Everything you need to know about Honda Civic Key Fob Battery Replacement

Find the right exact key fob battery and the guide for each Honda civic key fob battery replacement.

The Honda Civic is, indeed, a commendable subcompact car. The Civic has enjoyable steering, a plush cabin, and great gas mileage. This Honda’s standard engine won’t blow your mind, but the turbocharged upgrade will give you serious street cred. The Civic’s cabin features cutting-edge gadgetry, all of which is presented in a sleek and contemporary package. There is plenty of space for passengers in both rows, and the trunk is very large for its class. Among compact cars, the Civic offers the best balance of quality and affordability.

Among its competitors, the Civic stands out as a great choice because of the flexibility it provides. You have the option of choosing a hatchback or a standard sedan. A vast variety of infotainment and driver assistance features are included in the price of even the most basic trim level.

Civics Around the World

Civics have been marketed and sold in many countries, although Japan, China, the US, Canada, and parts of Europe have consistently recorded the most sales. From that first car in 1972 to today, there have been more than 19 million Civics sold around the world and more than 7 million in the US alone. Although the Civic doesn’t vary much from country to country, the name of the car is very often different.

Can I drive my car with my key fob battery dead?

Yes. You can use your Honda Civic even if the key fob battery is dead. Key fob Batteries die without affecting car performance. Since the beginning of the key fob, automobile manufacturers have been prepared for this issue. If the battery on your key fob were to die while you were driving, nothing would happen. Because the key fob is solely a mechanism for unlocking and starting the vehicle, the car will continue to function normally even without it.

There is no chance that the key fob will have any effect on the ignition or the engine once the vehicle has been set in motion. However, you need to keep your car battery working well because you will need the keys to access it and drive it. Functionalities relating to remote locking and securing will not work when the battery is dead.

Symptoms of Honda Civic Key Fob Low Battery

The Honda Civic has used 3 different key fob models over its 3-decade span. Key fob battery problems on Honda Civics can be really frustrating. Many people who own cars are oblivious to the clear warning indications that their battery is fading. They either “hope for the best” or don’t pay enough attention to the way the remote works.

The low battery warning light on a Honda civic fob key illuminates if the voltage of the key’s battery falls below a certain threshold. This serves as a warning when replacement batteries are required. When this indicator light turns on, the problem with your Honda Civic car key can be fixed with any easy replacement battery.

You do not want a dead battery because it will render the actual remote control unit inactive. In this tutorial on how to change the battery in a Honda Civic, I will also demonstrate how to swap out the battery in each of the remote key fobs that have been utilized by the Civic over the years.

The following are the major symptoms that your Honda fob battery needs a replacement:

  1. Weak signal strength: The vast majority of Honda key fobs can open a vehicle from a distance of approximately 50 feet. Many car owners use this feature so that they can check to see if they closed the vehicle before leaving the parking lot. As the power from the battery continues to run down, you will need to get closer to the car in order to open or close the door.

  2. Warning light for the low battery: Some Honda models may indicate to the driver that the key fob battery is about to run out by illuminating a warning sign on the dashboard in the form of a flashing light.

  3. Multiple clicks: Your Honda car door should open with a single click from the key. If you need to click more than twice, this indicates that the battery is getting low. From that point on, you are considered to be in the “risk zone” because the car door might not open the next time.

A key fob that doesn’t work properly is not just annoying but also potentially hazardous. If you are unable to lock the vehicle consistently, both your vehicle and your belongings may also be at an increased risk of theft. Read on for the easiest guide on Honda Civic key fob battery replacement.

Step 1:

Flip the key over to the back and remove the small screw at the back with a precision screwdriver set as shown above. Press down hard on the screw with the screwdriver to get the screw out

Step 2:

Put a small flathead screwdriver or any thin flat metal into the small notch at the base at the left side of the key (the key should still be flipped over to the back) and give it a twist until the base(the front of the key that is now turned to the back ) of the key starts to come apart

Step 3:

There is a connection point at the top that may make the pulling off difficult. Pull on the little space you have created at the base of the key while holding down and pulling the metal part of the key towards you to make the upper part( the base you previously flipped) to come off.

Step 4:

You now have access to the internal part and piece of the key that you need to work on. Pull out the plastic case with buttons. Set aside the upper and lower base that you have pulled apart.

Step 5:

The internal middle piece with the buttons has a notch at the upper part which allows you to get access to the battery. Put a flat screwdriver into the notch and twist. The battery holder will pop open to reveal the key battery. Give the battery a little pop underneath with a flat screwdriver and the battery will fall out.

Step 6:

Check the battery type to be sure you have the right key fob replacement battery. Put in the new battery to replace the old one; make sure the positive side is down and away from you and it’d pop back in. You can press it a little to ensure it’s firm.

Step 7:

Pick up the internal middle piece and assemble it by pressing the two sides against each other. They’d snap back together with little or no effort. Now place the middle piece into the front cover and carefully place the rear cover over the middle piece in the front cover. Make sure they snap perfectly together by pressing the base together.

Put the screw back in and screw.
