This happens to me sometimes because the pressure of the steering lock is enough to keep me from being able to turn the key. Try moving the steering wheel while turning the key, if that doesn't work, flip the key over and try again (unless it is a one sided key), if that doesn't work, then you are likely looking at a bad lock cylinder and it will have to be replaced.

If turning the steering wheel to the left or right doesn't allow the key to turn, it sounds like your tumblers in the lock cylinder have failed. Unfortunately, there is no way to know when this is going to happen, but eventually, it happens. Not a real expensive fix. Replace the ignition/lock cylinder.

If you're having trouble starting your car and you've been through troubleshooting the starter and alternator, it may be time to replace the ignition switch. Though this is a job best suited for a professional mechanic, if you're willing to take it on, here's how to replace the ignition switch in your car.
Instructions:
1.Disconnect the negative battery cable from the terminal on the battery. Remove the upper and lower steering column covers by unscrewing or unclipping them.
2.Remove the steering wheel by lifting off the center cover, disconnecting the horn wire and removing the retaining nut and washer. Make a mark on the steering wheel spline and the wheel itself so you can line it back up precisely. Pull the steering wheel straight back to remove from the shaft.
3.Take off windshield wiper and turn signal switches by pulling them off as you did the steering wheel and disconnect the wiring. Slide the spacer sleeve off of the steering column.
4. Unscrew the ignition switch mounting screws. Pull out the ignition switch. Disconnect the wiring connector from back of the ignition switch. Simply loosen the tabs and pull it out.
5. Insert your key into the ignition. Turn the ignition switch to the locked position. Depress the retaining pin with a small screwdriver and turn the key to the Off position to free the cylinder. Once it is free, turn the key to lock position and remove the key and key cylinder.
6. Install your old key cylinder into the new ignition switch assembly. Make sure the contacts in the cylinder and assembly line up. Reattach wiring to ignition switch, slide it into place, screw in mounting screws and reassemble steering wheel and switches.

I hope this helps....these are the steps to removing and replacing the cylinder:

1. Remove the knee bolster.
   
2. Remove the steering column trim covers from the steering column.
   
3. Disconnect the steering column electrical connectors.
   
4. Remove the wire harness assembly from the steering column and the wire harness strap.
   
5. Slide the 2 connectors of the turn signal and multifunction switch assembly out of the bulkhead connector.
   
6. Remove the key alarm connector from the lock module assembly in the following way:
   
7. Rotate the key alarm connector 90 degrees.
   
8. Pull the key alarm connector out of the lock module assembly.
   
9. Remove the passkey connector from the lock module assembly.
   
10. Remove the connector from the electric park lock, for vehicles equipped with floor shifters.
    
11. Remove the ignition switch from the lock module using tool J42759 or equivalent.
    

To install:

1. Install the ignition switch to the lock module
   
2. Install the key alarm connector into the lock module assembly.
   
3. Push the key alarm connector into the lock module assembly.
   
4. Rotate the key alarm connector 90 degrees so that the key alarm connector locks into place.
   
5. Install the passkey connector into the lock module assembly.
   
6. Install the connector to the electric park lock, for vehicles equipped with floor shifters.
   
7. Slide the 2 connectors of the turn signal and multifunction switch into the bulkhead connector.
   
8. Attach the wire harness assembly to the steering column wire harness strap.
   
9. Connect the steering column electrical connectors to the vehicle.
   
10. Install the trim covers to the column.
    
11. Install the knee bolster.
    
12. Enable the SIR system.
    
13. It may be necessary to reprogram the theft deterrent system if the module was replaced.

Please rate and god bless.

there should be a wire linkage between the door lock and the button that could be the missing/broken piece ??
