Is your 1999 Audi A4 key fob malfunctioning, or did you get a new remote that needs programming? Reprogramming your key fob for your 1999 Audi A4 can often be done yourself, saving you a trip to the dealership. This guide provides a straightforward, step-by-step process to help you program your key fob and regain control over your vehicle’s locking system.
Understanding Key Fob Programming for Your 1999 Audi A4
Before you begin, ensure you have the correct FCC ID remote for your 1999 Audi A4. Also, double-check that the remote batteries are in good condition. The system in your Audi A4 has memory channels for key fobs, and sometimes clearing these channels is necessary before programming a new remote or re-programming an existing one. It’s always a good safety precaution to roll down your driver’s side window in case any issues arise during the programming process. This procedure is reported to work for models around the 1998 B5 A4, and it’s worth trying on your 1999 model.
Step-by-Step Programming Procedures
Here are the procedures for clearing the memory, coding a new key, and re-coding an existing transmitter for your 1999 Audi A4 key fob.
Clearing Memory Positions
This process clears the existing key fob memory channels in your Audi A4, allowing you to start fresh with programming.
- Switch ignition on: Use one of your existing keys to turn the ignition to the “on” position.
- Lock the door manually: Exit the vehicle and use a separate, physical key to manually lock the driver’s side door from the outside.
- Press “unlock” button repeatedly: On the remote transmitter key you intend to program, press the “unlock” button five times within one-second intervals. You should observe the emergency flashers or hear the anti-theft horn confirm each button press.
- Confirm memory clear: After waiting for 6 seconds, press the “unlock” button on the remote transmitter one more time to confirm the memory positions are cleared. At this point, the central locking system should not unlock the vehicle.
- Switch ignition off: Turn the ignition off and remove the key.
After completing these steps, the memory positions should be clear, and you can proceed to code up to four keys.
Key Coding Procedure
This procedure is for programming a new key fob to your 1999 Audi A4. You will need two keys for this process. Ensure that the keys being coded are programmed to free memory slots, otherwise, previously programmed remotes may no longer function.
- Switch ignition on: Use one of your existing keys to switch the ignition to the “on” position.
- Lock door with key to be coded: Exit the vehicle and use the key fob you are currently coding to manually lock the driver’s door from the outside.
- Press “unlock” to select memory position: Within 5 seconds of locking the door, press the “unlock” button on the remote transmitter enough times to reach the desired memory position. For instance, press the button twice for memory slot number 2. The emergency flashers or anti-theft horn will confirm each button press.
- Wait and confirm: Wait for 5 seconds. Then, press the “unlock” button one more time. The vehicle should unlock at this point.
- Switch ignition off and test: Switch the ignition off and remove the key. Test the functionality of the newly programmed transmitter.
Procedure for Re-coding an Existing Transmitter
If you have an existing key fob that has stopped working or needs to be re-synced, follow this procedure:
- Press button on remote: Press either the “lock” or “unlock” button on the remote transmitter.
- Lock and unlock manually: Within 30 seconds of pressing the remote button, use the physical key in the driver’s side door lock to manually lock and then unlock the vehicle.
- Test function: Check the function of the re-coded remote transmitter to ensure it is working correctly.
Conclusion
Programming your 1999 Audi A4 key fob can be a DIY task, saving you time and money. By following these step-by-step instructions, you should be able to successfully program your key fob and regain convenient remote access to your vehicle. Always double-check your remote’s FCC ID and battery condition before starting the process. For more guides and information on key fob programming and car maintenance, visit keyfobprog.com.
