Step-by-Step Process
Step 1:
Insert a spudger into the gap in the casing.
Gently twist or wiggle the tool to separate the two halves of the casing.
Step 2:

Step 3:
Use a spudger to gently lift the battery casing.
Slide the pointed end of a spudger tip under the circular battery and carefully lift it out.
Step 4:
Carefully remove the motherboard connected to the battery.
Hold the edges of the board to avoid touching any electronic components.
Set the motherboard aside on a clean, static-free surface.
Step 5:
Remove the old battery. If needed, gently open the metal holder securing it in place.
Use your finger to slide the battery out of the compartment.
If the battery is difficult to remove, use a pair of tweezers to lift it out carefully.
Step 6:
Insert the new battery into the holder. If needed, close the metal clip to secure it in place.
Use a pair of tweezers if necessary to help position the battery.
Ensure the battery slides smoothly back into place.

Press the battery and internal components firmly into the key fob casing.
Ensure the casing halves are properly aligned before closing.
