Tools Required
You won’t need a lot of tools for this simple task. Just one small item will do:
- Small Flathead Screwdriver – A mini flathead screwdriver, like those used for eyeglasses repair, is ideal for carefully opening the key fob casing.
Preparation Tips
Before you start, a little preparation can make the process smoother and prevent any damage:
- Protect the Fob: Use a thin microfiber cloth to cover the tip of your screwdriver. This will prevent scratches on the key fob’s plastic casing and internal electronic components.
- Remove from Key Ring: Take your key fob off your keyring to give you more room to work and avoid accidentally damaging your keys.
Understanding the Emergency Key
Every Nissan Altima key fob includes a hidden emergency ignition key. This metal key is a lifesaver if your key fob battery dies when you’re away from home. You can access this key to manually unlock your car door using the keyhole located on the underside of your door handle.
Before you can replace the battery for your 2015 Nissan Altima key fob, you’ll need to remove this emergency key. The steps below will show you how.
Step-by-Step Guide: 2015 Nissan Altima Key Fob Battery Replacement
Follow these detailed steps to successfully complete your 2015 Nissan Altima key fob battery replacement:
-
Position the Key Fob: Place the key fob on a flat surface with the buttons facing downwards.
-
Remove the Emergency Key: Locate the small release tab on the key fob.
Push the tab towards the edge of the key fob and simultaneously pull the bottom edge of the key fob downwards. The metal emergency key should slide out easily. Set the key aside in a safe place.
- Open the Key Fob Casing: Turn the key fob over so the buttons are facing upwards. Look into the slot where you just removed the emergency key. You’ll see two small notches on the bottom plastic edge.
Carefully insert your mini flathead screwdriver into one of these notches. Gently twist the screwdriver to pry apart the two halves of the key fob. If one notch is too tight, try the other. Once you have a gap, carefully separate the top half of the fob from the bottom half.
- Replace the Old Battery: With the top half of the casing removed, you’ll see the CR2032 battery for your 2015 Altima key fob.
Use your screwdriver to gently pry out the old battery. Be careful not to scratch any of the surrounding electronic components. Take the new CR2032 battery and push it into place, ensuring the positive (+) side is facing upwards.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing. Gently press them together until they snap securely shut. Make sure all edges are flush.
-
Reinsert the Emergency Key: Slide the metal emergency key back into its slot until you hear a click, confirming it’s securely locked in place.
