Understanding Your 2016 Audi A5 Key Fob

The key fob is more than just a way to lock and unlock your car; it’s an integral part of your Audi A5’s security system. Understanding its functions and recognizing the signs of a dying battery can prevent unexpected lockouts. Common signs include decreased signal range, intermittent functionality, or the need to hold the fob closer to the car for it to work. Ignoring these signs can eventually lead to a completely unresponsive key fob, leaving you stranded.

Why Replace the Battery Yourself?

Replacing the key fob battery yourself is a quick and cost-effective alternative to visiting a dealership or automotive locksmith. With a few simple tools and this guide, you can easily complete the replacement in minutes.

Step-by-Step 2016 Audi A5 Key Fob Battery Replacement Guide

Here’s a detailed guide to replacing the battery in your 2016 Audi A5 key fob:

Locate the release button: On the side of your key fob, you’ll find a small release button. This button releases the emergency key blade.
Release the key blade: Press the release button and gently slide the key blade out.
Open the key fob: Use the edge of the key blade or a small flat-head screwdriver to carefully pry open the key fob casing along the seam created by the key blade slot. Be gentle to avoid damaging the casing.
Remove the old battery: Identify the old battery (typically a CR2032) and carefully remove it. Avoid using metal tools to prevent short-circuiting the battery.
Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces upwards, as indicated in the fob’s casing.
Reassemble the key fob: Align the two halves of the key fob casing and press them together until they snap securely shut.
Reinsert the key blade: Slide the emergency key blade back into its slot.
Test the key fob: Try locking and unlocking your car to verify the new battery is working correctly.

Troubleshooting

If your key fob still isn’t working after replacing the battery, consider these troubleshooting steps:

Check the battery: Ensure the new battery is correctly installed and isn’t damaged.
Resynchronize the key fob: Consult your owner’s manual for the specific resynchronization procedure for your 2016 Audi A5 model.
