1. A lock device adapted to unlock a lock by transferring a lock catch from a locking position to a releasing position, said lock device comprising: an electric motor mechanically connected to an axle via at least one transmission device, rotation of the axle actuating the lock catch; andmeans for monitoring current consumed by the electric motor, the lock device based on the monitored current, stopping a transfer of the lock catch before the lock catch reaches a permanent stop. 2. The lock device of claim 1, further comprising: means for evaluating the monitored current; andstorage means for storing current characteristics regarding the current. 3. The lock device of claim 2, wherein the lock device is configured to determine whether the lock device is in a locked/unlocked state or not based on a comparison between the monitored current and the stored current characteristics. 4. The lock device of claim 2, wherein the lock device is configured to determine the type of lock that the lock device has been applied to, based on a comparison between the monitored current and the stored current characteristics. 5. The lock device of claim 1, wherein said at least one transmission device comprises a weakening structure adapted to break and disrupt the mechanical connection between the electric motor and the axle if a threshold force is exceeded. 6. The lock device of claim 5, wherein the at least one transmission device comprises a gear wheel comprising a central region, a peripheral region, and an intermediate weakening region including the weakening structure. 7. The lock device of claim 5, wherein the weakening structure comprises a structural weakening. 8. The lock device of claim 5, wherein the weakening structure comprises an adhesive bond, releasably bonding the central region to the peripheral region. 9. The lock device of claim 5, wherein the weakening structure comprises at least one structure extending radially between the central region and the peripheral region. 10. A method for locking/unlocking a lock with a lock device having a motor controller controlling an electrical motor mechanically connected to a lock catch of the lock and a device capable of monitoring the current consumed by the motor, said method comprising: sending instructions to a motor controller to actuate the motor in an opening direction;monitoring current consumed during the operation of the motor;comparing the current consumed as a function of time with reference current characteristics;determining when the lock is locked/unlocked based on said comparison; andstopping actuation of the motor, wherein the actuation is stopped prior to the lock catch reaching a permanent stop. 11. A method comprising: using a lock device according to claim 1. 12. The lock device of claim 2, wherein the current characteristics regarding the current is a preset value being a threshold value or a reference curve. 13. The lock device of claim 3, wherein the lock device is capable of determining the type of lock that the lock device has been applied to, based on a comparison between the monitored current and the stored current characteristics. 14. The lock device of claim 7, wherein the structural weakening includes apertures, recesses or cavities in the weakening region. 15. The lock device of claim 6, wherein the weakening structure comprises a structural weakening. 16. The lock device of claim 15, wherein the structural weakening includes apertures, recesses or cavities in the weakening region. 17. The lock device of claim 6, wherein the weakening structure comprises an adhesive bond, releasably bonding the central region to the peripheral region. 18. The lock device of claim 6, wherein the weakening structure comprises at least one structure extending radially between the central region and the peripheral region. 19. The lock device of claim 7, wherein the weakening structure comprises an adhesive bond, releasably bonding the central region to the peripheral region. 20. The lock device of claim 7, wherein the weakening structure comprises at least one structure extending radially between the central region and the peripheral region. 21. The lock device of claim 1, wherein the axle is a rotatable axle directly contacting the lock catch. 22. The lock device of claim 1, wherein the axle includes a manual operating knob at one end of the axle and the other end of the axle engages the lock catch. 23. The lock device of claim 1, further comprising a DC power source stored in the lock device.
