CarKey development with UWB chip possibility

Is there a possibility of developers having access to develop custom CarKeys system to install in their own cars with UWB & Bluetooth.

Currently theres no documentation or API and seems to be limited to large and select manufacturers.

The plan is to explore having remote start, unlock and GPS tracking using a microcontroller and W/R to the cars CAN bus.

Would I have to join the "Car Connectivity Consortium" (Unlikely to get in) or do I have to wait for a standard finalised?
