Same basic principle as any lock pick. Apply tension, bump tumblers into place.
Not only that, there are lists of combinations based on serial numbers, too.
My Master Lock padlock duo from starting HS in '72 was listed. Not that I forgot, having the numbers seared into my memory from all those openings, but I was curious.
In the steel shop where I worked, we often fabricated tool boxes for construction worker’s tools and explosives. One of the ways we fixed the locking latch was to build a steel box around the latch welded to the lid so you had to reach IN, then UP to get to the lock.
There was no way to get bolt cutters in, and no way to get a hammer in, and the opening was too small to get any sort of pick in at all.
If you lost your key you were OUT OF LUCK! Then it was cutting torch time. We used this on lots of dynamite boxes.
Insurance doesn’t cover someone coming into your house and killing everyone.
My parents, when they lived in Crown Heights, NY, had their door kicked in during the Crown Heights pogrom, simply because they were Jewish/Israeli. They were met by mother with a shotgun and fled.
Still, it is best to have the perimeter harder to breach.
Hardened doors, windows, and locks are part of that.
Hazardous duty opening boxes of dynamite with a cutting torch?
We just built them. If the construction people were dumb enough to lose the key it was their problem.
I also built several gunpowder storage lockers with the same lock setup.
The same technique works on terrorists to unlock information
A big dog and a handgun.
It all comes down to knowing how things work and how/why they are built that way.
I can open most of the old combination locks with a little tension and a good feel for the dial. For keyed locks, a hammer was the most efficient method. For a door lock that you find on glass office doors, a pair of channel lock pliers and strong little finger.
I’ve “hotwired” a number of vehicles in my life and it really only comes down to how much damage you are prepared to inflict, locking steering came be a challenge.
If you can overcome the locking steering than all you need is a paper clip.
I always carry a paper clip with me.
Did you make the guy who forgot his key use the torch?
Got that covered...

I always figured the expansion of the stacked plates jammed up the works any way. Not so much that it was a good lock
