• Q: How to remove the Ignition Lock Cylinder on 2002 Cadillac Seville?

  A: The procedure to remove Ignition Lock Cylinder begins by disabling sir and activating the parking brake followed by disconnecting the negative Battery Cable then radio removal. Place the ignition key inside the ignition cylinder. When keys are broken or ignition lock cylinders are seized the technician should remove the knee bolster by first removing the Ignition Lock Cylinder bezel then disconnecting electrical connectors from the switch before unfastening the Ignition Switch from its instrument panel retainer. Use the radio space to pull out the Ignition Switch while you protect your workspace with clean shop towels or a fender cover. The Ignition Lock Cylinder release button is on the plastic Ignition Switch housing so punch the housing at a spot 3/8 inch from the key end with a center point. Drill a small hole using a 1/8 inch drill bit. Use a 1/4 inch drill bit to enlarge the pilot hole which breaks the release button retaining spring at the location while utilizing a magnet to extract the lock cylinder release button. Grasp the Ignition Lock Cylinder while removing it from the switch housing and blow away any plastic flash generated by drilling by using compressed air. Turn the ignition to run mode then find the right lower side Ignition Switch assembly button. Use a small flat-bladed tool to depress and maintain contact with the button while pulling on the ignition cylinder for extraction. The technician must first release the tabs retaining the Ignition Lock Cylinder bezel then remove this bezel to get access to the lock cylinder for installation of the reader/exciter component. Connect the ignition cylinder light pipe to the ignition cylinder while applying the ignition cylinder bezel onto the Ignition Lock Cylinder. The Ignition Lock Cylinder needs to be cleaned if it showed signs of being seized then move to the next steps which include inserting the Ignition Switch into the instrument panel followed by connecting electrical connectors and knee bolster installation. Insert the new Ignition Lock Cylinder into its position on the Ignition Switch while keeping it in run mode and press the button straight into the drilled hole before it fully settles into position. With the ignition key installed in the Ignition Lock Cylinder and the Ignition Lock Cylinder in run, insert it into the instrument panel opening; an audible click will sound from the lock cylinder release button during complete engagement. Use gentle force to check that the lock cylinder is connected before setting the ignition to lock and taking out the key. Reinstall the radio after the negative Battery Cable reconnection and parking brake reset while testing the ignition cylinder and switch function through their entire movement range and enabling sir.
