2020 Defender



Before exiting the vehicle, always select Park (P) switch off the ignition, apply the Electric Parking Brake (EPB) and remove any smart keys. Missing these steps may lead to serious injury or death.


No modifications or additions should be made to the security system. Such changes could cause the system to malfunction.

Before attempting to lock the vehicle, always make sure of the following:

  • The ignition is switched off.

  • All of the doors, the windows, the bonnet, and the taildoor are closed correctly.

Briefly press the lock button on the smart key to lock the vehicle and arm the perimetric alarm. The hazard warning lights flash to confirm.

Single locking secures the vehicle and prevents the doors from being opened from the outside. The doors may still be unlocked and opened from inside the vehicle.


The single locking setting should be used in circumstances when pets remain in the vehicle, or if a window must be left open.

Once armed, the alarm activates if:

  • The bonnet, taildoor, or a door is opened.

  • The engine START/STOP button is pressed without a valid smart key present.

  • The vehicle's battery is disconnected.

  • An attempt is made to disconnect the battery back-up sounder.


Always secure the vehicle when left unattended. Where possible, always secure the vehicle to the maximum available level of security.


In some markets, the full alarm system, including the alarm sensors, is armed when the vehicle is single locked. The alarm sensors can be enabled and disabled, for one alarm cycle only, via the Vehicle menu in the touchscreen. See SYSTEM SETTINGS.
