Understanding Your Audi Key Fob Types
Before we get into the specifics of how to open an Audi key fob, it’s helpful to understand that Audi utilizes a few different key fob designs, particularly across older and newer models. While the core function remains the same – remote locking/unlocking and vehicle control – the way you access the battery compartment varies. Broadly, Audi key fobs can be categorized into:
- Older Flip Key Fobs: These are typically found in older Audi models and feature a physical key that flips out from the fob. They often have a more rectangular shape.
- Newer Flip Key Fobs: While still featuring a flip-out key, these newer versions have a sleeker design and often use a different battery type compared to their older counterparts.
- Smart Keyless Entry Remote Fobs: These modern fobs are keyless entry remotes, allowing for push-button start and keyless access. They often have a more rounded or oval shape and may include features like remote start.
Knowing which type of key fob you have is essential when learning how to open your Audi key fob correctly. Let’s explore the specific steps for each type.
How to Open Different Audi Key Fobs for Battery Replacement
The process for how to open an Audi key fob differs depending on the type you own. Below are step-by-step instructions for each of the common Audi key fob types. Remember to work in a clean, well-lit area and handle the delicate components with care.
Opening Older Audi Flip Key Fobs
This method applies to older Audi models with the flip key design.
-
Identify the Battery Type: Older Audi flip key fobs typically use two 1620 batteries. Have these ready before you begin.
-
Separate the Key Fob Halves: Using a flathead screwdriver, carefully insert the tip into the seam running along the side of the key fob. Gently twist the screwdriver to separate the two halves of the key fob casing.
-
Locate the Battery Cover: The half of the key fob without the flip key mechanism will have a separate battery cover.
-
Open the Battery Cover: Again, using your flathead screwdriver, carefully pry open the battery cover. There might be a small notch to help you get started.
-
Replace the Batteries: Remove the old 1620 batteries. Take note of the battery orientation (+ and – sides). Install the new 1620 batteries in the same orientation.
-
Reassemble: Snap the battery cover back into place. Then, carefully press the two halves of the key fob casing back together until they click securely.
Opening Newer Audi Flip Key Fobs
Newer Audi flip key fobs have a slightly different opening mechanism and use a different battery.
-
Get a CR2032 Battery: Newer models usually require a CR2032 battery. Ensure you have a new one on hand.
-
Flip Out the Metal Key: Press the key release button to flip out the metal emergency key blade from the fob.
-
Find the Notch: Look inside the key compartment where the metal key was housed. You’ll find a small notch.
-
Pop Open the Cover: Insert a small flathead screwdriver into this notch. Gently twist to pop open the battery cover.
-
Pry Off the Cover: Once popped open, gently pry the cover away from the back of the fob, near the keyring loop.
-
Battery Replacement: Remove the old CR2032 battery and replace it with the new one. Make sure the positive (+) side of the battery faces upwards.
-
Reattach the Cover: Carefully align the plastic notches and gently press the cover back onto the key fob until it clicks into place.
Opening Audi Smart Keyless Entry Remote Fobs
For Audi smart key fobs, the process is also distinct.
-
Obtain a CR2032 Battery: Smart key fobs typically use a CR2032 battery.
-
Remove the Metal Key Blade: Locate the release button (often a small sliding switch) on the key fob and remove the metal emergency key blade.
-
Identify the Notch: Look in the area where the metal key blade was removed. You’ll see a small notch or slot.
-
Use a Flathead Screwdriver: Insert a flathead screwdriver into the notch at an angle, pointing towards the center of the key fob.
-
Rotate to Open: Carefully rotate the screwdriver to gently pry and pop open the key fob shell.
-
Change the Battery: Remove the old CR2032 battery and install the new one, ensuring correct polarity.
-
Snap the Cover Back: Carefully align the two halves of the key fob shell and snap them firmly back together until they are securely closed.
Troubleshooting: What if Your Audi Key Fob Doesn’t Work After Battery Replacement?
Occasionally, after replacing the battery, your Audi might not immediately recognize the key fob. Don’t worry; this is sometimes easily resolved. Here’s a simple reinitialization procedure you can try:
- Manual Door Lock: Insert the metal key blade into the driver’s side door lock.
- Manual Lock/Unlock: Manually use the key to unlock and then lock the driver’s side door.
- Unlock Button Press: Remove the key from the door and press the “unlock” button on your key fob.
This process often resynchronizes the key fob with your Audi’s system. If you continue to experience issues, it’s recommended to consult with Audi service professionals.
Audi Key Fob Battery Replacement Cost
The cost of replacing your Audi key fob battery is quite minimal if you do it yourself. A CR2032 or 1620 battery typically costs between $5 to $15, depending on the brand and retailer. Purchasing batteries in multi-packs can further reduce the individual battery cost.
