I'm bringing a locked file cabinet with me to work. How can I tell if anyone tries to mess with the lock???

Question

I am a nail tech and I think my products and my nail drill have been messed with. :(

Answer 1

As a locksmith, I have to ask is it a padlock or built-in.

If it is a padlock of your own choosing, buy a good one incorporating anti-pick features by a reputable company.
Those by abloy / baton that use a half-moon keyway are particularly good against picking.
If it is built-in.... Paint it - at least the front. Most picking attempts will leave scratches as a tell-tale.
If your stuff is still messed with, use a strong epoxy or nuts and bolts to put another hasp on it and use a padlock as described above.
You can always use a bike lock through the handles, or a cable arrangement.
You can also fit a basic alarm with a keypad in there !
