2004 Keypad won't unlock, only locks

[Adam Smith]

I have never replaced the battery in the door (if there is one). It took 15 minutes of trying this morning to get in my door. I can press the last two buttons at the same time, and I hear it try to lock all the doors (they are already locked), but pressing my code no longer works.
Thank you.

AHHHH I have the SAME problem...... It can be just bad key pad.... ( powered by the truck No battery's). a broken wire in the hinge of the door, or a bad module for the keypad.
I have not traced mine down, but I changed my key pad and it worked for 6 months, then died. Put the keypad in another truck and it works, that trucks doesn't in mine.... So I know mine is now a hunting and fishing game to figure it out.
