Replacement ignition switch will not have that hammer lock thing in the middle. Don't worry about that at all. Just put it on.

I have bought ignition switch from factory... no center lock... I then bought entire l*** assembly... again. no center lock either. Now I just bought another one... same story.

Just put it on!

Thanks again Tiger. You're always on the job, I'm happy to say.

Installing the switch was very easy but I now have trouble with the locks.

After I installed the switch, I put the steering lock back into its holder and the
pin popped out through the hole. Then I followed the instructions for reassembling the lock. e.g. putting it into its screw cap with the detent aligned with the slot inside the cap. Next I inserted the key, turned it to position 1 and pushed the release wire through the little hole on the rim all the way in. I looked at it from the back of the lock and the pin was in the correct place.

I aligned the lock with its holder, placed it in its slot and screwed the cap until it reached the end. Next I pulled the wire out and rotated back the cap until the detent released - it was just one turn. The key was still in position 1 but it would not turn.

On a few occasions I found the car in a similar position with the key stuck at position 0 and just jerking the steering wheel released it and allowed it to turn and start the car. The present situation seems to be the reverse.

I pushed the car back and forth a little (with the key in position 1) while turning the steering wheel and it was not locked at all.

Seems like I messed it up somewhere.

The messup was the new and incorrect ignition switch. I replaced it
with the old switch and the steering lock and the key are now working again.
I expect a replacement switch in a few days.

I think I'm living in a circus. It appears that I have another incorrect ignition
switch.

Now I know of 3 varieties:

What is different in the three is what appears in the middle of the pins and the metal casing (shroud) around the outside. The pins and their numbers are the same on all.

1 A slot with a round white piece with a diagonal slot across it. This piece comes up to about the height of the base of the pins. It has a metal shroud around the outside that is a little higher than the pins. This was the first one I recieved.
2 No slot but a plastic spike (the section across it is a semi cylinder), that is slightly taller than the pins, and it does NOT rotate. - has no shroud. This is the second I have received.
3 A slot with light colored piece that looks like a small hammer. The handle goes down into the slot and the top of the head is about the height of the pins. This is the one I have - it also has a shroud.

Are these familiar to anyone?

TIA

Thank you Tiger.

The one that is not working for me (# 1 in the above list) is at:

Both switches are the same except the lower one is "after market."

The upper one gives a good view and is the switch I have been working on. Click to enlarge. Notice the number at the base - 202 545 0104 and the MBZ star. The original part has the number 126 462 0093 at the base, and also with the MBZ star. In both cases the numbers are molded or stamped into the metal at the base.

My Chassis and Body Manual manual for 123123, Vol 1 page 46.4-640/12 F3
shows the electric plug that attaches to the steering lock and the hole in that
plug is semi circular. This is apparently the original one and the switch in that case
has the semi-circular spike to fit that hole - # 2 on the above list of three.
In my version that semi-circular hole became a slot to accomodate the "hammer-head" of the switch.

BTW, how does one lubricate the steering lock mechanism. I have the lock part puffed
up well with graphite. I know I could use machine oil or ATF. It seems that it does not come apart, so grease doesn't look an option.

Have a great weekend :-)
