How to Replace Key Fob Battery in Audi

A dead key fob battery can be a real pain, leaving you stranded and unable to unlock your Audi. Luckily, replacing the battery is a quick and easy fix you can do yourself at home. This guide will walk you through the simple steps of how to replace the key fob battery in your Audi, getting you back on the road in no time.

Identifying Your Audi Key Fob Type

Before you get started, it’s helpful to know what type of Audi key fob you have. There are two main types:

• Flip Key: This type of key fob features a key blade that flips out from the fob.
• Smart Key: This type of key fob is typically thicker and doesn’t have a visible key blade.

The process for replacing the battery is slightly different for each type, so knowing which one you have will ensure you follow the correct steps.

What You’ll Need

Gather these simple tools before beginning the battery replacement:

• Small flat-head screwdriver: This will be used to pry open the key fob casing.
• New CR2032 battery: This is the standard battery used in most Audi key fobs.

Pro Tip: “Always use a high-quality CR2032 battery for your Audi key fob. Low-quality batteries may leak or die quickly, leading to more frequent replacements,” advises John Miller, Senior Automotive Technician at CarCare Express.

Replacing the Battery in a Flip Key Fob

1. Locate the release button: Look for a small button or switch on the back of the key fob, usually near where the key blade folds out.
2. Release the key blade: Press the release button and gently pull the key blade away from the fob.
3. Open the key fob casing: Use the flat-head screwdriver to carefully pry open the casing along the seam where the key blade was attached.
4. Replace the battery: Remove the old battery and note the orientation (+/-). Insert the new CR2032 battery, making sure the positive (+) side is facing up.
5. Reassemble the key fob: Snap the casing back together, reinsert the key blade, and test your key fob to make sure it’s working.

Replacing the Battery in a Smart Key Fob

1. Locate the emergency key slot: Look for a small slot on the side or bottom of the key fob.
2. Release the emergency key blade: Insert the flat-head screwdriver into the emergency key slot and gently pry open the small cover. This will release the emergency key blade.
3. Open the key fob casing: Use the emergency key blade or the flat-head screwdriver to carefully pry open the casing along the seam.
4. Replace the battery: Remove the old battery and note the orientation (+/-). Insert the new CR2032 battery, ensuring the positive (+) side is facing up.
5. Reassemble the key fob: Snap the casing back together, reinsert the emergency key blade and cover, and test your key fob.
