I find it hard to believe that the clock alone would drain the battery…I have 2 thoughts: 1, are you accidentally sitting on the fob and hitting the unlock button over and over? and 2, I wonder if the fob is close enough to the vehicle that it’s putting the computer into a ready mode which would use more power than a passive state…I think it would be a good idea to have your mechanic do a parasitic draw test to make sure there isn’t something running in the background that isn’t supposed to be ---

Thank you fro responding. I have since learned that the doors unlocking themselves and the clock staying on began when the key fob quit communicating with the car.
