Won't start, no dash lights. on 2006 Ford Taurus

Has a new starter and battery. I turn the key and nothing. Usually when I turn the key to the on position several dash lights come on(check engine light etc)but now I get nothing. I'm thinking the ignition switch went bad?? Security light keeps flashing like when you leave the car locked. Other than that there is no power anywhere except for headlamps and interior lights.

Is the security light flashing quickly or slowly?

Have you checked fuses in the battery junction box and the inside panel as well?
