No. 4 Key Additional Programming Procedure Changing: Notes
WARNING: This page is about a different car, the 2007 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- This procedure is performed for enabling/disabling the "No.1 Additional Key Programming Procedure (Using Two Valid Keys)" setting.
- This procedure is possible when the vehicle is new, and when replacing the keyless unit with a new one.
- If "No.1 Additional Key Programming Procedure (Using Two Valid Keys)" is set to disable, the additional key programming can be only performed using the M-MDS preventing the forging of a spare key by using two keys that can start the engine. This function is for use by rental car agencies or other companies with vehicle fleets.
