No.1 Additional Key Registration Procedure (Using Two Valid Keys): Conditions

Have two or more valid keys.
NOTE:
- A maximum of eight keys can be registered for any one vehicle. If key registration is not successful and DTC 15 appears even though the procedure was performed properly, use the PID/data monitor function of the M-MDS and verify the number of keys that have been registered.
- If eight keys have already been registered, and it is necessary to register other keys, the previously registered key ID numbers must first be cleared. To clear the key ID numbers, refer to " NO.3 KEY REPLACEMENT PROCEDURE (CLEARING PREVIOUSLY PROGRAMMED KEY ID NUMBERS, KEY RE-PROGRAM) ".
