A REMOTE control power key, with rolling security code, operates the dome lamp and engages door deadlocks when pressed twice. It also operates the central locking for keyless entry through the driver's door only, or unlocks all doors when the button is kept pressed. The indicators are unable to flash confirmation if the door is left ajar when remote locking. The engine is disabled to immobilise the vehicle when the key is removed from the ignition. The S joins other Commodores with an alarm system, operated via remote control power key, which sounds the vehicle's horn when triggered.
