4. Step-by-Step Guide to Audi B6 Key Fob Programming

Follow these steps to program your Audi B6 key fob successfully. Remember to stay organized and patient.

Method 1: Reprogramming Existing Keys

If your keys were previously linked to the car, follow these steps:

Hold Unlock Button: Press and hold the unlock button on the remote.
Insert and Turn Ignition: Insert the key into the ignition and turn to the “on” position (while still holding unlock).
Hold in On Position: Continue holding the unlock button for 2 seconds while the key is in the “on” position.
Turn Off and Remove: Turn the key to the “off” position, remove it from the ignition, and release the unlock button.
Repeat: Repeat this process for each remote you want to reprogram.
Relink Seat Positions: To relink to seat positions, press and hold the memory position number button, then press the unlock button for 2 seconds and release both.

Method 2: Programming New Remotes

If you are programming new remotes that have never been linked to the car:

Insert First Key: Take a working key (a valet key works well), insert it into the ignition, and turn the key to the “on” position, so the dashboard lights come on.
Roll Down Window: Roll down the driver’s side window (this is a precaution in case there’s an issue).
Exit and Close Door: Exit the car and close the door.
Physically Lock Door: With a second key, physically lock the doors by turning the key clockwise (do not use a remote).
Press Unlock Button: Take the first remote to be programmed and press the unlock button. The lights will flash once.
Wait and Press Again: Wait 10 seconds and press the unlock button again. The doors should unlock. The first transmitter is now programmed.
Lock Door Again: Lock the door again (physically) with the key by turning clockwise.
Press Unlock Twice: Press the unlock button two times with a one-second interval in between. The lights will flash with each button press, for a total of two flashes.
Wait and Press Again: Wait 10 seconds and press the unlock button. The doors should unlock. The second transmitter is now programmed.
Repeat for More Keys: Repeat steps 7-9, increasing the number of presses by one for each additional key. For example, press the unlock button three times for the third key, and four times for the fourth key.
Remove Key: Remove the key from the ignition.
