Steve,
If you look at my prior posts, you will see that I posted a picture of the TM211 key, and said that there is an etched TM211 on the lock cylinders visible on the door handle. Last night, I went out and started the coach. I have never had to use the battery boost. The engine starts right up, so I assume the chassis batteries are fine. I will put a meter on them today. I also assume, could be wrong, that starting the coach and letting it idle for a bit, then turning it off, is the same as turning the ignition on and off to "bypass" the fob as you mention. The locks did not unlock when I did that. In all my years of ownership, I have never known the bay doors to unlock when I turned off the ignition.
Do you think it would be helpful for me to re-set the key-less entry code? The suggestion to punch in the code, and then hit '9' didn't work either. It is mentioned in my owner's manual as well.
I'm reluctant to do the "long screwdriver" method because I don't want to damage anything. Do you think a locksmith could get in to my electrical bay? That is the door that has K21 behind it, so it is the only one I think I need open for now.
Thank you for mentoring me on this problem...everyone.
Stan
Edit: Looking at the picture of my door mechanism above, (keep in mind its upside down because the door is raised) where should I try to probe with a "long screwdriver" to try to get the electrical bay door open?
