hmmm good point, how does one lock the boot if there is no power? will lock mechanism manually engage? would have been great if the kill off switch cabling could be passed through /under the mat in rear and side panel near the 12v sockets at rear, much easier, but suppose if you had kids jumping around in the rear and kids got curious they could kill the battery whilst you are doing 100 on a motorway, not good i guess
