Something wrong in the start circuit. The fact that dash lights come on indicates the ignition switch seems ok.- power is getting to it and exiting it.
The next place to check is the starter: before taking it off and have tested, do this quick test: when the car won't crank over, pull off the small wire on the starter solenoid-mounted on the starter-and see if that wire has power when the key is held in cranking position. You will need a helper to hold key in start, and an inexpensive testlight or volt meter to see if the wire has power.
This wire is the signal wire from the ignition switch to activate the solenoid and allow battery power to turn the starter motor on.
If the wire has power and still no crank, then the starter or solenoid is the problem, assuming battery and cables are good and connected tight. Pull the starter off and test it. If starter is good, probably the solenoid.
If the wire has no power when key is held in crank, the problem is in the circuit from the ignition switch to the solenoid-includes the neutral safety switch, maybe a starter relay, too. One would begin testing by checking for power on the start wire exiting the switch with key in cranking pos. If good there, test the neutral safety switcfh. If you have manual transm, the switch would be on the clutch pedal. If automatic, have a shop locate and test that.
Good luck- often, not always, it is the starter or solenoid. But do that check for power at solenoid , first.
