Step-by-Step Instructions
Step 1: Open the Key Fob
First, examine the key ring area at the top of the key fob. You’ll notice a small indentation in the plastic. Insert the flathead screwdriver into this indentation and give it a twist. This action will start to open the key fob.
Continue working your way down the opening by twisting the screwdriver until the back cover comes off easily. Set the cover aside.
Step 2: Remove the Battery Housing
Inside the key fob, you’ll find a small component that houses the battery. Gently dump this component out and take a closer look. You’ll see small latches or pieces of plastic that hold the battery housing together.
Using the flathead screwdriver, carefully push and wiggle each latch to unlock the housing. It may not feel like much at first, but you’ll eventually move past the small piece holding it in place. Usually, by the third latch, the housing will start to come loose. Continue until all latches are free, and then pull the housing apart.
Step 3: Replace the Battery
With the housing open, you’ll see the CR1620 battery. Note that the positive side, which has the text and battery information, should be facing down when you replace it.
Using the flathead screwdriver, gently lift the old battery out from the top left corner. Dispose of the old battery properly. Place the new CR1620 battery into the housing, ensuring the positive side is facing down. Click it into place.
Step 4: Reassemble the Key Fob
Now that the new battery is in place, reassemble the battery housing by clicking it back together. Ensure it is secure and looks good.
Place the housing back inside the key fob, making sure it sits flush. Click the back cover into place, ensuring it is secure and not open.
