Key Programming Switch State Control





NOTE: The spare key programming switch is a programmable switch which provides the capability to enable/disable the normal customer spare key programming procedure detailed in the Owner's Literature. It must read ENABLE if more than 2 keys need to be programmed into the Instrument Cluster (IC). For additional information, refer to Key Programming Using Two Programmed Keys Using Two Programmed Keys. This programmable switch is provided as a convenience for rental company fleets or other fleet purchasers who may not want the spare key programming procedure available to the vehicle driver.

NOTE: The spare key programming switch state can be viewed with the IC SPAREKEY PID.

NOTE: If the SPAREKEY PID reads ENABLE, up to 8 keys total can be programmed into the IC using Key Programming Using Two Programmed Keys. If the SPAREKEY PID reads DISABLE, the Key Programming Using Two Programmed Keys procedure does not function. This PID only affects the Key Programming Using Two Programmed Keys procedure.

1. NOTE: The key used in this step does not have to be an Integrated Keyhead Transmitter (IKT) key. A conventional Passive Anti-Theft System (PATS) key can also be used, as long as it has first been successfully programmed to this vehicle.

Insert a programmed PATS IKT key into the ignition lock cylinder and turn the key from the OFF position to the ON position.

2. From the scan tool, enter TOOLBOX. Select: BODY - SECURITY - PATS Functions and follow the Integrated Diagnostic System (IDS) on-screen instructions to ENTER SECURITY ACCESS. For additional information, refer to Anti-Theft Security Access Anti-Theft Security Access.
