enter it, press the 1/2 button within 5 seconds to activate the programming mode. Holding the 1/2 button for more than 2 seconds after activation will erase the the code you programmed. The existing code will not need to be erased to program a new code. Within 5 seconds, enter the new 5-digit keypad code. The door locks will lock and unlock to confirm the new code is programmed. Hope this helps.
