Question

how come every vehicle has a single key??

Answer 1

Haha It is just for the sake of convenience. You wouldn't want to have different keys for different parts of the car. That's why there's a single key for all areas.

Answer 2

This is not true.
There are usually 2 keys for a car.
If you go to a car seller (ex: Audi) and buy a car, you'll receive 2 keys, they are almost identical.
Each car manufactured have 2 keys.

And I think this is the wrong forum to pot a question like this.

Answer 9

The keys are different.
The keys are you can see if you bring up your house-key, it has a special pattern on it right?
That pattern only fits into 1 keyhole since it has the reverse pattern inside.

The difference is in the pattern, the slightest mm will determine if you can open the lock or not.
Bot the key and the key-hole\lock is designed to match each other perfectly, making it impossible for ex: me to come over to your place and try to open the door.... except if I use a crowbar *hehehe*
I hope this answered you question.
S**t! running late for school xD
