This automotive maintenance tutorial was specifically written to assist owners of the fourth generation (2013, 2014, 2015, 2016 and perhaps also the revised 2017 model year) Nissan Pathfinder SUV in changing a dead battery in the intelligent key fob remote control for the keyless entry and push button start systems.

Owners of other Nissan or Infiniti vehicles such as the Versa, Maxima, Juke, Rogue, Altima, Xterra, Sentra, Murano, Cube, Armada, Leaf, Quest, Frontier, Teana, 370Z, GT-R, Titan, G25, G37, M35, QX56, QX60 and M37 may also find these DIY instructions to be helpful.

A replacement coin cell (A.K.A. "button" or "watch") battery is part number CR2032 which is available at Walmart, CVS, Walgreens or online at

The only tool needed to access and replace the key fob battery is a flathead screwdriver or a plastic pry bar tool.

Release Ignition Key
Backup Key Removed
Insert Flathead Screwdriver
The first two steps are to separate the fob from the key ring with your other keys and then turn it over.

Locate the small black plastic switch or button on the back side of the fob.

Slide the switch to release the backup metal ignition key and slide it out of the fob.

Set the metal ignition key aside in a safe place.

Insert the blade of the small flathead screwdriver or a plastic pry bar tool in to the notch where the metal key used to reside.

Gently pry apart the two halves of the fob.

Pry Out Old Battery
You might need to remove the screwdriver and re-insert it in to another section of the fob to separate the two halves.

Try to avoid using excessive force. The two halves of the fob should pop apart relatively easily.

Use either your finger nail or the small flathead screwdriver to carefully pry out the old battery from its socket.

Line Up Two Halves
Push a new # CR2032 coin cell battery in to the socket with the "+" positive side facing down and the "-" negative side facing up towards you.

Line up the two halves of the fob.

Snap Together Key Fob
Slide In Metal Ignition Key
Test New Key Fob Battery
Gently push together the two halves of the key fob.

Make sure that the two halves of the fob are flush together at every edge.

Slide the backup / emergency metal ignition key back in to its slot.

To test the new battery, stand near your SUV and press the "Unlock" or "Lock" button on the key fob.

If the new battery is working properly, you should see the parking lights flashing and also hear the door locks opening or closing.
