You must somehow get the ignition to the "on" position. Remove the cover around the steering column and there should be a hole below the ignition switch/key cylinder. Insert a drill bit (a size that can go into the hole), tap it with a hammer until the key cylinder can slide out. Remember in order to do this, the key must be set to "on". If you are unable to to get it to the "on" position. You must drill the lock pin inside that hole until the key cylinder can be removed.

You really need a locksmith to sort this out.It is tricky to remove the lock unless you know exactly where to drill.

the actuator inside the sterring column that the lock cylinder turns is boken, this is a very complex job and is not for the home tech without a factory service manual.

disconnect the battery and pull the air bag fuse out to diable the air bag. Remove the steering coulmb trim covers and expose the lock cylinder. If the lock cylinder can be turned and is functional then push in the bottom tab and turn the lock cylinder then pull the whole cylinder out. If the keys broke inside and the lock cylinder is not functional the bottom tab will need to be drilled out.

Its usually NOT the lock cylinder on the 470s, its usually the housing. The cylinder is on the dash and points towards the engine. Behind the plastic dash panel (once removed) you will see it in fact sticks in an aluminum tube that goes down 2 or 3 inches, then makes 2 turns, left to attatch to the steering column, and right to attatch to the actual ignition switch. The gear and rod assembly that the cylinder attatches to that allows it to rotate the switch usually shatters in the middle and the key starts freewheeling because there is no longer any attatchment to any of the gears or springs or click points that youd usually feel as the rotational resistance. UNFORTUNATELY this is not a 5 minute job (If it was, cars would be a breeze to steal!). Youll need at least a lock cylinder housing (dealer stock em, they break all the tyme), and IF your cylinder is undamaged, change the housing (it bolts to the steering column and extends from column towards center console area where the ignition SWITCH is actually located). If your cylinder is damaged or the housing is so shredded you cant remove the lock cylinder by normal means...then youll also need the cylinder...and it will have to be recoded to the vehicle so the anti theft will allow the new keys/cylinder to start the car. If your old cylinder and keys are intact, then transfer them to the new housing and car wont even know it happened and should start up and work as normal. Some can be removed intact, some cant...depends on how yours broke.

Below are instructions for changing the lock cylinder as well as a few diagrams. Best of luck.
