| This
automotive "how-to" guide was specifically written to assist owners
of the 2nd generation (2009, 2010, 2011, 2012, 2013 & 2014) Honda Fit (or "Jazz" outside the USA) in replacing the coin
or "button" cell battery inside the combo car
key and keyless entry system remote control. Owners of other Honda or Acura vehicles such as the Accord, Crosstour, CR-V, CR-Z, Element, Civic, Insight, Odyssey, Pilot, Ridgeline, RL, TL. TSX, ZDX, MDX, and RDX may also find these instructions to be helpful. The original battery in a Honda Fit key fob remote control is a Panasonic CR1616 3V coin cell type battery. Replacements can be purchased at Amazon.com or retailers such as CVS, Walgreens, or Wal-Mart. I usually purchase coin batteries on Amazon where a 5 pack can be bought for just a few bucks with free shipping. The only tools needed to open the remote control and replace the battery is a small # 0 Phillips head screwdriver from a jewelers screwdriver kit. A small flathead screwdriver can also be helpful for prying open the pieces. |

 Tiny Phillips Head Screw |
 Pry Open Rear Cover |
 Rear Cover Removed |
| The first step is
to locate and remove the tiny Phillips head screw on the rear cover of the
remote control located near the metal ignition key blade. Then use a small flathead screwdriver to pry off the rear cover of the key fob. Below the rear cover you'll find the rectangular remote control unit. Remove it by tapping it out or pushing it out of the case using the remote's buttons on the other side. |

battery with a new CR1616 3 Volt cell by pushing it in with the "+" side
facing down into the rear cover of the remote control unit.
Then orientate the two halves as shown above and snap them back together. Test the new battery by pushing on the buttons to see if the red LED light illuminates brightly. |

Phillips head screwdriver to tighten the single screw located on the rear of
the key fob close to the metal blade of the car's ignition key.

battery again by pressing the buttons and verifying that the various
functions work properly while standing near your Honda Fit or Jazz. |
