1. Understanding Remote Matching for Your 2000 Audi A8
Remote matching, or key fob programming, is the process of synchronizing your key fob with your car’s immobilizer system. This allows you to remotely lock, unlock, and sometimes start your vehicle. For a 2000 Audi A8, this procedure is crucial when you replace a lost or damaged remote or add an additional one. Using VCDS (VAG-COM Diagnostic System) is a popular method among auto repair professionals.
1.1. Why Use VCDS for Remote Matching?
VCDS is a powerful diagnostic tool that provides direct access to your Audi’s control modules. It allows you to perform various functions, including remote matching, which can be more reliable and comprehensive than generic OBD-II scanners. According to Ross-Tech, a leading VCDS provider, “VCDS offers unparalleled access to VW/Audi vehicles, allowing for in-depth diagnostics and coding.”
1.2. Common Scenarios Requiring Remote Matching
- Lost or Stolen Key Fob: When a key fob is lost or stolen, matching a new one ensures that only authorized remotes can access your vehicle.
- Key Fob Replacement: If your key fob is damaged or malfunctioning, replacing it requires remote matching.
- Adding a Spare Key Fob: It’s always a good idea to have a spare key fob for emergencies.
- Battery Replacement: In some cases, replacing the battery in your key fob may require re-matching.
2. Essential Tools and Software
Before beginning the remote matching procedure, ensure you have the necessary tools and software.
- VCDS (VAG-COM Diagnostic System): This is the primary tool for communicating with your Audi’s control modules. Make sure you have the latest version installed on your laptop.
- Laptop: A Windows-based laptop with a USB port to connect the VCDS interface cable.
- VCDS Interface Cable: This cable connects your laptop to the OBD-II port in your Audi.
- Key Fobs: All key fobs you want to match to the car.
- Working Key: A working key that can start the car. This is needed for some procedures.
3. Step-by-Step Guide to 2000 Audi A8 Remote Matching with VCDS
Follow these detailed steps to match your 2000 Audi A8 remote using VCDS:
3.1. Preliminary Steps
- Connect VCDS: Plug the VCDS interface cable into the OBD-II port of your Audi A8 and connect it to your laptop.
- Turn on the Ignition: Insert a working key into the ignition and turn it to the “ON” position. Do not start the car.
- Launch VCDS: Open the VCDS software on your laptop.
- Select Control Module:
- Click on [Select].
- Choose either [46 – Cent. Conv.] (Central Convenience) or [35 – Cent. Locking] (Central Locking), depending on your vehicle’s configuration. Use the Ross-Tech Wiki to confirm which module is appropriate for your specific model.
3.2. Method 1: Adaptation Channel 01 (or 21)
This method is commonly used for many VW/Audi vehicles.
- Access Adaptation:
- Click on [Adaptation – 10].
- Enter channel “01” (or “21” for some Audi models).
- Click [Read].
- Identify Stored Remotes: The “Stored Value” field will display the number of currently matched remotes.
- Enter New Value:
- In the “New Value” field, enter the total number of keys you want to match, up to a maximum of 4 (including existing keys).
- Click [Test].
- Verify Test Value: Ensure the number in the “Test Value” field is correct.
- Save the Value: Click [Save].
- Match Remotes:
- Immediately press and hold the UNLOCK button on the first key fob for at least one second. The car may provide acknowledgement (lights flash, horn beep, etc.).
- Repeat this process for each additional key fob within 15 seconds.
- Test the Remotes: Turn off the ignition, remove the key, and test all the remotes to ensure they are working correctly.
3.3. Method 2: Measuring Blocks 003 (or 007)
If Method 1 doesn’t work, try this alternative:
- Insert Working Key: Insert a working key in the ignition and turn to the “ON” position (do not start the car).
- Select Control Module:
- Click on [Select].
- Choose either [46 – Cent. Conv.] or [35 – Cent. Locking].
- Access Measuring Blocks:
- Click on [Meas. Blocks – 08].
- Enter group “003” (or “007” for some vehicles).
- Click [Go!].
- Identify Matched Remotes: The value in field 2 shows how many remotes have been matched and in which memory positions. For example, “0001” indicates 1 transmitter in position 1.
- Lock the Car Manually: Lock the car from the outside using the new, unmatched key in the driver-side door lock. You may need to hold the key in the unlock position.
- Press Unlock Button: Press the UNLOCK button on the new key within 5 seconds, often enough to reach the next memory position. For example, if the value in field 2 was 0001, press the unlock button twice to put the new key in memory position 2.
- Wait and Unlock: Wait 5 seconds and press the UNLOCK button on the new key to unlock the door.
- Turn Off Ignition: Turn the ignition key to OFF and remove the old key.
- Test Remotes: Press LOCK and UNLOCK with the new key.
- Verify Matching:
- Insert the new key in the ignition and turn to the “ON” position (do not start the car).
- Click on [Select].
- Choose either [46 – Cent. Conv.] or [35 – Cent. Locking].
- Click on [Meas. Blocks – 08].
- Enter group “003”.
- Click [Go!].
- The value in field 2 should now indicate the new key is matched. For example, it might show 0011, indicating the old key is in position 1 and the new key in position 2.
3.4. Clearing Existing Matched Remotes (If Necessary)
In some cases, you may need to clear existing matched remotes before matching new ones.
- Select Control Module:
- Click on [Select].
- Choose either [46 – Cent. Conv.] or [35 – Cent. Locking].
- Access Adaptation:
- Click on [Adaptation – 10].
- Enter channel “00”.
- Click [Read].
- Save Zero Value:
- Click [Save].
- When the prompt asks if you are sure you want to save a value of 0 to Channel 00, click [Yes].
- Match New Remotes: After clearing the existing remotes, follow the appropriate procedure above to match all of the remotes.
