Kia Rio wont start, no lights or anything when I turn the key on.

When I turn the iginition I don't hear any noise or see any lights. But as I turn the key back to me the lights will show up (dim and jumpy) all while I hear a clicking noise, also I notice while I do this the gauge for the temp of the car will go from below the cold line to just above it. However when I try to start the car again no noise, lights disappear and the temp gauge falls back to under the cold line. This has only happened once but in that instance the car turned back on without issues (I had even turned it on and off a couple of times to see if it will happen again with no issues). The next day it turned on with out issues again, but today its not turning on at all.
