You need a little pin tool that is strong enough to depress a metal tab. A thick paperclip sometimes works.

Thanks.   I see no place to insert this pin though, do you need to pull the cluster to access this magical pin?  I see on other forums you turn key to "1" which then reveals a hole but on my 6.9 I cannot see any access from the front.  Hmm...

It's located at about the 1 or 2 o'clock position on the outer perimeter of the silver barrel between the barrel and the round black piece of trim.  Yes, you turn to position 1, insert the tool, unscrew the black barrel, and both pieces will come out together.

OK, apologies for having somewhat hijacked this thread ;D

I took a pic of what I am seeing, I simply do not see any hole where you can insert said pin???

Looks like I might need this tool then?

in the first post I linked a video I made of the process, its quite evident.  your barrel looks like a 123 unit, not a 116 one?  The large black surround I thought was only on 123s, perhaps more knowledgeable people are aware.

Harv, I tend not to click on Uncle Kents videos, it tends to be like opening the door to a door knocker - they will ask for money!

Indeed I scoped out your video, nice and clear however for sure I have a different setup than yours.  Could be that mine was replaced but there is no pin opening on the face.

ill take some pics of my spares, as I have a bout 4 barrels like yours lying around and dont recall stripping 4 123s!  But I just dont recall seeing these different types of barrels on 116s (maybe most I wrecked were later Australian ones with the last of the three barrels as per UTN)

I agree that a different type of lock cylinder and barrel has been installed in the past.  Two things to point out:

1) When the key is in position 1, this type of black barrel will simply pull off.  Once removed as far as it'll go with the key in the lock cylinder, you turn the key to the off position, extract the key with the black plastic barrel.  Afterward, reinstall the key, turn to position 1, and the lock cylinder will then come out either on its own or after sticking a paperclip into the elusive hole which should be visible with the plastic barrel removed. 

2) Early ignition lock assemblies that had a chrome plated barrel is what may have been used on your car.  However, the chrome plated barrels are no longer available, and have been superseded by the plastic one.  So you either have an early W116 assembly with the plastic barrel or a later W123/R107 assembly with the plastic barrel.

OK great thanks, I did try to get that black plastic cover off with key in "1" but it looks like it is pretty stuck on there.  Will report progress.

The plot thickens, or maybe it's my brain thickness ???  I removed the cover but still see no pin opening.  Only a circlip/snap ring.  I rotated the ring along it's whole path and did not see a hole for where a pin would be able to go in.  Hmmm...I really do not want to mess this up and get stuck with a key not going in or not turning the ignition, might just have to leave well enough alone...Pic attached for what it's worth:

Is the pin being confused with a circlip? Looking at the pic the part around the barrel is a circlip and there is enough space around it to use a appropriate circlip removal tool to remove? Odd how it's set up but if circlip removed at least the outer part would be free to be pulled out?

The circlip only holds the core in.  For this type, there will be a little spring loaded pin you push in on the area behind the instrument panel.  Rather than trying to explain in detail in another short novel, I'll try to get some pictures to post later today.
