Right, I'm aware that I may have just missed it but....I don't quite understand how Caleb got locked in.
Didn't he actually override the system for all doors to be open when a lockdown occurs for AVA to escape?
So....why are the doors suddenly sealed off again with the lockdown that he's trapped in?
As I said, I may have just missed that, but it did kinda worsen the ending for me a bit.
Ava's cunning.

Sometimes I think we're alone in the universe, and sometimes not.
I had the same question and was looking to see if anyone has answered before. Ava didn't reprogram anything after she killed Nathan. So, technically Caleb should have been able to escape once there was a shutdown.
The North remembers, and the mummer's farce is almost done
My thoughts exactly.

From the way I see it, he programmed it to be opened only during the power failure. I'm pretty much sure AVA turned the power back ON before disappearing from her locked room.

How was that escape going to go down, anyway? You didn’t
completely explain. You said you were going to get me drunk, take my
card, then reprogram the security protocols. But, reprogram them to -
what?
CALEB
To change the lockdown procedure. So that in the event of a power
cut, instead of sealing, the doors all opened
Then comes the revelation by Caleb that he had already changed
the code the night before.
Later ... after the demise of Nathan:
CALEB watches as AVA walking back down the connecting corridor to
Nathan's study ... then Ava passes straight by his door.
CALEB
Ava?
CALEB gets up. Goes to the closed door. Tries to open it.
There is a red LED light by the keycard plate. Locked.
He swipes his card, with his photo ID. The red light remains.
CALEB (calls out)
Ava!
With the power back on, the door in Nathan's study can only be opened by Nathan's keycard - which is now with Nathan, in a pool of blood, within the glass corridor. This keycard will soon be retrieved by Ava.
I'm talking about after that scene. Didn't Ava shut down the power? Wouldn't that mean the doors will be unlocked?
She don't speak. You bloody bastards cut her throat too deep for that. But she remembers.
Ava did not shut down the power.
It may be confusing, but the red lights and the monitors going off were the result of Caleb trying to use his ID on Nathan's computer. The ID was rejected, and the computer went into a safety protocol.
Hmmm... In that case I can only remark that it seems very careless of Garland to misuse a visual cue that's been so clearly established several times previously during the movie...
Duck, I says...
the door in Nathan's study can only be opened by Nathan's keycard
With the power up, I'd have thought Caleb could reprogram the security system though? That's the only thing that was bugging me at the end of the film. (It left me unsure whether he was in Nathan's room or not, but this thread seems to confirm he was.)
shareYes this is something I noticed on second viewing as well. Aren't the doors supposed to open when there's a power out? There was a power out when he was trying to use the system so therefore his door should have opened. If there is a reason for this to play out how it did, it was unclear to me, if not, it's a silly but major plot hole.
shareYes, Caleb programmed the doors to open when there's a power out. But Ava doesn't cause a power out at the end (she still operates doors on her way out), so the doors don't open. Caleb's programming, initially to be used against Nathan to help Ava escape, was consequently used by Ava to trap Caleb so she can escape on her own. Caleb would have needed Nathan's key card to escape (as some doors can only be opened using Nathan's card), but Nathan had his key card on him as he led on the floor, bleeding to death. Therefore, Caleb will never be able to escape that room so long as the power is on.
I think that's the point. Ava uses her AI to manipulate Caleb to get her own way. She got in the helicopter to have a life in the outside world where nobody would ever know she's an AI. Nobody else, other than Nathan and Caleb, knows she even exists. It's the perfect escape plan. That's how I saw it anyway.
Not only that, But he also programmes for Natan to be locked in after that. And since he is the room Natan wood be in, he is now locked in.
shareThe doors unlock DURING the power outage, but once the power comes back on, they lock again. As per Caleb's hack, which reversed the procedure.
shareCorrect, ... so Caleb would have to create a power outage.
Even so, how would he get home? He likely would not have access to a security coded computer or communication system.
"Even so, how would he get home? He likely would not have access to a security coded computer or communication system."
The entire ending to the film is purposefully ambiguous. The story is essentially already over when Ava gains freedom. What happens to her after she experiences her first intersection, what happens to Caleb, how is Nathan's stronghold supplied, even if the helicoptor pilot isn't allowed to get closer than the landing spot, etc. etc. etc.
All of those questions and details are unimportant to the story told once it's completed.
The movie suggests that strong artificial intelligence is the next evolution of sentient life. The story of Nathan, Caleb and everyone else became irrelevant once Ava won. It has reached technological singularity, a point when computer can out-think human, thus nobody can possibly predict it's next step. Humanity has come to an end.
shareThis has been answered by user 'xenopharb', but people keep discussing it and that user's reply is buried, so I'm replying to the OP to hopefully bubble to the top.
Caleb wasn't trapped in Nathan's room by Ava having turned the power on or off.
He was trapped because in desperation, he tried to access Nathan's workstation with his own keycard.
As Nathan explained earlier in the film, Caleb's card does not have access to all areas. It's not unreasonable to believe that Nathan's workstation would have more than just a red-light and rude beep, like a door that Caleb is not allowed to open. His own workstation could easily have stronger protocols, such as locking the room.
And the security systems around Nathan's workstations are different from the power-outage systems.
With the power back on, his security systems on his workstation would work normally, locking the room on any attempt for unauthorized access to his workstation.
