Owners of other Nissan or Infiniti vehicles such as the Versa, Maxima, Juke, Rogue, Altima, Xterra, Pathfinder, Sentra, 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 from various manufacturers such as Sylvania, GE, Duracell, Energizer, Maxell, Panasonic and Sony.

The only tool needed to replace the battery is a small flathead screwdriver used to pry apart the two halves of the fob.

Slide the tab over to the other side and pull out the back up metal ignition key.

Set the ignition key aside in a safe place.

Gently pry apart the two halves of the key fob.

You may also be able to use a coin, butter knife, nail file, a house key or any other similarly shaped item to pry apart the fob.

Either pull out the old battery from the socket in the rear cover with your fingernail or carefully pry it out with the flathead screwdriver.

Make sure that the front and rear of the fob are flush together at every edge.

To test the new key fob battery, stand near your Murano and press the "Unlock" or "Lock" buttons.

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

(Tip - To turn off the horn "honk" confirmation when locking your Murano, which might annoy your neighbors at night, press and hold both the "Lock" and "Unlock" buttons at the same time for a few seconds until you see the parking lights flash.)
