14. The decoupling device of claim 13, wherein the controller provides an unlock signal when the probe indicates that the magnetic lock member has been released and sends the unlock signal to the external host system.

15. The decoupling device of claim 12, wherein the probe further comprises an optical scanner operable to detect a change of reflectivity of a security status indicator of the storage container, wherein the change of reflectivity indicates that the magnetic lock member has moved from a first position in which the storage container is locked, to a second position in which the storage container is unlocked.

16. The decoupling device of claim 15, wherein the optical scanner is connected to the controller and provides an unlock signal when the optical scanner indicates that the magnetic lock member has been released.

17. A decoupling device for use in unlocking a storage container that includes a container body and a magnetic lock member disposed at a lock portion of the storage container, the decoupling device comprising:
