[R129 SL] Ignition switch/key problem

[Jan Kuylaars]

Chris.
You have a big problem.
Normally should open the doors , activate the central locker for the
boot.
There are two wires and switch to do so. All of other central locking
parts are in the boot.
And if your boot lock not will react is properly the air pipe  or the
membrane damaged .
So the only thing you can do is to drill out the lock cylinder in the
boot and then with a hook release the iron piece from the membrane to
the locker.
Or ask your dealer if they have an other suggestion.

Hi, I hope you sort your key problem. I have a key problem of a
different sort at the momment. My only key for the car (1990 R129) is
locked in the boot. The central locking has failed on the boot and only
locks it. It wont unlock without the key which is in the boot. Any
suggestions which dont involve cutting would be gratefully recieved. I
have obtained another key from Mercedes but it doesn't fit any of the
locks which is supprising as all the locks operate with the same and
only key I have so they all must have been changed at some time.

I had this problem as well - my mechanic explained that it is a common
problem with the early models (mine is a '91 as well) and can prove to
be very expensive if you DON'T get the key out. Once out, it is a fairly
easy fix.  The keys & ignition tumblers tend to wear out and you have to
order a replacement key at the dealer (bring your registration the VIN
number and a driver's license).  Keep trying and jiggling to get the key
out, if you don't get it out, it's VERY expensive to repair!
Just replacing the key may solve the problem too.
 
Just my 2 cents.

My '91 500SL has developed a serious problem.  When I turn off the
ignition and try to remove the key I have trouble turning it to the
extreme counter--clockwise detent so the key can be removed  Moving the
steering wheel while attempting to turn the key does not help, nor does
using other keys (I have 3 keys for this car).  After a lot of playing
around with the key in the lock, I am finally able to remove it.
Likewise it is sometimes difficult to turn the ignition switch clockwise
to start the engine- it is sticky.  A shot of aerosol WD-40 injected
into the lock did not help.  Anyone had this problem and found a fix?
I'm afraid if I need to replace the ignition switch I may also have to
replace all the other locks as well resulting in a major expense.
