The Audi Key Fob is an important part of the car. It allows you to lock and unlock your vehicle, open the trunk, or start the engine. If it quits working for any reason, you will need to replace the battery so that it can work again. When this time comes, do you know how to change the battery in your key fob? In this blog post, we will guide and show you how to replace a battery in the key fob of an Audi TT model, as well as some other tips that are helpful when replacing batteries in the key fob.

How to replace the battery in your Audi key fob?

Like many other devices that use batteries, they can wear out over time. A key fob battery is among those on the list of things that need to be replaced. It is the best idea to replace your key fob battery every few years, as it can greatly decrease its usefulness and lifespan if you do not. To change your Audi TT Key Fob battery, follow these steps.

First, you need to flip open the physical key by pressing the small silver-like button on the key fob.

Second, gently remove the protective cover of the key fob by inserting a small screwdriver into the slot (where the metal key was) on one side of it and press it upward. This will open up the key fob cover a bit.

Third, use a flat head screwdriver to pry up the back cover at the end of the key fob to expose where the battery compartment is. If the flat head screwdriver is not available, you can either use the tip of a ball pen or a kitchen knife but be sure to wrap it in a thin cloth to avoid scratching the key fob casing.

Fourth, use the flat head screwdriver to pull out the old battery from the compartment. Remember how it was placed in the compartment so that you can later replace it correctly. Just remember to dispose of the old battery properly, as this type of battery is considered hazardous and can cause harm to the environment and those around you, especially to little children, if accidentally ingested.

Fifth, grab your new battery and insert it in the battery compartment. Make sure you follow the correct battery orientation for your key fob to work correctly. This key fob uses a CR2032 3V lithium battery which can be purchased at many local stores or online shops like Amazon.

Sixth and as the last step, close up the key fob by placing its back cover in place. All sides should snap together until you hear a distinct click. Make sure the back cover is securely shut before using your key fob again.

What are some tips to remember when changing the battery in your key fob?

In order for the key fob remote to work properly, it needs a fresh and new battery. Replacing the dead one with a new CR2032 coin cell will bring your key fob back to life and in good working order. Be sure that your replacement battery is not defective or leaked before installing it.

Before inserting the new battery, check the compartment if it's clean and dry. If you see there is dirt or corrosion, then clean it with a cotton swab before inserting the new battery.

If you are using a sharp or pointed tool in prying up the old battery, make sure to take extra care not to make a scratch or damage the battery compartment. You can also wrap the tip of the screwdriver with scotch tape to protect the battery compartment.

It's important to take your time and perform the process right because if done wrong can damage other components in your key fob.

What are the signs of a bad battery in the key fob?

The first sign of a bad battery is the key fob not working at all. If you press any buttons and nothing happens, then there's a great chance that your key fob has been drained from its power source. Other signs include the remote locking function no longer works. Lastly, if there is any crack in the battery pack of your key fob, then you need to replace it immediately.

In conclusion, replacing your Audi key fob battery is a simple task that you can do in the comfort of your own home. It is important to always inspect your key fob and replace the battery if there are signs of battery drain. A fob battery, in general, should last around three to four years before it needs to be changed, but it is ideal to replace the battery every other year to ensure optimal performance. Having a non-working Audi Key Fob can be very frustrating, but this guide should help you avoid that frustration by checking for signs of battery drain and replace the battery yourself before it dies out.
