Lock 'n' Loud

"" is the sixty-fourth episode of The Loud House.

Plot
When Dad gets upset with the children for never locking the front door, they decide to take home security to the next level, and the kids end up overdoing it.

Synopsis
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 tries to head 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 forgetting to lock the door at night. When Luna questions what the big whoop is, Lynn Sr. informs them that there have been some burglars recently, and fears that their house might be next. After Lynn Sr. locks the door to show how easy it is, the kids go back to relaxing, but Rita is still trapped in the rose bush.

In Lori and Leni's room, Lincoln admits that their father is right, and says that they need to be responsible if they don't want any of their stuff stolen. As the sisters hug what they don't want to lose, Lincoln states that just locking the front door isn't enough if they want to protect their stuff. They need to lock down the whole place, which the sisters cheer to, even Lily, who yells out a triumphant "Ga-ga!" and holds up toy keys in her hand.

Clyde arrives to 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 for 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. After drinking some bad tasting coffee, the scanner informs them about an 11-25 (which means failure to pick up dog poop).

When Lincoln exits his room, he witnesses his sisters stashing their closest possessions in the bathroom. When Lincoln questions Lisa why the bathroom is the chosen location, the latter states that she had cameras installed in the bathroom since last year. When Lincoln is about leave, he hears Lynn shout out that there is a burglar present. When Lincoln checks up on Lynn, it turns out she's actually teaching Leni and Lola how to attack the burglar. While Leni fails miserably due to finding the dummy cute, Lola viciously attacks it after Lynn informs her it stole her tiaras. When Lincoln walks into the kitchen, he notices a hooded figure entering from the window. It actually turns out to be Lana, who is trying to teach Charles to be a vicious guard dog. However, Charles is too lazy to do Lana's commands.

Later that day, Rita and Lynn Sr. are about head off to dance class again, but not before Bobby stops them to ask them for their names and business (only to unintentionally state them himself). Sometime later, as Lincoln and Clyde snooze off, the scanner goes off and reports a 10-15. As Lincoln checks his code book, a 10-15 means that the burglar has been caught. As the Loud kids begin cheering, 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 the kids for forgetting to lock the front door. When Lincoln informs him that the burglar has been caught, Lynn Sr. rebuffs that there may be other burglars out there, but the kids pay little heed. Lynn Sr., fed up, goes downstairs and 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, the latter informs 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 with Bobby. When Rita and Lynn Sr. arrive back home, they're shocked at how far the kids are taking this. Because of this, Lynn Sr. orders the kids to head off to bed.

Later that night, a shadowy figures comes out of the Loud House and approaches Mr. Grouse's house, and knocks the door. 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. Leni, after grabbing a glass of milk from the fridge, hears a twig snap outside. She peeks out the door, and seeing nobody, closes it and locks it. Realizing he got locked out, 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 while struggling to open the window), his noisiness catches the attention of Lincoln. 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.

Rita orders the teammates to stop attacking, since she recognizes the dance shoes present. When it is revealed to Lynn Sr., he 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, his face incredibly swollen, points out the muffins have walnuts (which he's 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 beans spilled, the kids and Rita angrily scold their father for lying to them. Lynn Sr. apologizes, saying that all he ever wanted the kids to do was to lock the door because he didn't want to lose his closest possession: his own family. Touched at his heartfelt apology, the kids and Rita hug him in gratitude. As they hug, 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 remarks "Finally!" due to Charles doing exactly what she wanted him to do.
