I just removed metal plate that holds door lock and power windos It looks like lock is hold by three plastic screws attached to metal

looking screws. How i can remove them so i can install new lock ?

 

Lock is held in place by ONE screw.
Hole on the side of the door, where it makes contact with the door jam, a long torx driver is required to reach it, goes in at a sideways angle.
Sorry I forget which size. You need to feel around for it.
Leave the torx driver in the door when you remove the
lock to keep the screw from falling into the door. It will come out with the plastic surround. Then the lock/sensor assembly just snaps out of the plastic.
You should be able to find photo's around somewhere.
Lots of threads in the 203 forum, same concept, related to the sensor.

 

It seems the black part has door handle part attached to it. SO you guys dont remove the black stuff from metal frame.

 

Lets move this whole conversation to your other thread.
