The key is not recognized.

The process of identification of the key and the start up
- the transponder in the key will be powered by a ring-antenna and sends back the data of the key to the EWS
- the EWS checks the data and gives an enable signal to the DME and to the starter
- after the start the EWS sends new data to the key (changes the code)
