Park the car on level ground. Open the door. Slowly close the door and watch the front and rear pins as they enter the guides and lock. As the door swings down and inward the pins should be centered in the guides and enter the lock without hitting the sides. This is difficult to see without a flashlight.If you can feel the door hit the pins before it latches then you need to adjust the pins. To adjust loosen the pins (one at a time) and move it JUST A LITLE BIT. Make small adjustments till you get it right then do the other pin. Go back and forth doing each pin on 1 door till you get it as good as you can. If you find you can't adjust it enough in 1 direction you will have to remove some fiberglass to get more room to adjust the pin. Make sure you get them tight as if they loosen it could jam the door. Sometimes you need to put a washer under a pin to get it to line up better into the lock without catching on the head of the pin. The two main things are to PARK ON LEVEL GROUND and MAKE LITTLE ADJUSTMENTS. The locks have two locking positions, if the front lock only hits on the first position and the rear on the second the door will jam which is why it is important for the two locks to lock together. When a pin is out of alignment 1 lock is in the first position and the other is in the second. This is made worse when not on level ground. Lockzilla cannot help, this must be corrected before Lockzilla will work correctly.
