The problem sounds like the battery has run down. Even though the ignition is off, things like clocks and the radio draw small amounts of power to retain their settings, and the instrument cluster doesn't draw as much power as the starter. It usually takes about a month or so to drain the battery. Try jump starting the car, or put it on a battery charger for a while.

Most likely your timing belt gave way causing your valves and pistons to hit each other. Its time for a new engine.

that means your compression rings are gone

I have the same problem with my Z3 alarm going off, a local BMW specialist has traced it to the pitch sensor which has been damaged due to a water leak, the wires are also corroded. They have quoted £200 to fix it, but advise that the water leak is sealed first because it'll just get damaged again. I've had a look round and it appears the water is getting in by the off side light cluster via the boot gutter.

replace the starter and the flywheel-the bad starter has not engaged the teeth on the flywheel fully and has ground some teeth off so you'll fit that space every once in a while-cheers Denny
