91 Park Ave won't even try to start

So my car just randomly decided to stop trying. It was working fine one moment, then half an hour later it won't start. The car turns on and i can use all the other functions but when i turn to start it it does nothing. Its not the key because the security light isnt coming on. Any ideas? Thanks in advance

The first thing to check would be the battery. It may have just enough power to run the auxiliary devices but not enough cranking power to start.
You may also want to check the starter solonoid.

So its not cranking at all? If so, then check your battery terminals for corrosion and tightness. Also check for tightness on the bolts on the solenoid. Assuming the battery is good, then I would suspect the solenoid.
