Is your 2009 Infiniti G37 key fob not working as reliably as it used to? You might be facing a common issue: a low battery. Replacing the battery in your Infiniti G37 key fob is a straightforward process that can save you time and money compared to dealership service. This guide will walk you through everything you need to know about your 2009 Infiniti G37 Key Fob Battery Replacement, ensuring you get back to enjoying the convenience of your keyless entry system.
Understanding Your 2009 Infiniti G37 Key Fob
The 2009 Infiniti G37 utilizes a sophisticated smart keyless entry remote, designed for both convenience and security. This remote is more than just a key; it’s a transmitter that communicates with your vehicle to perform several functions:
- Push-to-Start Ignition: If your G37 is equipped with push-button start, the key fob needs to be recognized by the system to start the engine.
- Remote Locking and Unlocking: Effortlessly lock and unlock your doors with the push of a button.
- Trunk Release: Open your trunk remotely for easy access.
- Panic Alarm: Activate the car alarm in emergency situations.
- Keyless Entry: Approach your vehicle, and the doors unlock automatically (if equipped with proximity keyless entry).
These features are powered by a small, replaceable battery inside the key fob. When this battery weakens, you might experience issues like reduced range, inconsistent operation, or complete failure of your key fob.
Identifying When to Replace Your Key Fob Battery
Several signs can indicate that it’s time for a 2009 Infiniti G37 key fob battery replacement:
- Reduced Range: You need to be closer to your car than usual for the remote to work.
- Intermittent Operation: The buttons work sometimes, but not consistently.
- Dashboard Warning Light: Some Infiniti models may display a warning message on the dashboard indicating a low key fob battery.
- No Response: The key fob completely stops working – no locking, unlocking, or trunk release.
If you’re experiencing any of these issues, replacing the battery is the first and easiest troubleshooting step.
Step-by-Step Guide to 2009 Infiniti G37 Key Fob Battery Replacement
Replacing the battery in your 2009 Infiniti G37 key fob is a simple DIY task. Here’s how to do it:
-
Identify the Battery Type: Your Infiniti G37 key fob uses a CR2032 battery. This is a common and readily available coin cell battery that you can purchase at most drugstores, supermarkets, and online retailers.
-
Gather Your Tools: You will need a small flathead screwdriver or a similar thin tool to open the key fob casing. A soft cloth can also be helpful to prevent scratches.
-
Locate the Notch: Examine your key fob. You’ll find a small notch or slot on the side or bottom of the casing.
-
Open the Key Fob: Carefully insert the flathead screwdriver into the notch and gently twist. This should pry open the key fob casing. Be gentle to avoid damaging the plastic.

-
Close the Key Fob Casing: Carefully snap the two halves of the key fob casing back together. Ensure they are firmly closed and aligned.
-
Test Your Key Fob: Test all the buttons on your key fob – lock, unlock, trunk release, and panic alarm – to ensure they are working correctly. If your G37 has push-button start, also test starting the engine.
What if Battery Replacement Doesn’t Solve the Issue?
If you’ve replaced the battery and your 2009 Infiniti G37 key fob still isn’t working, there might be other issues. Here are a few possibilities:
- Key Fob Damage: The internal components of your key fob might be damaged due to water, impact, or general wear and tear.
- Programming Issues: In rare cases, the key fob might lose its programming and need to be reprogrammed to your vehicle.
- Vehicle Issues: While less likely, problems with your car’s receiver system could also cause key fob malfunction.
In these situations, you might need a replacement key fob.
Considering a Replacement 2009 Infiniti G37 Key Fob
If battery replacement doesn’t fix your key fob problems, or if you need an additional key fob, purchasing a replacement is an option. When considering a replacement, keep these points in mind:
- OEM vs. Aftermarket: You can purchase genuine OEM (Original Equipment Manufacturer) key fobs from Infiniti dealerships or reputable online retailers specializing in OEM car remotes. Aftermarket options are also available, but ensure they are compatible with your 2009 Infiniti G37 and come from a trusted source.
- Programming is Required: A new Infiniti G37 key fob must be professionally programmed to your vehicle to work. This programming process involves syncing the new remote with your car’s immobilizer and keyless entry system.
- Programming Options:
- Dealership: Infiniti dealerships have the equipment and expertise to program new key fobs. This is generally the most expensive option.
- Automotive Locksmith: Many automotive locksmiths are equipped to program car key fobs, often at a more affordable price than dealerships. Look for locksmiths specializing in transponder keys and keyless entry systems.
- Emergency Key: Most replacement key fobs come with an uncut emergency insert key. This key also needs to be cut to match your car’s ignition and door locks. A locksmith or dealership can handle this.
