How do you start the engine on a 2017 Citroen C3 when the car says the 'key not detected'?

There is an emergency key scanner in the Citroen C3 models that have remote key starting for times that the remote key detector is not working or the battery is flat in the remote fob.

Use the procedure below to perform an emergency starting of the Citroen C3
