SAFETY SYSTEM FOR CONTROL OF THE ACCESS TO AN OBJECT
A safety system is provided for control of the access to an object with a lock, that can alternatively be locked or unlocked by a mechanical key subsystem and by a remote control key subsystem offers the possibility to intentionally deactivate a remote control key subsystem by using for example the mechanical key subsystem when locking the object. Later, the remote control key subsystem can be reactivated by using the mechanical key subsystem again for unlocking. This way, the use of the remote control key subsystem can be prevented in situations where a theft of a remote control key is more probable than in other situations.
1 . A safety system for control of the access to an object by locking and unlocking a lock, comprising:
a mechanical key subsystem; and
a remote control key subsystem, said remote control key subsystem comprising a first communication unit fixed to the object and a second communication unit that is mobile,
wherein the remote control key subsystem can be deactivated intentionally and wherein the remote control key subsystem can be reactivated by using the mechanical key subsystem on the lock.
2 . A safety system according to claim 1 ,
wherein the remote control key subsystem is deactivated by using the mechanical key subsystem for locking said lock.
3 . A safety system according to claim 1 ,
wherein the remote control key subsystem is deactivated by using a mechanical switch fixed to the object.
4 . A safety system according to claim 1 ,
wherein the remote control key subsystem is deactivated by using a mechanical switch fixed to the object and accessible only when the object is accessible.
5 . A safety system according to claim 1 ,
wherein the remote control key subsystem is deactivated by using it to transmit a deactivation command to the first communication unit.
6 . A safety system according to claim 1 ,
wherein the remote control key subsystem is deactivated by deactivating the first communication unit with a command sent from the second communication unit.
7 . A safety system according to claim 1 ,
wherein the remote control key subsystem is deactivated by an input to the second communication unit and wherein said input deactivates said second communication unit.
8 . A safety system according to claim 1 ,
wherein said object is a vehicle.
9 . A safety system according to claim 1 ,
wherein said object is a car.
10 . A safety system according to claim 1 ,
wherein said object is the motor of a vehicle.
11 . A safety system according to claim 1 ,
wherein said object is a house or a garage.
12 . A safety system for control of the access to an object by locking and unlocking a lock, comprising:
a mechanical key subsystem; and
a remote control key subsystem, said remote control key subsystem comprising a first communication unit fixed to the object and a second communication unit which is mobile,
wherein the remote control key subsystem can be deactivated intentionally and wherein the remote control key subsystem can be reactivated by using a digital access code input to said second communication unit.
13 . A safety system according to claim 12 ,
wherein the remote control key subsystem is deactivated by using the mechanical key subsystem on the lock of the object.
14 . A safety system according to claim 12 ,
wherein the remote control key subsystem is deactivated by using a mechanical switch fixed to the object.
15 . A safety system according to claim 12 ,
wherein the remote control key subsystem is deactivated by using it to transmit a command to the first communication unit with the effect that the first communication unit does not react to further commands from said second communication unit.
16 . A safety system according to claim 12 ,
wherein the remote control key subsystem is deactivated by switching off said second communication unit.
17 . A safety system according to claim 12 ,
wherein said object is a vehicle.
18 . A safety system according to claim 12 ,
wherein said object is a car.
19 . A safety system according to claim 12 ,
wherein said object is the motor of a vehicle.
20 . A safety system according to claim 12 ,
wherein said object is a house or a garage.
