A car manufacturer that reused the same car key for every car.
The automobile key pool used to be small. Some Eastern European car manufacturers had only a few, the joke was they wouldn't get stolen: once you've been inside one you've had enough
And the key is a LEGO brick.
And the key on top of that can be used to open every other car that exists.
They did!
As a 90s kid, the Dodge Omni was a common shitbox student car. I think they had like 8 key patterns lol.
My brother’s ignition key unlocked my friends’s trunk. There were a few people who could start other peoples cars. In one case, a soccer player “stole” a football players unlocked car as they looked identical and were parked near each other. In another as a prank we unlocked cars to roll them out of parking spots and physically lift them into unusual places.
Beyond that, they didn't even properly key the key! They carved one notch in by hand!
And the key has no notches, and so inserting a screwdriver into the lock and turning works just as well as using the key.
