Re: [MBZ] 79 300SD W116 - the dreaded "key won't turn" situation

[David Bruckmann via Mercedes]

It was indeed the column lock that failed, not the tumbler. 

Tom Hanson confirmed that the tumblers are NLA, although he did say "There 
might be some of these back next year, but I can't be sure yet.", so there's 
hope.

I would have ordered a replacement tumbler out of an abundance of caution, but 
since they're NLA it'll have to be looked at, cleaned and lubed. Fingers 
crossed!

Thanks everyone for the guidance and experience!

Maybe take the tumbler to a locksmith for a professional opinion, they can 
inspect and replace any springs or wafers that are questionable.

Re: [MBZ] 79 300SD W116 - the dreaded "key won't turn" situation

[Curley McLain via Mercedes]

Waytago!   After the cylinter and key were out, did the cylinder turn 
freely?   (Indicating the problem was actually in the steering lock 
itself)   In 40+ years, I've never heard of a steering lock failure.  
They are normally not lubricated.  Tom can confirm(or refute) that.

Victory!

For reference, unlike later models, the W116 doesn't require the key to be in a 
particular position to remove the electrical connector from the ignition lock. 
By loosening the three flathead screws slightly, I was able to determine that 
the electrical portion was NOT the problem.

By some MIRACLE, the key was turning JUST far enough to allow me to depress the 
lock pin that prevents removal of the steering lock from the steering column. 
If that hadn't been true, it would have been a bloodbath because there's really 
no room to work in there. Anyway, I lucked out and then just had to unbolt the 
steering column tube (two bolts) and basically reef down on the steering wheel 
until the lock assembly is withdrawn from the column tube. The normal procedure 
is to remove the protective cap before attempting to remove the column lock, 
but since I couldn't turn the key...

Anyway, chuffed with victory having extricated the column lock, I set to work 
on it in the kitchen! I needed to get that key to position 1 in order to remove 
the hardened steel cover. I attacked the back of the steering lock assembly 
where there's a cover plate pressed into the surface. It took about 15 minutes 
with an oscillating Dremel tool until whatever was in it came free. Hallelujah, 
I was able to turn the key, extract the lock cylinder, and do the happy dance.

I have ordered a new genuine MB column lock from FCP Euro and it will be here 
tomorrow!

Incidentally, the column lock was completely dry, as was the tumbler. I'll 
grease them up with hopefully-appropriate lube before reassembly. Have sent a 
note to Tom Hanson at the Classic Center as well to see if there's really no 
longer any ignition lock tumblers available for this car.

[Curt Raymond via Mercedes]

 I'm not sure a new cylinder is usually required. I don't really see how they 
go "bad". I'd bet many were replaced which were merely cruddy inside. A good 
locksmith should be able to clean/refurbish a lock cylinder. Might have to 
replace some of the springs, I often stretched 'em getting them out.

So, if you cannot buy the correct parts, you have to improvise. 
Disconnect the existing ignition setup but leave it in place so 
everything looks pretty normal but install some form of aftermarket 
ignition switch in an inconspicuous spot and carry on. If it is a 
beater, no worries. If it is immaculate, try not to bodge it to the 
point where it could not later be restored and hope that MB or someone 
in China decides to start making the replacement parts you need.

A fellow I supplied with a bunch of my spare R107 parts for his rebuild of a

Re: [MBZ] 79 300SD W116 - the dreaded "key won't turn" situation

[Max Dillon via Mercedes]

On my '95 cabriolet, I cut apart the lock housing with a Dremel tool, because a 
thief had pretty much destroyed the ignition lock and no way to get the key to 
turn.

Once the dash parts around the steering column were removed, and the steering 
column loosened so it dropped down to grant more access, the body of the lock 
is pretty soft and I could easily cut it up so as to remove the switch.  
Replaced steering column, switch, and tumbler.  Used parts work fine, except 
for the tumbler.

Re: [MBZ] 79 300SD W116 - the dreaded "key won't turn" situation

[Clay Monroe via Mercedes]

The SD had that issue, sort of.  There is the end of the tumbler that fits into 
a sliding switch mechanism once you turn the key.  The SD had somehow buggered 
that up, so that it would not disengage the steering lock and allow the key to 
turn.  I had to get the tumbler out to see if a flat head would allow the thing 
to engage and start the car.  Lots of fiddling with it to get steering lock to 
disengage and for the screw driver to twist to light off.  I had to get a PnP 
part to put the original tumbler in, as there was no issue with the tumbler.

Maybe it's 3 bolts/screws, it's been so long...  And for me, never on a 116.  
But 116 and 107 share

 I don't think your problem can be the lock. The wafers retract or they don't. 
When they retract they either move enough to turn the lock or they don't, 
theres no way for the lock to open partially. I think your lock cylinder is 
working correctly and something beyond it is binding up...

One thing that worries me is that it turns _a little_, like maybe 45 degrees. 
It clearly passes into different territory within the range of the ignition 
switch itself, because there's a point at which the door buzzer begins to 
sound, etc. 

When the key stops turning, it STOPS. No ifs ands or buts. But alas it does not 
reach the ACC position. Is this still the lock cylinder itself, or do I have a

Yes, if it turns out of lock, the problem is not with the cylinder.

It could be the problem we had with our 240D/3.0 once (also on vacation):
the tangs driving the electrical switch had broken and jammed, preventing
further turning.

That was cured by removing the switch from the back of the lock assembly
and installing a new switch (I have pictures of the process with the W123
switch, if you are interested).

Here is a picture of the W123 lock.

normally that is "wiggle the steering wheel to get the bind off the 
steering lock", but David said the steering was unlocked.   I'd guess it 
is still a wafer hung up.

The key turns about halfway to the first detent (position 2),
but not nearly far enough to push in the wire and extricate the
cylinder.

If it turned _out_ of lock, then it's not the typical worn key
and/or worn tumbler problem.  The sander is to get it to turn out
of lock.  I'm not sure what to recommend for "unlocked, but not
turning".  Force?

If it turned _out_ of lock, then it's not the typical worn key
and/or worn tumbler problem.  The sander is to get it to turn out
of lock.  I'm not sure what to recommend for "unlocked, but not
turning".  Force?

Sorry, I gave a rather confusing account. There are 3 positions:

1 - Off and steering lock
2 - Accessories
3 - Run

The key turns about halfway to the first detent (position 2), but not nearly 
far enough to push in the wire and extricate the cylinder.

I don't remember, what position does the key need to be for tumbler removal?  I 
thought it was the first, which means your ok.
