If you can't open the front door in any way, you can only say that your car's door lock is broken and you have to go through the repair.

Therefore, the door lock must be able to be unlocked normally after the disorder has occurred, which is a requirement for the car to meet. Therefore, the probability that any vehicle door cannot be opened after the vehicle falls into the water is quite proud.
