How to start XTS when the key fob battery is dead?

Replace the original battery's electronics, specifically the small battery, ensuring the voltage and model number are identical. After removing the car key, take out the mechanical key. To release the mechanical key, press the small button, then you can pull it out.

When my XTS key fob runs out of battery, I first use the small mechanical key blade to unlock the door. There's usually a hidden slot on the key fob – just pry it open to access the door lock. Once inside the car, don't rush to press the start button because the dead key fob can't transmit signals. Locate the key fob detection area inside the vehicle, typically marked by a small symbol under the dashboard near the driver's seat or next to the start button. Press the key fob against this spot like attaching a magnet. Then, step on the brake and press the start button to ignite the engine. Actually, there's a chip inside the key fob that operates using the car's energy, so it works even without a battery. I recommend memorizing the sensor location for next time to avoid panic. Also, the key fob uses a CR2032 battery – keep a spare in your car for easy replacement. It's a 5-minute DIY job – just use a coin to pry open the back cover, but be careful not to lose the small components.
