How to replace the ignition lock cylinder on Cadillac CTS?

The battery negative cable requires removal to replace the ignition switch lock cylinder. Begin by removing the steering column shroud while implementing the correct procedure for models with and without a key release lever knob. Use an allen wrench or similar pick-type tool through the lock housing access hole to gently depress the retainer which allows extraction of the Ignition Lock Cylinder from the lock housing when the key is placed in the run position. The new Ignition Lock Cylinder installation requires positioning it at the run position before putting it into the lock housing while performing rotation checks for proper operation. Complete the installation by placing back the steering column shroud while reconnecting the battery negative cable.

In Cadillac CTS the main use of the Ignition Lock Cylinder is to provide a method that can be used to start the engine with the use of a key that has to be inserted and rotated. This component is contained in the 'Ignition Switch', the device that controls the flow of battery current to the required circuits once the proper key is inserted. In Cadillac CTS particularly, the early models were those that used what one could term as old-fashioned keys to open the ignition as opposed to the modern touchless variants that serve the same purpose. The Cadillac CTS prior models has the steering column mounted ignition lock cylinder, however the later models have made shift to the keyless fobs that signal the car's computer and employ push-button start. Thus, even relative to the modern level, such problems as, for example, increased wear on the keys and tumblers can cause certain problems in operation, and all this requires the constant use of the Ignition Lock Cylinder for such vehicles as ships, planes, etc.
