Is your 2019 Audi A3 key fob acting up? Before you panic and call the dealership, it might just be a dead battery. Don’t worry, replacing it is easier than you think! This guide will walk you through the process step-by-step.
Why Your Key Fob Battery Might Need Replacing
Just like any other battery, your Audi A3 key fob battery has a lifespan. Over time, it loses its ability to hold a charge. You might notice a few telltale signs like:
- Decreased range: Your car only unlocks when you’re standing right next to it.
- Intermittent functionality: The key fob works sometimes, but not others.
- Warning messages: Your Audi’s dashboard might display a “Key Battery Low” warning.
What You’ll Need
Before you begin, gather the following:
- A new CR2032 battery (available at most hardware and electronics stores)
- A small flat-head screwdriver or a plastic pry tool
How to Replace the Battery in Your 2019 Audi A3 Key Fob
Let’s get started!
- Locate the release button: On the back of your key fob, find the small, silver release button.
- Release the emergency key: Press the release button and gently slide out the emergency key blade.
- Open the key fob: Use the emergency key blade or a flat-head screwdriver to carefully pry open the key fob casing. There’s a small notch near the key ring hole that you can use as leverage.
- Remove the old battery: Identify the old CR2032 battery and gently pry it out. Note the positive (+) and negative (-) sides for the new battery placement.
- Install the new battery: Insert the new CR2032 battery, ensuring the positive (+) side faces up.
- Close the key fob: Align the two halves of the key fob casing and press them firmly together until you hear a click.
- Reinsert the emergency key: Slide the emergency key back into its slot.
- Test the key fob: Try locking and unlocking your Audi A3 to make sure the new battery is working.
Expert Tip from John Miller, Senior Automotive Technician: “When prying open the key fob, be gentle! Applying too much force can damage the casing. If you’re unsure, consider watching a video tutorial online or consulting your owner’s manual.”
