automatic UnLock and lock not working on front right (front passenger) door

When I unlock the door and lock the front right (front passenger) door manually it works fine. It will not lock or unlock with the key fob or switch on the door. I have no issues opening and closing the door. When its locked it will not open. When its unlocked it opens just fine with no issues at all. The ONLY issue I have is it not automatically locking and unlocking with the switch on the door and the key fob. Do you know what is wrong and if so what part?

Thanks in advance :)
