Is your 2012 Honda key fob not working as reliably as it used to? You might be facing a common issue: a dead battery. Fortunately, replacing the battery in your Honda key fob is a straightforward task you can easily do yourself, saving time and money compared to visiting a dealership. This guide will walk you through the simple steps to replace your 2012 Honda key fob battery.
Before you begin, gather these items:
- A new CR1616 3V lithium battery
- A small Phillips head screwdriver
- A soft cloth or towel to protect the key fob
Now, let’s get started with the battery replacement process:
-
Locate the small screw: On the back of your 2012 Honda key fob, you’ll find a small Phillips head screw. This screw secures the two halves of the key fob casing together.
-
Unscrew and open the case: Using your Phillips head screwdriver, carefully remove the screw. It might be a little tight, but apply steady pressure while turning to avoid stripping the screw head. Once the screw is removed, you can gently pry open the two halves of the key fob.
-
Open the inner cassette: Inside the key fob, you’ll see a black plastic cassette containing the electronics and the battery. This cassette is also in two parts. Carefully pry open this inner cassette to access the battery compartment.
-
Remove the old battery: With the inner cassette open, you’ll see the CR1616 battery. Gently remove the old battery from its slot. Take note of the battery orientation – the positive (+) side, usually marked with writing, should be facing down when installed.
-
Insert the new battery: Take your new CR1616 battery and place it into the battery slot. Ensure the positive (+) side is facing down, as it was with the old battery. Use a cloth to press the battery into place, avoiding touching the battery contacts directly with your fingers.
-
Reassemble the key fob: Carefully close the inner cassette until it snaps back together. Then, align the two halves of the key fob casing and press them firmly together.
-
Replace the screw: Finally, reinsert the Phillips head screw and tighten it securely. Be careful not to overtighten, as this could damage the plastic casing.
