Video tutorial

In this video, see how to start a Peugeot 3008 that, although it opened normally with the remote, would not start with the electronic key and button, as it displayed "key not detected". For these cases, there is a slot on the left side of the steering column where you can place the key, and the vehicle will recognise the key - even if it is flat - and will start anyway.

This was not the case here as the remote had correctly opened the door.

Subsequently, the starting function resumed normally. The reasons can vary, such as a signal drop or temporary shielding: however, we have learned something important.
