Hey there thanks for the question.The door lock issue is likely not the FOB this time around to be honest. The only reason I say that is because the alarm goes off when open the door. This indicates the BCM is not actually seeing the unlock signal from the fob otherwise it would disarm.Most lock issues are simple by this one not so much because it could be the actuator itself or an issue at the key cylinder switch or something of that nature giving the unlock signal.
