Over the past few years I’ve noticed two things about my model of car, a 97 Honda Civic. a.) Green like mine is a fairly popular colour, b.) the key to my Civic opens any other Civic of the same type.
You can see how a.) led to b.), my mother (who used to own it) my girlfriend and I have all stumbled upon Hondas the same colour as mine in car parks, unlocked them, gone to get into the car and suddenly realised there’s a lot of stuff in there that isn’t ours.
The immobiliser chip in the key would hopefully stop anyone else driving off with my Honda, but from a legal point of view, is it ok for a company to have a car that can be opened with any key made for the rest of the model line? One person could conceivable steal a key (or even use their own) to swipe something from the boot or front seat of any car in a city, without drawing attention to themselves at all.
