Q: How to remove and install the Door Handle,Door Latch Assembly and Door Lock Cylinder on Toyota Prius?
A: First of all, it is necessary to eject the internal panel of the door, and the plastic which is called watershield. To open the door for models before 2009, remove the control links from the latches through these holes, after which you have to take out the screws that hold the latches at the end of the door to get the latches out, and the door lock solenoids, if any. For cars that are 2010 and newer, disconnect the wire from the linkage part of the latch; take out the screws at the edge of the door and while still connected to the cables, slide the latch assembly down. Next, for the lock cylinder and outside handle on 2009 and earlier models, pull the lock cylinder and the outside handle toward the door and turn each control rod counter clockwise to disconnect; push the lock cover and the cylinder back toward the rear of vehicle taking care not to lose the small translucent washer while loosening the screw; this will pull the lock cover and cylinder off the door and ultimately remove the outside handle by disconnecting the control rod and If doing an outside handle assembly replacement, the rod and the door operating cable should be moved to the new handle, and then you take out the retaining clip or the bolt that retains the lock cylinder. First, look for hole plug on newer 2010 models, then remove this piece, then take the captive screw which is T30 Torx socket size and the outside handle cover and lock cylinder on 2010 and the following models. Inside the door there are two claws to let go of, and the wiring of the handle need to be disconnected, after which the release lever should help to break a connection between the handle and the door with the help of which to slide the handle assembly out. And lastly, fully release the retaining screw for the inside handle, then you rotate the handle until it comes out, you disconnect cables, and for the removal of the handle form the door, it is removed in the way you put it in the whole process.
