Step-by-Step Guide to Replace Your Audi Key Fob Battery
The process to replace your Audi key fob battery can slightly vary depending on the specific model and year of your Audi. While your owner’s manual is always the best resource for precise instructions, we’ve outlined the general steps for three common types of Audi key fobs:
Replacing the Battery in Older Audi Flip Key Fobs
For older Audi models with the flip key design, follow these instructions to replace the battery:
- Identify the Battery Type: Older flip key fobs typically use two 1620 batteries. Ensure you have these readily available before starting.
- Separate the Key Fob Halves: Carefully use a flathead screwdriver to gently pry apart 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 key fob that does not contain the flip key mechanism will have a separate battery cover.
- Remove the Battery Cover: Again, using your flathead screwdriver, carefully detach the battery cover from the key fob. There might be a small notch to help you get started.
- Replace the Old Batteries: Remove the depleted 1620 batteries. Take note of the battery orientation (+/- sides) before removing the old ones. Install the new 1620 batteries in the same orientation.
- Reattach the Battery Cover: Snap the battery cover firmly back into its place on the key fob half. Ensure it is securely closed.
- Reassemble the Key Fob: Press the two halves of the key fob casing back together until they click securely.
Replacing the Battery in Newer Audi Flip Key Fobs
Newer Audi flip key fobs often utilize a different battery type and a slightly modified opening mechanism. Here’s how to replace the battery in these models:
- Acquire a CR2032 Battery: Newer Audi key fobs generally require a CR2032 battery. Make sure you have a new one on hand.
- Open the Metal Key: Locate the key release button on your key fob and flip out the metal emergency key blade.
- Find the Notch: With the metal key flipped open, look for a small notch inside the key compartment where the metal key was housed.
- Pry Open the Battery Cover: Insert a small flathead screwdriver into the notch. Gently twist or lever the screwdriver to pop open the battery cover.
- Remove the Cover Completely: Once the cover is slightly popped open, you should be able to gently pry it off completely from the back of the fob, near the keyring loop.
- Replace the CR2032 Battery: Remove the old CR2032 battery and insert the new one. Ensure the positive (+) side of the battery is facing upwards as you install it.
- Reattach the Battery Cover: Carefully align the plastic notches on the battery cover with their corresponding slots on the key fob. Gently press the cover back into place until it snaps shut.
Replacing the Battery in Audi Smart Keyless Entry Remote
For Audi models equipped with a smart keyless entry remote, the battery replacement process is as follows:
- Obtain a CR2032 Battery: Similar to newer flip key fobs, smart keyless entry remotes typically use a CR2032 battery.
- Remove the Metal Key Blade: Locate the release mechanism and remove the metal emergency key blade from the smart key fob shell.
- Identify the Notch: Look for a small notch in the area where the metal key blade was located. This is where you’ll insert your screwdriver.
- Pry Open the Fob Shell: Using a flathead screwdriver, insert it into the notch at an angle, pointing towards the center of the key fob.
- Rotate to Open: Gently rotate the screwdriver to carefully pop open the key fob shell. It may separate into two halves.
- Replace the CR2032 Battery: Remove the old CR2032 battery and replace it with a new one. Ensure correct polarity (positive side up).
- Snap the Cover Back On: Carefully align the two halves of the key fob shell and snap them firmly back together until they are securely closed.

What To Do If Your Audi Key Fob Isn’t Recognized After Battery Replacement?
In some cases, even after a successful battery replacement, your Audi might not immediately recognize the key fob. Don’t worry; this is sometimes normal. Before contacting our service experts, try reinitializing your key fob. Here’s a simple method you can attempt:
- Manual Door Lock: Insert the metal key blade into the driver’s side door lock.
- Manually Lock and Unlock: Use the key to manually unlock and then immediately lock the driver’s side door.
- Press Unlock Button: Remove the key from the door lock and press the “unlock” button on your key fob.
This reinitialization process often resolves the issue. If your key fob still isn’t working after trying this, it’s best to schedule a visit with our Audi service professionals for further assistance.
Audi Key Fob Battery Replacement Cost: DIY vs. Professional Service
