Customer Question

Hi. I have an 2004 Audi Avant which has just started developing problems with the key fob. I just replaced the battery but there's no communication with the car so I assume its the fob itself. Any ideas before I go further..?

Hello

try this re-coding procedure

1. Switch Ignition ON and leave the key in the ignition.

2. Mechanically lock the vehicle using the Drivers door using a second key.

3. Using the remote control press the Unlock button once, and the horn will sound once.

4. Wait 6 seconds and press the unlock button once to activate the coding procedure. The remote control will now be programmed.

NOTE : When performing programming on additional remotes the procedure is the same, except you press the unlock button 2, 3 or 4 times for the different remote.

For example : If programming 2 remotes press the unlock button twice with a 1 second interval between each press, repeat for 3 and 4 remotes.

5. Switch Ignition OFF.

6. Remove key from ignition and check for operation.

7. The coding procedure can be repeated up to 4 times for additional remotes.

8. The ignition must be switched OFF between programming each remote control.
