April 1st, 2024 by

If you’ve had a Nissan for long enough, you might have encountered a situation where your key fob starts acting up. If this happens consistently, then it is a sign that the battery within the fob is dying or dead. Thankfully, the steps for replacing a dead key fob is an easy process so you don’t have to grab that emergency key.

Opening Your Nissan Key Fob

The first step to replacing your Nissan key fob battery is to open it. This might seem daunting, but it’s quite straightforward:

  • Locate the Hidden Key: Every Nissan key fob contains a hidden key inside it. You can access this by pushing the release latch or button on the fob. A flat-head screwdriver can be used to open this latch if you are concerned about using your nails.
  • Use the Hidden Key: Once you have the key out, use it to gently pry open the key fob case. Insert the key into the small slot or opening usually located on the side of the fob.

Replacing the Battery

Now that you’ve got your key fob open, it’s time to change the battery:

  • Identify the Type of Battery: Look for the battery type, which is typically a CR2025 or CR2032 3V battery. You can find this information written on the old battery.
  • Remove and Replace the Battery: Carefully remove the obsolete battery without touching the new one’s contacts. Place the new battery in the same position as the old one, ensuring the positive (+) side is facing upwards.

It’s crucial not to touch the new battery’s contacts with your fingers, as oils and dirt can affect performance. Once the new battery is in place, simply snap the key fob case back together, and test the locking and unlocking buttons to ensure the new battery is working properly.
