Bought all new locks for my 300CD, finally I can lock both doors, ignition and the trunk and will be able to lock the glove-box with one key.

I don't think I will have a problem with the doors, trunk and glove-box but the ignition I'm a little worried about. Do I have to disassemble the entire ignition system, where do I start?

Was looking for manuals online, but they seem to be all non accessible at the moment.
