My 1997 Olds Cutlass Supreme will not start. There is silence when I turn the key in the ignition switch. The lights will go on, but the radio will not.

I tried to start my car.  When I turned the ignition key there the car did not start.  There was no sound at all.  The lights will go on, but the radio will not go on.  The security light had been going on before when the car would start.  My son replaced the starter and battery last summer.  Please help!  Any suggestions would be appreciated.  Thanks
