Key is broken off half in cly.
Physically removing a piece of an ignition key from the tumbler is practically impossible. The tumbler is filled with spring loaded tabs which raise and lower against EVERY notch on a key. That resistance will fight your every motion as you try to back the key remnant out. As one tab releases, the next in line raises into the vacancy just created. GM, even with the "fob"/ chip installed in most of their keys, also put greater anti-theft detail into their ignition tumblers. IF this is an ignition lock that has a chip sensor, the practical repair is a complete key/tumbler replacement. This isn't a DIY repair. It will involve removing the steering wheel and column covers, air bag, AND re-coding the vehicle computer to accept and recognize the new key/chip code. The re-coding CAN be done at home. Immediately after the new tumbler is installed, leaving the ignition in the "run" position for 1 hour, will re-code the antitheft in the computer.
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.

on the left side of barrel, look for a dowel, there should be a vary small opening that you can take something as small as a pinhead and push the dowel in ,while pushing in on dowel pull the barrel out.the key may need to also be in on position for removal. try that and see if it works. if not please repost your question. thank you for choosing fixya.com
