Nissan Cube Key Fob
Turn Over Key Fob
Remove Single Screw
This automotive "how-to" guide was specifically written to assist owners of the 3rd generation 2009, 2010, 2011, 2012, 2013 & 2014 Nissan Cube in replacing a worn out coin cell battery in the combination car key and keyless entry system remote control fob.

Owners of earlier 1998-2002 or 2002-2008 Nissan Cube vehicles or other Nissan models with similar key fobs such as the Versa, Sentra, Altima, Maxima, Juke, Rogue and Murano may also find this guide to be helpful.

New CR1620 3V coin cell, "button" or "watch" batteries are manufactured by Sony, Panasonic, Energerizer, Duracell and other companies.

They can be purchased at CVS, Wal-Mart, Walgreens or online from

To replace the battery in a Nissan Cube key fob, you'll need both a small Phillips head screwdriver and flathead screwdriver.

Phillips Head Screw Removed
Insert Screwdriver In Slot
Pry Open Fob Halves
The first step is to turn over the key fob and remove the single screw with a small Phillips head screwdriver.

Since the screw is easy to strip, I recommend using a # 0 Phillips screwdriver from a jewelers screwdriver set.

The screw is located on the back side of the key fob below the "Nissan" logo and near the metal blade of the car key.

Then insert a small flathead screwdriver into the notch on the side of the key fob near the lock button.

Gently pry apart the two halves of the key fob.

The old Sony CR1620 coin cell battery is attached to the rear half or "back cover" of the key fob with the negative "-" side facing up.

Use the small flathead screwdriver to pry out the old battery.

Test New Key Fob Battery
Insert the small Phillips head screw into the rear cover of the key fob and tighten it. If the screw was very loose or stripped, use some low strength purple Loctite thread locker.

Test the new battery by pushing the various buttons while standing next to your Nissan Cube.
