I replaced my battery several weeks ago and since then randomly my car unlocks itself. While I am driving I can hear the doors unlocking, even though the doors are already unlocked. It so random, it may happen once while I am driving or it can happen a half a dozen times. I even tried parking the car and sitting in the car while I turn off my engine and locking my car and after some time it unlocks itself. Its very random cause i lock my car when I leave it and most of the time in the mornings my car is still locked. Remember my car just unlocks itself not locks. Weird.

Please Help
