Keyless Entry won't lock truck

[Ron Favaloro]

I have a 2001 Sport Trac with keyless entry. All functions (ncluding lights in keypad) work fine but I the lock function using the 7/8 & 9/0 pressed together has stopped working. I replaced the keypad but it did not fix the problem. Any suggestiions?

does your code include the 7/8, 9/0 numbers? If not, there may be a broken wire from one of those 2 buttons. If your code does include them, then I have no idea.
