If the security light is flashing, the system is shuting down the vehicle. My concern is that one time, it may not start for you, and based on where you live, that doesn't sound good.
As far as a sensor, if the security light is flashing, then all sensors are doing what they are designed to do, shut down the vehicle. I will tell you that for testing of the security system, you need to go to a dealer. They will have the proper test equipment, others won't.
