Hi everyone.. I have a 1991 300CE Benz with broken key in the ignition. I have called locksmiths and they are unable to retrieve or removed the broken key. I have a spare which I can use to use the car once I get the busted key out.. Is there a tutorial or does anyone know how I can go about disassembling the ignition? Are there any suggestions or tricks I should be aware of before I start disassemble? Thank you all for any helpful ideas or experiance you can share.
