An alarming and unlocking system and method are provided to prevent theft of a vehicle due to lost of the identification key without weight increase or tuning of load sensor. An alarming and unlocking system comprises a BCM+ smart key unit(10), an interior sensing antenna(20), a Fob key(30), a driver door module(40), a door switch(50), a door handle switch(60), a Fob holder(70), a door lock/unlock actuator(80), and an exterior buzzer(90). The BCM+ smart key unit transmits a signal searching the Fob key to the interior of the vehicle. The interior sensing antenna inputs the Fob key sensing signal to the BCM+ smart key unit. The Fob holder confirms insertion of the Fob key and inputs the insertion confirmation signal to the BCM+ smart key unit. The door switch outputs a door opening signal when the vehicle door is opened or closed. The door handle switch outputs a door lock/unlock signal when the vehicle door is locked or unlocked. The door lock/unlock actuator operates in response to a lock/unlock command signal to lock or unlock the door. The exterior buzzer outputs alarm sound in response to a driving signal. |
