The black plastic piece is the noise and impact damper. If it had gone out of position, the lock would not latch.
If it can be pushed back into position, it would last for a while but if it is worn, you might have to replace the latch unit. Then you need to remove the door panel to take the latch out, involves taking out quite a number of things.
