All our other trailers had keyless entry systems, keyfobs or touch pads. We went online and found rvdoorlocks.com. They make a few different systems to replace the door lock handles with handles with built in touch pads that also have keyfobs. Installed both front and back doors of our 380, took 15 minutes each with only a screwdriver...
They synced the keyfobs so both fobs work either door.. works great...
