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.
