As several people pointed out in the comments it did take him longer than picking a lock would… for him.

Faster than the padlock he power sawed before finding “Oh, the back just screws off”.

I enjoyed his dig about these things being designed by people who don’t have experience designing locks. I once made the mistake of buying an early digital camera made by HP - a company that didn’t know anything about optics, as I found out to my chagrin.

Consider an interchangeable core padlock. To remove the core, you have to unscrew an alen bolt located in one of the shackle holes. To get a screwdriver into the shackle hole, you have to unlock the padlock. Sometimes the bolt is hidden inside the other shackle hole – meaning that the entire shackle must be removed. It is possible to implement this solution poorly.
But generally, if you don’t have the key-- you’ll have to pick the core (or shim it, but that’s a defeatable exploit).

Even some companies that should know better, design locks that can be unscrewed. The Kwikset base-model double-cylinder deadbolt has one screw in each cylinder face. If you can get a smidgeon of access to the other side (which is why you would use a double-cylinder lock in the first place) then you can remove both cylinders and unlock the lock.

I’ve given up on locks. Now I wipe vaseline on door knobs to make them too slippery to twist open.

Easy fix- replace the screws with an exotic security screw, like a penta screw or something from Bryce Fasteners (they make custom security screws with one-off patterns, including a Penta-plus)
Except that would drive the cost up a significant amount.

Interesting approach. What do you do for brute force?

Well, HP DOES know about how to make printers and yet they still managed to fuck that up many, many times over.

Explosives always work for brute force. BOOM! Didn’t work the first time? Apply bigger explosives. Might take out the door but you’ll also take out the lock

Not really, all the good HP printers have engines made by somebody else like Canon.

Vaseline on the floor, of course. Imagine trying to use one of those rams on a vaseline’d floor.

Well, that’s the exception to Hanlon’s razor. There has to be at least one.
If they’re locking something up with such a deluxe anti-theft, alleged supposedly break-in proof lock then Burglar Maxim #2: If it is locked up good, it’s something worth stealing

That’s when the “lawyer” part of “Lockpicking Lawyer” comes in handy!
