An anti-theft auto-lock which comprises a key switch (1) locatable adjacent to the controls of a motor vehicle; a cylinder (5) locatable adjacent to the engine block of the motor vehicle; a piston (6) moveable within the cylinder and a conduit (4) extending between the cylinder and a security shell enclosing the key switch (1). The conduit (4) and cylinder (5) contain means for reciprocally moving the piston (6) through a predetermined distance within the cylinder (5). A restoring spring (7) for piston (6) is accommodated within the cylinder (5). Also a micro-switch (13A) means is associated with the piston and cylinder assembly and is electrically incorporated in the motor vehicle's ignition circuit.
