Exercise caution and wear gloves when removing and replacing door handles and latch assemblies. For 2007 and earlier models, raise the window, remove the door trim panel and watershield. Inside the door, remove the latch assembly screw and handle cover. Slide the handle towards the rear, remove insulators, and release the clip to move the interior handle aside. Then, remove latch screws and disconnect the electrical connector. Slide the latch assembly towards the front, remove the anti-theft guard, and disconnect the exterior handle rod. Installation is the reverse. For rear handles and latch assembly, remove the electrical connector, glass top run bolts, and separate the run from the door. Remove handle screws, cover, and slide the handle towards the rear. Inside, remove the screw and loosen the control assembly. Disconnect the actuating rod, remove latch screws, and remove the rear latch. Release the conduit and disconnect the interior handle cable. Remove the handle assembly by prying the clips and separating it from the door. Installation is the reverse. For 2008 and later models, the process differs slightly with additional steps, but caution and attention to detail remain essential.

If you have one, use it to raise the window all the way up, then you can take off the door trim panel, and the watershield. Remove the door latch control to cylinder rod connection. Carefully push the cylinder retainer clip away from the lock cylinder and door using a pair of pliers, and and then withdraw the lock cylinder form the door. Fit the lock cylinder with the help of door opening from outside and lock the retainer clip in place. Again reconnect the lock cylinder rod-to-door latch control, the lock should work properly, then install the watershield and the door trim panel.

Remove the screws securing the latch to the door (Remove the latch retaining screws from the end of the door).

The process differs slightly, with additional steps for door handles, front door latch, lock cylinder, and rear door latch. However, the fundamental caution and attention to detail remain essential throughout the procedure.

Working through the large access hole, position the latch as necessary to disengage the outside door handle and outside lock cylinder from the latch rods and the inside handle from the latch cable.
