The signal works even when the ignition key is inserted. It may turn off at some time or sound while the door is open. It depends on the year of the car.
It's possible to disable the annoying signal. The central console and air ducts have to be dismantled. Behind the front panel is a black box with a white sticker. You can find it by sound when you open the door. There is a board box inside the box. To get rid of the annoying sound, you need to cut the path leading to the speaker and collect everything backwards.
