Let’s dive into how to replace your 2002 Audi key fob battery.
Step-by-Step 2002 Audi Key Fob Battery Replacement
The exact type of key fob your 2002 Audi uses might vary, but the battery replacement process is generally similar across models. Below are guides for the common types of Audi key fobs around the 2002 era. You’ll likely need either a CR1620 or CR2032 battery, which are readily available at most stores or our parts center.
Replacing the Battery in a 2002 Audi Flip Key Fob
If your 2002 Audi uses a flip key fob, follow these steps for a smooth battery replacement:
- Access the Casing: Gently use a flathead screwdriver to carefully separate the two halves of the key fob casing. Start at the point where the key flips out, as there’s often a small notch there.
- Separate the Halves: Once you’ve created a small opening, carefully work the screwdriver around the seam to fully separate the two halves of the fob. Be mindful not to apply excessive force to avoid damaging the plastic. Set aside the half containing the metal flip key.
- Open the Battery Compartment: With the other half in hand, you may need to use the screwdriver again to further separate this section and expose the battery compartment.
- Remove the Old Battery: Take out the old CR1620 battery. Pay close attention to the orientation – note which side is facing up (+) and which is down (-). This is crucial for correct installation of the new battery.
- Insert the New Battery: Place the new CR1620 battery into the compartment, ensuring the positive and negative sides are oriented correctly, just as the old battery was.
- Reassemble the Fob: Snap the two halves of the key fob casing back together. Press firmly until you hear or feel them click securely into place.
- Test Your Key Fob: Try using your 2002 Audi key fob to lock and unlock your car. If it doesn’t respond immediately, refer to the note below regarding resynchronization.
Note: If your 2002 Audi doesn’t immediately recognize the key fob after a battery change, don’t worry. Insert the physical key into the driver’s side door lock. Manually unlock and then lock the door using the key. Remove the key, and then press the “unlock” button on your fob. This process often resynchronizes the key fob with your Audi’s system.
Replacing the Battery in a 2002 Audi Smart Keyless Entry Remote
For 2002 Audi models equipped with a smart keyless entry remote, the battery replacement process is slightly different but still manageable:
- Release the Metal Key: Locate the key release button, usually a small button or lever on the chrome or metallic part of the fob. Press and hold this button to release and remove the metal emergency key from inside the fob.
- Access the Battery Holder: Once the metal key is removed, you’ll see exposed plastic where the key was housed. This is the battery holder. Grip this plastic section firmly with your thumb and carefully pull it straight out from the key fob.
- Remove the Old Battery: The battery, a CR2032 in this case, will now be visible in the battery holder. Remove the old battery, again noting the positive and negative orientation.
- Install the New Battery: Insert the new CR2032 battery into the battery holder, matching the correct positive and negative sides.
- Reinsert the Battery Holder: Slide the battery holder back into the key fob shell until it clicks or sits flush.
- Reinsert the Metal Key: Slide the metal emergency key back into its slot in the key fob until it clicks into place.
- Test the Remote: Test the functions of your 2002 Audi smart keyless entry remote to ensure the new battery is working.
Replacing the Battery in a 2002 Audi Standard Remote Key Fob
Some 2002 Audi models might use a simpler remote key fob. Here’s how to replace the battery:
- Open the Metal Key (if applicable): If your fob has a metal key that flips out or is stored within, open it fully.
- Locate the Back Cover Seam: Look for a seam or small notch on the back cover of the key fob.
- Pry Open the Back Cover: Use a small screwdriver to gently pry open the back cover at the identified seam or notch.
- Remove the Back Cover: Carefully detach the back cover. This should reveal the battery compartment.
- Remove the Old Battery: Take out the old CR2032 battery, remembering its orientation.
- Install the New Battery: Place the new CR2032 battery in the correct position.
- Reattach the Back Cover: Snap the back cover back onto the key fob until it’s securely closed.
- Test the Fob: Check if your 2002 Audi key fob is now functioning correctly.
Troubleshooting Your 2002 Audi Key Fob After Battery Replacement
After replacing your 2002 Audi key fob battery, in most cases, it should work immediately. However, if you encounter issues:
- Resynchronize: As mentioned earlier, try the resynchronization method using the physical key in the driver’s side door.
- Check Battery Orientation: Double-check that you inserted the new battery in the correct orientation (+ and – sides).
- Battery Type: Ensure you’ve used the correct battery type (CR1620 or CR2032).
- Clean Contacts: Inspect the battery contacts inside the fob. If they look dirty or corroded, gently clean them with a cotton swab and a bit of rubbing alcohol.
