190e Door lock tumbler: Can it be separated?
 

I need to replace the driver's door lock. I found a brand new one on Ebay for $75.

Can I exchange the existing tumbler with the new one and thus keep using the original key?

If you use the Ebay lock, you will have to use one key for the door and one key for the ignition. You will save about $75 by using the Ebay lock as a new lock from the Mercedes dealer will be about $150. The difference is that the dealer will use your VIN number to make the tumblers in the door lock match the ignition. You will have to go to the part counter to order in person. My dealer would not take this order over the phone. I think I had to prepay too. My replacement has gone out now and I'm thinking about going to the local car stereo installation shop and get them to install a remote battery operated lock/door opener. I think the price will be around $150 and I won't have to replace the tumbler in the door.

What has failed is the end of the tumbler unit, it broke off. I have been told, read about and can see where there is a small roll pin that can be driven out and use the new nose piece on the old lock tumbler unit and use the old key.

My question, in clarification, is there any other place to separate the unit or even better, can just the lock tumbler be separated from the total unit.

I don't have an answer for that. It does have electric parts in there too as it arms/disarms the alarm. I'd really worry about breaking the new part. You have several options: 1. Just keep the old tumbler in place and lock the doors from the trunk or passenger side. This does get old, but it works. 2. Buy the Ebay tumbler and install it. So what that you have two keys on your key ring, just put a drop of nail polish or Liquid Paper to separate them. If you drove an old Ford or Chevy you'd have a two different keys. 3. Get the dealer key made...4. Get the aftermarket remote kit.
It is a shame that they made those end pieces so fragile. I used JB Weld on mine to repair it and it did last a few weeks, but has broken again. It must have been some cheap soft metal--kinda looks like pewter. Wish they would have used some good hardened steel on that end piece and the star shaped female connector in the door--it looks like plastic. Good luck.

i just swapped mine with the tumbler from the passanger side. since all the locks can be controlled from the driver side anyways.

Unfortunately the passenger side is broken as well .... on closer inspection of the new lock assembly I see two sets of small roller pins. The ones I spoke about earlier, close to the end that is inserted into the door latch mechanism but two closer to the tumbler.

I am wondering if these can be driven out and swap the existing tumbler/key with the new one?

For what it's worth, a new lock cylinder that matches the existing keys has to be ordered from the dealer. In my case (Canada), it had to be ordered and programmed from Germany. No return or refund on that part either.
I didn't bother and just installed remote locking.

190E Door Lock
 

We run into this problem before also where the front shaft breaks. If we are talking about the same part that is broken than we have a part you may be interested in. (photo attached) We had a machine shop make this for us. E-mail us with the subject; 190E Door Lock.

My door locks have not been working correctly. Trunk opens and closes, driver opens and the passgenger closes.

I finnaly got around to takingout one of the cylinders and the little key thing (above phot) is broken. I assume the same issue is at fault on the passenger door.

I sent a message to Mr Maybach but his last post is 2 years old. Anyone know of a different contact for him or any other ways to get this part?

Thanks

What is the price?

Your in luck!
 

We had them machine made back when we used to do a lot of these repairs and only have 2 left. We posted them in e-bay for $25 a piece. check out some of our vintage Mercedes parts. Happy shopping.

Sorry to gravedig this thread, but does anyone still have a source for the lock shaft shown above? This seems to be the only source for this part, since all of the intact salvage parts are the non-alarm version. What's worse, the W124 with an alarm used a different shaft...

Any chance of getting more of these made?

Just take the tumblers out so that any key will open the door. A thief is gonna steal your car whether it's locked or not. Kids will stay out if it's locked (generally) so no one needs to know that your door can be unlocked with a screwdriver,,,

I also need this piece, exactly as pictured by Mr Maybach back in 2004. Looks like I'll be searching junkyards. Or maybe I'll try my luck with a Dremel tool on a scrap of 6061 aluminum. Won't be pretty, but might work.

And a comment to mespe's solution above: There's 10 or 12 wafer tumblers. Usually several will fit whatever key you have. They just need to be rearranged into the appropriate slots. Leave out the ones that don't fit, or file them down until they do. Even just one tumbler will keep a screwdriver from working, though trivial for a lock-pick.
