WARNING: This page is about a different car, the 2010 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

Have two or more valid keys.
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.
- If "Customer spare key programming disable" is selected, perform additional key programming using the M-MDS. (See NO. 2 ADDITIONAL KEY PROGRAMMING PROCEDURE (USING THE M-MDS) .)
