Key Programming - Switch State Control

KEY PROGRAMMING SWITCH STATE CONTROL

NOTE:
- The spare key programming switch is a diagnostic tool-programmable switch which provides the capability to enable/disable the customer spare key programming procedure. This procedure is in the Owner's Literature spare key programming procedure or under KEY PROGRAMMING USING TWO PROGRAMMED KEYS. This programmable switch is provided as a convenience for customers who may not want the spare key programming procedure available to the vehicle driver.
- The spare key programming switch state can be viewed with the instrument cluster SPAREKEY PID.
- If the SPAREKEY PID reads ENABLE, up to 8 keys total can be programmed into the instrument cluster using SPARE KEY PROGRAMMING - UNLIMITED KEY MODE. If the SPAREKEY PID reads DISABLED, the Key Programming Using Two Programmed Keys procedure will not function. This switch is set to ENABLE when the vehicle is built. This PID does not affect the Key Programming Using Diagnostic Equipment or the Spare Key Programming - Unlimited Key Mode procedures.

1. Insert a programmed passive anti-theft system (PATS) key (or integrated keyhead transmitter [IKT]) 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 on-screen instructions to ENTER SECURITY ACCESS. See ANTI-THEFT SECURITY ACCESS.
3. From the scan tool menu select: CUSTOMER SPARE KEY PROGRAMMING ENABLE and press the tick mark. CUSTOMER SPARE KEY PROGRAMMING ENABLE - spare key programming procedure is accessible. CUSTOMER SPARE KEY PROGRAMMING DISABLE - spare key programming procedure is not accessible.

NOTE: The default setting on delivery of all new vehicles is ENABLED, when viewing the instrument cluster SPAREKEY PID.
