Understanding Infiniti Key Fob Batteries
Infiniti vehicles utilize a variety of key fob designs, each with its own unique battery type and replacement procedure. It’s crucial to identify the specific battery your key fob requires before attempting a replacement.
Common Infiniti Key Fob Battery Types
- CR2032: This is the most common battery type found in Infiniti key fobs. It’s a small, round battery with a 3-volt output.
- CR2025: Another common type, slightly smaller than the CR2032, also with a 3-volt output.
- Other Sizes: Some Infiniti models may use less common battery sizes. Always refer to your owner’s manual or consult an Infiniti dealership to determine the correct battery for your specific key fob.
Tools You’ll Need
Before you begin, gather the following tools to ensure a smooth and successful battery replacement:
- New Battery: Purchase a replacement battery of the correct type for your Infiniti key fob.
- Small Flathead Screwdriver: This will be used to pry open the key fob casing.
- Tweezers: Helpful for handling the small battery and its contacts.
Step-by-Step Guide to Changing the Battery
Now that you have the necessary tools and information, let’s walk through the process of replacing your Infiniti key fob battery:
1. Open the Key Fob
Locate the small seam or tab on the back of your key fob. Gently insert the tip of your flathead screwdriver into the seam and pry open the casing. Be careful not to apply excessive force, as you could damage the key fob.
2. Remove the Old Battery
Once the casing is open, you’ll see the old battery. Use your tweezers to carefully remove it from the compartment. Take note of the battery’s orientation, as the new battery must be inserted in the same way. (See Also: What Should I Do if My Car Battery Is Swollen? – Don’t Risk It!)

4. Close the Key Fob
Carefully align the two halves of the key fob casing and press them together firmly. Ensure that the seam or tab snaps securely into place.

Before putting your key fob away, test it to ensure that the new battery is working properly. Press the lock, unlock, and start buttons to confirm that they are functioning as expected.
Important Considerations
While changing a car key battery is generally a simple task, there are a few important considerations to keep in mind:
* **Battery Disposal:** Dispose of the old battery responsibly. Most auto parts stores and recycling centers accept used batteries.
* **Water Damage:** If your key fob has been exposed to water, allow it to dry completely before attempting a battery replacement. Water damage can cause electrical problems. (See Also: How to Get to Battery Spencer Without a Car? Easy Options)
