I had problems with my keyless lock system...nothing like returning from a summer long trip, it's 102 temp, and you want to start the unloading process and can't open the darn camper door. The folks at RV Lock were real nice and sent me a replacement unit that sits on my work bench waiting for me to figure out what to do with it. I decided to go with the the original lock set that came with my camper. Sometimes simple works out better.
