Keyless rv lock

Bought one at a rally for a decent price. We were at the beginning of a two month trip and I didn't get to installation for a couple of weeks. Had some issues at first, so I let it sit in my tool box until we got home. After installing it, the latch lock (not the deadbolt) key jammed and stopped working - the remote was still fine, but I didn't like the idea of not being able to open it with a key (just in case!). Contacted the maker and was told the thing only had a thirty day warranty! Got a new key-type lock from Amazon and put it on.
