Lock cylinder removal

I posted this in the "General" category because its probably generic to many models and not just the 124. I hope someone can help.

Yesterday my 124 gave me trouble when I tried to turn the ignition key off. The car shut off but the key didn't go back to the full off position. The steering wheel was somewhat locked but it didn't feel the same as it normally does when it locks. There seemed to be more travel from one direction to the other. After a few frantic minutes jiggling the key up and down while trying to turn it off, it finally returned to the full off position and I could get the key out. When I tried to start the car the key wouldn't get out of the full off position. I jiggled it again and it moved and the car started.

Afterwards I shot some graphite into the lock cylinder and worked the key in and out. It still wasn't right so I switched to my spare key. It wasn't perfect with the spare key but the ignition switch works much better now. This is just a problem waiting to strand me so I want to get to the bottom of it.

The archives seem to indicate I am having a lock cylinder problem. If so, what is the procedure for removing it? Thanks for any help.

You got two choices:
1. Get the actual tumbler for your keys from the dealer
a. Have them install it
b. Install it yourself
2. Get a tumbler with its own set of keys. This means you will have to use your old keys to gain access to the car but the new ones to start the car.

To remove the tumbler you need to remove the bezel surround. To do so you need to use your key to turn your iginition to the first position. You have to do this.
Once in that position insert a pin or a paperclip that has a 45 degree cut on the end in the little hole between the bezel and the tumbler. Puch the pin in and you will feel that it is pushing a spring of some sort.
Turn the bezel while keeping the pin in the hole. This will keep the bezel locking mechanism from being active. Turn the bezel counter clockwise until it comes off from the tumbler. Pull the whole mechanism out.

Do the reverse process with the new tumbler.

I did the same thing a month ago and I ordered my tumbler from Ron at Germanstar (yes our mod, and he was very helpful).

Good luck

EVERY W124 ignition switch eventually fails.

It's VERY silly not to get a matching-key replacement from your dealer.

You'll need proof of ownership.

Thanks guys for the responses. I appreciate the help as this is one of those repairs that is near impossible to figure out without a hint. I'll price a correct lock cylinder from M/B and decide once the "damage" is assessed.

lkchris and Professor,

Thanks for the help. I purchased a cylinder with the matching keycode from MB as well as another key. The whole thing was just under $100 and quite worth it.

However, I tried to follow the instructions and have not had success in getting the lock bezel off. I can use some guidance here.

There are two holes on the face of the tumbler that a pin/tool could be inserted through. I am using the upper most one (in the "2 o'clock" position when the key is turned to position 1 in the Professor's instructions. Is this right?

Also, what am I actually trying to release with the pin/tool ? Am I depressing a spring loaded plunger or is there a different objective? So far I am getting nowhere; any additional help will be appreciated.
