Upon departing the Lake Havasu rally, we headed south to a wildlife refuge along the Colorado river. We always lock the coach with the key fob remote. When we came back, the door would not unlock. Oops, now what?
Our coach has a Trekmate alarm system which controls the door lock. Trek Mate is out of business. Somehow, the alarm could no longer communicate with the fob.
I had the keys, and could get into the bays, but that was all. Called Marathon and Prevost for advice, they could not solve the problem. They suggested relieving all the air pressure from the auxiliary system by draining the fittings at the rear and below the driver seat compartment. No luck. The lock would not open.
So, we removed a side window. Flipped the button by the door both ways and it popped open. Then it started to rain.
Put the window mostly back in ( even though it had a crack now) and spent the night. Next morning finished putting it in on a bright sunshiny morning.
Prevost gets $500 a piece for those side windows, only $175 for a windshield. Amazing. I will replace it again after we get home with a new one.
So, what we need is a back up plan in case the fob does not work. I plan to wire in a parallel switch accessible from below the driver seat compartment, which will activate the lock the same way that the alarm does.
I do not want to go through this again!
