Hello everyone. I recently purchased a 2002 Sport Trac (Limited?) with 4WD. The prior owner never used the keypad and I wanted to program my own code into it. I have the original programming code which was not only on a card in the glovebox, but also matched the one on the module behind the passenger airbag. My issue is that the code is not working. The keypad works in that I can press the 7/8 and 9/0 keys at the same time to lock the doors. HOwever, when I enter the programming code, the doors do not unlock. Nor was I able to program a new code using the procedure in the user manual. Anyone encounter this issue before?
