How to remove and install Trunk Latch and Lock Cylinder on Kia Optima?

If the trunk latch fails to operate with the remote release, first check that the lock mechanism at the latch is set to the Unlock position. To address the trunk lid latch, open the trunk and remove the trunk lid trim panel. Disconnect the electrical connector for the power lock, remove the plastic cover, and disconnect the outside trunk release handle-to-latch cable, followed by disconnecting the trunk lock cylinder-to-latch rod. All trunk lid lock rods are attached by plastic clips, which can be removed by unsnapping the portion engaging the connecting rod and pulling the rod out of its locating hole. Next, remove the fasteners securing the latch to the trunk lid and take out the latch assembly, with installation being the reverse of removal. For the trunk lid lock cylinder, open the trunk and remove the trunk lid trim panel. Through the large access hole, disengage the outside trunk lid lock cylinder-to-latch rod, and again, remove the plastic clips by unsnapping the portion engaging the connecting rod and pulling the rod out of its locating hole. Disconnect the wiring harness, remove the lock cylinder mounting fasteners, and take out the lock cylinder, with installation being the reverse of removal.
