Solution

1. Preparation

Gather the necessary tools: a small flat-head screwdriver, a new battery (typically CR2032 for Toyota key fobs), and a key fob programming tool if required.
Ensure the vehicle is in a secure environment to avoid accidental locking.

2. Replace the Battery

Use the small flat-head screwdriver to carefully pry open the key fob casing.
Remove the old battery and note the orientation (positive and negative sides).
Insert the new battery into the key fob, ensuring it is positioned correctly.
Reassemble the key fob casing by snapping it back together securely.

3. Reset the Key Fob (if necessary)

Sit inside the vehicle with all doors closed.
Insert the key into the ignition and turn it to the "On" position (do not start the engine) and then back to "Off" five times within 10 seconds.
Leave the key in the "On" position after the last turn.
Press any button on the key fob for about one second. The doors should lock and unlock, indicating successful programming.

4. Test the Key Fob

Step outside the vehicle and ensure all doors are closed.
Press the lock and unlock buttons on the key fob to confirm it operates correctly.
Test any additional features, such as remote start or trunk release.
