To replace the ignition switch one has to remove upper and lower steering column covers, lock the steering column in the 'full-down' position, insert the key into the Legendary Lock and position it in the Run position. Pull back the small safety tab on the ignition switch and release the connectors, disconnect the larger connector by unscrewing the bolt that holds the switch in place and pulling the switch out of the steering column. For the lock cylinder, same as with the ignition, the upper and lower steering column covers have to be removed, the steering column has to be locked and key has to inserted in the Run position. If required, there will be a fastener to the skreem/wcm where the tabs can be removed and the skreem/wcm slid backwards slightly to reveal the lock cylinder release tab. With a small flat head screwdriver pull the lock cylinder release tab up and remove the key and the lock cylinder as a single unit. For installation, the key should be inserted into the lock and rotated backwards to the run position, it is also important to line up of the slots of the lock cylinder to the housing before it is inserted and clips into place. Switch off the key and try to rotate it and ensure that the key and the cylinder work correctly. The SKREEM/WCM which translates to Sentry Key Remote Entry Module or Wireless Control Module is very essential in the alarm system it has receivers for entry without use of keys and for tire pressure. It has a circular antenna through which it establishes contact with a microprocessor chip in the factory programmed key used in the ignition of the vehicle. The new SKREEM/WCM module shall be programmed by using a diagnostic scan tool before driving the vehicle and it is recommended that two keys at least should be programmed. To remove the SKREEM/WCM: Disconnect and set aside the wiper switch, unscrew the lock cylinder housing, pry the retaining arms of it back and slide the SKREEM/WCM module off. Installation instructions are the opposite of removal ones.
