Have you ever pressed the unlock button on your Nissan key fob and been met with silence? It’s a frustrating moment, especially when you’re in a hurry. A dead key fob battery is a common issue for Nissan owners, but thankfully, it’s usually a simple fix. This guide, brought to you by the auto experts at keyfobprog.com, will walk you through everything you need to know about your Nissan key fob battery, from gaining access to your vehicle with a dead battery to replacing it yourself.
Accessing Your Nissan with a Dead Key Fob Battery
Even with a dead battery, your Nissan Intelligent Key is designed to get you in and on the road. Inside every Nissan key fob is a mechanical emergency key. This key allows you to manually unlock your car door and start the engine, giving you time to replace that dead battery. Here’s how to find and use it:
-
Locate the Emergency Key: On the back of your Nissan key fob, you’ll find a small button or latch. Press and hold this release to reveal and slide out the hidden emergency key.
-
Manually Unlock Your Door: Use the emergency key just like a traditional car key to unlock your Nissan door. Insert it into the driver’s side door lock cylinder and turn to unlock.
-
Starting Your Nissan: Once inside, starting your Nissan depends on whether your vehicle has a key fob port or not.
- With a Key Fob Port: Look for a designated slot or port on your steering column or dashboard. Insert the key fob into this port. Then, press the brake pedal (or clutch for manual transmissions) and push the START/STOP button.
- Without a Key Fob Port: If you don’t have a key fob port, step on the brake pedal (or clutch) and firmly press the Nissan key fob directly against the START/STOP ignition button.
If you’re still having trouble accessing or starting your Nissan, it’s always best to consult your owner’s manual or contact a Nissan service professional for assistance.
Identifying the Right Nissan Key Fob Battery Type
Knowing the correct battery for your Nissan key fob is crucial for a successful replacement. The battery type can vary depending on your specific Nissan model and year. While your owner’s manual is the definitive guide, there’s a quick way to find out.
The most reliable method is to open your key fob and check the dead battery itself. Common Nissan key fobs typically use coin cell batteries, often either a CR2025 or CR2032 3V battery. These codes are printed directly on the battery.
If you prefer to check before opening your fob, your Nissan owner’s manual will specify the exact battery type required for your key fob. You can purchase these widely available batteries at most drugstores, hardware stores, department stores, and auto parts retailers.
Step-by-Step Nissan Key Fob Battery Replacement
Replacing your Nissan key fob battery is a straightforward DIY task that can save you time and money. Here’s a simple 7-step guide to get your key fob working like new:
-
Remove the Emergency Key: Flip your Nissan key fob over and locate the release button or latch. Press it to detach and remove the emergency key.
-
Open the Key Fob Casing: Carefully pry open the key fob. Locate the small notch along the seam of the key fob casing. Insert a thin, flathead screwdriver or a plastic pry tool into this notch. Gently twist to separate the two halves of the key fob.
-
Remove the Old Battery: Once open, you’ll see the old battery. Take note of the battery’s orientation (+ side up or down) before removing it. You can use your fingertip or the small screwdriver to gently pry out the old battery.
-
Insert the New Battery: Place the new battery into the battery compartment, ensuring it’s in the correct orientation as you noted in the previous step. Push down gently until it’s securely in place.
-
Reassemble the Key Fob: Align the two halves of the key fob casing and press them firmly together until they snap or click back into place, ensuring a secure closure.
-
Replace the Emergency Key: Slide the emergency key back into its slot in the key fob until it clicks and is securely held.
-
Test Your Key Fob: Press the buttons on your key fob to test if it’s working correctly. The doors should lock and unlock, and the panic button should function.
Professional Nissan Key Fob Battery Service
While changing your Nissan key fob battery is easy to do yourself, if you prefer the convenience and assurance of professional service, schedule an appointment with a certified technician. At Tom Wood Auto Group and other Nissan service centers, trained professionals can quickly and efficiently replace your key fob battery, ensuring everything is done correctly. This is a great option if you’re unsure about DIY or simply prefer expert handling.
Nissan Key Fob Reprogramming: When is it Necessary?
It’s important to understand that replacing your key fob battery does not typically require reprogramming. Reprogramming is only necessary when you are introducing a new key fob to your vehicle, not when you’re simply replacing a battery in your existing key fob.
Nissan key fob reprogramming is a more complex procedure that involves syncing the new key fob with your car’s immobilizer system. This usually requires specialized equipment and is best performed at a Nissan dealership or a qualified automotive locksmith. If you suspect your key fob needs reprogramming (e.g., after purchasing a new key), it’s recommended to seek professional assistance.

Yes! Replacing a Nissan key fob battery is a very simple and quick DIY task. With a replacement battery and a small flathead screwdriver or pry tool, you can easily change the battery in under five minutes. Just follow the step-by-step guide outlined above.
