I lost the keys to my car and need to replace the lock cylinder because it is cheaper than a locksmith so what do I need to do.
Do you
have the same problem?

REMOVAL:
Disconnect the negative battery cable.
Remove the steering wheel (explained below)
Using suitable locking pliers, twist the ignition switch cap or bezel until it separates from the lock cylinder.
Using a 3 / 8 in. Drill bit, drill down the middle of the key slot approximately 1 3 / 4 in. (44mm) until the lock cylinder breaks loose from the breakaway base of the lock cylinder. Remove the lock cylinder and drill shavings from the steering column tube flange.
Remove the steering column upper bearing retainer, steering column lock housing and bearing, ignition switch lock cylinder and steering column lock gear. Thoroughly clean all drill shavings and other foreign materials from the casting.
Carefully inspect the steering column tube flange for damage. If there is damage, the steering column tube flange must be replaced.

INSTALLATION:
If necessary, replace the steering column tube flange.
Install the steering column lock gear and ignition switch lock cylinder.
Install the trim and electrical parts.
Install a new ignition switch lock cylinder as outlined earlier in this section.
Install the steering wheel.
Connect the negative battery cable, then check the lock cylinder for proper operation.

STEERING WHEEL REMOVAL:
Center the front wheels in the straight ahead position.
Disconnect the negative, then the positive battery cables. Wait one minute for the air bag diagnostic monitor to deplete its stored energy.
Remove the two back cover side plugs, then remove the two air bag module retaining screws.
Disconnect the air bag wire harness from the driver's side air bag module, then remove the driver's side air bag module from the steering wheel.
Disconnect the speed control wiring harness from the steering wheel, if equipped.
Remove and discard the steering wheel retaining bolt.
Install Steering Wheel Puller T67L-3600-A and remove the steering wheel. Route the air bag sliding contact assembly wire harness through the steering wheel as the wheel is lifted off the steering gear input worm gear and rack.

STEERING WHEEL INSTALLATION:
Make sure the vehicle's front wheels are still in the straight ahead position.

WARNING
Make sure the wiring does not get trapped between the steering wheel and air bag sliding contact, as damage to the sliding contact wiring may occur.

Route the air bag sliding contact wire harness through the steering wheel opening at the three o'clock position and position the steering wheel on the steering gear input worm gear and rack. The steering wheel and steering gear input worm gear and rack alignment marks should be aligned. Be sure the air bag sliding contact wire is not pinched.
Install a new steering wheel retaining bolt, then tighten to 23-33 ft. Lbs. (31-48 Nm).
Attach the speed control wire harness to the steering wheel, then snap the connector assembly into the steering wheel clip.
Connect the air bag wire harness to the driver side air bag module, then position the module to the steering wheel. Tighten the air bag module retaining screws to 8-10 ft. Lbs. (10-14 Nm).
Connect the positive, then the negative battery cables. Verify the air bag warning indicator.
