if the car key light is ON it means something is wrong with car's immobiliser aka security system and it means it will never start untill the issue has been solved

take your car for diagnostics aka scan a code will tell you what is wrong

yes your car has been locked from starting

Just a suggestion

by the way you describe it you have an ignition problem start by checking the battery terminals, they have to be tight and free of corrosion and acid. after that check the spark plugs maybe they are too worn out that are keeping the car form starting also check for spark see if they are sparking if not, you might have a bad coil.
but it seem you have a sometimes start sometimes don't situation so there is somethig loose so after checking battery and spark plugs make sure everything is connected properly the coils, and all the sensors connections wiggle them and make sure they have a good contact. the starer hot wire and ground too.
after that if it still don,t start put the parking brake turn the ignition on as if you were cranking the engine and tell some one to tap the starer with a hammer,s handle and if it stars you have a starer that have worn brushes and need to be replace. other thing you can is to jump the starer selonoid
