In the movie Ex Machina, Caleb reprograms the security system to unlock all doors when there is a power cut. When the 10PM power cut happens Ava gets out. In the end when Caleb is locked in, he tries to access the computer. At this time there is a power cut. Shouldn't this have triggered all the doors to be unlocked for him to escape? Instead we find Caleb smashing a locked door with a stool, which means the doors didn't unlock when the last power cut happens. They don't show Ava changing any security protocols or anything. How come the doors don't unlock?



Best Answer

It's a little clearer in the screenplay that the computers shut down, not because the power had gone out, but because Caleb attempted to use his own access card in the card reader. Since the power was never out, the doors remained locked.

He runs back to the monitors. On them, AVA has reached the MAIN ROOM. She walks straight to the smashed window. And steps through.
CALEB sticks his card into the slot by NATHAN’S computer. Instantly, all the screens die. Replaced by a single word.

Why was Caleb locked up?

Caleb was trapped in Nathan's room, simply because his keycard wouldn't have access to Nathan's room.

What happens to Caleb in Ex Machina?

Ava cuts the power, and Caleb tells Nathan that he suspected they were being watched, and therefore modified the security system the previous day. Seeing Ava leave her cell, Nathan knocks Caleb out to try to stop her. However, Kyoko stabs him. Nathan breaks her face apart, but is then stabbed by Ava.

How did Ava manipulate Caleb?

Ava successfully seduced Caleb into setting her free using self awareness, imagination, manipulation, sexuality, and empathy. She fooled Caleb into thinking that she actually cared for him when in reality her sole priority was to escape.

Does Caleb ever escape Ex Machina?

In the ending currently playing in theaters, Ava leaves Caleb to die and is seen escaping Nathan's vast compound in a sun dress via a helicopter and its unsuspecting pilot. Their conversation is muted from a distance and we do not see exactly how she convinces him to fly her to the nearest city.
