Keyless Entry, Immobilizer And Anti-Theft Systems Description And Function

Keyless Entry Components: 

Technical Description: 

Keyless entry:

Keyless entry allows the user to lock and unlock the doors of the vehicle without using the mechanical key. The user is able to remotely lock or unlock the vehicle by pushing the corresponding button on the key fob.

To unlock the vehicle with keyless entry, press the button on the driver's door. The smart key must be within a range of about 1 meter from the receiver antennas located in the driver's door and the tailgate. To lock the vehicle, press the button on the driver's door handle with the smart key within 1 meter of the outside of the vehicle.

Immobilizer:

The immobilizer is an electrical device fitted to the vehicle which aims to deter vehicle theft by preventing the vehicle from being started without the appropriate key fob. The immobilizer functions automatically without the need for manual activation or intervention.

The immobilizer indicator is briefly displayed on the instrument panel when starting the vehicle. If the immobilizer system recognizes the key fob correctly, the indicator light turns off.

Anti-theft systems:

The alarm system automatically arms your vehicle after you lock the vehicle with the key fob or touch the sensor on the door handle.

The following scenarios will activate the alarm system:

If any door is opened without using the key fob while the vehicle is locked

If the tailgate is opened without using the key fob while the vehicle is locked

If the vehicle hood is opened while the vehicle is locked

If the alarm is activated, the lights and/or alarm siren will sound, depending on the vehicle settings. If the vehicle is paired to a C-App account, the C-App will also display a message.

Operation: (Use Cases)
