Infiniti Key Fob Battery: A Comprehensive Guide to Troubleshooting and Replacement

Your Infiniti’s key fob is a marvel of modern automotive technology, providing seamless keyless entry and ignition. However, like all devices powered by batteries, it will eventually require a battery replacement. Recognizing the signs of a dying key fob battery and knowing how to replace it can save you time, money, and potential frustration. This comprehensive guide will equip you with the knowledge to handle Infiniti key fob battery issues confidently.

Recognizing a Dying Infiniti Key Fob Battery

Several telltale signs indicate your Infiniti key fob battery might be nearing its end. If you experience any of the following, it’s probably time to consider a replacement:

  • Decreased Range: The most noticeable sign is a reduced range for keyless entry and ignition. You might find yourself standing closer to your Infiniti than usual to lock or unlock the doors.
  • Intermittent Functioning: Your key fob might work intermittently, requiring multiple attempts to lock, unlock, or start your car.
  • Dim or No Response: A weak battery can also manifest as a dim or unresponsive key fob display.

What Battery Does an Infiniti Key Fob Take?

Infiniti key fobs typically use a CR2032 battery, a common lithium coin battery. These batteries are widely available at auto parts stores, electronics stores, and online retailers.

How to Change an Infiniti Key Fob Battery: A Step-by-Step Guide

Replacing the battery in your Infiniti key fob is a straightforward process that most car owners can handle with basic tools. Here’s a step-by-step guide:

  1. Locate the Release Button: Examine your Infiniti key fob for a small release button or switch. This button is usually located on the back or side of the fob.
  2. Release the Key Blade: Press the release button and gently slide out the emergency key blade from the fob.
  3. Separate the Fob Halves: Using a small flathead screwdriver or a similar tool, carefully pry open the key fob halves at the seam. You’ll find a small notch where you can insert the screwdriver.
  4. Identify and Remove the Battery: Inside the fob, you’ll see the CR2032 battery. Note its orientation before gently prying it out with the screwdriver or your fingernail.
  5. Install the New Battery: Insert the new CR2032 battery, ensuring it sits in the same orientation as the old one.
  6. Reassemble the Key Fob: Snap the two halves of the key fob back together until you hear a click, indicating they’re securely closed.
  7. Reinsert the Key Blade: Slide the emergency key blade back into its slot until it locks in place.
  8. Test the Key Fob: Verify that all key fob functions, including lock, unlock, and panic, are working correctly.

Important Tip: Handle the new battery by its edges to avoid transferring oils from your skin, which can potentially shorten its lifespan.

What to Do if Your Infiniti Key Fob Still Doesn’t Work

If you’ve replaced the battery but your Infiniti key fob still exhibits issues, there are a few additional troubleshooting steps you can take:

  • Reprogram the Key Fob: Sometimes, a battery replacement might require you to reprogram the key fob to your Infiniti. Refer to your owner’s manual for specific instructions, as the process can vary slightly between models.
  • Inspect for Damage: Carefully examine your key fob for any physical damage, such as cracks, water ingress, or worn-out buttons. Damage to the fob’s internal components might necessitate a replacement.
  • Consult a Professional: If troubleshooting efforts prove unsuccessful, it’s best to consult a qualified Infiniti dealership or an automotive locksmith specializing in key fob programming and repair.
