This comprehensive guide will walk you through the process step-by-step, equipping you with the knowledge and confidence to tackle this common car maintenance task yourself. We’ll cover everything from identifying the correct battery type to safely opening your key fob and replacing the battery. By the end, you’ll be well-prepared to keep your Infiniti running smoothly and your key fob functioning flawlessly.
Identifying the Infiniti Key Fob Battery Type
Before you begin, it’s crucial to identify the correct battery type for your Infiniti key fob. Different Infiniti models may use varying battery sizes and types. The most common battery type used in Infiniti key fobs is the CR2032, a small, coin-shaped lithium battery. However, some models might use other sizes like CR2016 or CR2025.
Checking Your Owner’s Manual
The most reliable source of information is your Infiniti owner’s manual. It will clearly state the specific battery type and model number required for your key fob. Take a few minutes to locate this information in your manual before proceeding.
Inspecting the Battery Compartment
If you can’t find the information in your owner’s manual, you can often identify the battery type by inspecting the battery compartment itself. Carefully open the key fob (see the next section for instructions) and look at the battery. The battery’s size and model number will usually be printed on its surface.
Opening Your Infiniti Key Fob
Infiniti key fobs are designed to be relatively easy to open, but the specific method may vary depending on the model year and key fob design. Here are some common techniques:
Using a Small Tool
Many Infiniti key fobs have a small, hidden seam or gap along one edge. You can carefully insert a thin, flat tool, such as a plastic pry bar or a credit card, into this gap and gently pry open the key fob. Be extremely cautious not to use excessive force, as this could damage the key fob. (See Also: How to Test Car Battery with Innova 3300? Easy Steps)
Removing the Key Blade
Some Infiniti key fobs have a removable key blade. To open the fob, you’ll need to first remove the key blade by pressing a small button or lever on the side of the key fob. Once the key blade is removed, you can usually pry open the fob using a thin tool.
Searching for a Release Button
A few Infiniti key fob models have a dedicated release button on the back or side. Press this button to unlock the key fob, allowing you to separate the two halves.
Replacing the Infiniti Key Fob Battery
Once you’ve successfully opened your key fob, you’ll see the battery compartment. Remove the old battery by gently pulling it out. Insert the new battery, ensuring that the positive (+) and negative (-) terminals are aligned correctly. Refer to the battery’s packaging or the key fob’s diagram for the correct orientation.
Important Battery Handling Tips
- Handle the battery with clean hands to avoid contamination.
- Do not touch the battery terminals with your fingers.
- Dispose of the old battery properly. Lithium batteries should not be thrown in regular trash.
Reassembling and Testing Your Infiniti Key Fob
Carefully reassemble the key fob, ensuring that all parts are securely in place. Test the key fob by pressing the buttons to see if they are functioning properly. If the key fob doesn’t work, double-check the battery installation and make sure the terminals are making good contact.
