    Q:
    How to remove the Door Handle, Door Latch Assembly and Door Lock Cylinder on Chevrolet K1500? Posted by Rouven B.
    A:
    To remove the door latch, take off the door trim panel and door module. Disconnect the rods from the latch and remove its mounting screws. For the inside handle, drill out its rivets, pull it out, and detach the control rods. For the lock cylinder and outside handle, after removing the door trim and water deflector, remove the window glass assembly. Disconnect control rods, remove handle mounting screws, and extract the lock cylinder and handle. Reinstall in the reverse order.
