The lock barrel is with the handle, its a bit of a nuisance to get out, there are holes in the door which line up with the bolts, you will need a extension to get to them.the key goes about 80 degrees in either direction to lock and unlock. one of the handle bolts is on a angle into the door.

 

I did notice two holes on the inside metal panel of the door covered with black plastic plugs, once I removed them, I could clearly see the nut on the bottom of the handle, but some black plastic stuff covers the view to the upper part of the handle through upper hole. So, what is that black plastic piece there and how do I remove it in order to get access to the upper nut on the handle?

So, are you saying that if the lock barrel rotates all around then the complete handle with the lock barrel has to be replaced but other than that it should be OK? Or is there any other reason for the lock barrel can be rotated around?

If I have to get a handle replacement I don't want to remove the old one before I got the new one because I don't want the car park on the street with no door handles. But if this problem could be fixed by taking some stuff apart, I'll go ahead and do it.

 

you need to remove the handle to get the barrel out, they are separate so you dont need to replace the handle. not sure what stops the barrel rotating, assuming its the rods that are attached to the back which control the overall movement. if its going round in a circle it could be broken inside. why does your central locking not work on the remote ??

 

It would be great if the rods i.e. or the door lock mechanism itself would limit the circular movement of the lock barrel in the handle, unfortunately I don't know how to remove the handle since I cannot see straight access to the upper nut inside the door.

This is a 2001 Vivaro and it doesn't have a remotely controlled central lock unfortunately. The ignition key itself has only an immobilizer chip inside but no alarm or central lock buttons. It is true, that if you lock or unlock the driver's side door it also activates the passenger side door lock, I forgot to check whether the passenger side door lock also controls the driver's side one. Especially since yesterday I reattached a 2nd linkage rod to the door knob on the driver's side that must have come loose long time ago.

So, it seems like that if I want to see how the whole enchilada works, I have to remove the door lock, the handle with the lock barrel and the central lock switch since I do have a PDF version of the service manual but it only has some mickey-mouse drawings in it instead of photos.

 

I just looked at the passenger side door lock, it does unlock but won't lock the driver's side door by using the key but it does both by using the knob. So, that seems like a linkage problem as well, I am not sure.

 

Well, I started this thread in February but I didn't have time work on this problem until today. I managed to remove the outside door handle from the door but I just cannot figure out how to remove the lock and the inner part of the door handle that also holds the cylinder lock. Of course, I already removed the three torx bolts that hold the lock but since the lock is connected to the cylinder with a linkage I am unable to remove it.

First of all, I cannot see how I can remove the linking rod between the lock and the cylinder, my other dilemma is that even if I already disconnected that linkage, I don't see how I can remove the inner part of the door handle that holds the cylinder as well. There isn't seem to be enough space to remove it, if the sliding rail of the window wouldn't be there, that would solve the problem, I just cannot believe that that sliding rail has to be removed for replacing a cylinder lock.

Can anyone help?
