The Pandora BT-780 is a Bluetooth immobilizer tag for the modern Pandora and Pandect alarm systems.
The tag is used to identify the car owner: if an attempt is made to start off without this tag, the ignition (and/or) the fuel system are disabled.
The Pandora BT-780's body is sealed with ultrasound, which makes it much more durable. Replacing the battery has also become a lot easier.
