Replacing the key battery
We recommend you have the batteries changed in a specialist
garage. If you decide to change the used battery yourself, follow the
steps below:
– Carefully prise apart the key
using a coin.
– Remove 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.

Operating instructions
For the sake of the environment
Used batteries must be disposed of appropriately and must not be discarded
with ordinary household waste.
Note
•
The system must be re-synchronised after each battery replacement to be
able to lock and unlock the car using the remote control ⇒ page 103.
•
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 electronic
immobiliser is enabled automatically when the ignition key is removed from
the ignition lock after coming to a stop.
B
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 correct
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.
