Special Tool(s):

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, refer to 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. Using Two Programmed Keys
- The spare key programming switch state can be viewed with the PCM SPAREKEY PID.
- If the SPAREKEY PID reads ENABLED, up to 8 keys total can be programmed into the PCM, refer to Key Programming Using Two Programmed Keys. If the SPAREKEY PID reads DISABLED, the Key Programming Using Two Programmed Keys procedure will not function. This switch is set to ENABLED when the vehicle is built. This PID does not 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.
