Car does not start on 2006 Kia Sportage

I tried starting my car and it does not do anything when I start it. The radio, lights and all else works. Is it the starter or the starter switch?

First you have to tell us if the engine cranks or not.

If there is no sounv
when the key is turned to the crank position, you have a battery, connection, or a starter problem.

check the battery for correct voltage-- should be 12.0v or higher.

Next, check the connection at the battery, be sure it is tight, both terminal/

next then check the starter by tapping on it with a metal object.
Could be the transponder in the key, the ignition switch, wiring, transmission gear position switch, starter, battery cables...many things could cause this.
