Remove the door trim panel and the plastic watershield. Reach inside the door and disconnect the control links from the latch. Mark the location of the door latch prior to removal and take out the latch retaining screws from the end of the door, noting that on 1997 and later models there is only one latch screw. Detach the door latch, and if equipped with power door locks, remove the door lock solenoid. For installation, align the door latch and securely tighten the door latch screws. Through the door inside access hole, remove the outside handle retention bolts or nuts, and on 1995 and later models, take out the lock cylinder electrical switch retainer and the switch. Remove the control rod from the lock cylinder, then use pliers or a screwdriver to pry the retaining clip upwards and off of the lock cylinder. Pull the outside handle and lock cylinder from the door. For installation, follow the reverse process. The door key cylinder electrical switch may be tested if necessary without removal; disconnect the electrical connector and check that the electrical continuity between the terminals is 0 ohms (no resistance) when in the unlocked position, and 1 K-ohm when in the locked position.
