When installing a new latch, simply close the window and then take off the door trim panel and the watershield. First, if this is the earlier model, unscrew two Torx-head link rods from the latch, then remove the three Torx-head mounting screws if they are overtightened, using an impact-type screwdriver if possible. Closely unscrew the latch then place the new latch and screw it in tightly until they are tightly fixed. Connect the link rods to the latch and ensure that the door will close well, if the latch is an issue, engage the screws and adjust the latch until the door closes properly with the handle flat. After that tighten the linkage adjusting screw with a 5/32-inches hex-head wrench through the adjustment hole, after that, move the squab up in the slot to remove extra Loose from linkage. For the lock cylinder of the outside door handle, it is necessary to disconnect the connecting link and then push the retainer of the key lock cylinder with use of a screwdriver to pull the lock cylinder out of the door and the process of installation is opposite to the mentioned procedure. To remove the outside handle, push down on the end of the remote control link which disengages the latch, unscrew the two nuts on the mounting plate and remove the handle from the door. Last but not the least, position the handle, connect the link and fix the nuts properly on to the Link fixed on Link rod.
