Remove the door panel
Pry up the window switch and unplug it, then remove the pull and handle trim and their screws. Release the panel clips, lift the panel away, and unplug the courtesy light.
Disconnect the interior handle cables
Remove the interior handle fastener and slide the handle from the door. Unclip both cable ends and free their sheaths from the handle.
Remove the old lock cylinder
Carefully peel back the vapor barrier. Release the cylinder rod clip, remove the access plug, loosen the captured retaining screw, and slide the cylinder from the door.
Install the replacement cylinder
Seat the new cylinder in the door and tighten its retaining screw. Reconnect the lock rod clip and reinstall the access plug, then reseal the vapor barrier.
Reconnect cables and interior handle
Route each cable into its correct handle slot and confirm its retaining clip locks. Reinstall the interior handle and secure its fastener.
Reinstall the door panel and test
Reconnect the courtesy light and window switch, hang the panel, and press its clips into place. Reinstall trim and screws, then test the key, lock, latch, and window.
