The present invention relates to a device for locking and unlocking leaves of a motor vehicle. The device is characterised in that it comprises a portable transmitter circuit (1) which permanently transmits a periodic signal of limited range for a specific relatively long period of time, in such a way that a receiver circuit (4) commands the unlocking of the locks (5) of the leaves of the vehicle by receiving the periodic signal from the transmitter circuit (1) within a specific time interval and commands the locking of the locks (5) when it does not receive a signal from the transmitter circuit (1) during this time interval. The invention is used in the sector of motor vehicles. <IMAGE>
