Identifying Your Audi Key Fob Type

Before you begin, it’s crucial to identify the type of key fob you have. Audi has used several different key fob designs over the years, and the battery replacement process can vary slightly. Older models may have a different procedure than newer, sleeker designs. Recognizing your key fob type will help you follow the correct instructions.

Common Audi Key Fob Types and Their Batteries

• Smart Key/Keyless Entry: These often use a CR2025 or CR2450 battery. Check your owner’s manual to be sure.
• Advanced Key: Some newer Audi models have advanced keys with more features. These may use less common battery types.

Gathering the Necessary Tools

Once you know your key fob type and the correct battery, gather your tools. You’ll need:

1. A small flathead screwdriver or a plastic pry tool. This is to open the key fob casing. Avoid using metal tools that can scratch or damage the fob.
2. The replacement battery. Make sure it’s the correct type and fresh.
3. Optionally, a small flashlight to help you see inside the key fob.

Step-by-Step Guide to Changing the Battery

Now, let’s get to the actual battery replacement process. Here’s a general guide, but remember to consult your owner’s manual for specific instructions related to your Audi model:

1. Locate the Release Button: Most Audi key fobs have a small release button or switch. This is usually on the side or back of the fob. Press this button to release the emergency key.
2. Use the Emergency Key: Insert the emergency key into the designated slot on the key fob. Gently twist or pry to separate the two halves of the key fob casing. Be careful not to apply too much force, which could break the casing.
3. Identify the Battery: Locate the battery inside the key fob. It’s usually held in place by a small clip or pressure.
4. Remove the Old Battery: Carefully pry the old battery out of its compartment using your flathead screwdriver or plastic pry tool. Be gentle to avoid damaging the contacts.
5. Insert the New Battery: Place the new battery into the compartment, making sure it’s oriented correctly (positive side up). You should hear a slight click when it’s securely in place. Double-check the orientation to avoid shorting the battery.
6. Reassemble the Key Fob: Align the two halves of the key fob casing and press them together until they snap shut. Test all the buttons to ensure they function correctly.
