    You need to remove the cover above and below the steering column ( slide the side chrome strips to release)
    This exposes the steering lock. From memory... ( I can't get at mine at the moment - the gearbox is out getting a birthday, and the car is parked against a wall.) the two securing bolts underneath are the conical head type and need to be loosened with a small chisel on the side.

    Cant recall any more... should get you started at least!

    If the tumblers are jamming, I'd suggest trying some graphite powder down the barrel. It worked wonders on my DS23.
    Cheers,

    I removed mine by drilling a hole at the 12 o'clock position through the aluminium casting to enable the shaft of a thin screwdriver to be pushed through it to push back the locking finger so that the ignition switch can be withdrawn. I can take a look later to define exactly where you need to drill.

    Once the switch is out it was relatively easy to take it apart, two C clips, but watch the position of the bits inside as you take it apart slowly. Mine was really grimy but it cleaned up ok. Its all copper inside apart from one solder track which may be a bit worn and need some fresh solder adding to build up its profile.

    I did all that put it back together and still got intermittent starting issues! Hence the suggestion of fitting a pushbutton starter switch. I fitted mine in the hole where the cigarette lighter goes, it's just a case of running two wires from it to two of the wires feeding the ignition switch that sit on top of the bundle. Then the button operates the solenoid and the key just operates the ignition. Solved the problem in my case.

    Cheers
