Programming & Compatibility

This smart key requires professional programming to the vehicle's immobilizer and proximity system before use.

The AES 6A credential and remote/proximity functions must be correctly registered to the vehicle. Compatibility should not be determined solely by physical appearance or FCC ID because Mazda uses the same FCC family across different button and P/N configurations.
