I took out the mechanism to inspect it. Using a screw driver I can lock the door. But The key doesn't seem to turn the lock long enough to be able to lock the door.

I'm not totally clear on what you are saying; are you saying, that the lock tumbler will not turn enough degrees to unlock the door? The tumbler could be broken; worn out or need to be lubricated. You could take it to a auto locksmith and see what he can do for you or order a new one from your local vw dealer with your vin number (this way; it will fit your current key).

If you want to try to lubricate it; try a product like this, available at your auto parts store. Most seem to be graphite or silicone based lubricants.

Yes. The tumbler doesn't turn clockwise far enough to trigger the lock. I disassembled the whole cylinder but haven't seen anything unusual. except that the tumbler is loose which I assume is intended to be.

Well, think about how many times; it has been used over the years (probably the original part). It could be just worn or wearing out; I had to replace the tumbler for the ignition switch as it was getting harder to turn and sticking. The new one fixed the problem; that maybe the case with yours. Did you try to lubricate it and did that make a difference?

My passenger side door lock/tumbler is fine but honestly, I hardly ever use it (as I use the remote to unlock the door).

I tried wd40. I don't have a key lock in the passenger side. My ignition is also hard to turn. And I found out an old ignition cylinder in the glove box too.

I fixed my remote now so it's not important.

A graphite lube would be a better lube; a new tumbler would probably be the way to go. I tried to lube my old ignition tumbler but a new replacement, fixed the problem. In the case of the ignition; a new switch and tumbler, removed any stickiness, binding and was a big improvement. Mine were original and just worn out.

Never mind, I bought a remote control so I don't need to use the key for the door anymore.
