I watched the videos at this site and I wonder if these electronic locks could be tampered with in a way that would disable them.
My concern would be the ability for someone to break the battery slot while in that position, thus disabling the lock.
Watch the "battery jump" video. Seems to me that the slot could be intentionally damaged when in the "jump" position which might render the lock inoperable. For example, what if I took a pair of pliers and mangled the battery slot so it couldn't be pushed back in and the jump contacts were destroyed?
Perhaps a live battery would still power the lock even if the vandal opened the slot to the jump position and then mangled it. Obviously a dead battery wouldn't so it seems that at least if the timing was right, the lock could be disabled in that case.
I think i'll give Master Lock a call and see what they say.
