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.

Remove the door trim panel and watershield, then close the window completely. Disconnect the link rods from the latch. For power door lock models, disconnect the electrical connector from the door lock motor. Remove the three mounting screws from the end of the door, using an impact-type screwdriver if necessary, and a Torx-head driver for the door latch screws. Detach the clips from the control rods and remove the latch from the door by unsnapping the clip from the rod and pulling the rod out of the lever. Place the latch in position, install the screws, and tighten them securely. Connect the link rods to the latch. Disconnect the link and electrical connector, remove the lock cylinder clip retainer, and withdraw the lock cylinder from the door handle assembly by pushing off the clip at its base. Installation is the reverse of removal. Disconnect the link, remove the mounting bolts, and detach the handle from the door, which is retained by two bolts. Place the handle in position, attach the links, and install the bolts, tightening them securely.

To remove the outside handle, disconnect the cable(s) from the negative battery terminal(s) and remove the carrier plate. Disconnect the two control rods from the handle and remove the door handle bolts from the inside of the door, then remove the handle.
