How to Replace the INFINITI Key Fob Battery

Don’t let a dead INFINITI key fob battery get in the way of your Overland Park commute! The INFINITI of Kansas City service center is here to help with an easy-to-follow, step-by-step guide to replace your INFINITI key battery and get back on the road in no time. Follow along below, and contact us if you have questions along the way!

What Type of Battery Does the INFINITI Key Fob Use?

Before we get started, you should ensure you have the right type of battery on-hand. The type of key fob will determine the battery required. The INFINITI Key Fob uses a CR2025 type battery, while a key fob made to work with the INFINITI Intelligent Key will require a CR2032 battery. An Olathe area INFINITI parts center can help you out if you’re having trouble finding the right battery for your model.

INFINITI Key Battery Replacement Steps

  1. Press the “release” tab located on the back of your key fob to remove the metal car key.
  2. After you’ve removed the metal key and the release tab, you need to open the small panel situated underneath. The INFINITI key fob battery housing should now be visible. To avoid scratching or damaging your key fob, we suggest using a flathead screwdriver with a bit of tape wrapped around the head.
  3. Replace the dead battery with a fresh battery, ensuring the positive (+) side is face-down in the fob.
  4. Reattach the small panel you removed earlier, then reinsert the metal key, as well as the release tab.
  5. Voila! You’re all set to head back out to Lees Summit.

INFINITI Key Fob Troubleshooting

Experiencing issues with your push-button start or your keyless entry remote? Take a look at our tips and tricks to help you troubleshoot the problem:

  • If your INFINITI won’t start, it may be due to a low key fob battery. Try holding the fob closer to the start button to reduce the energy required to send a signal.
  • If you still can’t start your car with push-button start, your key fob battery may not be to blame. Try replacing the INFINITI key battery first, but if the problem persists, you’ll need to schedule an appointment to have your vehicle’s battery inspected.
  • If your INFINITI key fob battery is dead, you can still start your vehicle and lock/unlock the doors using the metal key in the back of your key fob.
