Nissan K0600-0W001 Cylinder Set-Back Door Lock

First, detach the electrical connector from the lock cylinder, if your vehicle is equipped with one. Then, using a screwdriver or a pair of pliers, pry the lock cylinder retaining clip off the lock. Pull the lock outward to disengage it from the door and the lock cylinder control rod. On some models, you may also need to disengage the clip securing the control rod to the lock cylinder.
