Mazda MZ24 / MZ34 Transponder Key – Texas 4D63 80-Bit Chip

Mazda MZ24 / MZ34 Transponder Key – Texas 4D63 80-Bit Chip

Aftermarket transponder key designed for compatible Mazda vehicles using the MZ24 / MZ34 key system and Texas 4D63 80-bit transponder platform.

This key features the MZ31 / X249 standard key profile with an integrated 4D63 80-bit transponder chip. It uses a 10-cut blade configuration and is intended for select Mazda keyed-ignition applications requiring both mechanical key cutting and vehicle-specific transponder programming.

Programming & Compatibility

This transponder key requires mechanical cutting and vehicle-specific immobilizer programming before use.

The MZ31 / X249 mechanical profile may appear across multiple Mazda applications, so a matching blade profile alone does not confirm electronic compatibility. The vehicle must specifically use the corresponding 4D63 transponder immobilizer system.
