July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

No. 2 Additional Key Programming Procedure (Using the M-MDS): Conditions

There is only one valid key, or none.
NOTE:
- If a key ID number cannot be programmed and DTC 15 is displayed, the maximum number of programmed keys may have been reached. Verify the number of programmed keys using the M-MDS.
- 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.
