– Remove the cover in the direction of the arrow.
– Remove the used battery from the cover.
– Insert the new battery. Make sure that the “+” symbol on the
battery is facing downwards. The correct polarity is indicated on
the cover.
– After inserting the battery, align the cover and key and press
the two parts together.
For the sake of the environment
Used batteries must be disposed of at an appropriate waste facility or
through an authorised service, given that their components can affect the
environment.
Note
● The system must be re-synchronised after each battery replacement to
be able to lock and unlock the vehicle using the remote control
⇒ page 106.
● The new battery must be of the same type as the original.
Electronic immobiliser
The electronic immobiliser is designed to prevent unauthor-
ised persons from starting up the vehicle.
There is an electronic chip inside the key which automatically deactivates
the immobiliser when the key is inserted into the ignition lock. The electron-
ic immobiliser is enabled automatically when the ignition key is removed
from the ignition lock after coming to a stop.
If an uncoded key is used, the message SAFE will appear in the trip recorder
display.
Note
● The engine can only be started using an original SEAT key with the cor-
rect code.
● It may not be possible to start the engine with the key if there is another
ignition key from a different make of vehicle on the same key tab.
