Key Programming - Using 2 Programmed Keys

NOTE: This procedure will only work if 2 or more programmed ignition keys are available and there is a need to program additional keys. If 2 keys are not available, perform KEY PROGRAMMING - ERASE ALL KEYS & PROGRAM 2 KEYS . Parameter Identification Data (PID) SPARE_KY must be enabled for this procedure to operate. To enable this PID, perform KEY PROGRAMMING - SPARE KEY PROGRAMMING SWITCH  and enable spare key programming switch. If programming procedure is successful, new key(s) will start vehicle and THEFT indicator light will illuminate for 3 seconds. If programming procedure is not successful, new key(s) will not start vehicle and THEFT indicator light will flash for one minute (after flashing for one minute, THEFT indicator light will flash fault code). If necessary, repeat programming procedure. If programming of key(s) is still unsuccessful, perform self-diagnostics. See SELF-DIAGNOSTIC SYSTEM . A maximum of 8 keys can be programmed into system. If procedure is not performed as outlined, programming procedure will end. Ignition keys must have correct mechanical key cut for vehicle and must be an encoded key.
  1. Insert the first programmed ignition key into ignition lock cylinder. Turn ignition switch from LOCK to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to LOCK position. Remove ignition key from ignition lock cylinder and go to next step.
  2. Within 5 seconds of turning ignition switch to LOCK position, insert second programmed ignition key into ignition lock cylinder. Turn ignition switch from LOCK to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to LOCK position. Remove second ignition key from ignition lock cylinder and go to next step.
  3. Within 10 seconds of turning ignition switch to LOCK position, insert a NEW unprogrammed ignition key into ignition lock cylinder. Turn ignition switch from LOCK to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to LOCK position and remove ignition key from ignition lock cylinder. The NEW ignition key should now be programmed. To program additional key(s), repeat key programming procedure from step  1.
