Why not provide your MB dealer with proof of ownership and VIN and let him cut new keys?

You usually need the key to turn the switch to the #1 position to remove the lockset... Don't know about the electrical plug on back; however.

Hello rwa73, if your car still has the original ignition, and the key fits all your locks, I would go to the dealer. I went to the novi dealer with my title,(regestration is also accepted), and my drivers license, and they had keys ready for pick up within 5 days... I think this is the way to go. I don't know it the electrical connector has a lock. I have a grey market car, and they were still able to get the code...

There are screws (I believe slotted) holding the switch assembly in place.

Removing the cylinder and lock without key is a very big deal so I agree it would be better, if the lock hadn't been changed, to get the correct keys from the dealer.

have you looked at the back of the switch using a mirror to see if there are three screws holding the plug on??

Once you get the pin ground down and are able to slide the steering lock out of the column you will need to slice the three screws off that hold the ignition switch to the steering lock then turn the switch to position 1 to unplug the connector. I assume you intend to replace the steering lock assembly along with the key and tumbler.

Would have saved a little time if you had mentioned this in post #1.

Interesting that all the locks were changed. That must have been expensive.
Can't help but wonder why. Do you have records per chance?

Did you try the glove box?

The 107 chassis and body manual was very informative. One note that said remove plug from assembly. What great help.

The following instructions are for a 560...
There is a lock on the plug on the 560, but do not know about the 380.

"Unplug the wire harness from the rear of the switch. On my original the key had to be in
the 'on' position to release the plug. On the replacement switch this locking tab was not
there"



Then we are back to square one. Need the key. Or the switch can be drilled out as a last resort.

Yep, for the 560 anyways...
I find it interesting that ALL his locks were changed, although he has not responded if the glovebox would lock/unlock.

I can understand the driver door, and trunk, but glovebox and passenger door? I bet that cost a pretty penny. Sure makes you wonder if the key cutter messed up, don't it?
