STANDARD security features on the STi include remote central locking and a keypad immobiliser alarm system. The remote central locking is integrated with the indicators so that they flash once when the car is locked and twice when unlocked. A PIN has to be entered into the keypad, which is located on the centre console beside the handbrake, before the vehicle can be started. The system provides additional points of vehicle immobilisation on top of the standard factory immobiliser, including anti-hijack mode, automatic re-arm, intrusion alert, false alarm protection, internal screamer, infrasonic sensor valet mode and anti cross-pollination software for additional theft protection.
