Key Programming - With 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 - WITHOUT PROGRAMMED KEYS  . PID SPARE_KY must be enabled for this procedure to operate. To enable this PID, perform KEY PROGRAMMING - SECURITY ACCESS PROCEDURE  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, check for Diagnostic Trouble Codes (DTCs) and repair as necessary. See SELF-DIAGNOSTIC SYSTEM  . Maximum of eight 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.
