What method can Carola use to bind the car lock reminder to the mobile phone?

Carola can use the remote control key to open the car lock horn and bind the car lock reminder to the mobile phone.

Corolla ensures that the vehicle functions normally and can start running normally, so that you can put the vehicle in a relatively empty place, get off the bus, lock the vehicle with the remote control key, and then stay away from the vehicle. Press the unlock key and lock key at the same time, and you will hear the horn ring for three seconds. At this time, your corolla is equipped with the functions of locking the car and whistling.

If, after three seconds, the horn doesn't make any sound, but just flashes, then press the unlock key and lock key again at the same time, and then hold it for three seconds, and you will hear the lock horn ring.
