Battery keeps draining and key is stuck in ignition.

I have a 93 gs and just got a new battery 2 weeks ago but for some reason it keeps draining within a 24 hour period. I just replaced the alternator belt, but am not sure if it’s the alternator or a bad cell in the battery.

And for my key when the battery is charged, when I’m driving it the ignition feels a little warm and the key won’t come out when I turn the car off. When the battery is completely dead the key comes right out.

Need help please.
