This automotive maintenance tutorial was specifically written to assist owners of the second generation (2009, 2010, 2011, 2012, 2013 & 2014) Nissan Murano SUV in changing a dead coin cell battery in the smart or "intelligent" key fob remote control for the keyless entry system.

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.

Carefully Pry Out Old Battery
Insert the blade of your small flathead screwdriver in to one of the two notches on the edge of the fob where the metal ignition key used to reside.

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.

Replace Metal Ignition Key
Test New Key Fob Battery
Slide the back up metal ignition key in to place.

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.)
