I have power bay doors. In 7-1/2 years, I have only used the key fob to unlock the doors. In the past, using the lock function on the key fob locked the entry door, and all bay doors at the same time. I could use the fob to unlock all of the bay doors at once, even if the entry door was locked or unlocked.
Today, I went out to put something in a forward bay, and when I clicked on the fob, the only bay doors that unlocked were 1) the little door behind the rear curbside tires, just before the battery bay and 2) the door for the power cord reel on the other side. None of the other bays will unlock. I tried several scenarios, none worked. I don't hear the usual click on any of the doors that don't unlock, indicating the plunger is working.
In the entire time we've had the coach, I've never used the keys. So, I tried them. The only keys I have other than the ignition, fuel doors, and engine compartment are Tri-Mark 225, Tri-Mark 853, and Tri-Mark 211. None of them will unlock the bay doors. I think the TM853 is for the front door. I think the TM211 is for our previous coach. I have no idea what the TM225 is for.
Does the door system have a fuse somewhere? I don't have a wiring schematic for my coach, and if I did, I have no idea how to read it. I'm thinking of taking the cover off the mechanism of one of the doors which is locked, but not latched at the moment, to see if it is getting current.
My key-less entry has never locked or unlocked bay doors. It still works for locking and unlocking the entry door.
Any ideas would be appreciated.
