No. 2 Key Additional Programming Procedure (Using the WDS or Equivalent): Condition

There is only one valid key. Or, there is no valid key but there is a card key that can start the engine.

NOTE:

A maximum of eight keys can be programmed for 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 WDS or equivalent and verify the number of keys that have been programmed.
If eight keys have already been programmed, and it is necessary to program other keys, the previously programmed key ID numbers must first be cleared. To clear the key ID number, refer to NO.3 PCM REPLACEMENT PROCEDURE .
