Hi,

I bought a used 2009 Civic 4 door sedan. I has manual door lock. It's very inconvenient. As is now I have to manual lock or manual open the rear door and the front passenger side. I would like to change it to whenever I close or open the driver side, all door should do the same.

Is it a do it yourself job ? what material do I have to buy ?

What is the procedure ?

I notice that now a minute I start the trip, the rear door automatically locked if they have not been manual locked. That tell me the door already has some sort of door lock motor in them.

any help is greatly appreciated
