05 excursion with keypad on driver door.

When I lock the door using the inside door lock button on the drivers side it will lock all of the doors and then a second later unlock just the drivers door. It does not do it when I use the key fob to lock doors or when I lock the doors using the passenger side door lock. Does anyone know how to fix this?

 

This must be the fault in the programming the key with the lock, contact an auto locksmith for resolving the issue.

 

Check the inner wiring of the door, i am sure the problem must be there and it can be resolved easily without hiring a locksmith.

 

You might try shooting a little WD40 into the lock assy and see if it makes any difference.
