No. 4 Changing The Method For Registering Additional Keys: Notes
WARNING: This page is about a different car, the 2004 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- This procedure is for changing the enable/disable setting of the "No. 1 Additional Key Registration Procedure (Using Two Valid Keys)".
- The default setting for new vehicles and new instrument cluster replacement is "Enabled".
- By disabling the "No. 1 Additional Key Registration Procedure (Using Two Valid Keys)", only the WDS or equivalent can be used to register additional keys, thereby preventing two valid keys from being used to create an unauthorized spare key. This function is for use by rental car or other companies with vehicle fleets.
