The arrangement has an electronic part and a mechanical lock part (1). In the electronic part is a key (2) and a code lock (3). The electronic key has an individual code which activates the code lock by being placed against its surface. When activation occurs, this is indicated by a flashing light diode (4). The code lock is applied, e.g. to the inside of the windscreen, so that the electronic key can be applied against the exterior of the windscreen centrally to the code lock. The code lock is a connected to an electronic central unit (5), to which the electromechanical lock part is also connected. The lock part incorporates a drive in the form of an electric motor or an electromagnet, controlled by the electronic central unit. - Each door of the vehicle has a lock bolt (6) and the electronic central unit can monitor the voltage over the source supplying current to the drive arrangement. When slow voltage redn. occurs, the lock arrangement changes from the locked position to the freeing position, such as with the vehicle battery having a low charge. However, the locked position is maintained when a rapid voltage variation occurs, such as with a break in the feed cable from the battery. |
