Chinook RV

I need to repair my existing locks. Instead of repairing my old one, has anyone found a keyless entry system that works on the chinook 2001 concourse.

I bought a piston form Amazon and made a bracket to hold it. I taped the wire going to the front doors so they all work together. Had to take door apart to run wiring and secure bracket for piston. (note: the white bar across door has nothing to do with lock. It just makes it easier to shut door than using the original handle)
