At one time in America, keys from one car would unlock, if not start, many thousands of similar cars because of similar or same key bitting. It's interesting that German cars of the same era were harder to break into because of worse economics for lower classes, more car thefts and therefore more secure vehicles... meanwhile American cars weren't really locked that much because post-WW2 boom times were so good, and so, less theft, especially in small towns where everyone knew each other and theft would risk becoming a shunned criminal outlaw.
