I tried everything as far as the locking system. Is this something electric.

forward and check alignment of the door to see if they align

It seems that the lock is pooched. Usually when he goes, the only solution is to replace it.

I know what's wrong-You misspelled Mercedes!

check it when the door is closed as u see 3 flashes at lock if no check switch door contact is possible when someone unbuckle the seat belt was caught in the ignition and location on the switch is on the side b pillar out, you can see when the door is opened to check the two parties is possible is that I know ..
