How to Install a Honda Civic Door Lock

There may come a time when you must install a new lock on the doors of your Honda Civic. The lock is a solid cylinder within the door that connects to the door latch. Open up the door by removing the inner trim panel to take out the old lock. Install locks on all doors, or else you'll end up needing different keys for different doors.

Instructions

1

Raise the window all the way within the door, so it won't get in the way. Remove the window crank, if equipped, by inserting a special tool or a wire hook behind it to disengage the clip.

2

Remove the trim covers for the inside door handle, the pull handle and the mirror; these will all require a trim removal tool or small flat-head screwdriver. Remove the handle from the door by pulling out the mounting screws and disconnecting the electrical connector, then remove the screws and electrical connector behind the pull handle.

3

Remove the door's trim panel by inserting the trim tool behind the panel at the bottom and working around the panel to release the fasteners. Lift the panel up and off the door, disconnect any electrical connectors behind it and peel back the plastic protective water shield from the door.

4

Disconnect the rods connecting the outside handle to the latch and the door lock to the latch. Both of these have plastic clips to disengage by reaching through the access hole in the door.

5

Disengage the clip for the lock cylinder, and remove it from the handle and the door.

6

Install the new lock cylinder in the door and connect its clip, then reconnect the rods that link the latch to the lock and the handle.

7

Reconnect the door's inner trim panel in the reverse order of installation.
