Put two sets of keys to the car, each of which consists of the ignition key and a key for locks of doors.
So the set of keys of the car looks: 1 – a key for locks of doors; 2 – a key for inclusion of ignition; 3 – label.
Number of a key for inclusion of ignition is applied on a label in a linking of one of sets. Having removed a label from a sheaf ring, you can keep privacy of numbers of keys.
Number of a key for locks of doors is applied on a key surface.
