Brennan Went to Film School: Unlocking the Hidden Meaning in Insidious: The Last Key

“Brennan Went to Film School” is a column that proves that horror has just as much to say about the world as your average Oscar nominee. Probably more, if we’re being honest.

WARNING: THIS ARTICLE CONTAINS DETAILED SPOILERS FOR INSIDIOUS: THE LAST KEY. READER DISCRETION IS ADVISED.

Blumhouse had quite a year last year, didn’t they? In addition to having three number one hits on their hands, the racial satire Get Out is their first horror entry to get awards traction thanks to its deeper themes. Now that everyone is starting to take the company and its work a little more seriously, it’s time to bring out the big guns and dive right into some deeper analysis into a much more unlikely subject: Insidious: The Last Key. The fourth entry in their tentpole haunted house franchise might not seem like it at first glance, but it’s the Get Out of the Me Too era, telling a story of women’s struggles while predicting the downfall of powerful, abusive men that started to occur during its production process with eerie accuracy.

No, seriously. Let’s start by taking a look at the villain. Unusually for this franchise, the baddies are both paranormal and human: halfway through the film it is revealed that the haunting victim who has called Lin Shaye’s Elise and her crew is also a sadistic killer who has chained up a woman in his basement. This is also revealed to be the very same thing Elise’s father did many decades before. The film implies that both men are being influenced by the key-wielding demon that inhabits the house.

Key imagery is very important to the film as a whole (I mean come on, it’s literally in the freakin’ title) and its themes of Elise arriving to her childhood home to unlock the secrets of her past. But there’s more than one meaning to that imagery, and understanding those meanings is the key to unlocking the subtext of the film, if you’ll allow me a really obvious pun.


The demon KeyFace might be influencing the men, but they’re still receptive to the idea. That’s because he’s awakening something that was already inside them. KeyFace represents the pure male id; the unconscious, animalistic desires and drives that lay buried in the psyche. He’s not forcing them to behave in this way, he’s just unlocking their darker impulses.

It’s no coincidence that the demon’s lair is the bomb shelter basement. The house has now become a road map of her father’s mind, with his strongest emotions (and the literal place where he keeps his abused women secreted away) hidden in a sublevel that isn’t visible from the surface. This is the very same basement where he locked up Elise while punishing her for insisting that her visions were real. He wanted her to keep her psychic gifts locked away, probably so she wouldn’t discover his own submerged secrets.

Elise encounters a variety of keys during her journey that allow her to penetrate deeper and deeper into The Further, the house, her past, and the hideous truth about the men in her life. These keys unlock doors, suitcases, chains, and cages, but the most important unlocks the truth… and turns the attention of the evil upon her and her two nieces.

The probing of these women ignites the fury of KeyFace and he takes her niece Melissa into the basement (another buried sublevel that must be unlocked), inserting a key into her neck and rendering her mute, then stealing her soul with a second key plunged into her heart. He is only vanquished when Elise and her other niece Imogen team together and use a family heirloom – a whistle – to summon Elise’s mother’s spirit.

On the surface, this seems like an inspiring story of three generations of women helping each other to face a great evil. This is certainly true, but now we have the key to understanding exactly what’s happening here. When a young woman discovers the abuse being perpetrated in her house, the figure of pure, wicked male desire literally steals her voice, silencing her. In order to restore that voice, another woman who knows the truth must very literally become a whistleblower.

…Did I just blow your mind?

At its heart, Insidious: The Last Key presents a world where women must rely on other women to provide them a voice and their very survival in a world dominated by powerful men and their ugly, dirty secrets. Secrets that they will do anything to keep locked away. There may be slightly more ghosts in Insidious than in real life, but that’s a frighteningly close parallel with the ugliness currently being revealed in Hollywood – as well as the world at large. It probably won’t tear up the Golden Globes next year, but this film is just the next important stepping-stone after Get Out in Blumhouse’s use of the genre to dig deep into the real life horrors plaguing our society.


Brennan Klein is a writer and podcaster who talks horror movies every chance he gets. And when you’re talking to him about something else, he’s probably thinking about horror movies. On his blog, Popcorn Culture, he is running through reviews of every slasher film of the 1980’s, and on his podcast, Scream 101, he and a non-horror nerd co-host tackle horror reviews with a new sub-genre every month!
