Replacing the battery in your Nissan key fob is a relatively simple task that can be completed in just a few minutes. All you need is a new battery and a small screwdriver. In this article, we will provide you with step-by-step instructions on how to change the battery in a Nissan key fob.
The first step is to locate the small screw on the back of the key fob. Once you have found the screw, use the screwdriver to carefully remove it. The key fob will then split into two halves. The battery is located in the bottom half of the key fob.
To remove the battery, simply use your finger or a small tool to gently pry it out. Be careful not to damage the battery or the key fob. Once you have removed the old battery, insert the new battery into the key fob. Make sure that the positive terminal of the battery is facing up.
Gathering Necessary Tools
Replacing the battery in your Nissan key fob is a simple and straightforward process that requires only a few basic tools. Before you begin, make sure you have the following items on hand:
Phillips-Head Screwdriver
Most Nissan key fobs use a small Phillips-head screw to hold the back cover in place. You will need a screwdriver that is small enough to fit the screw, but not so small that it will strip the head.
New Battery
The type of battery required for your Nissan key fob will vary depending on the model. Consult the owner’s manual for the specific battery type. It is important to use the correct battery, as using the wrong type can damage the key fob.
Small Flat-Head Screwdriver (Optional)
In some cases, you may need to use a small flat-head screwdriver to pry open the back cover of the key fob. This is not always necessary, but it can be helpful if the cover is stuck.
| Tool | Description |
|---|---|
| Phillips-head screwdriver | Small enough to fit the screw holding the back cover in place |
| New battery | Correct type for your Nissan key fob |
| Small flat-head screwdriver (optional) | May be needed to pry open the back cover |
Removing the Key and Opening the Fob
1. Locate the key release button. It is usually a small, round button on the side of the fob. Press and hold the button while pulling the key out of the fob.
2. Separate the fob into two halves. Gently pry open the two halves of the fob using a small flathead screwdriver or a butter knife. Be careful not to damage the fob.
3. Locate the battery. The battery is usually a small, round coin cell battery. It will be held in place by a metal clip or a piece of tape.
Replacing the Battery
1. Remove the old battery. Use your fingers or a pair of tweezers to remove the old battery from its compartment.
2. Insert the new battery. Place the new battery into the compartment, making sure that the positive (+) and negative (-) terminals are correctly aligned.
| Battery Type | Size | Voltage |
|---|---|---|
| CR2025 | 20mm x 2.5mm | 3V |
| CR2032 | 20mm x 3.2mm | 3V |
3. Secure the battery. Use the metal clip or tape to secure the battery in place.
Locating and Removing the Old Battery
Opening the Key Fob:
Locate the small release button or lever on the side of the key fob. Press or slide it to open the fob into two halves.
Identifying the Battery:
Once the fob is open, look for a small, round or button-shaped battery. It will typically be located in a designated compartment or held in place by a spring clip.
Removing the Battery:
Use a small screwdriver or thin tool to gently pry the battery out of its compartment. **Be careful not to touch the metal contacts on the battery or the inside of the fob, as it may damage the electrical components.** If the battery is held in place by a spring clip, simply press down on the clip and remove the battery.
Note: Different Nissan key fob models may have slightly varied battery compartments. Refer to the owner’s manual for specific instructions if needed.
Battery Specifications:
Nissan key fobs typically use a CR2025 or CR2032 button cell battery. The exact type may vary depending on the fob model. It’s recommended to replace the battery with the same type to ensure proper functionality.

| If the fob doesn’t close properly, it may not function correctly. Check for any obstructions or misalignment and try again. |
7. Press the lock or unlock button to test if the fob is working correctly.
Inserting the Key
1. Find the keyhole on the Nissan vehicle and insert the metal key.
2. Push the key in until it clicks and is fully inserted.
3. Turn the key to the desired position (e.g., ignition, door lock/unlock).
4. Remove the key and store it in a safe and accessible location.
Testing the Fob’s Functionality
Before you start replacing the battery, it’s important to test the fob’s functionality to ensure that the battery is actually the issue. Here’s how to test your Nissan key fob:
- Check if it locks and unlocks the doors: Press the lock and unlock buttons on the fob and observe if the car’s doors respond accordingly. If they don’t, proceed to the next step.
- Test the panic button: Press the panic button on the fob and listen for the car’s alarm to sound. If the alarm doesn’t sound, your fob may need a new battery.
- Examine the indicator light: Some fob models have an indicator light that flashes when the battery is low. Check if the light is flashing or blinking abnormally.
If your fob fails any of these tests, it’s highly likely that the battery needs to be replaced. However, if the fob passes all the tests, the issue may lie elsewhere, such as a problem with the car’s receiver or the fob’s circuit board.
Safety Precautions
Before you begin, it’s important to take these safety precautions:
- Park your Nissan on a flat surface and set the parking brake.
- Turn off the engine and remove the key from the ignition.
- Locate the key fob and make sure it is within reach.
- Gather the tools you’ll need: a small screwdriver or a pair of needle-nose pliers.
- If you have a newer Nissan model, you may need a CR2032 battery. For older models, you may need a CR2025 battery.
- Make sure the battery you purchase is compatible with your Nissan key fob model.
- Do not use a damaged or leaking battery.
- Dispose of the old battery properly.
- Be careful not to touch the battery terminals with your bare hands.
Battery Replacement Frequency
The frequency with which you need to replace the battery in your Nissan key fob will vary depending on how often you use your vehicle and the type of key fob you have. However, as a general rule of thumb, you should expect to replace the battery every 1 to 3 years. If you use your vehicle frequently, you may need to replace the battery more often. Additionally, some key fobs require more power than others, and thus may have a shorter battery life.
Here are some signs that your Nissan key fob battery may need to be replaced:
- The key fob is not working properly.
- The key fob’s buttons are not responding.
- The key fob’s range is decreased.
- The key fob’s LED light is not blinking.
If you are experiencing any of these problems, you should try replacing the battery in your key fob. To do this, you will need to:
1. Locate the battery compartment on the back of the key fob.
2. Use a small screwdriver or coin to open the battery compartment.
3. Remove the old battery and replace it with a new one of the same type.
4. Close the battery compartment and test the key fob to make sure it is working properly.
