tumbler lock for ignition

[Doctor Revolver]

Hi there,

I am currently replacing the ignition tumbler in my 240D and wonder if any of you have successfully modified the screw on locking mechanism so that you don't need to unlatch it with the metal pin thingy you fashioned from a paperclip.

I am more paranoid about my key getting stuck, than I am about somebody stealing my car as a result of this modification.

There is a website out there with detailed instructions, but it's not free.
