Abstract

A locking system includes at least one electrical locking member for a door and at least one key member. Each electrical locking member is associated with a first communication member for wireless communication over short distances, and each key member includes a programmable, mobile unit including a second communication member for wireless communication over short distances. The electrical locking member is unlocked or locked by the fact that the second communication member encryptedly transmits an address unique to the second mobile unit, as well as an authorized user code to the first communication member.

Locking system according to claim 19, comprising a central processing unit connected to the electrical locking member, the central processing unit comprising a memory member for storage of the unique address of the mobile unit and the authorized user code, and the central processing unit being adapted to provide a signal to unlock or lock the electrical locking member.

21. Locking system according to claim 19, wherein each first communication member is connected to a first memory member adapted to store the unique address of the mobile unit as well as the authorized user code.

22. Locking system according to claim 21, wherein each electrical locking member is associated with a comparing member connected to the first communication member and the first memory member and adapted to compare and confirm agreement between the unique address of the mobile unit and user code received from the second communication member with the address and user code in the first memory member.

23. Locking system according to claim 22, wherein the electrical locking member remains in a locked state when the comparing member does not establish agreement.

24. Locking system according to claim 19, wherein the first and second communication member, respectively, are adapted to communicate by means of Bluetooth technology.

25. Locking system according to claim 24, wherein each mobile unit comprises a selecting member operable to select one of three different operating modes of the mobile unit.

26. Locking system according to claim 25, wherein, in a first operating mode, the mobile unit is adapted to search, by means of the pair information, for electrical locking members and, if more than one electrical locking member is registered in a second memory member included in each mobile unit, the first mobile unit is adapted to display a list on a display member included in each mobile unit, the first mobile unit being adapted to permit a user to select from the list which electrical locking member of the more than one electrical locking member should be unlocked or locked.

27. Locking system according to claim 25, wherein, in a second operating mode, the mobile unit is adapted to search, by means of the pair information, automatically for electrical locking members that are registered in a second memory member included in each mobile unit at a predetermined time interval when the mobile unit finds at least one electrical locking member within a predetermined distance from the mobile unit, the mobile unit being adapted to display on a display member included in each mobile unit a question if the locking member found should be unlocked or locked.

28. Locking system according to claim 25, wherein, in a third operating mode, the mobile unit is adapted to search, by means of the pair information, automatically for electrical locking members that are registered in a second memory member included in each mobile unit and, when the mobile unit finds at least one electrical locking member within a predetermined distance from the mobile unit, the mobile unit being adapted to unlock or lock the locking member.

29. Locking system according to claim 28, wherein the mobile unit is adapted to send an SMS message comprising an erasure code to the mobile unit, the user code being erased in the mobile unit.

30. Locking system according to claim 19, wherein each mobile unit comprises a mobile telephone or a hand-held computer.

31. Locking system according to claim 30, wherein each first communication member is connected to a first memory member adapted to store the unique address of the mobile unit as well as the authorized user code, and wherein the first communication member, the first memory member and the third memory member are integrated in the electrical locking member.

32. Locking system according to claim 30, wherein each first communication member is connected to a first memory member adapted to store the unique address of the mobile unit as well as the authorized user code, and wherein the first communication member, the first memory member and the third memory member are arranged in a change-over switch connected to each the locking member and arranged to enable opening of the electrical locking member from inside.

33. Locking system according to claim 19, wherein a key member comprises a stationary unit.

34. Method of using a locking system, the locking system comprising at least one electrical locking member and at least one key member, the key member comprising a programmable, mobile unit, for wireless unlocking or locking of the electrical locking member, the method comprising:

storing pair information in a third persistent memory member connected to a first communication member associated with the electrical locking member, the pair information allowing a mobile unit to unlock or lock an electrical locking member;

transmitting an encrypted address unique to the mobile unit to the first communication member by a second communication member included in the mobile unit, the second communication member being adapted for wireless communication over short distances; and

unlocking or locking the electrical locking in response to the transmitted unique address.

35. Method for wireless unlocking or locking of one or more electrical locking members according to claim 34, comprising:

storing at least one unique address of the mobile unit and at least one authorized user code in a central processing unit connected to each electrical locking member; and

determining whether the electrical locking member should be unlocked or locked with the central processing unit and sending a signal from the central processing unit to unlock or lock the electrical locking member.

36. Method for wireless unlocking or locking of one or more electrical locking members according to claim 34, comprising:

storing at least one unique address of the mobile unit and at least one authorized user code in a first memory member connected to the first communication member.

37. Method for wireless unlocking or locking of one or more electrical locking members according to claim 36, comprising:
