> My 99 Prizm key would work for most all other Chevy Prizm cars.
I accidentally stole a bike in college, because it was the same brand as mine, and had the same brand of lock. Got all the way back to my dorm before I realized that the reason the seat felt weird was that it wasn't mine. But my key worked!
I also used my apartment deadbolt key to let my girlfriend into her house when she accidentally got locked out. She was both horrified and grateful that it worked. (I expected that one to fail, but I figured why not try?)
I'm not sure what the trick is to finding locks that aren't vulnerable to this trick. I suspect it's "buy locks at least 50% more expensive than the cheapest option", but that's just a guess.
Most locks are only useful to deter those who apply a minimal level of effort to circumvent them. And that is good enough for a huge majority of cases.
