I tow a 2012 Jeep GC Overland with a Roadmaster 10k rated tow bar with Air Force One brake system. The keyless entry cover must be removed to use the "key" portion of the fob. On the 2012, you can not remove the fob without putting the ignition in the "off" position. As the previous post, you can not lock the doors without removing the fob. It's really a piece of cake to place the transmission in park and the tranny in neutral. Do all this with the engine off, and the ignition on, but motor not running. Complete and accurate instructions came in the owner's manual in the glove box. No battery use or mileage recorded. Only caveat, the LED indicator to be placed on the rear view mirror is VERY difficult to see in the rear camera of the MH. The TPMS would alert to a problem, but I would like to know when the toad brakes are activated. Considering a way to wire an indicator to the front of the MH for the toad brake lights.
