Seat Leon >> Electronic immobiliser

The immobiliser prevents unauthorised persons from driving the vehicle.

Inside the key there is a chip that deactivates the electronic immobiliser automatically when the key is inserted into the ignition.

The immobiliser will be activated again automatically as soon as you pull the key out of the ignition lock.

The engine can only be started using a genuine SEAT key with the correct code.

Note
 The vehicle cannot be operated properly if you do not have a genuine SEAT key.
