Replacing your Audi Q7 key fob battery yourself can save you time and money. While professional service is always an option, understanding how to perform this simple maintenance task empowers you as an Audi owner. Let’s walk through the process to ensure your 2018 Audi Q7 key fob is working perfectly again.
Step-by-Step Guide to Replacing Your 2018 Audi Q7 Key Fob Battery
For the 2018 Audi Q7, you’ll likely have a newer style flip key fob or a smart keyless entry remote. Both are designed for relatively easy battery replacement. Here’s how to change the battery in each type:
Option 1: 2018 Audi Q7 Flip Key Fob Battery Replacement
If your 2018 Audi Q7 uses a flip key fob (where the metal key blade flips out), follow these instructions:
-
Acquire the Correct Battery: You’ll need a CR2032 battery. This is a common type of button cell battery readily available at most drugstores, supermarkets, and online retailers.
-
Flip Out the Metal Key: Press the key release button to flip out the metal key blade from your Audi Q7 key fob.
-
Locate the Notch: Look inside the key compartment where the metal key blade was housed. You’ll find a small notch.
-
Pry Open the Battery Cover: Carefully insert a small flathead screwdriver or a thin, sturdy tool into the notch. Gently twist or pry to pop open the battery cover.

-
Remove the Battery Cover: Once popped open, gently pry the cover away from the back of the key fob, near the keyring loop. It should detach easily.
-
Replace the Battery: Remove the old CR2032 battery. Take note of which side is facing up (positive side). Install the new CR2032 battery in the same orientation, ensuring the positive side is facing upwards.

-
Reattach the Cover: Carefully place the battery cover back onto the key fob. Ensure the plastic notches are aligned correctly before gently snapping it back into place. You should hear a click to confirm it’s securely closed.
Option 2: 2018 Audi Q7 Smart Keyless Entry Remote Battery Replacement
If your 2018 Audi Q7 uses a smart keyless entry remote (without a flip-out key, designed for keyless entry), the process is slightly different but still simple:
-
Obtain a CR2032 Battery: Again, you’ll need a fresh CR2032 battery.
-
Remove the Metal Key Blade: Locate the release button on your smart key fob and remove the metal key blade. This blade is a backup and slides out of the fob.
-
Find the Notch: Look in the area where the metal key blade was removed. You will see a small notch.
-
Pry Open the Fob Shell: Insert a flathead screwdriver into the notch, angling it slightly towards the middle of the key fob. Carefully rotate the screwdriver to gently pop open the key fob shell.

Replace the Battery: Open the fob shell and remove the old CR2032 battery. Note the orientation and replace it with a new CR2032 battery, ensuring the positive side is facing up.
-
Snap the Fob Shell Back Together: Carefully align the two halves of the key fob shell and gently snap them back together until they are securely closed.
Reinitializing Your 2018 Audi Q7 Key Fob (If Necessary)
In most cases, your 2018 Audi Q7 key fob should work immediately after a battery replacement. However, if your car doesn’t recognize the key fob, you might need to reinitialize it. Here’s a simple method to try:
- Manual Door Lock: Insert the metal key blade into the driver’s side door lock.
- Manually Lock and Unlock: Use the key to manually unlock and then lock the door.
- Press Unlock Button: Remove the key from the door and press the “unlock” button on your key fob.
This process often resynchronizes the key fob with your 2018 Audi Q7.
Cost of a 2018 Audi Q7 Key Fob Battery Replacement
The cost to replace your 2018 Audi Q7 key fob battery is minimal if you do it yourself. A CR2032 battery typically costs between $5 and $15, depending on the brand and retailer. If you prefer to have Audi Fletcher Jones or another service professional handle the replacement, labor costs will apply in addition to the battery cost. However, as you can see, replacing the battery yourself is a quick and cost-effective solution.
