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

Fits snugly in the doorway but won't close from the inside. The locking lever just floats there. Does not connect to the locking mechanism to block the lock. I would go back, but I had to fiddle with the POS so many times to get it working that I dropped my keyboard. It still lights up, but I scraped some paint off the fairing, and I also removed the insulating foam tape from the inside, thinking the problem might be that it's not working. Incorrect! It just doesn't work. And my doorway is exactly the dimensions this position requires.
