How to Change Battery in Infiniti Key Fob

A dead key fob battery can be a major inconvenience, leaving you stranded and unable to start your Infiniti. Luckily, changing the battery in your Infiniti key fob is a quick and easy process that you can do yourself. This guide will provide you with step-by-step instructions, helpful tips, and answers to frequently asked questions to help you get back on the road in no time.

Identifying Your Infiniti Key Fob

Infiniti offers several different key fob designs depending on the model and year of your vehicle. While the process of changing the battery is generally similar, there might be slight variations. Before you begin, it’s essential to identify your specific key fob type.

Generally, you can categorize Infiniti key fobs into two main types:

  • Standard Key Fob: This type features a flip-out key blade and buttons integrated into the fob’s body.
  • Smart Key: This type, often referred to as a “keyless” entry system, typically has a sleeker design with separate buttons for lock, unlock, and panic functions.

Gathering the Necessary Tools

Before you start, gather a few simple tools to make the process smoother:

  • Small flat-head screwdriver: This will be used to pry open the key fob carefully.
  • New battery: The most common battery type for Infiniti key fobs is a CR2032 3V lithium coin battery. You can find these at most auto parts stores, electronics stores, and even grocery stores.
  • Optional: A small tray or container to keep the screws organized and prevent them from getting lost.

Step-by-Step Guide to Changing the Battery

Once you have your tools and new battery ready, follow these steps:

  1. Locate the battery compartment: Most Infiniti key fobs have a small slot or notch on the back or side that houses the battery compartment.
  2. Open the compartment: Carefully insert the flat-head screwdriver into the slot and gently pry open the cover. Avoid using excessive force, as this could damage the key fob.
  3. Remove the old battery: Once the compartment is open, gently remove the old battery. Note the battery’s orientation, as you’ll need to insert the new one the same way.
  4. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring it’s positioned correctly with the positive (+) side facing up or as indicated in the key fob’s battery compartment.
  5. Close the compartment: Align the cover of the battery compartment and press down firmly until you hear it snap back into place.
  6. Test the key fob: Check if the buttons are responsive by locking and unlocking your car doors or using the remote start function.

Troubleshooting Tips

If your key fob is still not working after replacing the battery, try these troubleshooting tips:

  • Check the battery orientation: Make sure the new battery is inserted correctly with the positive (+) and negative (-) terminals aligned properly.
  • Clean the battery contacts: Over time, battery contacts can accumulate dirt and grime, hindering connectivity. Use a cotton swab and a small amount of rubbing alcohol to clean the contacts on both the battery and the key fob.
  • Reprogram the key fob: In some cases, you might need to reprogram the key fob to your Infiniti after changing the battery. Consult your owner’s manual for specific instructions on how to do this.

When to Seek Professional Help

While changing the battery in your Infiniti key fob is usually a straightforward process, there are instances where seeking professional help is advisable:

  • Physical damage: If your key fob is physically damaged, such as having a cracked casing or broken buttons, it’s best to contact an authorized Infiniti dealer or a qualified automotive locksmith for repair or replacement.
  • Programming issues: If you are unable to reprogram your key fob after replacing the battery or suspect other programming-related problems, an authorized dealer or a specialized automotive locksmith can help.
