I have the keyless entry on my 2012 31.5FBHS. I don't know the brand, but it does not look like the one pictured above. It has a separate key pad on the door. To my knowledge it does not have a battery and operates with power from the camper battery. Thus far, I have not had any problems with it, however, when activated, the mechanism moves with such force as to jar the door which worries me.
