How do I change the battery in a key fob on a Honda?

I have a 2019 Honda Passport EX. Recently, the key fob has been a bit unresponsive. I’m pretty sure it’s the battery. How can I change the remote battery on a Honda key?

Answer
In most cases, key fob batteries last about three years, so you’re right on the cusp of needing to replace the battery on your 2019 Honda Passport EX. The good news is that the process should only take you five minutes and cost about $2.
Follow these instructions to change the battery in a key fob on a Honda:
  • Look for a small tab on the back of the key fob (the side without the buttons), and push or pull it to release the key.
  • Slide the spare key out of the key fob.
  • Use the key to gently pry apart the key fob.
  • Once you have the key fob apart, you should see a battery on one side.
  • Use a pen to pry the battery out. It can be a bit stubborn and you don’t want to break the plastic tabs, so use caution.
  • Replace the battery with a CR2032 battery from your local pharmacy or home improvement store. A high-quality battery will cost about $2.
  • Repeat these steps in reverse order and your key fob should be like new.
