Identifying Your Nissan Car Key Battery Type
Before you begin, it’s crucial to determine the specific type of battery your Nissan car key uses. Different key models may require different battery sizes and specifications. The battery information is usually found on a small sticker located inside the key fob or on the battery itself.
Common Nissan Car Key Battery Types
- CR2032: This is a widely used coin-shaped battery found in many Nissan car keys.
- CR2025: Similar to the CR2032 but slightly smaller in diameter.
- CR1616: Another common coin-shaped battery used in some Nissan models.
If you can’t locate the battery information, consult your Nissan owner’s manual or contact a Nissan dealership for assistance. Having the correct battery type on hand will ensure a seamless replacement process.
Gathering the Necessary Tools
To change your Nissan car key battery, you’ll need a few basic tools:
- A small flathead screwdriver or a key fob opening tool
- The correct replacement battery (refer to the previous section for battery types)
- A small piece of cloth or paper towel
Optional tools that may be helpful include:

Step 1: Open the Key Fob
Locate the small seam or tab on the back of your Nissan car key fob. This seam or tab usually conceals the battery compartment. Using a small flathead screwdriver or a key fob opening tool, gently pry open the seam or tab. Be careful not to apply excessive force, as you could damage the key fob.
Step 2: Remove the Old Battery
Once the key fob is open, you’ll see the old battery. Carefully remove the battery from its compartment. Note the battery’s orientation, as the new battery must be inserted in the same way.
Step 3: Insert the New Battery
Take the new battery and align its positive (+) and negative (-) terminals with the corresponding markings in the battery compartment. Gently press the new battery into place until it sits securely.
Step 4: Close the Key Fob
Carefully align the two halves of the key fob and gently press them together until they snap shut. Ensure that the seam or tab is securely closed.
Step 5: Test the Key Fob
To test your newly replaced battery, try using the key fob’s buttons, such as locking, unlocking, or remote start. If the buttons respond as expected, the battery replacement was successful.
Troubleshooting Common Issues
If you encounter any problems during the battery replacement process, here are some common troubleshooting tips:
Key Fob Not Opening
If the key fob seam or tab is difficult to open, try using a slightly wider tool or applying gentle pressure in a different direction. Avoid using excessive force, as this could damage the key fob. (See Also: How Much Does a New Car Battery Cost? On Average)
