This video shows you how to change the lock actuator on a 2004-2006 Acura TSX. The same procedure can be used on a 2003-2007 Honda Accord and 2004-2008 Acura TL.

Parts used:
Dorman Lock Actuator (Part# 746-367) – $18

Tools used:
Plastic Door Panel Removers – $16
Small Standard Screw Driver
#1 Phillips Screw Driver
#3 Phillips Screw Driver
10mm wrench or socket

You may also want the door clip retainers in case they cannot be reused after removing the door panel. You can find those on Amazon:

Important Note:
Do not use an impact driver to remove the screws holding the latch assembly to end of door. If you do, you might crease the door like I did. You can see it happen at 4:10 in the video. Use a #3 Phillips Screwdriver instead.

    So glad I found this video to fix my 2005 Honda Accord. My boyfriend tried twice this past weekend for many hours to replace the actuator but he didn’t have something just right, so it wouldn’t lock the driver’s door, even though the lock was in locked down position. Even as it looked locked, you could still pull the outside handle and it would always open. So frustrated, until I spent all day today trying to find a schematic or anything of pictures to lead us to correct it, then I stumbled across this in YouTube! You even have the step-by-step that I printed out for him to use. So Great!!! Thanks so much again!! I will feel better to secure my car again! PS: I really surprised by boyfriend that I found how to correct this problem, by video and step by step…LOL! Perseverance wins and it pays to not give up, as he did. He was shocked! I am so grateful to you!

    Thank you so much, instructions were (almost) perfect. Only thing that I think wasn’t specifically mentioned was removing the 10mm window guide bolt before trying to remove the door latch
