What Audi A4 is the Exeo based on, B5,B6,B7 or B8? As far as I know the Exeo started in 2009 and hasn't had a facelift as yet.
I want to search audi forums on key programing info.
I found this info on
how to program a remote to a B7 A4:-
How do I reprogram the remote control?
1. Take the valet key, put it into the ignition and turn the key to the "on" position, just prior to starting the car.
2. Roll down the driver's side window (not required, but a good idea in case there's a
problem).
3. Exit the car and close the door.
4. With a second key, physically lock the doors (don't use a remote).
5. Take the first remote to be programmed, press one of the buttons and the lights will flash once. Wait 10 seconds and press the unlock button. The doors should unlock. That first transmitter is now programmed.
6. Lock the door again (physically) with the key, (not the remote).
7. Press one of the buttons twice, the lights will flash twice. Wait 10 seconds and press the unlock button. The doors should unlock. The second transmitter is now programmed.
For a third transmitter press the button 3 times and for a fourth press 4 times.
NOTE: if you have multiple remotes, follow all the steps above in sequence to complete the program for all the remotes you have. Do not stop in between to test the remotes or it won't work. After you complete the programming procedure for all the remotes within one session, then remove the valet key from the ignition, and then you can test the remotes.
