Tools and Materials Needed
Before starting, gather the following tools and materials:
- Small flathead screwdriver
- Two CR2025 batteries
If you don’t have these items, you can easily purchase them online. For example, you can find CR2025 batteries on Amazon.
Step 1: Locate the Indentation
First, find the small indentation on the right side of the key fob. This is where you will insert your tool to open the fob.
Step 2: Open the Key Fob
Using your small flathead screwdriver, gently pry open the key fob at the indentation. If you don’t have a flathead screwdriver, a paper clip can also work. The goal is to create enough leverage to pop open the fob without damaging it.
Step 3: Remove the Old Batteries
Once the key fob is open, you will see two CR2025 batteries stacked on top of each other. Carefully remove them one by one. This step is crucial to ensure you don’t damage the internal components of the key fob.
Step 4: Insert the New Batteries
Take your two new CR2025 batteries and insert them into the key fob. Make sure the positive side, which has the text and plus sign, is facing down. This ensures the batteries are positioned correctly for optimal performance.
Step 5: Close the Key Fob
After the new batteries are in place, line up the two halves of the key fob and squeeze them together until they snap shut. This should be a straightforward process if everything is aligned correctly.
