Is the key turned fully to the first mark? When first turning it will stop half way then turn more to the mark. You should be able to feel the wire compress the spring to retract the locking tab. When it releases the cap can then be unscrewed. If the wire is too thin it may not fully retract.

If inserted correctly the wire will go in approx. 17.55 MM. If the wire only goes in about 9 MM you haven't hit the sweet spot.

People talk about "Position 1" as the right spot but it's essential to ensure that the holes are visible before introducing the u-shaped tool. I had the difficulty you describe until I squirted lithium grease into the little holes and turned the key a few times. Then the tool seemed to go further in that the barrel released.

Thank you for the tip but my RHD 1987 300SL has only one hole needs just a single wire. Please keep the ideas coming. As I am replacing barrel and switch I have sprayed CRC into barrel.
Regards

Key is not in correct position. Key head should be at this spot.

Wire should not go in more than 17.55 MM in any position.

That is as far as the key turns, will not start does not spring back I know problem with spring back is in the switch, when I turn key as far as it goes radio comes on and wire lines up with hole, I will try a LITTLE more force on key and see. Key goes no further than shown in photo does not start and return.
Thank you

I have heard remarks about cutting shroud face off with a Dremel is this a solution (I'd rather not)

I have been where you are. You can try slipping the steering wheel back on and rotating it back and forth while keeping slight pressure on the key. If it ever goes further do not return to off. Other suggestions I received were try a different key, and vibrate. Nothing worked and I ended cutting and grinding for two days with a Dremmel tool. I'll snap a couple of pics later to show how the wire works.

Mercedes W124 Ignition Lock Tumbler Replacement type in

I have looked at the above site (USA) and it appears wire goes goes in a lot further on that particular cylinder, same year as mine. I will go and try rotating S/Wheel.
Thank you 11.30PM Monday 23-3-20 Down under

If this is the video you watched it is not the same tumbler as yours.

Here is what yours looks like

This is a '86-'89 107 tumbler. How it works: The spring loaded block fits in a slot of the black cap. Extended it prevents the cap from turning. The wire causes the block to retract.

If you do end up grinding, cutting, drilling try removing just this area of the cap to expose the area to insert the wire.

Maybe a little larger. You will have to go pretty deep. Luckily new caps are still available.

EDIT: 4/5/2020 WRONG INFORMATION. INSERTING A WIRE WITH THE KEY IN ANY POSITION OTHER THAN ONE WILL NOT CAUSE THE BLOCK TO RETRACT.

It is steel but not hardened like I originally thought. I do think the cap area of the tumbler where the key goes in is hardened.

Rowdie, this is where I'm at, front of barrel/shroud removed much better access to wire passage used thicker wire jiggled for hours still no joy. Any suggestions? I can see down wire channel there does not appear to be any lug to lift.
