The procedure for returning the key 131 to the operator is:

the first step: the operator applies for returning the key 131 corresponding to the lock 200 to the main control unit 300.

And a second step of: after the main control unit 300 authorizes, the control circuit controls the limiting piece 152 of the locking module 150 to be switched to the avoiding position, and meanwhile, the first indicator lamp is turned on to remind that the key ring unlocking device 100 corresponding to the key ring module 130 to be restored is unlocked, and the second indicator lamp 201 is turned on to remind the position of the lock 200 corresponding to the key ring module 130 to be restored.

And a third step of: if the key ring module 130 extends into the key ring unlocking device 100 within the preset time after unlocking, the control circuit controls the limiting piece 152 of the locking module 150 to be switched to the stop position again, so that the locking piece 151 is in the locking position, and meanwhile, the first indicator lamp and the second indicator lamp 201 are turned off, and the locking process is ended; if the key 131 is not returned after the preset time after unlocking, the control circuit controls the limiting member 152 of the locking module 150 to switch to the stop position again, so that the locking member 151 is in the locking position, and the first indicator lamp and the second indicator lamp 201 are turned off, and the locking process is ended.

After the key 131 is not removed in time or returned in time, which causes the locking module 150 to be locked again, the operator is required to apply for unlocking or returning again on the main control unit 300, and the unlocking process or the locking process is restarted.

Optionally, the control circuit determines whether the key fob module 130 is returned or removed by whether the key information code of the wireless chip 135 is acquired.
