Honda Civic Key Fob Battery Replacement: Your Comprehensive Guide with Tools and Steps

Welcome to another quick episode of Kelvin’s Garage. Today, we have a very special episode in which we are going to change out the old battery from a 2016 Honda Civic key fob.

This is the key fob for my mom’s 2016 Honda Civic LX, and if you have the same key fob or something similar, this procedure probably works for you as well.

Over time, the frequent use of the key fob can lead to reduced range and finicky operations, indicating that it’s time to change the battery. Being the good son that I am, of course, I’m going to help my mom change out the battery.

Tools Needed

To get started, you will need a screwdriver, a plastic pick, and the replacement battery. The key fob uses a CR1620 battery, which can be found at most electronic stores for a reasonable price.

Replacing the Battery

To begin, remove the screw from the back of the key fob using a screwdriver. Next, using a plastic pick or the screwdriver, carefully separate the key fob body to access the old battery.

Gently pry out the old battery and replace it with the new CR1620 battery, ensuring it is properly seated. Finally, reattach the key fob body and screw it back together.


That’s it! Your 2016 Honda Civic key fob should now be good to go with its new battery. Remember that the battery should last for a few years, so you won’t have to worry about it for a while.
