Review on MKING RV Lock Keyless Entry: Secure & Convenient Keyless Door Handle for Travel Trailer Camper by Ryan Hart

Very good upgrade or replacement - I should have put it on the upgrade list sooner! Arrived well packaged and ready to install. After removing the existing normal standard lock and knobs I had to file the inside edges a bit inside and outside my door, easy, you may not have to. The instructions are easy to follow; except that when programming the fob, I had to "hold down the program button while pressing the lock button on the remote" to program it. If you're having trouble, try anyway. Once tightened, the lock sits nice and tidy. Includes a shiny new door and clamps. I was lucky and didn't need any adjustments at all. Snaps/closes so easily. The outer part of the lock is illuminated and easy to read. You can use either a key fob (1 key fob with my set), your own 4-8 digit digital code or keys (2 keys in my set). Runs on 4 AA batteries - don't know how long it will last. Pleased with the fit, finish and functionality. Installed yesterday. I'll update if I have to.
