I was on a construction site and the construction trailer was brought in. Its door was padlocked. No Key. With a rotary saw (gas powered) and a metal cutting disk it took about 4 minutes to open. 3 minutes and 50 seconds was trying to get the saw started. Locks are generally a mild deterrent and "proof it was broken into". reducing access to the shackle seems to be more popular. Those big metal construction boxes put the lock inside the box with only access to the bottom of the lock. Doesn't help against pickers, but you'll have to cut through the steel box to get inside. https://images.homedepot-static.com/catalog/pdfImages/f1/f19a2bd1-41c4-4efd-849d-09bfb172dc88.pdf https://images.homedepot-static.com/catalog/pdfImages/f1/f19...

There are different materials for locks, some of which are considerably more resistant to cutting tools. Security devices like that are not about absolute prevention but about the time, effort, and expertise required to open them.

  Abrasives always win[1]. Always. The best you can hope for is to make the abrasive less efficient.

    Abrasives always win if you have a lock in your garage and a week to open it. If you're a thief with a battery powered angle grinder and a cheap one at that, it is quite possible that a high quality lock will defeat you. There are alloys that will just eat cutoff wheels and jam up low powered battery powertools. It's always the case that there exists a way to defeat a lock, it is not always the case that a particular person in a particular situation can defeat a lock.

> Locks are generally a mild deterrent and "proof it was broken into". Exactly this. This is why the American style locks that are vulnerable to bump keying are so very very bad. Anyone with a $1 tool and a mallet with zero skills can break in without a leaving a trace.
