Is there any fluid that can unlock my motor?
Clarification: What is the mileage, which engine? Also, describe the conditions under which your engine seized.

If the motor is seized based on what you described, then damage has already been done unfortunately. You are looking at a new engine.
You could try squirting a few shots of PB Blaster or WD40 down the spark plug holes and let it sit for a while, if it has rusted pistons and rings from sitting. Beyond that, we don't know what caused the engine to seize.

Start shopping for a replacement engine. As others have said, no fluid will "unlock" an engine that seized up under those circumstances. The only time such a thing might help is if an engine is stuck because it's been sitting around unused for years and pistons are stuck in the bores.
