Abstract
A theft-prevention system for a motor vehicle wherein at least one cylinder lock having a closing cylinder and a switching mechanism that is relatively translatable with respect to the closing cylinder for actuating and deactuating the cylinder lock is engageable by a first key which is able to actuate and deactuate only the cylinder lock, and a second key which is engageable with the cylinder lock for actuating and deactuating both the closing cylinder and at least one auxiliary system for deterring the theft of the vehicle. Actuation of the auxiliary system by the second key engages a locking mechanism preventing operation of the cylinder lock.
