While bowling one cold winter night back in the 1960’s.
One of the guys said he was going to warm up his car, another his tossed keys and said’blue Chevy across from you’.
He started the wrong Chevy!
IIRC they had two keys, one door, and a separate ignition?
Rumor had it that there were only about a dozen different keys, but the number of combinations made for an unlikely match?
I had a car that you could start on a cold day, pull the key out and lock the door then go in the house fore coffee, come out 15 mins later and unlock the toasty warm car..
I was like “I know this ignition is worn out, but this should be a FEATURE!”
About 1954 or ‘55, Mom and Dad came out of a cocktail party in LA and drove the wrong baby blue Ford station wagon home. The key fit and turned the car on just fine. I’m sure Mom & Dad weren’t in any shape to identify the right car.
