Review on Kohree RV Keyless Entry Door Lock: Backlit Keypad with App Control, Waterproof & Easy to Use for Travel Trailers and Campers by Barton Perez

When I installed this lock, everything went smoothly and the instructions were sufficient. I made sure everything worked and was programmed on the bench before removing the old/original lock from my Nash trailer. Yesterday after the installation everything worked. Today, after 1 day, the latch does not engage. I took it off and tried it on the dyno and it doesn't click on the dyno either. I was really hoping there wouldn't be any problems with this lock as it took a while to convince the little lady of the benefits of keyless entry. 1 star because 0 stars were not possible in the event of a failure on the 2nd day.
