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 ENABLED if more than 2 keys need to be programmed into the PCM. For
additional information, refer to Key Programming Using Two Programmed Keys See: Accessories and Optional Equipment/Antitheft and Alarm
Systems/Testing and Inspection/Programming and Relearning/Key Programming 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 PCM SPAREKEY PID.
NOTE: If the SPAREKEY PID reads ENABLED, up to 8 keys total can be programmed into the PCM. For additional information, refer to Key
Programming Using Two Programmed Keys See: Accessories and Optional Equipment/Antitheft and Alarm Systems/Testing and

affect the Key Programming Using Diagnostic Equipment procedure or the Spare Key Programming - Unlimited Key Mode procedure or the Spare Key
Programming - Using Diagnostic Equipment procedure.
