SECURITY/CENTRAL LOCKING – CIRCUIT OPERATION

Remote Handset Operation

The handset has two buttons, lock/superlock and unlock. The operation is as follows: Lock - single press of lock button  Superlock - double press of lock button (within  1 second) Unlock - single press of unlock button from ei ther locked or superlocked.

Locking operation

There are six different ways to lock a new Range Rover. These are:

Sill Locking

 Depressing either of the front door sill buttons while both front doors are closed will result in all the doors and the tailgate locking, and the vehicle entering a sill locked state. In this state the alarm remains inactive (provides no protection), with no LED flash. Sill locking can be achieved independently of key-in and ignition switch status.

Slam Locking:

 Depressing either of the front door sill buttons with either front door open, will result in all the doors and the tailgate locking and the vehicle entering a slam locked state. Following a slam locking operation, the alarm will enter the perimetric mode, engine crank will be disabled and electronic engine immobilisation will be activated. Attempting to slam lock the vehicle with either the key in the ignition, or the ignition on, will cause unlocking of all the doors.

Key Locking

 A single turn of the key towards the front of the vehicle will result in all the doors and tailgate locking. The alarm will enter the perimetric mode, engine crank will be disabled and electronic engine immobilisation will be activated.

Key Superlocking

 A double turn of the key in a clockwise direction (i.e. towards the front of the vehicle) within 2 seconds, provided the doors, tailgate and bonnet are closed, will result in all the doors being superlocked. The alarm will enter the perimetric mode, engine crank will be disabled and electronic engine immobilisation will be activated.

Remote Locking

 A single press of the lock button on the remote handset will result in all the doors and the tailgate locking. The alarm will enter the perimetric mode, engine crank will be disabled and electronic engine immobilisation will be activated.

Remote Superlocking

 A double press of the lock button on the remote handset within 2 seconds, provided the doors, tailgate and bonnet are closed, will result in all the doors being superlocked (subject to ultrasonic look around - see Ultrasonic Sensor). Providing all the windows are closed, the perimetric and volumetric alarm will be set. If all the windows are not closed, then only the perimetric alarm will be set. Engine crank will be disabled and electronic engine immobilisation will be activated.
