How to Program Audi A3 Remotes Key Fob

Summary:
In this guide, you will find instructions on how to program an Audi A3 key fob.

The following procedure will program the key fob to unlock/lock the Audi A3. The immobilizer chip must be programmed at the Audi dealer. Your other option is to have your locksmith cut and program the new key to start the car and then perform this procedure to synchronize the remote. These instructions do not work on newer Audi A3 vehicles. 

Procedure
Steps to program a key fob on an Audi.

Setp1

Start by rolling down one of the windows.

Setp2

Use a spare key to turn the ignition "on" position. All the dashboard lights come on, don't start the car.

Setp3

Get out of the car and close all the doors.

Setp4

With a second key, lock the doors using the metal key. Important: DO NOT USE REMOTE

Setp5

Use the remote that you need to be programmed to unlock the doors. Only press the unlock button once. Hint: Your lights should flash once at this point.

Setp6

Wait 10 seconds and press the unlock button again. This time, the doors will unlock. Your Audi key is programmed.

Setp7

If you need to program other keys, lock the Audi door manually. Use the metal key, not the keyfob, to lock the doors.

Setp8

Press the unlock button twice within one second. The lights will flash twice.

Setp9

Wait 10 seconds and press the unlock button again. Your Audi doors should open, and your second key is programmed.

Setp10

Once you program all the keys, remove the key from the ignition to exit program mode and test the keyfobs.

Hint: If you have a third key, repeat steps 7 through 9. Step 8, make sure to press the unlock button three times if you are programming a third key fob.

PROGRAMING EXISTING REMOTE

You need to be careful when performing this procedure because you may erase the other keys stored in the memory by programming a new key. Follow the following steps to program a new Audi key and retain all of the keys programmed.

Step1

Press the unlock button on your key fob and hold it.

Step2

While you hold the unlock button pressed, insert the key into ignition position II.

Step3

Please continue to hold the unlock button pressed for three seconds and then remove it. Your keyfob should be programmed now.
