Abstract

The invention discloses a key with a prompting function, which comprises a key body. The rear end of the key body is provided with a shell; a circuit board, an insulating strip and an alarm light are arranged in the shell; the circuit board is provided with a control circuit; a left sensor and a right sensor are connected with the control circuit; the insulating strip is arranged between a key handle of the key body and the circuit board; the alarm light is connected with the control circuit, and the light body of the alarm light is embedded on the shell and can be seen from the outside; and the insulating strip and the key handle are integrated closely and are close to the left sensor and the right sensor. When the key with the prompting function is used for unlocking a lock, one sensor is triggered, the alarm light lights up and keeps a flashing state till the lock is locked up again with the key, and then the other sensor is triggered and the alarm light puts out and cancels the alarming state. Since the alarm light flashes to catch the attention of people to prompt people to take the key and lock a door; if an owner still forgets to lock a door, once finding that the alarm light keeps flashing, the owner can be prompted to go back to lock the door, and therefore, the situation that the owner goes back to check the door when the owner remembers not locking the door suddenlycan be avoided.
