Abstract

The present invention provides a door lock drive mechanism comprising an electromotor (2) having a stator, a shaft (4), which is adapted to be rotated by energization of the stator, and a magnet blocker (16) having a through-hole (17), through which the shaft (4) extends such that the magnet blocker (16) surrounds the shaft (4) in its entire circumferential direction, such that the through-hole (17) in a neutral position, is coaxial to the shaft (4) and not in contact with an outer circumferential surface of the shaft (4), the through-hole (17) defines an inner circumferential surface of the magnet blocker (16) and the magnet blocker (16) comprises a material which can be attracted by an external magnet (15). In order to counteract the manipulation of a door lock drive mechanism with an external magnet, the magnet blocker (16) is adapted in that upon bringing the external magnet (15) from a direction perpendicular to an extension direction of the shaft (4) in a vicinity of the magnet blocker (16), the magnet blocker is moved from its neutral position into an engagement position with the shaft (4), such that the inner circumferential surface of the magnet blocker (16) comes into contact with the outer circumferential surface of the shaft (4), such that a form- and/or force-fit is provided therebetween, such that a rotation of the shaft (4) due to induction of a magnetic force in the stator, when the external magnet (15) is moved around the shaft (4) in the circumferential direction, is prevented. Further, it is provided a method for updating a door lock drive mechanism.
