My door locks randomly lock and unlock while driving. I have verified that the key fob is not being bumped while in transit. Could this be caused by a low battery in the key fob? The problem has gotten worse each day until it is almost constantly locking and unlocking.

Remove battery to eliminate FOB as cause, if locking stops, then FOB is cause, if not then recieving unit in car.
