Quick answer

There are currently 2 methods for cutting a new auxiliary key blank. A. Auxiliary Key Trace Cut Method B. Auxiliary Key Code Cut Method 2019 and newer models require a 10-digit key code to accurately cut keys 5-digit codes CANNOT be provided for 2019 and newer vehicles (the traditional 5-digit code from the key tag or driver's door lock cylinder is not sufficient and will not be issued for key cutting on these models). Only Mazda-approved key cutting machines can process these 10-digit codes. Many older key machines do not support 10-digit codes and cannot be updated to do so. In these cases, dealers will need to purchase one of the newer Mazda-approved key cutting machines capable of handling this requirement. For a list of current Mazda-approved machines and purchasing options, refer to the Mazda Dealer Equipment Program or view the current Mazda approved key machines below.
