At a previous company, a power outage knocked out our router, which knocked out the card access system, which locked us out of the server room where the router was. Good news, there was a physical key bypass. Bad news, nobody knew where said key was. Lucky for us, I could pop out to my car, grab my picks, and then got the thing open in a couple of minutes.
Definitely the most above-the-board use those picks ever got (Though obtaining access to my university dorm's AC controls definitely made me more popular).
Heyyy, guerilla HVAC team!
In high school I didn't even have lockpicks, I just carried a super tiny pair of needle-nose pliers along with some other tools in my Five-Star zipper binder, and the tips of the pliers were fine enough to stab into the holes of those stupid snake-bite security screws that held down the thermostat covers in the classrooms.
Once teachers realized I could open the thermostat covers and adjust their setting in seconds instead of the hours it took to go the official route, not only was I very popular, they would occasionally send hall passes to summon me from other rooms to perform the service. I was doing fine in my studies and this was not an academic impediment, it was just hilarious. Eventually I just started leaving the covers loose, a fig-leaf that the custodial staff seemed content to ignore.
...
Fastforward a few years into my career, still not carrying lockpicks, but much more familiar with the art. A shipment of cabinetized network hardware arrived, but the cabinet keys were not ziptied to the doors as was customary. The installers were looking at having to go home with a short timesheet because they couldn't work.
I was in the NOC for another reason entirely, but I asked the supe to cover me for a minute and trotted out to the equipment room. I swiped a couple pins from the corkboard (for some reason, the office used dissection T-pins instead of regular pushpins), bent the tip of one, used the other as a turning tool, and proceeded to rake open one of the cabinets. The install crew lead's jaw hit the floor. I insisted on teaching him to do the rest, and moments later not only had he opened the rest of the cabinet doors, he had scared himself with how easy that just was, and stood in silence for a minute, shocked by his newly-acquired skill.
Very Harry Tuttle, although to be fair everything feels a little Brazil these days.
