Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

The security light flashes to indicate that there is a malfunction in the immobilizer system and then the PCM (engine computer) does not energize the fuel system to operate to start the engine.

This can be caused by a failed transponder in your key or an issue with the coil in the steering lock that reads the key.

The codes will have to be checked using a scan tool that can plug in and communicate with all computers.Once this has been done any codes set need diagnosed and repaired to correct this fault here.Most common is the key itself needing replaced but the coil can fail as well.

Unfortunately there isnt a way to bypass this here.
