Review on 🔒 Enhance Security with AP Products 013-509 Electric Travel Trailer Lock by Ryan Yap

I just installed it so 5 stars are not guaranteed. Installation was easy. The only mistake was that I changed the default code before installing. I couldn't get it to work. I used the default code and it worked fine. Apparently, if the power is completely removed, the code will reset to the default. I have not tested this by removing the batteries. If so, I would keep the source code somewhere in case it doesn't work after changing the battery.
