As I understand this is what we want to use to re lubricate our locks

Is anyone using graphite powder or something similar? The my locks on the door handles love to freeze and I have to melt them with a torch. Not a good long term solution.

Going to call Monday and see if the dealers carry this on the shelf.

I’ve used graphite powder with good results. I’ve heard that some people swear by WD40, and others say to avoid it like the plague. I would not use it as there are better options out there.

I was talking to a MB parts guy last week and he said that his cylinder started to stick and he used the grease you mentioned from MB and he has yet to have it stick since, and that was a couple years ago. I’ll be using this in my rebuilt ignition cylinder.

Those wafers/tumblers look identical to the ones in VW and Porsche locks.

Volkswagen and Porsche used the same manufacturer for their locks as MB (HUF).

I found this on Ebay, looks like these could be used for those with the older style keys  : https://www.ebay.com/itm//251406644634

I also saw VW wafers on the same site when I was looking for the ones I purchased. Those are more likely to work for the non-sidewinder keys as the ones I bought have notches inside the holes.

I think I'm done fooling with keys for a while. I was able to procure 2 extra non-sidewinder/not skinny key cylinders not including the one in the car. I also bought a JMA key blank and took them to "Bee's Keys" in Dallas. They were able to use the individual wafers from the 2 tumblers and and made one and cut a key to fit.  It's a little jagged, but I'm sure it will smooth out since I drive her everyday. I also made sure to buy Mercedes-Benz lock cylinder grease. It comes in a can with a convenient nozzle for shooting it into cylinders as well as 2 other tips.

I'm still looking for a sidewinder cylinder so I can have one key for the car as I do have the wafers for that type of tumbler, but I'll live with 2 for now as long as they look original. If someone can sell me one from a 380SL, those will work too!
