Have you ever pressed the button on your Audi key fob and nothing happens? Or maybe you have to press it multiple times to lock or unlock your doors? A common culprit for these issues is a dead or dying battery in your key fob. Fortunately, replacing the battery in your Audi key fob is a straightforward process that you can easily do yourself at home. This guide from our experts at keyfobx.com will walk you through the steps to change your Audi key fob battery, ensuring you’re back on the road with a fully functional remote in no time.
Knowing how to replace your Audi key fob battery can save you time and a trip to the dealership. While there are a few different types of Audi key fobs, the battery replacement process is generally similar for each. Let’s dive into how to change the battery for the most common Audi key fob types.
Identifying Your Audi Key Fob Type and Battery
Before you begin, it’s helpful to identify which type of Audi key fob you have, as this will slightly alter the battery replacement steps. The most common types are the Audi Remote Key, the Audi Smart Keyless Entry Remote, and the Audi Flip Key. Don’t worry too much about pinpointing the exact name; the visual cues in the following sections will help you identify yours.
Most Audi key fobs use either a CR2032 or a CR1620 battery. You’ll need to know which battery your key fob requires before you start. Typically, you can find this information in your Audi owner’s manual, or by opening your key fob and checking the old battery. Having the correct replacement battery (CR2032 or CR1620) ready will make the process smooth and quick.
Step-by-Step Guide to Audi Key Fob Battery Replacement
Let’s explore the battery replacement process for each type of Audi key fob. Remember to work in a clean, well-lit area, and have a small flathead screwdriver or similar tool handy.
Replacing the Battery in an Audi Remote Key Fob
This type of key fob often features a metal key that flips out. Here’s how to change the battery:
-
Flip Out the Metal Key: Locate the button or mechanism to release the metal key and flip it out as if you were going to use it to manually unlock your door.
-
Access the Back Cover: Look for a small black cover, usually near where the key flips out. You might see a small slot or indentation.
-
Pry Open the Cover: Use your small screwdriver to gently press into the slot or indentation on the black cover. This should help to release the back cover.
-
Remove the Back Cover: Once released, carefully pop off the back cover of the key fob.
-
Locate and Remove the Old Battery: Inside the fob, you’ll see the battery. Note the orientation of the battery (positive side up or down). Gently remove the old battery.
-
Insert the New CR2032 Battery: Place the new CR2032 battery into the battery compartment, ensuring it’s in the same orientation as the old one.
-
Reattach the Back Cover: Carefully place the back cover back onto the fob and press until it clicks securely into place.
Replacing the Battery in an Audi Smart Keyless Entry Remote Fob
The Smart Keyless Entry Remote often has a chrome section and a removable metal key blade. Follow these steps:
-
Release the Metal Key Blade: On the chrome part of the key fob, find the key release button or latch. Press and hold it down with your thumb.
-
Remove the Metal Key Blade: While holding the release, pull the metal key blade out of the fob.
-
Remove the Battery Holder Cover: Where the metal key blade was, you’ll see an exposed plastic battery holder cover. Carefully pry this cover off.
-
Remove the Old Battery: The battery will now be visible. Take out the old battery, again noting its orientation.
-
Insert the New CR2032 Battery: Insert the new CR2032 battery into the holder in the correct orientation.
-
Reattach the Battery Holder Cover: Place the battery holder cover back onto the fob and press until it’s secure.
-
Reinsert the Metal Key Blade: Slide the metal key blade back into its slot until it clicks into place.
Replacing the Battery in an Audi Flip Key Fob
The Flip Key Fob is characterized by its case that splits into two halves. Here’s how to replace its battery:
-
Separate the Fob Case: Use a flat screwdriver to gently pry apart the case of the fob. Insert the screwdriver into the seam and twist gently to separate the two halves.
-
Set Aside the Key Side: Take the side of the fob that contains the flip metal key and set it aside for now. You’ll be working with the other half.
-
Separate the Shell (Other Half): On the other half of the fob, use your screwdriver to further separate the shell. This might involve prying at a seam or designated opening.
-
Remove the Old Battery: Once the shell is open, you’ll see the battery. Remove the old battery. This type of fob often uses a CR1620 battery.
-
Insert the New CR1620 Battery: Place the new CR1620 battery into the battery compartment in the correct orientation.
-
Snap the Shell Back Together: Press the shell pieces back together until you hear a snapping sound, indicating they are securely closed.
