Good evening I an looking for a good dead bolt lock for my pole barn entry door. One that can not be bumped. Anyone use the electronic ones? Thanks
Anything worth that much I'd use redundant security. You know lock on the door, lock on the floor (expensive stuff in a concrete pouring chamber in the floor), lock on the box (box in the concrete pouring chamber).
Or...just insure it and throw whatever on the door.
Typically I just buy what I can find in store usually that means "master" lock. If a thief has the will they'll go right through that though. Could just cut the door itself (if it's a wood door; barn=assumed don't know what a pole barn is though).
Most thiefs will just brute force it anyway. That's why you have redundant security. Depends on the state but booby traps might be an option; behind a locked door it's probably not a legal issue unless they are lethal traps.
At the point you need to protect it, it's probably just best to have insurance. Protect the hand and power tools that aren't mounted but everything else the schmucks probably won't bother with.
