83 240D ignition key lost

I just bought a fine '83 240D - 4 spd std - but minus all keys. The ignition
switch has been replaced and it does not match the door keys - and no key
code can be found. The door key has now been made by a lock smith but no
ignition key. They have just finished making an ignition key for someone
else by drilling out the plug - tumbler unit without destroying any of the
other parts in the switch, i.e. the steering lock and remainder of the
parts. they have done this quite a few times and are confident they can do
it again for time - $65 an hour about 4 -5 - hrs. then parts and assembly;
tumbler plug at least maybe more. The part was provided by the customer
which cost $110 - not clear if it was just the plug or the whole switch - my
guess at the moment is it was in fact the whole switch.

Two other local mechanic shops tell me this is unlikely and they will do it
but will replace the entire switch and it will be about $400 or more plus
parts. I can get a used switch $100 or a new one  $ unknown at the moment. I
also have a very reputable local  MB shop [Larry Daniels - Cincinnati, Ohio]
that says it can get the original out without drilling and make a key for
$250 total no parts required. This is fine since the switch is new anyway

My fear is he will discover he can not do it for that after starting and it
will also be more like $600 +.  Does he know something the others do not
know or have a magic special factory tool that lets him turn the switch and
release-remove the tumbler - which can only be done only if you have a key
that turns the switch to accessory and releases all the various locking pins
so the tumbler unit can be removed and a key made by a lock smith. If so it
is worth the $250 price - plus towing.

Any experience with keyless cars being re-keyed? Removal of the entire unit
or just the tumbler section ?

I have messed around with the ignition lock. First of all... there is no way
to remove the lock with the key in locked position...The pin will not allow
it to slide out. Unless, you totally removed the steering panels so you have
clear access to the pin and drill it out... which is most likely to be hard
metal too.

Ignition tumbler is easily obtained from dealer wtih VIN and proof of
ownership... for $35 with a new key... additional keys at $15 I think. Whole
lock and tumbler is like $160 or so.

You can drill out the tumbler... just need hardened drill bit. (I haven't
tried this yet). Dealer does the same work and charge the same amount of
money as you mentioned so let the dealer do it right for you.

As far as the third guy? No way in the world.

Thanks Tiger. The more I look the more consistent the information is with
yours.

In case you did not see my other post - query:

I have heard in this group that the 300 turbo can be installed in the 240
[W123] but only with
the 300 auto transmission - that is, not the 240 auto transmission.  Can the
240D  manual transmission be applied to the 300 turbo engine?  specifically
a 1983 240 D std 4 spd transmission ?
Wish there was an overdrive transmission available ! in the US.  std or
auto.

I really don't know about the tranny... I will assume it might fit... In
Europe, that was an option. You have to try it to find out.

I am a locksmith, and it should be no problem to fit a key for that car with
out drilling the lock.  If the locksmith you had could not do it, ask him if
he knows a competent one.

I did't see the earlier parts of this thread, but I went through four
lockesmiths locally with the same problem, and never did find one that could
make a key for the ignition of my '75 240D. Fortunately, I had the presence
of mind, or maybe somebody here suggested it, to call the dealer, who
supplied a new key for my particular VIN for around $29.00.

How would you do it without a code for the key for a new ignition - i.e.
does not match the car vin ?

I am curious, so is the lock smith and 2 mercedes shops [including the one
that installed the new ignition switch in 1998 and no longer has the code
records] and the local dealer.  The lock smith could try to do an impression
but was at the same time drilling another 240D because the impression
technique failed and took just as long if it did work.
thanks,  Pete

A key can be fit by impression to your car.  Sometimes this is tricky, but
usually it can be done with the right technique.  It should take the
locksmith a half an hour or so to make this key.

Should be $100 to $150.  Drilling out the lock cylinder is the last possible
option I would pursue.  If you have not yet scrapped the lock, try another
locksmith.

Getting keys for the doors is no problem. The VIN # and proof of ownership
at your local MB dealer will take care of that....if they are original
equipment.
As far as the ignition lock is concerned competent locksmiths can cut you a
key that should work. However, MB keys are steel and not brass like most
other manufacturers so you could face a problem should you ever break a
brass key in the lock.
There is new technology that allows locksmiths with the proper tools to
determine just where the tumblers should be in order to turn the ignition.
Check around until you find one that can do the job. If he wants $100 to do
the job tear a $100 bill in half and hand him one half. Tell him he gets the
other half when you see the key turn and the car start. Separates the men
from the boys at that point.

Why is having a steel key broken in a lock preferable to having a brass key
broken in the lock?

Steel keys have only one advantage over brass keys.  They do not ear as fast
as brass keys do.  The down side is they wear out the lock faster.  A
duplicate key for an 83 240D is about $3 to $5 at the local locksmith.  It
should last at least 2 to 3 years if you retire it at the first sign of
wear.  If you were to use it until failure it would be over 10 years.

I would hardly call the technology new.  I learned the way to do it long
before the OP's car was built.

Unless I thought I was dealing with a complete flake, I always presented the
bill after the service was rendered.  If someone were to pull that stunt on
me, I would be tempted to tear the half of the bill in little pieces and
return it to the clown with the suggestion of what he could do with the
little pieces.

Have you ever heard of a steel key breaking off in a lock? Also, no
locksmith I've ever talked to will cut a steel key because their machines
are typically not capable of doing so. Tears 'em up. A little graphite
sprayed into locks once a year or so keeps things working real nice.....as a
rule.....which always has exceptions.

I still have the original keys for both my '81 240D and '81 300D (non-turbo)
and they all work great. Of course the 240 just turned 125k but the 300 has
nearly 300k. These are the most bullet-proof vehicles I've ever owned.

Yes I have.  I have removed lots of them.  Steel keys fail also, and they
tend ro give a lot less warning than do the brass ones.  Except for most
Porsche's I think all of the German, Swedish, French and Itialian cars have
had steel keys from the factory as they have their locks made by the same
companies.

I have cut steel keys when folks have demanded it.  Cutting steel just
requires a slower speed on the cutter and a little slower feed rate than the
brass keys.  Unfortunately most key machines are not equipped to change the
speed of the cutters so this is why they will smoke the cutters cutting
steel keys.

Also if you go puffing graphite into a lock on a european car that is
lubricated with thick grease you might induce a failure as when you mix
graphite with sticky grease you can clog up the works.

I like the lubrication graphite provides, my 300D has graphite lubricated
locks, but I have stripped them down and cleaned out all of the sticky crud.
The trunk lock excepted, that still has the sticky crud inside and no
graphite.

I have been a locksmith since Jimmy Carter was president and have always
worked on European cars, so I have seen lots of the insides of locks.  Brass
keys are better.

I still use the original brass keys for my 1968 Buicks...  Although
they are a bit worn they still work fine...
