Replacement Parts

The only part you’ll need to get your key fob working again is the replacement battery itself:

  • 3-volt coin cell battery — Part #CR2032

You might already know it as the thumbnail-sized cell you use to replace a dead watch battery. They’re easy to find at any Reading hardware store, from various manufacturers including Panasonic, Sony, Energizer, Maxell, and Duracell.

However, we recommend checking your user manual to find out which battery is the original equipment used by the manufacturer. For example, the OEM battery on your 2014 Nissan Altima might be a Panasonic CR2032 3V coin cell. If that information isn’t in your manual or you have any questions, bring your key fob to Rolls Auto Sales in Philadelphia, where we’ll be happy to help you out.


  • Mini flathead screwdriver – A small flathead screwdriver, about the size you’d use for a pair of glasses, works best to pry open the two plastic halves of the key fob.


  • To avoid scratching the electronic components inside the fob, or the plastic panels on the outside, get a thin microfiber cloth for covering the screwdriver head.
  • Remove the key fob from your key ring.

What is the Emergency Ignition Key?

Every keyless entry system comes with an emergency metal key stored inside the key fob. This ensures that you’ll never be stranded far from Allentown if your key fob battery dies unexpectedly! Your car’s door handle should have a small keyhole on the underside to insert the key and unlock the car manually.

Before you can perform 2015 Nissan Altima key fob battery replacement, you’ll first need to remove the emergency key from the fob. Read the steps below for details!

How to Replace the Battery in Your Nissan Key Fob

For correct 2015 Nissan Altima key fob battery replacement, follow these steps closely:

  • Set the key fob on a table with the buttons facing down.
  • Remove the metal ignition key — You should see a small slider tab. Push the tab toward the outer edge of the key fob to release the metal ignition key. Pull the bottom edge of the key fob downward, and the key should slide out. Make sure to set the emergency key aside someplace you won’t lose it!
  • Pry apart the fob — With the key fob buttons facing up, look into the slot where the emergency key used to be. You should see two notches on the plastic bottom edge of the fob. Carefully insert your flathead screwdriver into one of the notches, and use it to pry apart the two halves of the fob. If it’s stubborn, try the other notch. Remove the top half of the fob.
  • Replace the battery — With the top half removed, you should see the battery. Carefully pry it out with your screwdriver, taking care not to scratch the components. Push in the new battery with the positive side facing up.
  • Reassemble the fob —Line up the front half and the rear cover of the key fob and gently push them together, making sure they’re flush at every edge. Push the metal ignition key back into the slot until it clicks securely in place.
