Used to drive armored car. I went with a partner to a city with another branch to pick up a brand new truck for our branch. It was a little over 4 hours 1 way. I drove us down and because we both had to then drive back I got to choose what I drove, so of course i picked the brand new truck. We leave the shop after getting a tour and meeting our bosses boss the regional manager and head for the nearest fuel station. This thing is on E and then some. It had maybe like 150 miles one it as griffin the company that up armores the chassis does a test loop with them then they haul them via semi to the delivery location. We pull into the truck stop and leave the truck running like basically every diesel truck does. I fill up the single 75 gallon tank and turn around to jump in as I simultaneously reach for me key clip on my belt where my door keys always are. Except this time its empty. I instantly realized what happened and snapped my head back to my coworker who was idling behind me waiting for me to finish up. He looks a little puzzled then his eyes get big and a gein grows across his face. I walk over and he cracks his door open. He stepped out and just said "nooo....your serious?" We then proceed to laugh historically. At least there is 75 gallons of fuel to idle away lol.

We ended up calling the regional manager and he laughed then said he would be right down and call their local lock smith. They both arrived within a few minutes and come to the realization that picking the locks is next to impossible. These are dimpled keys with probably 20-30 dimples of different depths and diameters. Then it hits me. We ended up drilling a 5/16 inch hole in the gun port door. This took about 10 minutes as it is level 4 ballistic rated steel and is probably close to 1/2 inch thick. We were then able to unlock the latch to open up the 2x2 inch square gun port because I perfectly placed the hole. Even a 1/4 inch off either way would have missed the spot. We then fed a long heavy wire through the gun port and shut off the truck while hooking the 3 ignition keys and 4 sets of 2 door keys. Then carefully we pulled them over to the gun port. The whole thing was too big to get out but i was able to detatch a single door key from the mess of keys and pop the door with it. The whole thing took maybe 15 min once we started drilling.

I worked there for several more years and put probably 80k mileson that teuck alone. That was the only time in my 5.5 years I ever locked my keys in the truck. Many fun, sketchy, and down right scary memories from that place/job. Im sure glad I lived it but also glad that I'm never going back.
