Understanding how to handle this simple maintenance task can save you time and a trip to the service center.

While Audi Hampton is always ready to assist with your automotive needs, including service appointments and key fob programming, we understand the desire for DIY solutions. This guide, brought to you by the experts at our service department, will walk you through the process of replacing your 2009 Audi Key Fob Battery. Whether you’re in Norfolk or closer to Williamsburg, knowing how to perform this task yourself ensures you’re never caught off guard by a dead key fob battery.

Replacing the Battery in Your 2009 Audi Key Fob

The process for replacing the battery in your 2009 Audi key fob is generally straightforward, though it can vary slightly depending on the specific type of key fob you have. Most 2009 Audi models utilize one of three key fob styles: the flip key fob, the smart keyless entry remote, or a standard remote. No matter which type you have, replacing the battery is a task you can confidently handle at home with a few simple tools and the correct replacement battery.

2009 Audi Flip Key Fob Battery Replacement

If your 2009 Audi uses a flip key fob, replacing the battery is a simple procedure. You’ll need a CR1620 battery, readily available at our parts center or most auto parts stores. Here’s how to replace the battery in your 2009 Audi flip key fob:

1. Open the Key Fob: Locate the small seam running along the side of your flip key fob. Gently insert a flathead screwdriver or a thin pry tool into this seam.

2. Separate the Casing: Carefully twist the screwdriver to separate the two halves of the key fob casing. Work your way around the seam until the case begins to open.

3. Identify Battery Side: Once the case is open, carefully set aside the half containing the metal flip key. Focus on the other half, which houses the battery.

4. Open the Remaining Half: You might find another smaller seam on this half of the casing. Use your screwdriver again to gently pry this section open, revealing the battery compartment.

5. Remove the Old Battery: Take note of the orientation of the battery (positive and negative sides). Carefully remove the CR1620 battery. A small tool can be helpful to gently nudge the battery out if it’s snug.

6. Insert the New Battery: Place the new CR1620 battery into the compartment, ensuring it’s oriented the same way as the old battery was removed (positive and negative sides matching).

7. Reassemble the Casing: Snap the two halves of the smaller casing back together until they click securely.

8. Final Reassembly: Bring the two main halves of the key fob casing back together and press firmly until they snap completely closed.

Note: In some cases, after a 2009 Audi key fob battery replacement, your car may not immediately recognize the key fob. If this happens, try inserting the key into the driver’s side door. Manually unlock and then lock the door using the key. Remove the key and press the “unlock” button on the fob. This can sometimes resynchronize the key fob with your Audi’s system.

2009 Audi Smart Keyless Entry Remote Battery Replacement

For 2009 Audi models equipped with a smart keyless entry remote, the battery replacement process is slightly different but still manageable. This type of 2009 Audi key fob requires a CR2032 battery. Here’s how to replace it:

1. Release the Metal Key: Locate the key release button, usually found on a chrome or metallic part of the fob. Press and hold this button to release the mechanical key from the fob.

2. Remove the Battery Holder: Once the metal key is removed, you’ll see an exposed plastic section where the key was housed. This is the battery holder. Grip this plastic piece firmly with your thumb and carefully pull it straight out from the key fob.

3. Access the Battery: With the battery holder removed, you’ll see the CR2032 battery.

4. Remove the Old Battery: Note the positive and negative orientation of the battery before removing it. Carefully remove the old CR2032 battery from the holder.

5. Install the New Battery: Place the new CR2032 battery into the holder, ensuring the positive and negative sides are correctly aligned.

6. Reinsert the Battery Holder: Slide the battery holder back into the key fob shell until it clicks or sits flush, ensuring it is securely in place.

7. Reinsert the Metal Key: Slide the metal key back into its slot until it clicks and locks into position.

2009 Audi Standard Remote Battery Replacement

Some 2009 Audi models might use a more basic remote style key fob. This type also typically uses a CR2032 battery. Here’s how to replace the battery in this 2009 Audi remote:

1. Open the Metal Key (if applicable): If your remote has a concealed metal key, open it as you would for manual door unlocking.

2. Locate the Back Cover Seam: Look for a small seam or indentation on the back cover of the key fob.

3. Pry Open the Back Cover: Using a small screwdriver or a similar tool, gently press into the seam to begin prying open the back cover. You might need to work your way around the edge to fully release the cover.

4. Remove the Back Cover: Once you’ve pried it open, carefully remove the back cover. You should now see the battery compartment.

5. Remove the Old Battery: Observe the orientation of the battery before removing it. Pull out the old CR2032 battery.

6. Install the New Battery: Place the new CR2032 battery into the compartment, matching the correct positive and negative terminals.

7. Replace the Back Cover: Carefully align the back cover and press it back onto the key fob until it snaps securely into place.

Programming Your 2009 Audi Key Fob After Battery Replacement

In most cases, simply replacing the battery in your 2009 Audi key fob will not require reprogramming. The key fob should resume normal function immediately. However, if you encounter issues after replacing the battery, such as the car not responding to the remote commands, you might need to resynchronize or reprogram your key fob.

For resynchronization, the method described earlier for the flip key (manual door lock/unlock with the physical key) can sometimes be effective for other types of 2009 Audi key fobs as well.

If you need to attempt a more formal programming procedure for your existing 2009 Audi key fob, you can try the following steps:

1. Enter the Vehicle: Get inside your 2009 Audi and close all doors.

2. Insert Key and Turn to “On”: Insert your key into the ignition. Turn the ignition to the “ON” position (just before starting the engine).

3. Press and Hold “Unlock”: Press and hold the “unlock” button on your key fob.

4. Turn Key to “Off” and Remove: While still holding the “unlock” button, turn the ignition key back to the “OFF” position and then remove the key from the ignition. Release the “unlock” button.

5. Test the Fob: Test the key fob functions (lock, unlock, panic button) to see if it’s now working correctly.

Note: Programming new or additional key fobs for your 2009 Audi often requires specialized equipment and procedures that are best handled by trained technicians. If you are having trouble programming your existing key fob after battery replacement, or if you need a new key fob programmed, it is recommended to visit our Audi Hampton dealership for professional assistance.
