Ignition Switch & Lock Cylinder

Print

The vehicles covered by this manual use one of two types of ignition switches:



A mechanical key and lock cylinder built into the steering column, that works a pull rod to actuate the separate electrical portion of the ignition switch mounted further down the steering column. For more information and replacement procedures on this type of switch, please see Section 8.
 
An instrument panel-mounted ignition switch is also used on some W-Body vehicles. To service this switch, the radio, heater & A/C control panel and the instrument cluster must be removed. All of these procedures are found elsewhere in this section.
 

Removal & Installation



Instrument Panel-Mounted Ignition Switch

You must perform the Body Control Module (BCM) theft deterrent relearn procedure after replacement of the ignition lock cylinder. Failure to perform this relearn procedure means the BCM will not function properly. This means the vehicle will not be theft protected by the Passlock system and the engine may not crank or start. GM recommends that this procedure be performed with their Tech 2® or equivalent scan tool. An alternate relearn procedure is given at the end of this procedure.

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the radio assembly following the procedures found in this section.
