2020 AUDI A3 immobilizer

Opening and closing

the vehicle within a short time to remove
the vehicle key, then the vehicle will lock au-
tomatically. This prevents the vehicle from
being left unlocked for long periods of time.
The key will then be locked inside the vehi-
cle.
— If the convenience key* that was used last is
detected inside the luggage compartment,
it will not be possible to lock the luggage
compartment and the luggage compart-
ment lid will open. The turn signals will
flash several times to indicate this. The
doors will lock. Always take the convenience
key with you, or unauthorized people may
be able to enter the vehicle.
@ Tips
— Do not leave valuables unattended in the ve-
hicle. A locked vehicle is not a safe!
— The LED in the driver's door rail blinks when
you lock the vehicle. If the LED lights up for
approximately 30 seconds after locking,
there is a malfunction in the central locking
system. Have the problem corrected by an
authorized Audi dealer or authorized Audi
Service Facility.

Number of keys
You can check the number of keys assigned to
your vehicle in the Infotainment system. To do
this, select the [MENU] button > Vehicle > left
control button > Service & checks > Vehicle in-
formation. This way, you can make sure that you
have all the keys when purchasing a used vehicle.


Replacing a key
If a key is lost, see an authorized Audi dealer or
authorized Audi Service Facility. Have this key de-
activated. It is important to bring all keys with
you. If a key is lost, you should report it to your
insurance company.
Electronic immobilizer
The immobilizer prevents unauthorized use of
the vehicle. Under certain circumstances, the ve-
hicle may not be able to start if there is a key
from a different vehicle manufacturer on the key
chain.
Data in the master key
During driving, data that is relevant for service
and maintenance is continuously stored on your
master key. Your Audi service advisor can read
out this data and tell you about the work your ve-
hicle needs. This applies also to vehicles with a
convenience key*.
@) Note
Protect the remote control key against high
temperatures, direct sunlight, and moisture.
@) For the sake of the environment
° Do not dispose of remote control keys in
household trash. They contain materials that
can be recycled. Contact an authorized Audi
dealer or authorized Audi Service Facility for
more information.
Gi) Tips
— The operation of the remote control key can
be temporarily disrupted by interference
from transmitters near the vehicle working
in the same frequency range (such as a cell
phone or radio equipment). Always check if
your vehicle is locked.
