Gathering Your Supplies
To change your key fob battery, you’ll need a few simple supplies:
- A new key fob battery: Check your owner’s manual for the specific battery type required for your Audi A3 model. Most Audi A3 key fobs use a CR2032 battery.

- A small Phillips head screwdriver: This might be necessary for some models, depending on the key fob design.
Locating the Battery Compartment
The battery compartment on your Audi A3 key fob is usually located on the back of the fob.

2. Keyless Entry Key Fob: Depending on the model, the battery compartment may be hidden behind a small cover or a button.
Opening the Key Fob

Once the new battery is in place, close the key fob by pressing the two halves together. Make sure the key fob clicks shut securely.
Testing the New Battery
To ensure the new battery is working properly, test the key fob by:
1. Unlocking and locking the car doors: Press the unlock and lock buttons on the key fob to make sure they’re working.
