Battery replacement - how to change Nissan key fob battery

Changing a Nissan key fob battery is a simple process that can be done in just a few minutes. The exact steps will vary depending on the model of your Nissan, but the general process is as follows:

  1. Gather your tools. You'll need a small flat-head screwdriver and a new CR2032 battery.
  2. Remove the emergency key. There is usually a small button or lever on the side of the fob that will release the emergency key.
  3. Open the fob. There is usually a seam or gap on the fob that you can pry open with the screwdriver. Be careful not to damage the fob.
  4. Remove the old battery. The battery will be located inside the fob, usually held in place by a clip or spring. Gently pry the battery out with your fingernail or the screwdriver.
  5. Insert the new battery. Make sure that the positive (+) side of the battery is facing up.
  6. Close the fob. Snap the fob back together until it is closed.
  7. Test the fob. Try to unlock your car with the fob. If it works, you're done!

Some quick tips:

If you're having trouble opening the fob, you can try using a thin piece of plastic, such as a credit card, instead of a screwdriver (saves you marking the fob also!)

Be careful not to touch the metal contacts on the battery or the circuit board inside the fob as this could damage the fob and could lead to a costly replacement!

But if you're not comfortable changing the battery yourself, visit your local Chorley Group Nissan dealership and we'll be able to change it for you for a small fee.
