First of all, you need to know what the sentence above means.
"In general, to enter a car and unlock it, you need ___."
The options are llaves (keys), antenas (antennas), espejos (mirrors), and tanques (tanks).
So obviously, based on the context, the correct answer is going to be llaves.

The correct form of the verb is close
