Could you open a gate? It's simple for a native speaker

Greetings warriors!

In a hypothetical situation. Let's suppose that a have a gate, and this gate has an automatic voice-system for closing and opening. Let's suppose as well that I'd like to say to this gate the following: "Gate, open yourself" or should I say "Gate, open it" or "Gate, open" or "Gate, open itself". Which one is correct?

Remember, that's a hypothetical situation.

Thanks in advance!
