How to Open Your Honda Key Fob & Replace the Battery

Man opening car with key fob

 

With the key fob that comes with your new Honda car, truck, or SUV you can conveniently lock and unlock your car doors, remotely start the engine, activate memory seat settings, and more. But at some point down the line, you’ll find that you’ll need to replace the Honda key fob battery. While you can always count on the service team at Patty Peck Honda to change the battery for you, it is really very easy for you to change it yourself. In this Honda key fob battery replacement guide, we’ll walk you through the steps so you can get back to enjoying all the features and functions you’ve come to rely on when you’re out-and-about in the Madison area.

Choosing the Right Honda Key Fob Battery

Your Honda key fob uses a flat, circular 3-volt battery which can be found at just about any Jackson-area hardware store. At the Patty Peck Honda Parts Center we always have Honda key fob batteries in stock, as well, and you can order a Honda key battery from us online, and we’ll have it ready for you to pick up at our dealership in Ridgeland at your convenience.

Honda Key Battery Replacement

Ready to find out how to change a Honda key fob battery? The following steps will show how to open a Honda key fob, how to remove/replace the battery, and how to put the key fob back together.

  1. Press and slide the button that releases the metal key, and then slide the key out.
  2. Use the key or a small flathead screwdriver to gently pry the key fob open.
  3. Press your thumb down right above the battery to hold the fob together so the contents and external buttons don’t fall out.
  4. Remove the dead battery, taking note of the positive and negative sides in order to install the new battery correctly. Don’t touch the terminals on the new battery. The oils on your skin can cause corrosion, which shortens battery life.
  5. Insert the new battery in the same position as the old one. Use the positive (+) and negative (-) marks inside the key fob as a guide.
  6. Align the two halves of the key fob and gently apply pressure until they snap back together.

If your Honda key fob has a screw that holds the two halves together instead of a button, use a small flathead screwdriver to remove the screw, and then follow the steps above to replace the battery.

How to Program a Honda Key

Now that you know how to change a Honda key battery, the next thing to find out is how to program it. The following steps demonstrate how to program a Honda key.

  1. Enter the vehicle, make sure all the doors are shut, and have your key and the fobs to be programmed ready.
  2. Insert the key and turn to the “On” position. Then, press and hold the “LOCK” on the key fob button for one second.
  3. Release the button and turn the key to the “Off” position. Repeat this process twice more.
  4. Turn the key to the “On” position, hold the “LOCK” button on the key fob for one second, and wait for the doors to lock and unlock automatically. Once the locks have cycled, your vehicle will be in remote programming mode.
  5. Once again hold the “LOCK” button on the key fob for one second. The locks will cycle, and the key fob will be paired with your vehicle. Repeat the process with any additional fobs that need programming.
  6. Exit the programming mode by turning the key to the “Off” position in the ignition.
