Thanks for that reply xp190

Paper clip etc
 

I got my tumbler out with a straightened paper clip. Stuck the paper clip in the hole and then that hardened steel tumbler cover would turn.

By the way, I used a cheap hand sander to get the stuck key to turn; I popped out the instrument cluster so I could get the hand sander behind the steering wheel and resting on the lock assbly.

This was on a 1984 300D 123 Euro model

Ask any locksmith - NEVER put WD40 or similar lubricant into ANY type of lock - they may seem to work, for a while, but these are sticky substances that actually attract dirt. The only lubricant for a lock is graphite.

190e key wont turn ignition after....
 

After spreading a fine film of graphite on each of my ignition keys just as a "precaution," my dumbass brother/wrench has caused the ignition switch not to turn.

Would something as ridiculous as graphite cause one of the tumblers to stick? Or is this something related to a steering wheel lock gone bad???

Anybody ever have this problem before?

Car is an '89 190e 2.6

Need help.

Graphite probably was not cause - when they go-----they go

If your lock set up is the same as mine (and make sure it is) then you'll want to see this:

major problem with my 1980 123 (240D) a few years ago
but I lucked out when the key turned
after leaving the car set for several days

when my 84 126 (300SD) had the same problem
I sat there sweating on a jot afternoon trying to turn the key
memories of the same miserable heat when I was stuck in the 123

then it came to me that the problem might be temperature related
makes sense
the tumblers are worn out
perhaps a change of temp made just enough difference
between go and no go
so the next morning I when it was cool I went to the car,
got in, turned the key and drove home

as to the WD40 controversy
WD40 should never be used around lock on on boats
it removes lubricants and then evporates
but the goal here is to make the lock work once then replace it
so I don't see it as an issue

door lock cylinder?
 

im gunna jump on this thread with a question.


my driver door lock cylinder recently froze up on me and wont turn at all anymore. is there a procedure to replace that myself?

I am going to raise some ire here
I took my 81 TD into a locksmith with the same problem
he sprayed some WD40 into the keyway
they went around the car and sprayed the rest of the locks

That was two or three years ago
I have not had a problem since
