RV Keyless Entry
Just do a google for best price, I got mine off Ebay.

I have the same Bauer keyless lock. Im on my second one. The first one which I bought about a year ago failed on the first trip out. After I called the company they sent me out the newer version. She admitted to me that the early ones had problems and would prematurely fail. In my opinion its one of those deals where there should of been a recall.
Im only telling you this in the event that you start to have problems. Call the company and they will send you the newer updated version. They will want the old one back and they will pay for all the shipping. Since Ive been using the second one its worked fine and we really like it.
Another thing you want to use in them is the Lithium batteries.
