Are you experiencing issues with your 2012 Infiniti G37 key fob? Does it sometimes fail to lock or unlock your doors, or perhaps the remote start is no longer functioning reliably? One of the most common culprits for these problems is a low or dead battery in your key fob. Fortunately, replacing the battery in your Infiniti G37 key fob is a straightforward process that you can easily do yourself, saving you time and money compared to dealership service.
This guide will walk you through the simple steps to replace your 2012 Infiniti G37 key fob battery, ensuring your keyless entry system is back in top working order. We’ll also touch on when you might need a completely new key fob remote.
Step-by-Step Guide to Replacing Your Infiniti G37 Key Fob Battery
Before you begin, you’ll need a few items:
- A new CR2032 battery. This is the standard button cell battery used in most Infiniti key fobs and is readily available at most drugstores, supermarkets, and online retailers.
- A small flathead screwdriver or a similar tool to help open the key fob case.
- Your 2012 Infiniti G37 key fob.
Once you have these items, follow these steps:
-
Locate the Notch: On the back of your Infiniti G37 key fob, you’ll find a small notch or slot. This is where you’ll insert your flathead screwdriver to begin opening the case.
-
Carefully Pry Open the Case: Insert the tip of your flathead screwdriver into the notch. Gently twist or pry to separate the two halves of the key fob case. Be careful not to apply excessive force, as you could damage the plastic casing.
-
Access the Battery: Once the case is open, you’ll see the circuit board and the CR2032 battery. The battery is usually held in place by a small clip or within a battery holder.
-
Remove the Old Battery: Carefully remove the old battery. Note the orientation of the battery (+ side up or down) before removing it. This will ensure you install the new battery correctly. You may need to gently pry it out with your small screwdriver if it’s held tightly.
-
Insert the New Battery: Place the new CR2032 battery into the battery compartment, ensuring the correct orientation (usually the positive (+) side facing upwards). Push it gently until it’s securely in place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob case and press them firmly together until they snap back into place. Ensure the case is completely closed and there are no gaps.
-
Test Your Key Fob: Test your key fob by attempting to lock and unlock your Infiniti G37 remotely. The buttons should now be responsive, and your keyless entry should be working correctly.
When Might You Need a New Key Fob Remote?
While a battery replacement often resolves key fob issues, there are situations where you might need to consider purchasing a new key fob remote. These include:
- Physical Damage: If your key fob has been dropped, crushed, or exposed to moisture, the internal components may be damaged beyond repair.
- Lost Key Fob: If you’ve lost your key fob, replacing it is essential for security and vehicle access.
- Malfunctioning Buttons: If the buttons on your key fob are worn out or no longer function reliably even after a battery replacement, a new remote might be necessary.
- Range Issues Persist: If you continue to experience very short operating range even with a fresh battery, the issue could be with the key fob’s transmitter itself.
