Audi A3 Key Fob Battery Replacement Guide
The battery replacement procedure for your audi a3 key fob can vary slightly depending on the year and specific model. While your owner’s manual is always the best resource for precise instructions, we’ve outlined the general steps for the most common Audi key fob styles found with the A3. Understanding your key type is the first step to a successful audi a3 key fob battery change.
Replacing the Battery in an Older Audi A3 Flip Key Fob
If your Audi A3 uses an older style flip key, here’s how to replace the battery:
- Identify the Battery Type: Older Audi flip keys typically require two 1620 batteries. Make sure you have these readily available before you begin.
- Open the Key Fob: Carefully use a flathead screwdriver to gently separate the two halves of the key fob casing. Insert the screwdriver into the seam and twist gently.
- Locate the Battery Cover: The half of the fob that doesn’t contain the flip key mechanism will have a separate battery cover.
- Remove the Battery Cover: Again, using your flathead screwdriver, carefully pry open the battery cover. There might be a small notch to help you get started.
- Replace the Batteries: Remove the old 1620 batteries. Take note of how they are positioned (+ and – sides). Install the new 1620 batteries in the same orientation.
- Reassemble the Key Fob: Snap the battery cover back into place. Then, carefully align the two halves of the key fob and press them firmly together until they click shut.
Changing the Battery in a Newer Audi A3 Flip Key Fob
Newer Audi A3 models, and some older ones, might use a different style of flip key. Here’s the battery replacement process for these:
- Battery Type: You’ll need a CR2032 battery for this type of audi a3 key fob battery replacement.
- 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.
- Open the Battery Cover: Insert a small flathead screwdriver into the notch. Gently twist or pry 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 and install the new one. Ensure the positive (+) side of the battery is facing upwards.
- Close the Key Fob: Carefully align the battery cover back onto the key fob. Make sure the plastic notches are correctly lined up before pressing it firmly until it snaps securely into place.

For Audi A3 models equipped with a smart key or keyless entry remote, the battery replacement steps are as follows:

- Remove the Metal Key Blade: Locate the release mechanism (usually a small button or slider) to remove the metal emergency key blade from the smart key fob.
- Locate the Notch: Look for a small notch where the metal key blade was located.
- Open the Fob Shell: Insert a flathead screwdriver into the notch, angling it towards the middle of the key fob.
- Pry Open the Casing: Carefully rotate the screwdriver to gently pry open the key fob shell. It should pop open along the seam.
