Understanding Your Audi Key Fob: Opening Methods and Battery Replacement
Audi key fobs come in various designs, but the underlying principle for battery replacement remains similar across models. Knowing the type of key fob you have is essential for correctly opening your Audi key fob and accessing the battery compartment. While your Audi owner’s manual is the best resource for model-specific instructions, we’ve outlined the general procedures for three common Audi key fob styles:
Opening and Replacing the Battery in Older Audi Flip Key Fobs
For older Audi models, the flip key fob design is common. These fobs typically require two 1620 batteries. Here’s how to open and replace the battery:
- Battery Type: You’ll need two 1620 batteries for this type of Audi key fob.
- Separate the Fob Halves: Carefully insert a flathead screwdriver into the seam where the two halves of the key fob meet. Gently twist the screwdriver to separate the two halves.
- Locate the Battery Cover: Identify the battery cover on the half of the fob that doesn’t contain the flip key itself.
- Open the Battery Cover: Use the flathead screwdriver again to carefully pry open the battery cover. There’s usually a small notch to help you get started.
- Remove and Replace Batteries: Take out the old 1620 batteries. Install the new 1620 batteries, ensuring they are oriented correctly (usually positive side up, but check markings in the compartment).
- Reassemble: Snap the battery cover back into place until it’s secure.
- Close the Fob: Press the two halves of the key fob back together until they click shut.
Opening and Replacing the Battery in Newer Audi Flip Key Fobs
Newer Audi flip key fobs often use a single CR2032 battery. The opening process is slightly different from the older models:
- Battery Type: Obtain a new CR2032 battery.
- Flip Out the Metal Key: Press the key release button to flip out the metal emergency key blade.
- Find the Notch: Look for a small notch located inside the key compartment, now visible where the metal key was housed.
- Pry Open the Battery Cover: Insert a small flathead screwdriver into this notch. Gently twist to pop open the battery cover.
- Remove the Cover: Once popped open, carefully pry the cover away from the back of the fob, near the keyring loop.
- Replace the Battery: Remove the old CR2032 battery. Insert the new CR2032 battery, making sure the positive (+) side is facing upwards.
- Reattach the Cover: Carefully align the plastic notches and gently press the cover back onto the key fob until it clicks securely into place.
Opening and Replacing the Battery in Audi Smart Keyless Entry Remote Fobs
Audi smart keyless entry remote fobs, also using a CR2032 battery, have a different opening mechanism:
- Battery Type: You’ll need a CR2032 battery.
- Remove the Metal Key Blade: Locate the release button (usually a small slider or button) and remove the metal emergency key blade from the fob.
- Identify the Notch: Look for a small notch where the metal key blade was just removed.
- Open the Fob Shell: Insert a flathead screwdriver into this notch, angling it slightly towards the center of the key fob.
- Pry Open the Shell: Carefully rotate the screwdriver. This should pop open the key fob shell, separating the two halves.
- Battery Replacement: Remove the depleted CR2032 battery and replace it with a new one.
- Snap Back Together: Align the two halves of the key fob shell and firmly press them together until they snap securely closed.

Re-initializing Your Audi Key Fob After Battery Replacement
In most cases, after successfully opening your Audi key fob and replacing the battery, your car should recognize the key immediately. However, if you find that your Audi doesn’t recognize the key fob after the battery change, don’t panic. You might need to re-initialize the key. Here’s a simple re-initialization procedure you can try:
- Manual Door Lock: Insert the metal key blade into the driver’s side door lock.
- Manual Lock and Unlock: Manually use the key to unlock and then immediately lock the driver’s side door.
- Unlock Button Press: Remove the key from the door and press the “unlock” button on your key fob.
This process often resynchronizes the key fob with your Audi’s system. If you continue to experience issues, it’s best to consult with Audi service professionals.
