Replacing the battery in your 2017 Honda Accord key fob is a straightforward task that saves time and money compared to visiting a dealer. The key fob uses a common CR2032 3V lithium coin cell, a battery type readily available at pharmacies, grocery stores, and online retailers. This guide provides clear, step-by-step instructions to help you complete the process without damaging the fob or losing programmed remotes.
Identifying the Correct Battery for Your 2017 Accord
Ensuring you have the right component is the most critical first step. The 2017 Honda Accord key fob is specifically designed to operate with a CR2032 coin cell battery. This designation refers to the battery's chemistry, size, and voltage. Using a different type or size can result in a non-functional fob or potential damage to the internal circuitry, so verify the label before purchasing.
Tools Required for the Replacement
You do not need a specialized toolkit for this maintenance task. Gathering a few common household items will prepare you for a smooth procedure. The primary tool required is a small, flat-head screwdriver or a thin coin, which will be used to pry open the fob's casing. A clean workspace and good lighting will also help prevent losing small parts.
Recommended Toolkit
Small flat-head screwdriver or a sturdy coin (like a quarter)
New CR2032 battery (3V lithium coin cell)
Soft cloth or towel to protect the fob during the process
Clean workspace with good lighting
Step-by-Step Battery Replacement Process
With the correct battery and tools ready, you can begin the replacement. The design of the 2017 Accord fob allows for easy access without breaking tabs or screws. The process involves carefully separating the two halves of the key fob to remove the old battery and insert the new one.
Opening the Key Fob
Start by locating the small seam along the long edge of the fob where the two halves meet. Insert the tip of your screwdriver or coin into this seam and apply gentle pressure to pop the casing open. Work slowly around the perimeter to avoid cracking the plastic housing.
Handling the Internal Components
Once the fob is open, you will see the battery secured in place by a metal spring clip. It is important to handle these internal components gently to maintain the integrity of the device. Before removing the old battery, take a moment to note its orientation, specifically which side is facing up, to ensure the new battery is installed correctly.
Removing the Old Battery
Using the screwdriver or your fingernail, lift the metal spring clip upward to release the old CR2032 battery. Carefully remove the battery and dispose of it properly according to local electronic waste guidelines. Avoid puncturing the old battery, as it may contain materials that should be handled with care. Installing the New Battery and Reassembly Installing the new battery is the reverse of removal. Place the fresh CR2032 battery into the slot with the correct orientation, ensuring the positive side matches the position of the old battery. Then, press the metal spring clip back down firmly to secure the battery and establish a proper electrical connection.
Installing the New Battery and Reassembly
Testing the Key Fob
Before snapping the two halves of the fob back together, test the device to confirm it is working. Stand close to the vehicle and press the lock or unlock button. If the doors respond immediately, the replacement was successful. Reassemble the fob by aligning the seams and pressing the halves firmly until they click back into place.
