At work a few weeks ago they couldn’t find the key to the new Freon cage they got so I mentioned I had a lock-pick set. I was in the Master Lock within 10 seconds, they thought I was a wizard.
I just looked at them and said I’m a prepper. (They already knew)
Had a bunch of LOTO (Lockout, Tagout) padlocks from when I worked, only one key. Use em all the time and If it's MY padlock, and the key is missing, it's an easy open:
I learned in a class which family knew about. Since I'm related to everybody around here... . Seems a lot of people lose keys, mostly for padlocks (easy). I got asked so often it was simpler to keep a set of lock rakes in my truck.
It's been a while since i was asked, might need to practice a little.
