When I was a kid in the 90s, a teacher in the school shut their car door with their key inside. It was late into the afternoon and the school was a ways out, so with no expectation that they could get service any time soon, other teachers started trying their own keys. To everyone's surprise, out a car key from a totally different make and model worked. The details of that one instance are obviously fuzzy at this point, but if I had to guess, it might have been made possible thanks to the AutoLatina JV https://en.wikipedia.org/wiki/AutoLatina https://en.wikipedia.org/wiki/AutoLatina
