1. A security apparatus adapted to be detachably installed in a vehicle which includes: a first receiver which is configured to receive a first signal including a first ID code, which is transmitted from a transmitter; a storage storing a second ID code; a control unit which is configured to determine whether the first ID code included in the received signal is in conformity with the second ID code stored in the storage, and to output a second signal only when the first ID code is in conformity with the second ID code; and a door lock controller which is configured to lock or unlock a door of the vehicle in response to the second signal, the security apparatus comprising: a security unit which is configured to switch a security mode between on and off states; a second receiver which is configured to directly receive the first signal; and a detecting unit which is configured to detect whether the door lock controller locks or unlocks the door when the second receiver receives the first signal, wherein when the second receiver receives the first signal and the detecting unit detects that the door lock controller locks the door, the security unit switches the security mode into the on state; wherein when the second receiver receives the first signal and the detecting unit detects that the door lock controller unlocks the door, the security unit switches the security mode into the off state; and wherein when the second receiver receives the first signal and the detecting unit does not detect that the door lock controller locks or unlocks the door, the security unit does not switch the security mode.
