If you have a duplicate made, it could be more hooked then it should be; but then any locksmith should be able to deburr it or compare it with the original. If it is the original that is getting stuck, try moving the steering wheel as you turn the key, because the steering lock may be binding. Remember the key has to be exactly in the right position in order to be able to remove it.
Time to buy a new ignition my friend. the one you have can be fixed but it would be much easier to buy a new one. they arn't that hard to replace either. most cars its just a pop out disconnect pop in. its that easy. also for future problems might they occur go to you local autozone or advanced auto and purchase a haynes repair manual for your car. it is invaluable
if it is one with a chip in the key the best thing to do is go to the dealer and get another one made some of the better lock smiths can do it but the dealer can make one by the vin#. if it is not turning over you can put a push button on it and that will let the starter turn and allow the engine to start.

The vehicles covered by this guide use one of two types of ignition switches:
A mechanical key and lock cylinder built into the steering column, that works a pull rod to actuate the separate electrical portion of the ignition switch mounted further down the steering column. For more information and replacement procedures on this type of switch, please see .
An instrument panel-mounted ignition switch is also used on some W-Body vehicles. To service this switch, the radio, heater & A/C control panel and the instrument cluster must be removed. All of these procedures are found elsewhere in this section.
REMOVAL & INSTALLATION Instrument Panel-Mounted Ignition Switch
You must perform the Body Control Module (BCM) theft deterrent relearn procedure after replacement of the ignition lock cylinder. Failure to perform this relearn procedure means the BCM will not function properly. This means the vehicle will not be theft protected by the Passlock system and the engine may not crank or start. GM recommends that this procedure be performed with their Tech 2® or equivalent scan tool. An alternate relearn procedure is given at the end of this procedure.
Disconnect the negative battery cable.
Remove the radio assembly following the procedures found in this section.
Remove the heater & A/C control head assembly following the procedures found in this section.
Remove the instrument cluster assembly following the procedures found in this section.
Detach the electrical connectors from the ignition switch.
Insert the key and turn the ignition switch lock cylinder to the ACC position.
Depress the transaxle park/lock cable retainer to release, then pull to remove the cable from the ignition switch.
