Step-by-Step Guide: Audi Remote Key Fob Battery Replacement

If you have an Audi remote key, replacing its battery is a breeze with these simple steps. This type of fob usually has a flip-out metal key. Here’s how to get it done:

1. Flip Open the Metal Key: Begin by pressing the button to release and flip out the metal key blade, just like you would if you were going to manually unlock your car door. This will give you access to the key fob casing.

2. Locate the Black Cover and Press: Look for a small black cover, often near where the key blade flips out. You’ll need a small screwdriver or a similar tool to gently press this cover. This action usually releases a catch that secures the back of the fob.

3. Pop Off the Back Cover: Once you’ve pressed the black cover, you should be able to use your fingernail or the edge of the screwdriver to gently pop up and remove the back cover of the key fob.

4. Identify and Remove the Old Battery: With the back cover removed, you’ll see the battery compartment. Note the orientation of the battery before carefully taking out the old battery. Audi remote key fobs typically use a CR2032 battery.

5. Insert the New CR2032 Battery: Take your new CR2032 battery and insert it into the battery compartment. Make sure the positive (+) side of the battery is facing the correct way, usually upwards.

6. Reattach the Back Cover: Carefully place the back cover back onto the fob. Press firmly until it snaps securely back into place.

7. Test Your Key Fob: Flip the metal key back in and test your key fob by trying to lock or unlock your Audi remotely. It should now be working perfectly.

Step-by-Step Guide: Audi Smart Keyless Entry Remote Battery Replacement

For Audi models equipped with a smart keyless entry remote, the process is slightly different but still easy to manage. These fobs often feature chrome accents and a more integrated design. Follow these steps:

1. Release and Remove the Metal Key Blade: Find the key release button, usually a small button or latch on the chrome part of the key fob. Press and hold this while gently pulling the metal key blade out of the fob.

2. Remove the Battery Holder Cover: Once the metal key blade is removed, you will see a small exposed plastic section which is the battery holder cover. You might need to use your fingernail or a small tool to carefully pry this plastic cover off.

3. Take Out the Old Battery: After removing the battery holder cover, the battery will be visible. Again, take note of the battery’s orientation before carefully removing it. Smart keyless entry remotes also commonly use a CR2032 battery.

4. Insert the New CR2032 Battery: Place the new CR2032 battery into the battery holder, ensuring the positive (+) side is facing the correct direction.

5. Reattach the Battery Holder Cover: Carefully align and snap the battery holder cover back into place on the fob. Make sure it is securely fastened.

6. Reinsert the Metal Key Blade: Slide the metal key blade back into its slot until it clicks into position, ensuring it is locked in place.

7. Test the Key Fob: Test your Audi smart keyless entry remote to confirm that it is now working correctly by attempting to remotely lock and unlock your vehicle.

Step-by-Step Guide: Audi Flip Key Battery Replacement

Audi flip keys, characterized by their key blade that flips out from the fob body, require a slightly different approach. Here’s how to replace the battery in this type of Audi key fob:

1. Separate the Fob Case: Use a flathead screwdriver to carefully pry open the case of the flip key fob. Insert the screwdriver into the seam running along the edge of the fob and gently twist to separate the case into two halves.

2. Set Aside the Flip Key Side: Take the half of the fob that contains the flip metal key and set it aside for now. You will be working with the other half to access the battery.

3. Separate the Shell of the Other Half: On the remaining half of the fob, you’ll need to further separate the shell to access the battery compartment. Use your screwdriver to gently pry apart this section.

4. Remove the Old Battery: Once the shell is open, you will see the battery. Note its orientation and then carefully remove the old battery. Audi flip keys typically use a CR1620 battery, which is slightly thinner than a CR2032.

5. Insert the New CR1620 Battery: Insert the new CR1620 battery into the battery compartment, making sure the positive (+) side is correctly oriented.

6. Snap the Shell Back Together: Carefully press the shell back together until you hear a snap, ensuring it is firmly closed.

7. Reassemble the Key Fob Halves: Finally, align the two halves of the key fob case and press them back together until they snap securely, reassembling your Audi flip key.

8. Test Your Key Fob: Flip out the metal key and test the key fob buttons to ensure that it is now functioning properly and remotely controlling your Audi.
