Which one is the micro switch on the Song Pro key?

[BradyLee]

The micro switch is a small switch integrated in the ignition lock. After pulling out the key, it sends a signal to the body computer that the key has left. If the micro switch malfunctions, it may cause the central locking system to fail to lock. Smart Key: With the smart key in your pocket and approaching the car door, the vehicle will automatically sense it. Simply press the micro switch on the door handle to unlock and enter the vehicle. Button Press: Press the unlock button on the smart key to remotely unlock the car, which is a common unlocking method for general vehicles. There is also a more advanced unlocking method - BYD owners can download the Cloud Service App on their phones, which pairs one-to-one with the vehicle. You can remotely unlock the car, start the engine, turn on the air conditioning, etc. using your phone. So don't worry if you forget your key, as long as you have your phone, you can drive. Moreover, BYD is about to launch a full-scenario digital key.
