As a proud Infiniti QX80 owner, you appreciate luxury and convenience, and the intelligent key fob is a big part of that. Knowing how to maintain your key fob, especially when it comes to replacing the battery, is essential to avoid any unexpected hassles. If you’re wondering about the Infiniti Qx80 Key Fob Battery Size, you’ve come to the right place. This guide will walk you through everything you need to know to keep your QX80 key fob powered up and working perfectly.
Identifying the Correct Battery Size for Your Infiniti QX80 Key Fob
The good news is that replacing the battery in your Infiniti QX80 key fob is a straightforward process. And when it comes to battery size, Infiniti, including the QX80 model, commonly uses a CR2032 battery. This is a widely available and inexpensive button-cell battery that you can find at most drugstores, supermarkets, and online retailers.
While the CR2032 is the standard for most Infiniti key fobs, including the QX80, it’s always a good idea to double-check. You can confirm the battery type by:
- Checking your owner’s manual: Your Infiniti QX80 owner’s manual will have specific information about your key fob, including the battery type.
- Examining the old battery: Once you open your key fob (as described in the next section), you can simply look at the old battery. The battery type (likely CR2032) will be printed directly on it.
Using the correct battery size is crucial for optimal performance and to avoid damaging your key fob. A CR2032 battery provides the reliable power needed for your Infiniti QX80 key fob to communicate with your vehicle effectively, ensuring features like remote start, locking/unlocking, and the panic button function as expected.
Step-by-Step Guide to Replacing Your Infiniti QX80 Key Fob Battery
Replacing the battery in your Infiniti QX80 key fob is a simple DIY task that you can usually complete in under 10 minutes. Here’s how:
Tools You’ll Need
- A new CR2032 battery: Make sure you have a fresh CR2032 battery ready.
- Small flathead screwdriver (or similar thin tool): A small screwdriver will help you open the key fob. To prevent scratches, you can wrap the tip in a small piece of tape.
Step-by-Step Instructions
-
Locate the Release Tab: On the back of your Infiniti QX80 key fob, you’ll find a small release tab.
-
Release the Mechanical Key: Press and hold the release tab. This will allow you to slide out and remove the mechanical key portion from the key fob.
-
Open the Key Fob Casing: Once the mechanical key is removed, you’ll see a small slot or seam where you can open the key fob casing. Gently insert your flathead screwdriver (or taped tool) into this slot and carefully pry the two halves of the key fob apart. Be gentle to avoid breaking the plastic casing.
-
Access the Battery Housing: After opening the casing, you’ll see the battery housing. The CR2032 battery will be visible.
-
Remove the Old Battery: Carefully remove the old CR2032 battery. You may be able to gently pry it out with your fingertip or the edge of your small screwdriver if needed. Take note of the battery’s orientation – usually, the positive (+) side faces upwards.
-
Insert the New Battery: Place the new CR2032 battery into the housing, ensuring the correct orientation (positive side up). Push it gently until it clicks into place.
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together until they are securely closed.
-
Reinsert the Mechanical Key: Slide the mechanical key back into its slot until it clicks and locks into place.
-
Test Your Key Fob: Test all the buttons on your key fob to ensure they are working correctly. Your Infiniti QX80 key fob should now be powered by its new battery and ready to use.

Troubleshooting Common Key Fob Issues
Even with a new battery, you might occasionally encounter issues with your Infiniti QX80 key fob. Here are a few troubleshooting tips:
- Proximity to Start Button: If your car doesn’t start immediately, especially after a battery replacement, try holding the key fob closer to the engine start button. Sometimes, the system needs a very close signal, particularly right after a battery change.
- Check Battery Orientation: Double-check that you inserted the new CR2032 battery with the correct polarity (positive side up). Incorrect orientation can prevent the key fob from working.
- Key Fob Reprogramming (Rare): In very rare cases, after a battery change, your key fob might need to be reprogrammed to your vehicle. This is uncommon, but if your key fob still doesn’t work after a battery replacement and troubleshooting, consult your Infiniti dealer.
When to Seek Professional Help
While battery replacement is usually the solution for a non-responsive key fob, there might be instances where the problem is more complex. If you continue to experience issues with your Infiniti QX80 key fob after replacing the battery, it’s best to seek professional assistance from a certified Infiniti technician.
Your local Infiniti dealership has trained technicians who can diagnose and resolve any key fob issues, whether it’s a deeper electronic problem with the fob itself or an issue with your vehicle’s receiver. They can also assist with key fob reprogramming or provide replacement key fobs if necessary.
Maintaining your Infiniti QX80 key fob is simple when you know the basics, including the correct CR2032 battery size. By following these steps, you can ensure your key fob remains reliable and convenient for years to come. And remember, your Infiniti service center is always there to help if you need expert assistance.
