My ignition lock cylinder froze up on my '84 300D in early 2020. I did some vandalism to get it and the ignition switch (by necessity) out, this from under the dash.

The new one I installed was the Genuine M-B item, this one here:

Not giving Pelican grief in any way, that's where I bought it, you'd think it was the gold standard route.

For the last couple of months the internal spring is so stiff my thumb has a more or less chronic painful spot. Not horrible but annoying as hell. One should not have to put that much muscle into turning the key. The parts of my thumb and forefinger that do the work are getting numb, not exagerating.

From the link, it says the part no longer available. Crap. I recall Kent talking about those probably going on the NA list. Not that a new one would automatically be better but maybe.

Anybody else have this problem?
