1991 200 Quattro Ignition switch replacement problem
 

my ignition switch broke. And it burnt out the wire going to my starter.I replaced the starter and the switch

Import Direct Ignition - Ignition Switch Part # 18-0550

Once I plugged it in, I turned the ignition switch with a flathead screwdriver before inserting it into the back of the lock cylinder. The car started. But, no matter how many times I insert it into the locking cylinder, I cant get the key to turn on the car. I saw a mechanism in the back of the cylinder that obviously syncs up with the switch and locks into some grooves.However, no matter how many times I try and slide it in place, it never works.

Heres a few pics of the switch and the back of the locking cylinder. Its extremely hard to take pics of the locking cylinder, since its so deep in the dash.

Does anyone know how to install the switch properly, so I can turn my car on again?

I attached the pics I linked to above.I couldnt find out how to edit my post

Looks like the tang at the end of the lock cylinder is broken time for new a lock cylinder.

@yodasfro

Yes youre right,I think the lock cylinder is broken.Do you know where I can find a guide to replace it?All the guides Ive found are years old and the picture links are dead.

Easiest thing to do would be to replace the whole housing with a good used one.
It's held to the column with one anti-tamper torx bolt. If you need one I have a few good used ones.

I appreciate the offer
 

Thanks but this is easier.

[V8] Ignition Lock Assy R&R?

If by easier you mean the same exact thing then sure.

Replacing the lock assembly tumbler is easier than replacing the lock housing.They are two different parts
