I have a 2022 Thor Four Winds 31W. The lock on my side entrance door just broke, and I cannot find a replacement lock anywhere that fits. I have seen other postings where owners are in search of a keyless lock that works in this opening. At this point, I would be happy with the same crappy, original lock.
I would call Thor first and they will send you a replacement lock since you are still under warranty. It is easy to remove and replace. No need to take it to a shop for that repair. On my other coach, Thor sent me some replacement parts when I called them while under warranty.
