Manual Lock Problem
I have a 1976 300D 115 and I have restored alot of items on it this winter, I noticed the other day that my drivers door is not able to lock, although all of the other doors lock fine, I do not have electric locks, they are manual. I am wondering once I open this up and take a look are parts available to repair the locks on these or will a locksmith be needed to get parts for it? Thanks much.

Correct me if i'm wrong...
Call your dealership to be sure, but most likely you need to take your VIN number to a dealership if it is the lock/tumbler assembly that needs to be replaced. The parts are available, and you'll most likely get two spare keys with the lock. It wouldn't surprise me if it was actually a problem with the linkage though.

Vacuum locks
Your locks would not be electric, but they may be vacuum activated. There are no lock switches and are activated by the key in the door or just by manually locking a door. You may have vacuum locks and not know. One of my locks would not work and I only had to take off the door panel and free free up the vacuum switch which ws stuck in the up position. Take off your door panel and see what you have, I have seen locking parts on ebay for sale, just search "mercedes 115."

So thanks so far for all of your info maybe I have thought they are manual is because the vacuum has never worked although i do not know if they are manual or electric yet. I want to remove the door panel now but I do not know how to remove a panel on a 115 do any of you know of a good article on how to do this? Thanks again for your expertise.

The door lock is a wafer type and is probably gummed up. If you are the tinkering type, you can pull it and clean it up. There are VERY small springs inside and the wafers MUST go back in the same order or you WILL need a need lock cylinder. Use TriFlow to lube it as most other lubes will gum it up again and/or be too stiff to let the springs do their job.
You may have luck just flushing the removed but still assembled cylinder with carb cleaner and running the key in and out till you free it up. If this sound too daunting, take the whole car or just the cylinder to a locksmith. They will clean and lube for a reasonable price. If the key turns but doesn't lock the door, ignore all the above and instead clean/lube the lock rods and maybe the door latch itself. Also check that the vacuum system isn't fighting you. You should be able to disconnect the rod from the vacuum diaphragm or at least the vacuum lines so you can check everything. Michael
