How to Know When You Need a New Honda Key Battery

Honda has done a great job on its newer models of letting Gaffney, SC customers know when the Honda key battery needs replacing. When you start your car, the dashboard will show a message that your Honda key battery is low. If you miss this message, there will be a persistent yellow icon on the screen, letting you know that your vehicle needs attention. On older models, if you must hit the button multiple times before your car unlocks, your key fob battery might be failing, and it is time to do a Honda key fob battery replacement.

Honda Key Fob Battery Replacement: How to Open a Honda Key Fob

To start your Honda key fob battery replacement, you need to know which battery to buy. You can either look up your Honda model online, contact the service center at Renaldo Honda to be 100% certain you are getting the right battery, or dismantle the fob to see what type of battery it has.

Newer models with the fob attached to the key have a release button on the fob’s backside. When the key is removed, you can set the key between the front and back and turn it to pop the fob open. Older Honda models may have a screw if it is attached to the back of a key.

Steps to Change the Battery In Honda Key Fob

  1. While the fob is open, hold it together by pressing your thumb where the battery is, so the pieces stay in their proper location.
  2. Use your free hand to remove the battery, and if you already purchased your battery, use this opportunity to pop the new one back in. The flat side should face down.
  3. If you are checking for the proper battery to buy, there is visible writing on the battery saying what type of battery you need to purchase.
  4. Most Honda key fobs use a 3volt battery. One of the more popular models is CR2025, but not all key fobs use this specific battery, so please check.
  5. Once your new battery installation is complete, line the key fob’s front and back together and press it back into place. Replace screws if necessary.
  6. If you are using the new smart key fobs, reinsert your Honda key and flip the switch back to the locked position.
