Padlock and chain through handles of power tools then to something that dont move helps (the one in plastic boxes i cut the shape out box.) saying that they tried once and failed and guess what they came back with bolt cutters and got my new makita. So get a bulkhead and new vans should have deadlocks. I have also seen a transit back door where they used a crow bar on a deadlocked door what a mess
