First Security light began flashing with no start of course.Then Security light, Alt charge and Temp light went out all together? So now no Security light nor Alt charge or Temp light comes on when ignition is turned on for start.

Have you had the battery tested yet and made sure the battery cables are clean and tight? For the lights not coming on? The security light on those are usually a key issue or a bad ignition cylinder but some diagnosis would have to be done.

Yes the battery is fully charged and tested ignition vats system n found failure in reader and that is when all this occurred.Also cables are clean and tightly installed though I did unhook battery once to let system reset itself. I'm wondering if it could be a "relay" that somehow all three are tied to.
