Car won't start every time. If I leave it sitting awhile it will start

What is your question?

My car won't start at times but all the lights are on and radio is playing...I turn the key off and let it sit for awhile and it starts up but once I turn it off it's dead for awhile again. The little red light comes on when it doesn't start. I had this problem before and it cleared up for awhile but now it's back. I also dropped the key and broke it just this past Saturday but put it back together. I've been told it could be the security system, a loose ignition wire or I simply need a new key. Other than this once the car is started it runs great

What makes this problem better or worse?

Nothing it just has to sit awhile

How long has your 2014 Chrysler 200 had this problem?

Happened 2 months ago but went away. Now it's pretty much every other time I try to start it
