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...
