Remote control key or convenience key
Number of keys
You can check how many keys are initialised for your Audi A3 using the MMI*. This feature enables used car buyers to make sure they have received all of the keys. To do so, select MENU button > Car > control button Systems* > Servicing & checks > Initialised keys.
Replacing a key
If you should lose a key, please contact an Audi dealer. Have the remote control coding for that key deactivated. For this purpose you should bring all available keys with you. It is also important to notify your insurance company if a key has been lost.
Immobiliser
The immobiliser is designed to prevent unauthorised persons from driving the Audi A3. It may not be possible to start the engine if there is another radio transmitter (e.g. an ignition key for another Audi A3 or a transponder) on the same key ring.
Data stored on remote control key or convenience key
Data related to the service and maintenance of the Audi A3 are stored continuously on your remote control key or convenience key*. Your Audi dealer can read out the data and will then be able to tell you what service work is required.
- Always take the key with you when leaving the Audi A3 - even if you only intend to be gone for a short time. This is especially important if children are left in the car. They might otherwise be able to start the engine or use power-operated equipment such as the electric windows - this could lead to injuries.
- Wait for the Audi A3 to come to a standstill before removing the ignition key from the lock. Otherwise the steering lock could engage suddenly, causing an accident.
Note
The function of the remote control key may be impaired by interference from other nearby radio signals (for example from a mobile telephone or TV transmitter) if these are in the same frequency range.
