Will not crank at all

Car listed above is the Contour model. I started it it came on for 3 seconds and went off. I started again it did the same and since then it wont crank at all but my car lights, dash lights, radio, and windows all work. Got it jumped didn't crank so I bought a new battery. The alternator and starter are good and when I turn the key on I can hear the fuel pump click and come on. About a month ago when I turned off my car the key was stuck so I put my foot on the brake put it down in neutral and back up in park and it released my key. It did that maybe 10 times throughout the month and I repeated the same steps to get the key to release. The day it stopped cranking the key didn't give me any trouble. Other than the key getting stuck I never had any other problems. I am so lost. Please if you could be so kind to help me.
