Understanding Your Nissan Qashqai Key
Before diving into the steps, it’s essential to understand the type of key you have. Nissan Qashqais typically come equipped with either a traditional key fob or a smart key. A traditional key fob has a physical key blade and a separate button for locking and unlocking the car. A smart key, on the other hand, integrates the key blade and the electronic functions into a single unit. The process for changing the battery might differ slightly between these two types.
Identifying Your Key Type
- Traditional Key Fob: Look for a separate key blade that can be removed from the fob. The fob itself will have buttons for locking, unlocking, and potentially other features like trunk release.
- Smart Key: This key will be a single unit with the key blade integrated into the electronic housing. There might be a small button to release the key blade.
Gathering the Necessary Tools
Changing a car key battery is a straightforward task that requires only a few simple tools. Having these on hand will make the process smoother and more efficient:
- New Battery: Ensure you purchase the correct battery size for your Nissan Qashqai key fob. Refer to your owner’s manual or search online for the specific battery type.
- Small Screwdriver: A Phillips head or flathead screwdriver will likely be needed to open the key fob housing. The type of screwdriver required will depend on the specific design of your key fob.
- Tweezers (Optional): Tweezers can be helpful for safely handling the small battery and removing any debris from the key fob.
Changing the Battery in a Traditional Key Fob
For traditional key fobs, the process is relatively simple:
1. **Locate the Battery Compartment:** Examine the key fob for a small opening or a panel that can be removed. This compartment houses the battery.
2. **Open the Key Fob:** Use the appropriate screwdriver to carefully pry open the key fob housing. Be gentle to avoid damaging the plastic.
3. **Remove the Old Battery:** Once the key fob is open, you’ll see the battery. Gently remove it using your fingers or tweezers. Note the battery’s orientation for proper installation of the new one.
4. **Insert the New Battery:** Align the new battery with the positive (+) and negative (-) terminals in the compartment. Press it firmly into place.
5. **Close the Key Fob:** Securely snap the key fob housing back together.
Changing the Battery in a Smart Key

3. **Open the Battery Compartment:** Use the appropriate tool to carefully open the battery compartment.
4. **Remove the Old Battery:** Carefully remove the old battery, noting its orientation.
5. **Insert the New Battery:** Align the new battery with the terminals and press it firmly into place.
6. **Reassemble the Key:** Reinsert the key blade (if removed) and securely close the battery compartment.
Testing Your Key
After changing the battery, it’s essential to test your key to ensure it’s functioning correctly. Try locking and unlocking your car, and if equipped, test the trunk release and other features.
Troubleshooting Common Issues
If your key still isn’t working after changing the battery, here are some potential troubleshooting steps:
- Check the Battery Connections: Ensure the new battery is properly seated and making contact with the terminals.
- Inspect the Key Fob Housing: Look for any damage or debris that might be interfering with the key fob’s operation.
- Check the Key Fob’s Electronics: If you suspect an issue with the key fob’s internal electronics, you may need to have it professionally repaired or replaced.
