A small screwdriver (if necessary) A soft bristle brush (optional) A new CR32 battery Antistatic wristband (optional)Step-by-Step Guide
Here is a step-by-step guide to replacing the battery in your Nissan key fob:
Remove the Keychain: Detach the key fob from its keychain so that it is a standalone component. This will make it easier to manipulate the small components. Locate the Battery Cover: Inspect the back of the key fob for any indentations, textured areas, or slots. Some key fobs may also have a chrome ring that needs to be removed before opening the battery compartment. Open the Battery Compartment: If there is an indentation at one end, you can slide the cover open gently. If you see a slot, you can use a small screwdriver to pry it open. If the key fob has a chrome ring, remove it first to access the battery compartment. Battery Replacement: Once the compartment is open, remove the old battery. A CR32 battery is often used, and they can be sourced from most retailers that sell AAA, AA, or 3V batteries. Insert the new battery in the correct orientation, as the battery’s polarity needs to be correct for it to work. Close the Battery Compartment: When replacing the cover, make sure to align it correctly and snap it back into place. There should be a 'click' as it seats properly. Test the Key Fob: Activate the key fob’s lock button to be sure that your car responds appropriately. If it does not work, check the battery orientation; it may be reversed.Additional Tips
Here are a few additional tips to consider:
Removing Debris: If you notice any debris or dust in the battery compartment, use a soft bristle brush to gently remove it before replacing the battery. Antistatic Measures: Using an antistatic wristband can help prevent static electricity from damaging sensitive components in the key fob. Nissan Dealership: If you are unable to open the key fob, it may be best to take it to a Nissan dealership. They can perform the battery replacement for free and ensure the key fob is functioning correctly.Frequently Asked Questions
