Hey guys, I bought a 2001 F150 supercrew. Im having a problem with the keypad entry on the driver door. Entering the factory set code, the doors will lock (after pressing 7/8 or seomthing). That works fine. When following the instructions in the manual on how to lock the door, it doesn't work. Unlocking the doors is more important than locking the doors imho. Anyone have any idea what could be wrong. I really don't have time to take it to the dealer.
