Identifying Your Audi A3 Key Fob Type
Before we begin, it’s helpful to identify the type of key fob you have for your Audi A3. While specific designs may vary slightly across Audi A3 model years, most fall into one of these general categories:
- Older Style Flip Key Fob: This type typically features a key that flips out from the fob.
- Newer Style Key Fob (Smart Key): These are often more streamlined and may have a removable physical key integrated within the fob itself.
Knowing your key fob type will help you pinpoint the exact steps for battery replacement, although the fundamental principles remain similar.
Step-by-Step Guide to Changing Your Audi A3 Key Fob Battery
Regardless of the specific style, changing the battery in your Audi A3 key fob is usually a simple procedure. You’ll generally need a small flathead screwdriver and a new CR2032 battery. Let’s break down the process for the most common Audi A3 key fob types:
Replacing the Battery in an Older Audi A3 Flip Key Fob
If your Audi A3 uses an older flip key style fob, follow these steps to replace the battery:
-
Gather Your Tools and Battery: You will need a small flathead screwdriver and two CR1620 batteries. Although the original article mentions 1620 batteries for older models, it’s crucial to verify the correct battery type for your specific Audi A3 key fob in your owner’s manual or by checking the old battery itself before purchasing replacements. Sometimes, even older models might use CR2032.
-
Open the Key Fob: Carefully inspect your flip key fob. You’ll typically find a seam running around the center of the fob. Use your flathead screwdriver to gently pry open the two halves of the key fob casing. Insert the screwdriver into the seam and twist gently to separate the halves.
-
Locate the Battery Compartment: Once the fob is open, identify the battery compartment. It’s usually covered by a small, separate cover within one half of the fob.
-
Remove the Battery Cover: Use your flathead screwdriver again to carefully detach the battery cover. There might be a small notch or clip you need to gently pry to release the cover.
-
Replace the Old Batteries: Remove the old 1620 batteries (or the type your fob uses). Note the orientation of the batteries (+ and – sides). Install the new batteries in the same orientation.
-
Reassemble the Key Fob: Snap the battery cover back into place. Align the two halves of the key fob casing and press them firmly together until they click securely, closing the fob.
Replacing the Battery in a Newer Audi A3 Key Fob (Smart Key)
For newer Audi A3 models with smart key fobs, the battery replacement process is slightly different:
-
Prepare Your Tools and Battery: You’ll need a new CR2032 battery and a small flathead screwdriver.
-
Remove the Emergency Key: Locate the small button or release catch on your key fob. Press and hold it to release the metal emergency key blade from the bottom of the fob. Set the metal key aside.
-
Access the Notch: Look inside the key compartment where you removed the metal key. You’ll find a small notch or slot.
-
Pry Open the Fob: Insert the tip of your flathead screwdriver into the notch. Gently twist the screwdriver to carefully pry open the key fob casing. The casing is usually designed to separate at this point.
-
Open the Casing Further: Once you’ve created a small opening at the notch, you can often use your fingers or the screwdriver to gently separate the two halves of the key fob completely. Work your way around the seam, carefully prying until the casing is open.
-
Replace the Battery: Locate the CR2032 battery inside. Remove the old battery, noting its orientation (positive side up). Install the new CR2032 battery in the same orientation.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they snap back into place securely. Ensure there are no gaps and the fob feels properly closed.
-
Reinsert the Emergency Key: Slide the metal emergency key blade back into its slot in the key fob until it clicks into place.
What to Do If Your Audi A3 Key Fob Isn’t Recognized
After successfully replacing the battery, your Audi A3 key fob should ideally work immediately. However, in some rare cases, the car might not recognize the key fob right away. If this happens, try the following re-initialization steps:
- Manual Door Lock Re-initialization: Insert the emergency key blade into the driver’s side door lock.
- Manually Lock and Unlock: Use the key to manually lock and then unlock the door.
- Press Unlock Button: Remove the key from the door lock and press the “unlock” button on your key fob.
This process often helps resynchronize the key fob with your Audi A3’s system. If you continue to experience issues, it’s advisable to contact our service experts at keyfobx.com or your local Audi dealer for further assistance. There might be a need for professional programming or diagnostics.
Audi A3 Key Fob Battery Replacement Cost
The cost to replace your Audi A3 key fob battery is minimal if you do it yourself. A CR2032 battery (or CR1620, depending on your fob) typically costs between $5 to $15, depending on the brand and retailer. You can find these batteries at most drugstores, supermarkets, auto parts stores, and online retailers.
