Once again I need help. Have left my coach parked with everything hooked up and AC on at my lot for about a month. Had a friend check on my bus today and times before and when she keyed in the code the door did not unlock. Had a little trouble before with code lock being slow and having to punch numbers a couple of times. Now I am 1000 miles away and she can't get in to check on bus. Please help! Thank you, Mike Shaw
