So I decided to give the RVlock company entry door lock a try. So far so good. Install was what others have said. Enlarge bottom of the old door lock opening until the new lock fits in and follow the instructions.
I would say it’s a 10 minute install. That’s 10 minutes of watching the videos, 10 minutes of removing the old lock, 10 minutes of enlarging the lock opening, 10 minutes of bolting the new lock in and finally 10 minutes of adjusting and lubricant.
