If you've owned an older Ford truck, there was a time period when the keys on the doors were a separate key. The door key never had that much variety, it was pretty common in a large parking lot to be able to get in the wrong truck. You just couldn't start it. The only reason why it isn't so common anymore is most people aren't driving 1980s era Ford trucks in North America.

I personally spent about 10 minutes trying to enter a car one time thinking my key was broken. At that point I realized I don't own fuzzy dice and was indeed just at a different car with the exact same exterior

if most bikes look the same, yeah, a lot (dunno if the case in JP)
