Is your 2012 Infiniti G37x key fob not working as reliably as it used to? You might be facing the common issue of a low battery. The key fob for your Infiniti G37x is a crucial part of your car’s keyless entry and security system, and keeping it powered is essential for smooth, everyday use. This guide will walk you through everything you need to know about your 2012 Infiniti G37x Key Fob Battery, from identifying the type of battery you need to understanding replacement and programming considerations.
Understanding Your Infiniti G37x Key Fob
The 2012 Infiniti G37x comes equipped with a sophisticated keyless entry remote, often referred to as a smart key or key fob. This remote offers convenient features like:
- Keyless Entry: Lock and unlock your doors and trunk with the push of a button.
- Push-to-Start Ignition: Start your vehicle’s engine without inserting a traditional key into the ignition.
- Panic Alarm: Activate a loud alarm system for emergencies or security concerns.
These features are powered by a small, replaceable battery inside the key fob. When this battery starts to weaken, you might notice a decrease in the range of your remote, or that you need to press the buttons multiple times for them to register.
Identifying the Correct Battery: CR2032
The battery you need for your 2012 Infiniti G37x key fob is a CR2032 battery. This is a widely available 3V lithium coin cell battery. You can find CR2032 batteries at most drug stores, supermarkets, electronics stores, and online retailers. It’s always a good idea to keep a spare CR2032 battery at home so you’re prepared when the time comes to replace it.

Step-by-Step Battery Replacement (General Guide)
While the original article doesn’t provide specific battery replacement steps, changing a CR2032 battery in most key fobs is a straightforward process. Here’s a general guide based on typical key fob designs:
- Locate the Emergency Key: Most key fobs have a small emergency key that slides out. Remove this key. This often reveals a small slot or opening.
- Open the Fob: Use the emergency key or a small flathead screwdriver to gently pry open the key fob casing at the slot you located. Be careful not to scratch or damage the plastic.
- Access the Battery: Once the fob is open, you’ll see the CR2032 battery. It might be held in place by small clips.
- Remove the Old Battery: Carefully remove the old battery. Note the orientation of the battery (+ side up or down) before removing it.
- Insert the New Battery: Install the new CR2032 battery, ensuring it’s in the correct orientation.
- Close the Fob: Snap the key fob casing back together until it’s securely closed.
- Test: Test the key fob buttons to ensure they are now working.
Important Note: Always refer to your Infiniti G37x owner’s manual for the most accurate and specific instructions for your vehicle’s key fob battery replacement. While the CR2032 battery is standard, the exact opening mechanism of your key fob might have slight variations.
Programming and Emergency Key Information
The product description mentions that the replacement remote “must be professionally programmed when received.” However, replacing the battery in your existing key fob should NOT require reprogramming. The programming is typically only needed when you are introducing a new, unprogrammed key fob to your vehicle.

The included emergency insert key is designed to manually unlock your car door in situations where the remote battery is dead or the keyless entry system is malfunctioning. If you purchase a new key fob (as described in the original article), the emergency key will need to be cut to match your vehicle’s ignition and door locks. This is a service typically offered by dealerships or locksmiths.
Where to Find Replacement Key Fobs and Batteries
If you need to replace the entire key fob, or simply need a new battery, you have a few options:
- Infiniti Dealership: Dealerships can provide genuine OEM key fobs and batteries. They can also handle programming and key cutting if needed.
- Automotive Locksmiths: Many automotive locksmiths specialize in key fob replacement, programming, and battery services, often at a lower cost than dealerships.
- Online Retailers: You can purchase replacement key fobs and CR2032 batteries online. Ensure you are buying from a reputable source.
Conclusion
Replacing the battery in your 2012 Infiniti G37x key fob is a simple maintenance task that can save you from the inconvenience of a non-functional remote. By using the correct CR2032 battery and following a few basic steps, you can keep your key fob working reliably for years to come. Remember to consult your owner’s manual for specific instructions and seek professional help if you encounter any issues or need to replace the entire key fob unit.
