A small flat-head screwdriver or a similar tool for prying open the key fob.
A fresh CR2032 battery. This is the most common type of battery used in Infiniti QX50 key fobs. It’s readily available at most electronics stores, pharmacies, and online.
A small soft cloth or cotton swab (optional) for cleaning the battery contacts.

Step-by-Step Guide to Changing the Battery

Now that you have everything you need, let’s get started with the replacement process. Follow these simple steps:

Locate the release button: On the side of your Infiniti QX50 key fob, you’ll find a small release button. Press this button to release the emergency key blade.
Pry open the key fob: Carefully insert the flat-head screwdriver into the slot where the emergency key was located. Gently pry open the key fob casing. You may hear a slight click as the two halves separate. Be careful not to damage the plastic.
Remove the old battery: Once the key fob is open, you’ll see the old CR2032 battery. Carefully remove the old battery using your screwdriver or fingernail.
Install the new battery: Insert the new CR2032 battery, making sure the positive (+) side faces upwards. Press it firmly into place.
Reassemble the key fob: Align the two halves of the key fob and press them together until they click securely back into place.
Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Troubleshooting Tips

If your key fob still isn’t working after replacing the battery, here are a few things you can try:

Check the battery orientation: Ensure the new battery is installed with the positive (+) side facing upwards.
Clean the battery contacts: Use a soft cloth or cotton swab to clean the battery contacts inside the key fob. This can help ensure a good connection.
Try reprogramming the key fob: In rare cases, you may need to reprogram your key fob after replacing the battery. Consult your owner’s manual for instructions on how to do this.
