Step-by-Step Guide to Open Your Audi Q7 Key Fob
Regardless of the specific Audi Q7 key fob you have, the goal is to carefully open the casing to access the battery compartment. Here are detailed instructions for each type:
Opening the Older Audi Flip Key Fob
If your Audi Q7 uses an older flip key, follow these steps to open it:
-
Locate a Flathead Screwdriver: You’ll need a small flathead screwdriver to gently pry open the key fob.
-
Separate the Key Fob Halves: Carefully insert the flathead screwdriver into the seam running along the key fob’s edge. Gently twist to separate the two halves of the key fob casing.

-
Battery Access: Once the cover is open, you’ll see the batteries. For older flip keys, these are usually two 1620 batteries.
Opening the Newer Audi Flip Key Fob
For newer Audi Q7 flip keys, the process is slightly different:
-
Flip Out the Metal Key Blade: Press the key release button to flip out the metal key blade.
-
Find the Notch: With the metal key flipped out, look inside the key compartment for a small notch.

-
Locate the Notch: Look for a small notch in the area where the metal key blade was removed.

-
Identify the Battery Type: Note the type of battery currently in your key fob (1620 or CR2032).
-
Obtain a New Battery: Purchase the correct replacement battery. CR2032 batteries are widely available at drugstores, supermarkets, and online retailers. 1620 batteries might be slightly less common but can also be found at similar locations.
-
Remove the Old Battery: Carefully remove the old battery, noting the orientation (positive side up or down).
-
Insert the New Battery: Install the new battery in the same orientation as the old one.
-
Reassemble the Key Fob: Carefully snap the battery cover and the key fob halves back together, ensuring they are securely closed.
What if Your Audi Q7 Key Fob Isn’t Recognized After Battery Replacement?
In most cases, your Audi Q7 key fob should work immediately after a battery replacement. However, if you find that your car doesn’t recognize the key, you may need to reinitialize it. Try this simple step:
- Manual Door Lock: Insert the metal key blade into the driver’s side door lock.
- Manual Lock/Unlock: Manually lock and then unlock the door using the key.
- Unlock Button: Remove the key and press the “unlock” button on your key fob.
This process often resynchronizes the key fob with your Audi Q7. If you still encounter issues, it’s best to consult with Audi service professionals.

The cost to replace your Audi Q7 key fob battery is minimal if you do it yourself. The batteries themselves typically range from $5 to $15, depending on the type and where you purchase them.
