Thanks, how do I disarm the immobilizer with a remote-less key, and the engine light flashes continues when you turn the ignition on, same car you sent me the diagrams.

I would do a hard system reboot, remove the negative battery cable and hold it to the positive terminal for 1 minute and then reconnect. This guide can help as well:
