In the following video, you will see how it is possible, in case of emergency, to start the car engine by bypassing the immobiliser. Test with the coded key first and then with a non-coded one to notice the difference, following the procedure as titled.

In the second case, with the non-coded key, install the Fiat Bypass from OBDII in the compartment to the left of the steering wheel, specifically in the only serial socket available. Disconnect the existing connector and connect the bypass as described.
