turn the ignition to the on position then on the bottom of the steering colum just under the lock cylender thare is a hole that leads up to the cylender. get a straight pick or somthing with a point on it and insert in hole apply a little steady force while pulling straight out on the cylender. i am assuming you are talking about the ignition lock cylender.

Hi there
I had something similar on my merc
but yours sounds similar.
the fact that you say the steering lock no longer works is very worrying, most times the key not going past position 1 is due to the steering lock being actuated and the pressure in it has to be released before the key will turn, you will have to go from lock to lock the find where the steering lock actuates when this happens follow my wiggle method of turning the steering wheel slightly when the steering lock is on the disengage it. ie keep trying the key whilst wiggeling the steering wheel.
hope that helps

SOURCE: Want to remove the ignition lock cylinder since a broken key is stuck inside.

get a phillipshead un do about 4 screws from underneath plastic cover which hides steering colume. remove cover you will see white plug on the left hand side of ignition barrel disconect.then right hand side there will be acable disconect.now get a small chissel and anti clockwise tap bolts which have no heads on them that are on top of steering colume when they are alittle bit lose use plyers its easier pull bolts out clamp will then come of and then you can pull whole ignition of. now there is 2 brass pins which hold barrel in ignition up near the key end remove and barrel will come out but it might be easier to take whole ignition to locksmith and get them to do it and get new key for around 30 bucks i did a mates about couple months ago seeya orangepeel.
