Episode Information

"Lock 'n' Loud" is the twelfth episode of the second season and the sixty-fourth episode of The Loud House.


When Dad becomes upset with the children for never locking the front door, they decide to take home security to the next level.


Late at night, Rita and Lynn Sr. arrive back home after taking ballroom dance classes. After Lynn Sr. inadvertently twirls Rita into a rose bush, he heads into the house to get a first aid kit, but to his frustration, he opens the door without having to unlock it. He enters the house, and scolds the relaxing kids for not locking the door at night, reminding them that there have been some burglaries recently, and fears that their house might be next. Lynn Sr. locks the door, the kids go back to relaxing, and Rita is still trapped in the rose bush.

After finding out a robber's on the loose, the kids decide to defend their house.

In Lori and Leni's room, Lincoln admits to his sisters that their dad's right and that they need to be more responsible if they don't want their house to get robbed. Fearing on losing their possessions, as well as Lincoln stating that just locking the front door isn't enough if they want to protect their stuff, they decide to lock down the whole place, which the sisters cheer to.

Clyde arrives at the Loud House, but before he can walk onto the porch, Bobby, on a Segway while wearing his mall police attire, approaches Clyde and asks him for his name and business. When Clyde asks Bobby what he's doing, the latter informs that due to new security measures by Lori, he was hired to guard the house. Lori decides to vouch for Clyde, and he's allowed access into the house. The moment he steps in, he falls victim to two of Lisa's alarm systems, and flees before she unleashes a third one (an alligator pit). Clyde enters Lincoln's room, ready for the job, which involves the two listening to a police scanner. Later, when Lincoln exits his room, he sees his sisters stashing their closest possessions in the bathroom, since Lisa has a security camera installed in there. At the same time, Lynn is teaching Leni and Lola how to attack a burglar (which Leni fails at, since she finds the practice dummy cute, while Lola viciously attacks it). Walking into the kitchen, Lincoln sees Lana trying to teach Charles to be a vicious guard dog. However, Charles is too lazy to do Lana's commands.

Later that night, Rita and Lynn Sr. are about head off to dance class again, and Lynn Sr. lauds the kids on being more mindful toward security. Sometime later, as Lincoln and Clyde are sleeping, the scanner goes off and reports a 10–15. Checking the codebook, Lincoln discovers that the burglar has been caught, to which everyone cheers to. At that Rita and Lynn Sr. arrive back home. After Lynn Sr. once again twirls Rita into another predicament, he prepares to enter the house, only to once again, finding it unlocked. As the kids take back all of their possessions, Lynn Sr. once again scolds them for not locking the front door. When Lincoln informs him that the burglar has been caught, Lynn Sr. points out that there could be more burglars out there, but the kids pay little heed. Frustrated that nobody's listening to him, Lynn Sr. locks the door himself, once again forgetting to help out Rita.

The next night, Rita and Lynn Sr. once again leave for dance class, but the instant they leave, Mr. Grouse yells out that he has been robbed. When the Loud kids check up on Mr. Grouse, he informs that that several of his closest possessions have been stolen. Fearing that the (other) burglars could attack their house next, the kids decide to take their security to the next level. After stashing their possessions in the bathroom again, the kids prepare to do some improvements, which include Lincoln and Clyde filling a vat with bacon grease, Lola operating a searchlight, Luna, Lucy and Lily digging a ditch surrounded with barbed wire, Luan setting up numerous mousetraps, and Lynn recruiting her roller derby teammates to work alongside Bobby. When Rita and Lynn Sr. arrive back home, they're shocked at how far the kids are taking this. While Lynn Sr. admits that he appreciates that the kids are taking security more seriously, he feels they've taken it too far, and orders them go to bed.

Later that night, a shadowy figure comes out of the Loud House and approaches Mr. Grouse's house. The shadowy figure is revealed to be Lynn Sr., who had Mr. Grouse pretend that he was robbed so he can teach the kids a lesson. After paying Mr. Grouse with a basket of muffins, Lynn Sr. prepares to head back into the house via the kitchen door, but gets locked out by Leni, who was in the kitchen at the time. Realizing this, Lynn Sr. tries to climb through the kitchen window, but it turns out to be locked too. When Lynn Sr. falls over (due to standing on a tricycle), his noisiness catches Lincoln's attention. He peeks through his window, and witnesses a shadowy figure below. Thinking it's a burglar, Lincoln pulls on a string that rings a bell in everyone's bedroom, waking them up and telling them to take action. As Lynn Sr. tries to find another way in, he falls victim to the kids various traps, such as Luan's mousetraps, Lincoln and Clyde's vat of grease, the ditch that Luna, Lucy and Lily dug and Lynn's roller derby teammates pummeling him.

The family forgiving Lynn Sr.

Rita orders the teammates to stop attacking the intruder, since she recognizes Lynn Sr.'s dance shoes. Lynn Sr. lies by saying that he was out for a walk, and he got locked out. As everyone apologizes to him for attacking him, Mr. Grouse, with his face incredibly swollen, complains that the muffins Lynn Sr. gave him have walnuts (which Mr. Grouse is allergic to), and warns him that if he ever wants to pay him for pretending to be robbed, he should give him something he's not allergic to. With the truth spilled, Lynn Sr's family scolds him for lying to them, and he apologizes, saying he just wants to teach them to lock the door, so that he can protect his family. Rita and the kids are touched by this, and forgive Lynn Sr. As Rita and the kids are hugging him, Charles notices a couple of bacon strips stuck to Lynn Sr.'s butt, and advances towards him. Charles bites down on Lynn Sr.'s butt, causing him to cry out "OUCH!" in pain, and Lana, now satisfied that Charles did what she was training him to do, remarks "Finally!"


The burglar, Margo, Lainey, Maddie, and Nadia have no lines in this episode.

Those are some creepy smiles... and I LOVE them!

  • When Lisa dishonestly tells Lincoln she hasn't set up cameras in the bathroom, she makes the same eerily smile from Study Muffin.
  • Every Loud sibling's contribution to security:
    • Lincoln - Hearing the police scanner with Clyde and preparing grease for traps.
    • Lori - Asking Bobby to protect the house.
    • Leni - Learning martial arts to defend the house.
    • Luna - Setting barbed wire before the ditch.

    • Lisa - Installing alarms, setting up traps, installing retinal scanners, and making corporal search with metal detectors.
    • Lily - Digging the ditch.
  • According to Lori, she doesn't know what polka records, a black-and-white TV, or encyclopedias are, which seems to imply that she isn't familiar with outdated stuff.
    • This is somewhat ironic because Lynn Sr. owns a black and white TV in his office according to "Left in the Dark", which Lori must've seen at some point.
  • In the Brazilian Portuguese dub of the episode, Mr. Grouse's voice sounds different.
  • Royal Woods is revealed to have a low crime rate, and it's also revealed that most crimes that are committed in Royal Woods are minor (such as littering and neglecting to pick up after dogs).
  • Innuendo:
    • When Lucy imagines the burglar stealing her bust of Edwin, the burglar is shown turning the bust around before stealing it. The way the burglar does this resembles a person snapping someone else's neck, which can instantly kill people in that way.
    • Lisa accidentally reveals she installed cameras in the bathroom, meaning she's been watching people in the bathroom.
  • Irony: Lynn Sr. wished his kids to lock the doors and windows, but this became his obstacle to go inside his home unnoticed.

    • Lincoln's line, "Make that congealed bacon grease!", is changed to "Actually, enjoy the jelly, I guess..."


  • Lock 'n' Loud - The title of this episode is a pun on the phrase "lock and load", which means that a weapon is ready to be used.
  • Home Alone - The Louds putting traps around the house to catch the "thief" (who was Lynn Sr.) was based on a kid, who is home alone, who place traps in his home to stop two thieves from this movie.

  • Leni's smartphone cover is pink in this episode, but in "Changing the Baby", and "Cover Girls", it was blue.

  • When the Loud family members were scolding to Lynn Sr. about making a pretend rob, Lori's right eyelashes were missing.
