Lost your key fob or need to reprogram your 2000 Audi A4 remote? Don’t worry, you might be able to handle it yourself! This guide, designed for 2000 Audi A4 owners, will walk you through the steps to program your key fob, potentially saving you a trip to the dealership. Before you begin, ensure you have the correct FCC ID remote and that your remote batteries are in good condition. Let’s get started with clearing the memory channels in your car, which is essential before programming.
Clearing Memory Positions
Your Audi A4 has memory channels for key fobs, and clearing these is the first step to ensure successful programming. Here’s how to clear the memory positions:
- Ignition On: Insert one of your existing keys into the ignition and switch the ignition on.
- Lock the Door: Exit the vehicle and manually lock the driver’s side door using your second key from the outside.
- Press “Unlock” Button: On the remote transmitter key you intend to program, press the “unlock” button five times in rapid succession, within one-second intervals. You should observe the emergency flashers and/or hear the anti-theft system horn confirm each button press. This feedback indicates that the car is registering your input.
- Confirm Memory Clear: Wait for 6 seconds after the initial presses, and then press the “unlock” button on the remote transmitter key one more time to confirm the memory positions are cleared. At this point, the central locking system should remain locked, indicating successful clearing. If the door unlocks, repeat the clearing process.
- Ignition Off: Switch the ignition off and remove the key.
- Ready for Coding: Now, your Audi A4 is ready to have up to four keys coded to its system.
Coding Procedure
With the memory cleared, you can now proceed to code your key fob to your 2000 Audi A4. Remember, you’ll need two keys for this procedure as well. Ensure the keys you are coding are assigned to free memory slots to avoid overwriting previously programmed remotes.
- Ignition On: Insert an existing, working key into the ignition and switch the ignition on.
- Lock with Key to be Coded: Get out of the car and lock the driver’s door from the outside using the key fob you are currently coding.
- Press “Unlock” for Memory Slot: Within 5 seconds of locking the door, press the “unlock” button on the remote transmitter. Press it enough times to reach the desired memory position. For example, press twice for memory slot 2. Each press should be confirmed by the emergency flashers or anti-theft horn.
- Wait and Confirm: Wait for 5 seconds after pressing the “unlock” button for the memory slot. Then, press the “unlock” button one final time. The vehicle should unlock at this point, confirming the coding process is underway.
- Ignition Off and Test: Switch the ignition off and remove the key from the ignition. Now, test the function of the newly coded transmitter by pressing the lock and unlock buttons to ensure they are working correctly with your 2000 Audi A4’s central locking system.
Procedure for Re-coding an Existing Transmitter
If you have an existing transmitter that has stopped working or is malfunctioning, you can attempt to re-code it. This process is slightly different and can help re-establish the connection between your remote and your Audi A4.
- Press Remote Button: Press either the “lock” or “unlock” button on the remote transmitter that you wish to re-code.
- Manual Lock and Unlock: Within 30 seconds of pressing the remote button, manually lock and then unlock the driver’s side door using the key in the door lock cylinder. This action helps to synchronize the remote with the car’s system.
- Test Function: After performing the manual lock and unlock, check the function of the re-coded remote transmitter. Try locking and unlocking the car using the remote buttons to verify if the re-coding was successful.
By following these steps, you should be able to program or re-code your 2000 Audi A4 Key Fob. If you encounter any issues, double-check each step and ensure you are using a compatible key fob for your vehicle. If problems persist, it might be necessary to consult with a professional locksmith or Audi dealership for further assistance.
