Help! My 90 500sl's Only Key Broke In Ignition!
 

I Have One Key In My 90 500sl.....and I Broke It In The Ignition.ORIGINALY THE KEY WOULD NOT TURN TO OFF POSITION. WOULD HAVE TO JIGGLE TO GET TO O POSITION. Would Like To Try To Fix Myself. It's In My Garage! I Can't Get 1/2 Of Key Out. Do I Have To Drill Out? In Order To Get Lock Cylinder Apart? I Know I Will Have To Order A New Key And Cylinder From Mercedes To Have It Keyed Correct. Can't Seem To Get Lock Cylinder Apart. Any Help???? Thanks!
