WARNING
Swallowing batteries with a diameter of 20 mm or other types of lithium
battery may quickly result in serious injuries of even death.
● Always keep the vehicle keys and the key tab with the batteries,
spare batteries, flat batteries and other types of batteries larger than
20 mm out of the reach of children.
● Immediately seek medical assistance if you suspect the swallowing of
a battery.
WARNING
Careless or incorrect use of vehicle keys may result in severe injury and
accident.
● Always take all the keys with you whenever you leave the vehicle.
Children and unauthorised individuals could lock the doors or the rear
lid, start the engine or turn the ignition on activating electrical systems,
for example: the electric windows.
● Never leave children or disabled people alone in the vehicle. They
could be trapped in the vehicle in an emergency and will not be able to
get themselves to safety. For example, depending on the time of the
year, temperatures inside a locked and closed vehicle can be extremely
high or extremely low resulting in serious injuries and illness or even
death, particularly for young children.
● Never remove the key from the ignition if the vehicle is in motion. The
steering may lock and it will not be possible to turn the steering wheel.

Remote control vehicle key*
Fig. 12 Remote control
key
Remote control key
With the vehicle key the vehicle may be locked or unlocked remotely
⇒  page 33.
The vehicle key includes an emitter and battery. The receiver is in the interi-
or of the vehicle. The range of the vehicle key with remote control and new
battery is several metres around the vehicle.
If it is not possible to open or close the vehicle using the remote control key,
this should be re-synchronised ⇒ page 31 or the battery changed
⇒  page 31.
Different keys belonging to the vehicle may be used.
Folding the key shaft in and out
When the button is pressed ⇒ Fig. 12 A
, the key shaft is released and un-
folds.
To fold it press the button and fold the key shaft in until it locks in place. Duplicate keys
To obtain a spare key and other vehicle keys, the vehicle chassis number is
required.
Each new key must contain a microchip and be coded with the data from the
electronic vehicle immobilizer. In vehicle key will not work if it does not con-
tain microchip or the microchip has not been encoded. This is also true for
keys cut for the vehicle.
The vehicle keys or new spare keys can be obtained from a SEAT dealership,
a Specialised workshop or approved key service qualified to create this kind
of key.
Synchronise new keys or spare keys before use
⇒ page 31.
CAUTION
The remote control key contains electronic components. Protect the vehicle
keys from damage, impacts and humidity.
Note
Only use the key button when you require the corresponding function. Push-
ing the button unnecessarily could accidentally unlock the vehicle or trigger
the alarm. It is also possible even when you are outside the radius of action.
Note
Remote control key operation can be greatly influenced by overlapping ra-
dio signals around the vehicle working in the same range of frequencies (for
example, radio transmitters, mobile telephones).
Note
Obstacles between the remote control and the vehicle, bad weather condi-
tions and discharged batteries can considerably reduce the range of the re-
mote control. 

Changing the battery
Fig. 15 Vehicle key: bat-
tery compartment cover
Fig. 16 Vehicle key: re-
moving the battery
SEAT recommend having the batteries changed in a Specialised workshop.
The battery is located to the rear of the vehicle key, under a cover. Changing the battery
●
Unfold the key shaft ⇒ page 29.
● Remove the cover from the back of the vehicle key ⇒ Fig. 15 in the direc-
tion of the arrow ⇒ 
.
● Extract the battery from the compartment using a suitable thin object
⇒ Fig. 16.
● Place the new battery in the compartment, pressing as shown ⇒ Fig. 16
in the opposite direction to the arrow ⇒ 
.
● Fit the battery compartment cover, pressing in the direction of the arrow
as shown ⇒ Fig. 15 until it clicks into place.
CAUTION
● If the battery is not changed correctly, the vehicle key may be damaged.
● Use of unsuitable batteries may damage the vehicle key. For this reason,
always replace the dead battery with another of the same voltage, size and
specifications.
● When fitting the battery, check that the polarity is correct.
For the sake of the environment
Please dispose of your used batteries correctly and with respect for the envi-
ronment. 
To synchronise the vehicle key
If the button  is pressed frequently outside of the vehicle range, it is pos-
sible that the vehicle can no longer be locked or unlocked using the key. In
this case, synchronise the vehicle key once more as follows:
● Unfold the key shaft
⇒ page 29.
● Press the button 
on the vehicle key. For this, you must remain next to
the vehicle. 

Unlocking and locking
Central locking* and locking system Introduction
Central locking functions correctly when all the doors and the rear lid are
correctly shut. If the driver door is open, the vehicle cannot be locked with
the key.
The battery of a vehicle left unlocked during a long period (for instance, in a
private garage) may run down and fail to start the motor.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Vehicle key set ⇒ page 28
● Doors ⇒ page 38
● Rear lid ⇒ page 40
● Electric windows ⇒ page 43
● Emergency locking and unlocking ⇒ page 243
WARNING
The incorrect use of the central locking system may cause serious inju-
ries.
● The central locking system will lock all doors. A vehicle locked from
the inside can prevent any non-authorised individual from opening the
doors and accessing the vehicle. Nevertheless, in case of emergency or
accident, locked doors will complicate access to the passenger compart-
ment to help the passengers.
● Never leave children or disabled people alone in the vehicle. The cen-
tral locking button can be used to lock all the doors from within. There-
fore, passengers will be locked inside the vehicle. Individuals locked in
the vehicle can be exposed to very high or very low temperatures.
WARNING (Continued)
● Depending on the time of the year, temperatures inside a locked and
closed vehicle can be extremely high or extremely low resulting in seri-
ous injuries and illness or even death, particularly for young children.
● Never leave individuals locked in a closed and locked vehicle. In case
of emergency, they may not be able to exit the vehicle by themselves or
get help.

Description of the central locking system
The central locking system allows all doors and the rear lid to be locked and
unlocked centrally.
● From outside, using the vehicle key.
● From inside, by pushing the central locking button ⇒ page 36.
The central locking system can be activated or deactivated at a specialised
workshop.
In case of a vehicle key fault or central locking system fault, all doors can be
locked or unlocked manually.
Locking the vehicle after the airbags have been deployed
If the airbags are deployed due to an accident, the vehicle will be automati-
cally and completely unlocked. Depending on the amount of damage, the
vehicle can be locked following an accident in the following ways: 
