First, you need to remove the lock striker from the door opening, close the door with the lock striker removed, and verify the proper door fit to the door opening and weatherstrips. Then, please install the lock striker to the door opening, install the lock striker screws retaining the lock striker to the door opening, and use a large flat-bladed tool to rock the striker up and down to loosen the lock striker backing plate from the body. Finally, you should close the door while holding the outside handle in the open position to align the lock striker, open the door, and finish tightening the lock striker screws.
