The invention relates to an anti-theft device (1) for a steering column of a motor vehicle, said device (1) comprising: a bolt (7) mounted such that it can move in translation in the device (1) between a position in which the steering column is locked and a position in which the column is released, and a means (15) for controlling the movement of the bolt (7). The device also comprises a drive means (9) connecting the control means (15) and the bolt (7), said drive means (9) including a housing (20) that receives at least part of a locking element (19) when the locking element (19) is in the rest and active positions. The aforementioned locking element (19) is configured to co-operate with the control means such as, in the active position, to lock the drive means (9) when the bolt (7) is in the locked position.

A device may receive an arming signal associated with immobilizing a vehicle. The device may monitor, based on receiving the arming signal, a current associated with an electrical power output from a battery of the vehicle. The device may detect that a measurement of the current satisfies a threshold associated with an ignition component starting an engine of the vehicle. The device may control, based on detecting that the current satisfies the threshold, a bypass circuit to reduce the electrical power output to prevent the ignition component from starting the engine.

Systems and methods for activating electric vehicles and for reducing parasitic power draw from batteries of electric vehicles are provided. An electric system of an electric vehicle includes a main battery for powering an electric motor configured to propel the electric vehicle, an ancillary battery having a smaller size than the main battery, and a signal generator using power from the ancillary battery to generate a power-on signal to cause the electric vehicle to transition from the inactive state to an active state in response to a vehicle activation command. The main battery is electrically disconnected from any electric control units of the electric vehicle during an inactive state of the electric vehicle.

A key unit authenticates a portable terminal based on information acquired from the portable terminal and controls locking and unlocking of a target by transmitting a signal to a locking and unlocking device. The key unit includes: a first communication unit configured to receive a request signal transmitted in a first frequency band from the locking and unlocking device; a controller configured to authenticate the portable terminal and process signals transmitted to and received from the locking and unlocking device; a second communication unit configured to perform short-range wireless communication with the portable terminal in a second frequency band; and a substrate on which the first communication unit, the controller, and the second communication unit are mounted. The first communication unit and the second communication unit are mounted at positions facing each other across the controller, on the substrate.
