Here are the steps for the lock cylinder replacement.

Disengage the two yellow 2-way SIR connectors.
Remove the tilt lever, if equipped.
Remove the upper and lower steering column trim covers.
Insert the key in the lock and turn it to the ON position.
Remove the lock cylinder by pushing against the locking button on the back of the bearing/housing assembly, and pulling outward.
Install he new lock cylinder into the housing. Gently push the lock cylinder into place while rotating counterclockwise.
Install the upper and lower column covers.
Install the tilt lever, if equipped.

Install the left side insulator panel.
Install the AIR BAG fuse.
Connect the negative battery cable.
The ignition switch is the electrical portion of the ignition system that activates the entire ignition system when it is turned ON. It is turned on by the lock cylinder turning and actuator turning the switch. The lock cylinder is the mechanical portion where key is inserted that activates the switch on and off. This is the portion that would cause the key to turn back to OFF after you turn it on. Hope this helps..
