Have you ever pressed the button on your Nissan key fob only to be met with silence? A dead key fob battery is a common inconvenience, but thankfully, it’s a problem with a straightforward solution. You might be wondering, “How To Open Car Key Fob Nissan” to replace the battery. This guide will walk you through the process of accessing your Nissan, opening your key fob, and changing the battery, ensuring you’re back on the road in no time.
Even with a dead battery in your Nissan key fob, you can still access and operate your vehicle. Nissan thoughtfully includes a mechanical emergency key within the key fob itself. This allows you to unlock your car manually and start the engine, providing a temporary fix until you can replace the battery.
Accessing Your Nissan with a Dead Key Fob Battery
Before you can replace the battery, you’ll need to get into your Nissan. Here’s how to use the emergency key to unlock your vehicle and start the engine:
- Locate the Release Latch: Turn your Nissan key fob over to the back. You’ll find a small button or latch. Press and hold this release.
- Remove the Emergency Key: While pressing the latch, slide or pull out the emergency key. It’s usually located at the bottom of the key fob.
- Unlock Your Nissan Door: Insert the emergency key into the driver’s side door lock and turn it to unlock your Nissan, just like a traditional car key.
- Starting Your Nissan: Once inside, the starting method depends on whether your Nissan has a key fob port.
- 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 press the START/STOP button.
- Without a Key Fob Port: If you don’t have a port, step on the brake pedal or clutch and press the Nissan key fob directly against the START/STOP button. This allows the vehicle to detect the key fob’s signal despite the dead battery.
If you encounter any difficulties entering or starting your Nissan using these steps, it’s always best to seek professional assistance. Contact a Nissan dealership or a qualified automotive technician for help.
Identifying the Correct Battery for Your Nissan Key Fob
Knowing the right battery is crucial for a successful replacement. Nissan key fobs typically use common lithium coin cell batteries, but the specific type can vary depending on your Nissan model and year. Common battery types are CR2025 or CR2032 3V batteries.
The most reliable way to identify the correct battery is to open your key fob and check the markings on the old battery. Alternatively, your Nissan owner’s manual should specify the correct battery type for your key fob. You can purchase replacement batteries at most drugstores, hardware stores, auto parts stores, and online retailers. For convenience, you can also visit the parts center at your local Nissan dealership.
