Not really weird, so much as awesome.
I used to do car lockouts for AAA Motor Club back in the 90s. If you locked your keys in your car, and called AAA, I would show up with my handy bag of tools and sort you out.
One of those tools was a handheld key cutter. Now this is before fobs, and probably isn't even in use today, but back then, it was crucial. Basically, old car keys had various cuts to give them their teeth. 6 cuts on older GM keys, for example. When on call off-hours, as I was in this case, with no access to the shop, you'd call dispatch with the VIN, they'd call the automaker, give the VIN, and they'd give the cut depths. Dispatch then relays the info, you set the little levers on the handheld to match the depths, put in a blank, and punch out a new key.
On one particular job, I show up on the west side of Chicago (not a good area), late Friday night, 1am-ish, and raining like hell. I get the VIN, and go to call it in, but my radio's dead. It had power, but just wasn't connecting to dispatch. Cell phones weren't really a thing at that time, and we were in the middle of some dark ass street, with no pay phones in sight. I (and by extension, the customer) was pretty much hosed. But I figured I'd give it my best shot.
The lady had left her keys on the passenger seat. Doing my best to get a good look at the door key with a flashlight, through a wet window in a downpour, I made a best guess at its cut depths. Popped in a blank, set the levers, a little clicky clicky clicky, put the new key in the door, said a little prayer, turned it... and it opened right up.
I was the hero of the day (night). Felt good, man.
I also worked at Red Lobster for about 45 minutes. But that's a story for another time...
