How to Change Battery of Honda Car Key

Step 1: Purchase Appropriate Battery

Before changing the battery of your Honda car key, you will need to purchase the right type of battery. Look in your car key’s manual or do some research online to find out the specific type of battery your key requires.

Step 2: Open the Car Key

Next, you will need to open your Honda car key to access the battery. Look for a small button on the key that allows you to release the metal key itself. Once you release it, you should be able to pry open the rest of the key using a flathead screwdriver or similar tool.

Step 3: Remove and Replace the Old Battery

With the key open, you should now be able to see the old battery. Carefully remove it and dispose of it properly. Insert the new battery in its place, making sure that the positive (+) side is facing up.

Step 4: Reassemble the Key

Once you have replaced the battery, you can now begin closing up the key. Make sure to put all the pieces back together securely. Double-check that the metal key itself has been properly reinserted and that the key button still functions.

Step 5: Test Your New Battery

You’re all finished! Before putting the key to use, test to make sure that the new battery is working properly. Press the buttons on the key to see if it locks and unlocks your car as it should.

• Remember to dispose of the old battery properly. Do not throw it in the trash!
• If you are uncertain about your ability to change the battery yourself, don’t hesitate to take your car key to a professional for help.

Step 1: Identify the Type of Key

Look for Key Number

Locate the key number on your key. The key number is a combination of letters and numbers usually found on the key tag or in the owner’s manual. This number indicates the type of key you have.

Check the Key Shape and Size

Check the shape and size of your key. Honda offers different key shapes for different models. Make sure you have the correct key for your car.

Match the Buttons

If your key has buttons for lock, unlock, trunk, or panic, match the buttons to the picture of the key on the owner’s manual to ensure you have the correct key.

• If you have a traditional key with no buttons, skip to Step 2.
• If you have a key with buttons, continue to the next step to replace the battery.

Step 2: Open the Key Fob

Gather Required Tools and Materials

Before you can change the battery in your Honda car key, you will need to gather some tools and materials. These include a screwdriver, a new battery (CR2032), and your Honda car key.

Locate the Key Fob Seam

Next, you will need to locate the seam on your Honda car key fob. This is where the two halves of the fob meet. Typically, you will find the seam on the bottom side of the key fob.

Use the Screwdriver to Open the Fob

Once you have located the seam, use the screwdriver to gently pry open the two halves of the fob. Be careful not to damage the fob or any of its components while opening it up.

Change the Battery

Now that you have successfully opened the key fob, remove the old battery and replace it with a new CR2032 battery. Be sure to place the new battery in the fob with the positive side facing up.

• Insert the new battery
• Ensure the battery is properly in place
• Close the key fob

Once the new battery is in place, carefully snap the two halves of the fob back together. Make sure the fob is securely closed and test the key to ensure that it is working correctly.

Step 3: Replace the Battery

1. Open the Key Fob

Locate the small release button on the back of the key fob and press it firmly. While holding down the button, pull the key fob apart to reveal the battery compartment.

2. Remove the Old Battery

Once the battery compartment is exposed, carefully remove the old battery. Use a small tool, such as a flathead screwdriver or a pair of tweezers, to gently pry out the battery.

3. Insert the New Battery

Take the new battery and insert it into the battery compartment, making sure to position it correctly according to the markings inside.

4. Reassemble the Key Fob

Carefully align the two halves of the key fob and press them together until they click securely. Test the key fob to ensure that the battery is functioning properly.

5. Dispose of the Old Battery Safely

Remember to dispose of the old battery safely and properly. Do not throw it in the trash, as it is harmful to the environment. Look for a location that accepts batteries for recycling or disposal.

Step 4: Test the Key

Insert the Battery

Take the new battery and insert it back into the key fob. Make sure it is placed in the right orientation as indicated inside the compartment. Push the battery tray back in until it clicks securely in place.

Check if the Key Works

Once the battery is properly installed, test the key by pressing any button. If the key is working properly, you should see a blinking red light on the key fob. The range of the key should also be improved compared to the previous key performance.

• If the key is not working, double-check that the battery is securely in place and properly oriented in the tray, and try again.
• If the key still doesn’t work, the problem might be with the key itself or the car’s remote entry system. In this case, it may be best to contact a Honda dealership or a certified mechanic for further assistance.

Testing the key after replacing the battery ensures that it functions as intended and that you can continue to use it to unlock and lock your vehicle.
