Many car owners face this problem, and it’s often due to a simple issue – a dead battery in the car key. In this blog post, we’ll guide you through the process of changing a Nissan car key battery. This is an essential skill to have, especially if you’re a car owner who values convenience and independence.

Changing a car key battery is a relatively simple process that can be done at home with a few basic tools. However, it’s essential to follow the correct procedure to avoid damaging the key or the car’s locking system. In this post, we’ll cover everything you need to know, from identifying the type of battery to using the correct tools and techniques.

Understanding Your Nissan Car Key

Your Nissan car key is a complex device that contains a battery, a microchip, and a mechanical component. The battery is responsible for powering the key’s electronic functions, such as the remote locking and unlocking features. Over time, the battery can drain, causing the key to malfunction or stop working altogether.

To change the battery in your Nissan car key, you’ll need to identify the type of battery used in your key. The most common type of battery used in car keys is a CR2032 battery. This battery is a small, round battery with a diameter of 20mm and a thickness of 3.2mm.

Before you start, make sure you have the following tools and materials:

  • A CR2032 battery
  • A screwdriver (preferably a small, flathead screwdriver)
  • A pair of tweezers or a small tool for removing the battery
  • A new CR2032 battery (if the old one is dead)

Locating the Battery Compartment

The battery compartment is usually located on the back of the car key, near the key fob. To access the compartment, you’ll need to remove the key fob cover. This cover is usually held in place by a small screw or clip.

Use a screwdriver to remove the screw or clip that holds the key fob cover in place. Gently pry the cover open, taking care not to damage the surrounding plastic.

Once the cover is removed, you’ll see the battery compartment. This compartment is usually marked with a small symbol or label indicating the type of battery used.

Take a closer look at the battery compartment and identify the type of battery used in your key. If you’re unsure, consult your owner’s manual or contact a Nissan dealership for assistance.

Removing the Old Battery

Once you’ve identified the type of battery used in your key, you can proceed to remove the old battery. Use a pair of tweezers or a small tool to carefully pull out the battery from the compartment.

Be careful not to touch any of the electrical components in the key, as this can cause damage or short circuits.

Once the old battery is removed, take a moment to inspect the battery compartment and surrounding area for any signs of corrosion or damage. (See Also: How to Refurbish a Car Battery at Home? Save Money Now)

Installing the New Battery

Installing the new battery is a straightforward process that requires a few simple steps. Make sure you have the new CR2032 battery ready and follow these steps:

1. Take the new battery and align it with the battery compartment. Make sure the positive terminal (the side with the “+” symbol) is facing upwards.

2. Gently push the new battery into the compartment until it clicks into place. You may hear a slight click or feel a slight resistance as the battery settles into the compartment.

3. Once the new battery is in place, use a pair of tweezers or a small tool to secure it in the compartment. Make sure it’s seated properly and not loose.

4. Close the battery compartment and replace the key fob cover. Make sure the cover is securely fastened with the screw or clip.

5. Test the key by pressing the remote locking or unlocking button. If the key is working properly, the new battery should power the key’s electronic functions.
