MasterKey III MK3 Key Programmer for Renewing Used Electronic Keys

The MasterKey III is a device and software solution designed for programming and copying electronic keys for vehicles and other applications.

The primary function of the MasterKey III device is programming and copying electronic vehicle keys. When an immobilizer ECU is available, the device can also recover lost keys by reading energy-independent memory. Additionally, the MasterKey III can generate pre-prepared vehicle keys.
