If you’re experiencing issues with your 2015 Nissan Altima key fob, like decreased range or unresponsive buttons, it might be time to replace the battery. Thankfully, this is a quick and easy process that can be done at home without any special tools. This guide will walk you through each step to get your key fob working like new again.
One of the first signs you may notice when your key fob battery is low is decreased responsiveness. You might find yourself having to press the buttons multiple times or stand closer to your car for the signal to register.
What You Need to Change the Battery
Before you begin, gather the following items:
- A new CR2025 battery (widely available at most stores)
- A small flat-head screwdriver or a plastic pry tool
Step-by-Step Guide to Replace Your Nissan Altima Key Fob Battery
Here’s how to replace the battery in your 2015 Nissan Altima key fob:
- Locate the release button: On the back of your key fob, find the small, recessed button. This button releases the mechanical key.
- Release the mechanical key: Press and hold the release button while gently sliding the mechanical key out of the fob.
- Open the key fob: Using your flat-head screwdriver or pry tool, carefully insert it into the groove where the mechanical key was located. Gently pry open the two halves of the key fob. You should hear a click when it separates.
- Remove the old battery: Inside the fob, you’ll see the battery held in place by a small clip. Carefully lift the old battery out, noting the positive (+) and negative (-) sides.
- Insert the new battery: Place the new CR2025 battery into the compartment, making sure the positive (+) side faces up, just like the old battery.
- Reassemble the key fob: Align the two halves of the fob and press them together firmly until you hear a click.
- Reinsert the mechanical key: Slide the mechanical key back into its slot until it locks into place.
Testing Your Key Fob
Once the key fob is reassembled, test all the buttons to make sure they function correctly. If the buttons still don’t work, try repeating the process, ensuring the new battery is properly seated and making good contact.
Replacing a car key fob battery can seem daunting, but it’s actually a simple process that anyone can do.
