How do i figured out if i need a motor with or without crankshaft key?

I would recommend speaking to the folks selling the engine rather than fumbling through the information online. You can ask questions and get guidance from those who are selling it. As for this specific question, you haven't shared whether it's all wheel drive or front wheel drive, nor which of the 3 possible engine sizes you are seeking. Also, no one in this forum could know your source - and why they could be asking that question. Good luck!
