Are you struggling to lock or unlock your Audi remotely? A common culprit is a dead battery in your key fob. Fortunately, replacing the battery in your Audi key fob is a straightforward task you can easily do yourself. This guide from the experts at keyfobx.com will walk you through the process of an Audi key fob battery replacement, ensuring you’re back to conveniently accessing your vehicle in no time.
Knowing how to replace your Audi key battery can save you a trip to the dealership and get you back on the road faster. While the specific steps may vary slightly depending on the type of Audi key you have, the general process is quite simple. Let’s dive into how to perform this DIY task effectively.
Identifying Your Audi Key Type
Before you begin, it’s helpful to identify which type of Audi key fob you have. While the battery replacement is similar across models, knowing your key type can make the process smoother. Audi keys generally fall into three categories:
- Audi Remote Key: This type typically has a metal key that flips out and a more rectangular shape.
- Audi Smart Keyless Entry Remote: Often sleeker and more modern, this key may feature keyless entry and push-button start functionality. It usually has a removable metal blade.
- Audi Flip Key: This key is characterized by a case that splits open into two halves, with the metal key flipping out from one side.
Once you’ve identified your key type, you can proceed with the appropriate battery replacement steps.
Tools You’ll Need
Gathering the necessary tools beforehand will make the battery replacement process quick and efficient. For most Audi key fob battery replacements, you will need:
- Small Flathead Screwdriver: Used for prying open the key fob case.
- New Battery: The most common batteries are CR2032 and CR1620 button cell batteries. Check your owner’s manual or the old battery to confirm the correct type for your key fob. It’s always a good idea to have a fresh, high-quality battery for optimal performance.
With your tools ready, let’s move on to the step-by-step instructions for each type of Audi key fob.
Step-by-Step Guide to Audi Key Fob Battery Replacement
No matter which Audi model you drive, from the A3 to the Q7, replacing your key fob battery is a similar process. Below are detailed instructions for each key type.
Replacing Battery in Audi Remote Key
This method is for the standard Audi remote key with a flip-out metal key.
- Flip Open the Metal Key: Begin by extending the metal key blade out fully. This will give you access to the key fob casing.
- Locate and Press the Cover Release: Look for a small black cover or indentation on the key fob, often near the base of the flip key. Use your small screwdriver to gently press this release.
- Pop Off the Back Cover: While pressing the release, use your fingers or the screwdriver to carefully pry and pop off the back cover of the key fob. It should detach relatively easily.
- Access the Battery: Once the back cover is removed, you’ll see the battery compartment inside the fob.
- Remove the Old Battery: Carefully take out the old battery. Note the orientation of the battery (positive and negative sides) before removing it. You might need to use the tip of your screwdriver to gently nudge it out.
- Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it’s in the same orientation as the old one. The positive (+) side usually faces upwards.
- Reattach the Back Cover: Align the back cover with the fob casing and press it firmly until it snaps back into place, securing the battery.
Replacing Battery in Audi Smart Keyless Entry Remote
Follow these steps for Audi smart keys with keyless entry.
- Release the Metal Key Blade: Locate the key release button, often a small chrome button on the key fob. Press and hold this button while you gently pull out the metal key blade from the fob.
- Remove the Battery Holder Cover: After removing the metal key, you’ll see an exposed plastic section that is the battery holder cover. Use your fingernail or the flathead screwdriver to carefully pry this cover off.
- Access the Battery Compartment: With the cover removed, the battery will be visible in its holder.
- Take Out the Old Battery: Gently remove the old CR2032 battery. Again, take note of its orientation before removal.
- Insert the New Battery: Place the new CR2032 battery into the battery holder, ensuring the correct polarity.
- Reattach the Battery Holder Cover: Place the battery holder cover back onto the fob and press until it clicks securely into position.
- Reinsert the Metal Key Blade: Slide the metal key blade back into its slot until it locks into place.
Replacing Battery in Audi Flip Key
Use these instructions for Audi flip keys that split into two halves.
- Separate the Key Fob Case: Insert the flat screwdriver into the seam running along the side of the key fob case. Gently twist the screwdriver to separate the case into two halves.
- Set Aside the Flip Key Side: Take the half of the fob that contains the flip metal key and set it aside. You’ll be working with the other half for battery replacement.
- Open the Battery Shell: On the remaining half, use your screwdriver again to carefully pry open the shell covering the battery compartment.
- Remove the Old Battery: Take out the old CR1620 battery. Note the orientation.
- Insert the New Battery: Place the new CR1620 battery into the compartment, ensuring it’s oriented correctly.
- Close the Battery Shell: Press the battery shell back together until you hear a snap, indicating it’s securely closed.
- Reassemble the Key Fob: Align the two halves of the key fob case and press them firmly together until they snap back into their original position.
Troubleshooting and Tips
While replacing your Audi key fob battery is generally straightforward, here are a few tips and troubleshooting steps:
- Double-Check Battery Type: Ensure you are using the correct battery type (CR2032 or CR1620) as specified for your key fob. Using the wrong battery type can lead to malfunction.
- Battery Orientation: Pay close attention to the battery orientation (+ and – sides) when replacing it. Incorrect orientation will prevent the key fob from working.
- Clean Contacts: If your key fob still doesn’t work after battery replacement, check the battery contacts in the fob for any dirt or corrosion. Clean them gently with a cotton swab if needed.
- Key Fob Not Working After Replacement?: In rare cases, after replacing the battery, your key fob might need to be resynchronized with your Audi. Consult your owner’s manual for instructions on key fob synchronization or contact your local Audi dealer.
