Love our RVLock as well. Haven't used the front door key in 3+ years.
I'd love to hear what problems people are having with these. I had keyless entry on our sticks and bricks forever, and it was one of the first things to install on our current RV when we bought it back in 2016. Never had any issues with any of them.
I only wish there were Z-Wave compatible models on the market for automation and record keeping, as we have a Ring Alarm system that would integrate with.
