Continental CMKG2 Body Controller Module
Product Information
The CMKG2 (Body Controller Module) is a component of a driving authorization system for a car. It is part of a system that includes the vehicle key, the UHF antenna module, and the UWB antenna module (in some markets). These components exchange encrypted data to allow car access, start the engine, and locate the key. The vehicle key features three buttons for car access. Pressing the dedicated button sends RF authorization data to the control unit, which opens the doors. The second button locks the doors, and the third button opens the trunk deck. Additionally, there is an optional PANIC button for the North American market.
In addition to using the buttons, car access can also be granted by touching the door handles. The vehicle key is activated by the LF antennas’ magnetic field (21.85 kHz), controlled by the CMKG2. The key sends encrypted RF data (315 or 433 MHz, depending on frequency variant, and 7 GHz UWB for some markets) for authentication. The CMKG2 receives this data from external antenna modules and unlocks the vehicle doors. If the battery is low, car access can be achieved using an integrated mechanical emergency key. The vehicle key is placed in a dedicated slot inside the center console, where it is wirelessly powered by a magnetic field (also 21.85 kHz).
Please note that this device is not available for general purchase and can only be installed by trained specialized personnel from the car manufacturer.

Operation Instruction
- The CMKG2 (body controller module) is a component of a driving authorisation system of a car which further comprises of the car’s vehicle key, the UHF antenna module and (for some markets) the UWB antenna module.
- The components exchange encrypted data for car access, to start the engine and to locate the key. The vehicle key contains three buttons for car access. By pressing the dedicated button the vehicle key sends over RF authorization data to the control unit to open the doors. A 2nd button releases data to lock the doors. A third button is dedicated to open the trunk deck. An additional “PANIC” button is implemented optional for the North American market.
- Moreover car access is also released after touching the door handles. The key is waken by the magnetic field (21.85 kHz) of the LF antennas, driven by the CMKG2. The vehicle key sends over RF (315 or 433 MHz, depending on frequency variant, as well as 7 GHz UWB for some markets) encrypted data in return for authentication. The CMKG2 receives this RF data from external antenna modules and unlocks the vehicle doors.
- In case the battery is low, car access is possible by means of an integrated mechanic emergency key. The vehicle key is then to be placed into a dedicated slot inside the centre console to be powered wireless by means of a magnetic field (also 21.85 kHz).
- This device is not freely available on the market and is installed only by trained specialized personnel from the car manufacturer.
