Where to Locate the Key Battery
Finding the key battery’s location is crucial for a successful battery replacement. Here’s a detailed guide to help you pinpoint the battery’s exact position:
1. **Check the Key Fob’s Exterior**: Inspect the key fob for any visible screws or release buttons. Typically, there’s a small screw or a button concealed within a seam or crevice. Use a coin or screwdriver to gently pry open the key fob at this point.
2. **Examine the Circuit Board**: Once the key fob is open, you’ll see a small circuit board. The battery is usually attached to this circuit board, either soldered in place or held by a small metal clip. Carefully identify the battery’s position, avoiding touching any sensitive electronic components.
3. **Refer to the Owner’s Manual**: If you encounter difficulties locating the battery, consult your vehicle’s owner’s manual. It often provides detailed instructions and diagrams specifically for your Nissan key fob model.
| Battery Type | Battery Size | Location |
|---|---|---|
| CR2025 | Button Cell | Soldered to circuit board |
| CR2032 | Button Cell | Held by metal clip on circuit board |
| 3V Coin Cell | Round, silver-colored coin cell | Inserted into designated slot on circuit board |

Removing the Old Battery
Replacing the battery in a Nissan key fob is a relatively simple process that can be completed in a few minutes. To remove the old battery, follow these steps:
- Locate the battery compartment. The battery compartment is typically located on the back of the key fob. It is usually covered by a small plastic cover.
- Remove the battery cover. Gently pry the battery cover off with a small screwdriver or your fingernail.
- Identify the battery. The battery in a Nissan key fob is a small, coin-shaped battery. It is typically a CR2025 or CR2032 battery.
- Remove the old battery. Use a small screwdriver or your fingernail to gently pry the old battery out of the battery compartment. Be careful not to damage the battery or the battery compartment.
Here is a table summarizing the steps for removing the old battery from a Nissan key fob:
| Step | Instructions |
|---|---|
| 1 | Locate the battery compartment. |
| 2 | Remove the battery cover. |
| 3 | Identify the battery. |
| 4 | Remove the old battery. |
Inserting the New Battery
Once you have removed the old battery, it’s time to insert the new one. Here’s how:
Ensure that the positive (+) and negative (-) terminals of the new battery align with the corresponding terminals in the key fob. Misalignment can prevent the key fob from functioning properly.
Gently slide the new battery into the designated slot in the key fob. Avoid applying excessive pressure, as this could damage the battery or the key fob.
After inserting the battery, use the small screw or clip to secure it in place. Tighten the screw or clip until snug, but do not overtighten.
Once the battery is secured, test the key fob to ensure that it functions properly. Press the buttons to check if they activate the fob’s lights or signals.
If the key fob functions as expected, reassemble it by attaching the back cover or housing. Ensure it fits snugly and that there are no gaps or loose connections.
Closing the Key Fob
Once you have replaced the battery, it is time to close the key fob. To do this, simply align the two halves of the fob and press them together until they snap into place. Make sure that the buttons are facing the correct way and that the key fob is securely closed.
Troubleshooting
If you are having trouble closing the key fob, there are a few things you can check. First, make sure that the battery is properly inserted. The positive side of the battery should be facing up. If the battery is inserted incorrectly, it will not make contact with the terminals and the key fob will not work.
If the battery is inserted correctly and you are still having trouble closing the key fob, there may be a problem with the fob itself. You can try cleaning the terminals on the fob with a cotton swab and rubbing alcohol. If this does not work, you may need to replace the key fob.
| Issue | Solution |
|---|---|
| Key fob won’t close | Make sure the battery is inserted correctly. Clean the terminals on the fob with a cotton swab and rubbing alcohol. If this does not work, replace the key fob. |
Testing the Replaced Battery
Once you’ve replaced the battery in your Nissan key fob, it’s essential to test it to ensure that it’s functioning correctly. Here’s a detailed guide on how to test the replaced battery:
1. Insert the Key Fob into the Ignition Switch
Insert the key fob into the ignition switch of your Nissan vehicle. Twist the key to the “ON” position without starting the engine.
2. Press the Lock/Unlock Buttons
With the key fob inserted, press the lock and unlock buttons on the fob repeatedly. If the car’s door locks and unlocks accordingly, indicating that the key fob is sending and receiving signals.
3. Check the Indicator Light
Most Nissan key fobs have an indicator light that illuminates when the buttons are pressed. If the indicator light flashes or stays lit, it signifies that the battery is working correctly.
4. Test the Remote Start (If Applicable)
If your Nissan key fob has remote start capabilities, press the remote start button on the fob while standing away from the vehicle. If the car starts successfully, the battery is functioning adequately.
5. Check the Distance Range
Move away from your Nissan vehicle gradually and press the lock or unlock button on the key fob. Note the maximum distance at which the fob can successfully operate. A reduced range could indicate a weak battery or other signal interference issues.
6. Use a Multimeter (Optional)
If you have a multimeter, you can measure the voltage of the replaced battery to verify its strength. Connect the multimeter to the battery terminals and check if the voltage reading is within the manufacturer’s specifications.
7. Time the Battery Life
To assess the battery’s longevity, keep track of how long it lasts before needing to be replaced again. If the battery’s life is significantly shorter than before, it could indicate a problem with the fob’s circuitry or other factors affecting power consumption.
Troubleshooting Common Issues
Battery Indicator Light Not On
If the battery indicator light on the dashboard doesn’t come on when you start your vehicle, it could be a sign that the battery is completely dead and needs to be replaced. You can try replacing the battery with a new one to see if that solves the issue.
Vehicle Won’t Start
If you’ve successfully replaced the battery and your vehicle still won’t start, it could be due to a number of other issues, such as a faulty starter, alternator, or fuel pump. It’s best to have your vehicle inspected by a qualified mechanic to determine the exact cause of the problem.
Key Fob Not Working
If your key fob is not working, it could be due to a number of reasons:
