Our ACE 30.1 had the bottom lock type. We replaced it with a Bauer electronic lock shortly after we got the coach as I didn’t want to have to deal with keys except in an emergency. I looked at RVLock, but you will find a number of posts where people found they had to modify their screen doors, which is somewhere I didn’t want to go. The RVLock does give you a lot more combinations.
We had a Bauer on our previous travel trailer and it worked fine. The Bauer for the ACE fit well, but I ended up using the original door frame strike plate as the coach appears to have been build around it. The Bauer front plate is a bit smaller than the OEM so the decals don’t go to the edge any more.
The one problem I’ve had is that the Bauer seems to want to reset itself back to the default codes. It’s happened several times. I’m guessing that while driving the batteries lose contact momentarily which causes the reset. Only takes a moment to reprogram back to our normal code. I used lithium batteries instead of Alkaline and there could be a small dimension difference or the battery springs aren’t strong enough.
