Central locking system
Description
The vehicle can be locked and unlocked via the central locking system.
There are several methods, depending on the vehicle equipment:
● key with remote control ⇒ page 91,
● lock on driver door (emergency opening ⇒ page 97) or
● interior central locking switch ⇒ page 93.
Unlocking one side of the vehicle only
When you lock the vehicle with the key, the doors and the rear lid are
locked. When you open the door, you can either unlock only the driver door,
or all the vehicle doors. To select the required option, use Easy Connect*
⇒ page 92.
Central locking (Auto Lock)
The Auto Lock function locks the doors and the rear lid when the vehicle ex-
ceeds a speed of about 15 km/h (10 mph).
The vehicle is unlocked again when the ignition key is removed. Alternative-
ly, the vehicle can also be unlocked via the central locking switch or by pull-
ing one of the inside door handles. The Auto Lock function can be switched
on and off on the sound system or on the Easy Connect* system
⇒ page 92.
In the event of an accident in which the airbags inflate, the doors will be au-
tomatically unlocked to facilitate access and assistance. Anti-theft security system (Safelock)
1)
The following message is displayed on the instrument panel to remind the
driver that when the vehicle is closed from the outside, the anti-theft securi-
ty system is switched on.  Do not forget the Safelock. Please see Instruction
Manual. The vehicle cannot be opened from inside. This makes it more diffi-
cult for unauthorised persons to break into the vehicle ⇒ .
The anti-theft security system can be switched off each time the vehicle is
locked:
● Turn the key a second time to the lock position, in the door lock, for the
next two seconds . If necessary, remove the protective cover on the driver
door handle ⇒ page 97. or
● Press 
on the remote control key for a second time
for the following 2
seconds.
The flashing frequency of the diode in the door sill immediately confirms
the process. Initially, the diode flashes in a fast sequence for a brief period,
then it stops for approximately 30 seconds and, lastly continues flashing
slowly.
Anti-theft alarm system*
If the anti-theft alarm system senses interference with the vehicle it triggers
an audible and visible alarm.
The anti-theft alarm system is automatically switched on when locking the
vehicle. It switches off when the vehicle is unlocked from a distance.
When the driver door is unlocked with the key, you should switch on the ig-
nition within 15 seconds. Otherwise the alarm will be triggered. On some
export versions, the alarm is triggered immediately when you open a door. 
1)
The availability of this function depends on the vehicle equipment.

87
Opening and closing
To deactivate the alarm, press the button 
on the remote control key, or
switch on the ignition. After a certain time, the alarm will automatically
switch off.
Switch off the vehicle interior monitoring and tow-away protection if you
wish to prevent the alarm from being triggered accidentally ⇒ page 95.
Turn signals
The turn signals will flash twice when the vehicle is unlocked and once
when the vehicle is locked.
If the signals do not flash, this indicates that one of the doors, the rear lid or
the bonnet is not closed correctly.
Accidental lock-out
The central locking system prevents you from being locked out of the vehi-
cle in the following situations:
● If the driver door is open, the vehicle cannot be locked with the central
locking switch ⇒ page 93.
Lock the vehicle with the remote control key, when all the doors and the rear
lid have been closed. This prevents the accidental locking of the vehicle.
WARNING
Do not leave anyone (especially children) in the vehicle if it is locked from
the outside and the anti-theft security system* is enabled, as the doors
and windows cannot then be opened from the inside. Locked doors could
delay assistance in an emergency, potentially putting lives at risk.
Note
● Never leave any valuable items in the vehicle unattended. Even a locked
vehicle is not a safe.
● If the diode on the driver door sill lights up for about 30 seconds when
the vehicle is locked, the central locking system or anti-theft alarm* is not
working properly. You should have the fault repaired at a SEAT Official Serv-
ice or specialised workshop.
● The vehicle interior monitoring of the anti-theft alarm* system will only
function as intended if the windows and the sunroof* are closed. 

Vehicle key
With the vehicle key the vehicle may be locked or unlocked remotely
⇒  page 86.
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 90 or the battery changed
⇒ page 90.
Different keys belonging to the vehicle may be used.
Unfolding and folding the key shaft
Press button 1
⇒ Fig. 43 or ⇒

To fold the shaft away, press button 1
and fold the key shaft in until it
locks in place.
Alarm button 1)
Only press alarm button 2
in the event of an emergency! When the alarm
button is pressed, the vehicle horn is heard and the turn signals are switch-
ed on for a short time. When the alarm button is pressed again, the alarm is
switched off.
Replacing a key
To obtain a spare key and other vehicle keys, the vehicle chassis number is
required.
Each new key contains a microchip which must be coded with the data from
the vehicle electronic immobiliser. A vehicle key will not work if it does not
contain microchip or the microchip has not been encoded. This is also true
for keys which are specially cut for the vehicle.
The vehicle keys or new spare keys can be obtained from a SEAT Official
Service, a specialised workshop or an approved key service qualified to cre-
ate this kind of key.
New keys or spare keys must be synchronised before use ⇒ page 90.

CAUTION
All of the vehicle keys contain electronic components. Protect the vehicle
keys from damage, impacts and humidity.
Note
● Only use the key button when you require the corresponding function.
Pushing 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.
● Key operation can be greatly influenced by overlapping radio signals
close the vehicle working in the same range of frequencies, for example, ra-
dio transmitters, mobile telephones.
● Obstacles between the remote control and the vehicle, bad weather con-
ditions and discharged batteries can considerably reduce the range of the
remote control.
● If buttons ⇒ Fig. 43 or ⇒  Fig. 44 on the vehicle key, or one of the central
locking buttons ⇒ page 93 are pressed repeatedly in short succession,
the central locking is briefly switched off to protect against overloading. The
vehicle is then unlocked. Lock the vehicle if necessary. Control lamp on the vehicle key
Fig. 45 Control lamp on
the vehicle key
When a button on the vehicle key is pressed, the control lamp flashes
⇒ Fig. 45 (arrow) once briefly. If the button is pressed and held down, the
lamp flashes several times, for example: for the convenience opening func-
tion.
If the vehicle key control lamp does not light up when the button is pressed,
replace the battery ⇒ page 90. 
