you need to go into the steering wheel, if you are not familar with car then I wouldn't recomend you do it because there are air bag and other electrical inside of that steering. you will end up paying some one more to get it fix if you mess it up
Check out http://99intrigue.shutterfly.com/ignitionswitch. You don't have to remove all of the dash, just the radio and instrument cluster. It's not a big deal - hardest part is getting off the park lock cable, but if you remove the dash center vents, it's a cakewalk.
These cars have an anti theft feature. When parts dont match up or begin to fail, the SECURITY system disables the starter. Read this link, it tells about the problem with GM car anti theft,

The ignition switch on Mercury Sable is integrated into the ignition cylinder. When this switch fails, you may need to purchase a special switch from a Ford dealership if the switch used a wireless transponder.
Instructions for NON Functional Cylinder (Cylinder will Not Turn or No Keys ): 1. Disconnect the negative battery cable. 2. Remove the steering wheel. 3. Using locking pliers, twist the cylinder cap until it separates from the lock cylinder. 4. Using a 3/8 in. (10mm) diameter drill bit, drill down the middle of the ignition lock key slot approximately 13/4 in. (44mm) until the lock cylinder releases from its breakaway base. Remove the lock cylinder and drill shavings from the lock cylinder housing. 5. Remove the retainer, washer, ignition switch and actuator. Thoroughly clean all drill shavings and other foreign materials from the casting. 6. Inspect the lock cylinder housing for damage from the removal operation. If the housing is damaged, it must be replaced.
To install: 1. Replace the lock cylinder housing, if damaged. 2. Install the actuator and ignition switch. 3. Install the trim and electrical parts. 4. Install the ignition lock cylinder. 5. Install the steering wheel. 6. Connect the negative battery cable, then check the lock cylinder operation.
Instructions for Functional Cylinder ( Cylinder will Turn with Key): 1. Disconnect the negative battery cable. 2. Turn the lock cylinder key to the RUN position. 3. Using a 1/8 in. (3mm) diameter wire pin or a small drift, depress the lock cylinder retaining pin through the access hole in the upper steering column shroud (under the ignition lock cylinder) while pulling out on the lock cylinder. Remove the lock cylinder from the column.
To install: 1. Install the lock cylinder by turning it to the RUN position and depressing the retaining pin. Insert the lock cylinder into its housing. Make sure the cylinder is fully seated and aligned in the interlocking washer before turning the key to the OFF position. This will permit the cylinder retaining pin to extend into the cylinder housing. 2. Rotate the lock cylinder using the lock cylinder key, to ensure correct mechanical operation in all positions. 3. Connect the negative battery cable.
Door Lock: When a lock cylinder must be replaced, replace both sides as a set to avoid carrying an extra set of keys. 1. Remove the door trim panel and watershield. 2. Remove the clip attaching the lock cylinder rod to the lock cylinder. 3. Pry the lock cylinder out of the slot in the door.
To install: 1. Work the lock cylinder assembly into the outer door panel. 2. Install the cylinder retainer into the slot and push the retainer onto the lock cylinder. 3. Connect the lock cylinder rod to the lock cylinder and install the clip. Lock and unlock the door to check for proper operation. 4. Install the watershield and door trim panel
Ignition Switch - REMOVAL & INSTALLATION (see Figure 1)
Disconnect the negative battery cable.
Remove the lower column trim panel, then remove the steering
column-to-instrument panel fasteners and carefully lower the column for
access to the switch.
Place the ignition switch in the
OFF-LOCK
position.
If the lock cylinder was removed on vehicles through 1991, the
actuating rod should be pulled up until it stops, then moved down one
detent; the switch is now in the Lock position.
Fig. 1: Adjusting the ignition switch
Remove the ignition switch-to-steering column retainers, then remove the assembly.
To install:
Before installing the ignition switch, place it in the
OFF-LOCK
position, then make sure that the lock cylinder and
actuating rod are in the Locked position (1st detent from the top or 1st
detent to the right of far left detent travel).
Most replacement switches are pinned in the OFF-LOCK position for
installation purposes. If so, the pin MUST be removed after installation
or damage may occur.
Install the activating rod into the ignition switch and assemble
the switch onto the steering column. Once the switch is properly
positioned, tighten the ignition switch-to-steering column retainers to
35 inch lbs. (4.0 Nm).
When installing the ignition switch, use only the specified screws
since over length screws could impair the collapsibility of the column.
Raise the column into position and secure, then install any necessary trim plates.
Make sure the ignition is
OFF
, then connect the negative battery cable.

For 1992-93 vehicles, remove the buzzer switch assembly.
Fig. 1: Ignition cylinder replacement
Carefully remove the lock cylinder screw and the lock cylinder. If
possible, use a magnetic tipped screwdriver on the screw in order to
help prevent the possibility of dropping it.
CAUTION
If the screw is dropped upon removal, it could fall into the
steering column, requiring complete disassembly in order to retrieve the
screw and prevent damage. To install:
Align and install the lock cylinder set. On vehicles through 1991
it will be necessary to rotate the switch clockwise to align the
cylinder key with the keyway in the housing.
Push the lock cylinder all the way in, then carefully install the
retaining screw. Tighten the screw to 22 inch lbs. (2.5 Nm) on tilt
columns or to 40 inch lbs. (4.5 Nm) on standard non-tilt columns.
If necessary, install the buzzer switch assembly.
Reposition and secure the turn signal switch assembly
Align and install the steering wheel.
Make sure the ignition is
OFF
, then connect the negative battery cable.
When carrying a live inflator module, make sure that the bag and trim cover are pointed away from you. Never carry the inflator module by the wires or connector on the underside of the module. In case of accidental deployment, the bag will then deploy with minimal chance of injury.
When placing a live inflator module on a bench or other surface, always face the bag and trim cover up, away from the surface.

I have 07 Pontiac Grand Prix, the wrong key was inserted into the ignition the other day. Now when I try to use the correct key it will not insert completly in the ignition, goes in until last 1/4in of key. Im stuck, I bought the new lock cylinder but how do I get the old one out? I cant get the key to insert all the way so I cant get it to the "On" position, it will not turn at all. The key that was inserted in error is whole and nothing is missing it seems like there is something stuck. Any help would be appreciated...
