Is your Audi key fob failing to lock or unlock your car? Don’t worry, you’re likely just dealing with a dead battery.

This guide from keyfobx.com, your trusted auto repair experts, will walk you through the process for various Audi key fob types, ensuring you can get back to conveniently accessing your vehicle.

Changing Battery on Audi Remote Key Fob

If you have an Audi remote key fob, follow these simple steps to replace its battery:

1. Flip Out the Metal Key: Begin by pressing the button to release and flip out the metal emergency key blade from your Audi key fob.

2. Locate the Black Cover and Press: Identify the small black cover, usually located near the key ring attachment. Use a small screwdriver or a similar tool to gently press this black cover.

3. Pop Open the Back Cover: While pressing the black cover, use your fingers or the screwdriver to carefully pry and pop off the back cover of the key fob. You might find a small notch or seam to help you get started.

4. Remove the Back Cover and Find the Battery: Once the back cover is removed, you’ll see the battery compartment inside the fob.

5. Take Out the Old Battery: Carefully remove the old battery. Note the battery type and polarity (+/-) for correct replacement. The Audi remote key fob typically uses a CR2032 battery.

6. Insert the New CR2032 Battery: Place the new CR2032 battery into the compartment, ensuring the polarity matches the markings in the fob.

7. Reattach the Back Cover: Snap the back cover back onto the fob until it is securely closed.

Changing Battery on Audi Smart Keyless Entry Remote Battery

For Audi models with a smart keyless entry remote, the battery replacement is slightly different:

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

2. Remove Battery Holder Cover: After removing the metal key, you will see exposed plastic that is the battery holder cover. Carefully pry off or slide this plastic cover to access the battery.

3. Take Out the Old Battery: Remove the old battery from the battery holder. Again, take note of the battery type, which is usually a CR2032 for Audi smart keys.

4. Insert New CR2032 Battery: Place the new CR2032 battery into the battery holder in the same orientation as the old one.

5. Reattach Battery Holder Cover: Put the plastic battery holder cover back onto the fob shell, ensuring it clicks or slides securely into place.

6. Reinsert Metal Key: Slide the metal key blade back into its slot in the fob shell until it locks in place.

Changing Battery on Audi Flip Key Battery

If your Audi uses a flip key, here’s how to change its battery:

1. Separate the Fob Case: Use a flathead screwdriver to gently pry open the flip key fob case. Carefully insert the screwdriver into the seam and twist to separate the case into two halves.

2. Set Aside Key Side: Set aside the half of the fob that contains the flip metal key. You will be working with the other half for battery replacement.

3. Separate the Shell to Access Battery: On the remaining half, use the screwdriver again to carefully separate the shell and expose the battery compartment.

4. Remove the Old Battery: Take out the old battery. Audi flip keys often use a CR1620 battery. Note the type before removal to ensure you get the correct replacement.

5. Insert New CR1620 Battery: Insert the new CR1620 battery into the battery compartment, matching the correct polarity.

6. Snap Shell Back Together: Press the shell back together until you hear a click or snap, indicating it is securely closed.

7. Reassemble Key Fob Halves: Bring the two halves of the key fob back together and press them firmly until they snap securely, reassembling the key fob.
