"Card not detected" error in the Peugeot 508, what does it mean?
Years 2010-2018

Answer

The "card not detected" error indicates a problem in interfacing the key to the control unit. The problem can simply be caused by the key battery being flat, in this case a quick test can be carried out using the spare key or by replacing the battery. If it is not a problem with the key, then it could be a software malfunction and a reset of the on-board computer can be attempted in the workshop.
