Abstract
A motor vehicle including a central locking system as well as an anti-theft alarm system is controlled by a control unit common to both systems. The locked state and the unlocked state of all locks or doors of the motor vehicle are monitored by means of additional switching contacts and an activating of the alarm system is prevented if at least one of the locks is not in the locked state. An activating of the alarm ready state of the alarm system is nevertheless possible by operating a key-operated lock a certain number of times within a specific limited time period.
