D2 key stuck

Nothing special. Since it's NAS, make sure it's in Park.

if the key is in the off position then the tumblers are probably broken in the cylinder. If it's not all the way off then the Brake Shift Interlock system is malfunctioning. That system has 2 jobs. First to keep you from selecting drive without your foot on the brake, then it's second job is to make sure you don't take the key out unless the car is in park.

I would get the lock cylinder out of it and get a better look at it. My guess would be a damaged cylinder. I think if you took all the tumblers out of it the thing wouldn't care what key you used.

On my D1, a number of times, if I accidentally attempted to remove the key without being in Park, the key would get stuck in the ignition, sometimes a few attempts, one time a couple of days, disconnecting the battery seem to help

I always used a hammer to jimmy mine loose.
