How to Replace the Battery in a Honda Fit Remote Key?
3 Answers
Method to replace the battery in a Honda Fit remote key: First, press the button on the electronic key to eject the mechanical key. There is a notch where the mechanical key is covered. Insert a coin into the notch and twist it clockwise to separate the electronic key into two parts: the electronic board and the power supply. At this point, you can see the battery. Remove the old battery by hand and replace it with a new one. The Honda Fit has dimensions of 4065mm in length, 1695mm in width, and 1525mm in height, with a wheelbase of 2530mm, and features front-engine, front-wheel drive. In terms of power, the Honda Fit is equipped with a 1.5-liter naturally aspirated Earth Dreams engine, delivering a maximum horsepower of 131 hp and a maximum torque of 155 Nm. The engine reaches its maximum power at 6600 rpm and its maximum torque at 4600 rpm.
As a long-time Fit owner, I've replaced the key fob battery more than once. It's a simple task but requires care. First, find a plastic pry tool, like a credit card or a specialized tool, and gently insert it into the side gap of the key to pry open the casing—avoid using excessive force to prevent damaging the plastic. Inside, you'll find a coin cell battery, usually a CR2032. Note the orientation of the old battery (typically label-side up), remove it, and replace it with a new one, ensuring the same alignment. Reassemble the cover, press it firmly, and test the unlock button to confirm it works. It's recommended to replace the battery every two years to prevent failure—these batteries cost just a few dollars at supermarkets. After replacement, the remote range will be restored, ensuring safe entry and exit. If you notice dust inside during disassembly, clean it out to maintain sensitivity.
I've repaired many Fit key fobs, and replacing the battery requires careful operation: Use a plastic pry tool to gently open the case along the edges—avoid metal tools to prevent scratches. The internal battery is a CR2032; remove it carefully and note the installation orientation before placing the new battery correctly. Close the cover and press firmly, then test the unlocking sensitivity. The battery replacement itself takes just minutes, but if the key has water damage or other issues, inspect it first. Regular maintenance, like testing button response every six months, extends the key's lifespan. Using OEM batteries ensures more stable performance—don't cheap out on low-quality ones to avoid circuit damage.
