Solution

1. Preparation

Gather necessary tools: flathead screwdriver, small Phillips screwdriver, multimeter, and replacement battery (CR2032).
Ensure you are in a well-lit area and have a clean workspace.

2. Open the Key Fob

Use the flathead screwdriver to gently pry apart the key fob casing, starting at the seam.
Be cautious to avoid damaging the casing or internal components.

3. Replace the Battery

Remove the old battery from the key fob carefully.
Insert the new CR2032 battery, ensuring the positive side (+) is facing up.
Check for corrosion or debris in the battery compartment and clean if necessary.

4. Reassemble the Key Fob

Align the two halves of the key fob and press them together until they snap securely.
Ensure all buttons operate freely and that the fob feels intact.

5. Reprogram the Key Fob (if necessary)

Insert the key into the ignition and turn it to the "On" position without starting the engine.
Turn the key back to the "Off" position and remove it.
Press any button on the key fob within 10 seconds to complete the programming.
Turn the ignition to "On" again to check if the key fob now operates.
