How to Start a Nissan with a Dead Key Fob

Have you ever planned to leave for work in Live Oak or go out for the evening in Newberry just to discover your Nissan key fob battery is dead? If so, you may be wondering how to start a Nissan with a dead key fob. Learn how to unlock your Nissan and start it with a dead key fob battery! We will also show you what to do if you need a Nissan key fob battery change in this guide from the service team at Rountree Moore Nissan in Lake City!
Getting into Your Nissan
The first thing you’ll need to do is get into your Nissan vehicle. Although you may need a Nissan key fob replacement, you can still get into your car and go in the meantime.
- Flip the key fob over, then push the small release latch.
- Pull out the hidden emergency mechanical key from the bottom of the fob.
- Insert the key in the driver’s side door and unlock it to enter.
Starting Your Nissan With a Dead Key Fob
Once you’re in, you’ll need to know how to start your Nissan car, truck, or SUV. The method depends on whether your model features a designated key fob port or a standard push-button start:
- Vehicles with a Key Fob Port: Insert the dead fob directly into the port slot (usually located to the lower left of the steering wheel). Press the brake pedal or clutch, and press the START/STOP button.
- Vehicles without a Key Fob Port: Step on the brake pedal or clutch, and physically press the Nissan key fob directly against the START/STOP button while pushing it. The vehicle will detect the passive chip inside the fob even if the battery is completely flat.
Model-Specific Tips: Rogue, Sentra, Pathfinder, & Altima
While the steps above apply across the lineup, here is a quick reference for our most popular models frequently driven around Gainesville:
- Nissan Rogue & Altima: Most modern Rogue and Altima configurations do not feature a hidden port. You will almost always use the “fob-to-button” method, pressing the emblem side of the key fob directly against the start button.
- Nissan Sentra: If your Sentra has a dead key fob, ensure the vehicle is completely in Park. If the fob-to-button method doesn’t work on the first try, hold the fob against the button for up to 10 seconds to allow the vehicle to read the signal before pressing down.
- Nissan Pathfinder & Murano: For older generations of these SUVs, check the lower left dash assembly or inside the center console box for a hidden slot explicitly designed to hold your emergency key fob.
Nissan Key Fob Battery Change Step-by-Step
To avoid getting stranded again, you’ll want to perform a quick Nissan key fob battery replacement as soon as possible. Follow these steps:
- Remove the hidden emergency mechanical key from the fob.
- Use a small flathead screwdriver wrapped in a cloth to gently pry open the two halves of the key housing.
- Take note of the old battery position, remove it, and replace it with a fresh CR2025 battery, ensuring the negative (-) side faces up toward you.
- Snap the key fob housing back together firmly and test the buttons to ensure the key system fault light on your dashboard clears.
