Help - door locks given up the ghost

I bought an mk3 golf last summer with the same problem. The part that was broken was called the door lock eccentric or something. It was possible on my car to pull the entire lock barrel out of the car. Cost about £1 each from German&Swedish. I took the inner door trim off my car to replace the part. It makes realigning the door handle easier afterwards. There is also a hex bolt on the side of the door that needs removing so that the outer door handle can be pulled away from the car. The replacement part has a hook at one end that attaches to the lock barrel and a flat end at the other that actually engages with the locking mechanism. There is round piece of metal with a spring that covers the hook part and holds it in place. Assemble the lock barrel, eccentric and the round piece then fit the lock barrel into the hole in the door handle. The door handle then needs fitting back to the car. This is where removing the door trim helped as it needs guiding in carefully. The flat part of the eccentric should then engage with the lock mechanism if it is aligned correctly. Refit the hex bolt making sure that the door handle is not sticking out slightly.

Hope this makes some sort of sense.

Thanks Stephen, I'll take off the inner door trim and take a look to see if this is the problem.
