How to lock the door after leaving the car?

1. Press the latch to lock the door before the cab closes (of course, pressing the latch before closing some cars will automatically raise the latch, except this peace).

2. When the door is closed, lock the driver's door with the key (with central control). If there is no central control, the co-pilot door needs to be locked again (the method in the back row is 1).

If your car is good enough, it is ok to lock it automatically. You can install a scanning system-lock the door and close the window automatically when your key is at a certain distance from the car and your door is unlocked.
