Yesterday getting into my Supra, I unlocked the driver's door and the alarm went off, so I put the key in the ignition and the alarm turned off. I then tried to start it. It wouldn't start, so I got backout, shut the door and locked it again, then unlocked it. It started right after that.

If your battery is not holding a charge, you got a bad(dead) battery. To test your alternator, after you start the engine, put a voltage meter on the battery (red -pos/black-neg) and if you see 13-15 volts, it's charging. I'm not sure what the total voltage should be from a Supra alternator, but if it's putting out over 13 volts, your battery is charging.
