Chrysler 4778123 Door Cylinder Lock

This procedure applies to both the front and rear doors. To remove the latch, first take off the door trim panel, ensuring that on vehicles with electric windows, the window is closed before disconnecting the electrical connectors. For manual windows, install the window crank without the retaining clip and roll up the window. If removing a rear door latch, also remove the window glass lower rear run channel. Next, disconnect the lock cylinder, lock button, and latch release operating rods from the door latch. For vehicles with power door locks, disconnect the electrical connector from the door lock motor. Remove the three mounting screws from the end of the door and take out the door latch. For installation, position the latch, install the screws, and tighten them securely. Connect the operating rods to the latch and secure with retaining clips, ensuring not to close the door until the latch is properly adjusted to avoid it not reopening. To adjust, insert a hex-wrench through the elongated hole near the latch, engage it in the socket head screw on the door latch linkage, and loosen it a couple of turns. Lift the outside door handle all the way up and then release it, followed by tightening the socket head screw and checking door operation. For the outside handle removal, take off the door trim panel, close the window on electric window vehicles, and for manual windows, roll up the window with the crank.

Installation is the reverse of removal. For the lock cylinder, first remove the outside door handle, detach the operating rod retaining clip and operating rod from the lock cylinder, and if equipped with the Vehicle Theft Security System, remove the illuminated entry switch wiring clip and disconnect the electrical connector.
