How does a Door Handle work? 

I didn't think it'd be that complex, impressive. I like these :)

I think you are the first RU-vidr who explains everything with great knowledge with finest animation.

what a stunning presentation. I am so impressed by your animation work.

So much better than the last 5 videos I watched on locking mechanisms 5 stars helped me fix a busted door.

Never have I seen such a useful video on such a simple subject

Dude! How much time does an animation like this take :0??

Holy flip, THANK YOU SO MUCH!!! I'm not even kidding, I accidentally locked myself in a room with the door handles (and therefore also the spindle piece) taken out, because I thought the door would just open back up or something if I pulled on it. I know shutting the door in the first place was probably a bit of a moronic move, but this video was ACTUALLY a legitimate lifesaver for me, because I seriously couldn't have gotten out, otherwise. You are absolutely amazing. Thank you so much for this!!

animations and explanations are precise and good..keep going for other such day-to-day simple working system which most of us don't know!

The earliest I remember wondering this was when i was 4 years old. It is a question that has plagued me for years and years (and I really wanted to take them apart but I thought "people won't be able to get through doors"). This video has instilled in me a sense of childlike joy

You make things so understandable and your narration is really appreciated.

I tried to fix my door lock once and I failed 😢 now I realized it’s actually very complicated inside . Very inspirational work! Thank you ❤

I can’t even begin to imagine how the development of this 3D video took place. Not my wheel house at all, but I recognize the mad skills! #awesome

This was the video I didn’t know I needed. I’ve disassembled plenty of door handles, but now I know how and why everything happens! Keep it up! Amazing work! 10/10

It's fascinating that this design hasn't changed much in a long time. This helped me fix my broken bathroom doorknob, the springs weren't retaining as they should be, and shaft was warped, not bad for a 12 year old knob but it had to go.

i’m seeing if door knobs have any wheels in them

I have installed countless door knobs/handles in my adult life, but I learned a a lot from this video. Thanks...

Seeing the montrosity of the things inside the handle made me already give up on trying to understand, but once you assured me of showing one piece at a time and clearly showed their function and purpose individually, while gradually showing how the "chain reaction" works, it all made sense. Perfect!

AMAZING WORK! Keep it coming, please.

Hi! So I got locked up for a 6 hours straight without foods and drinks, and you literally saved my life! Thank you for this video!!!!

You are doing a great work which will satisfy mechanical engineering students

I had this weird thought when I was trying to sleep a few weeks ago. I wondered how door handles worked. I tried thinking for myself how they work but couldn’t quite do it. I couldn’t let go of this thought, I thought about it everyday. I tried thinking of different ways it could work but I came up with none, I couldn’t wrap my head around the concept of a door handle. It drove me sick. I couldn’t sleep anymore. Whenever I closed my eyes, all I saw was a door handle. It taunted me. Taunted me for not knowing how it worked. It ruined my life. I couldn’t do anything anymore, not even the simplest of task. I was slowly going insane, and I knew it. Doors became an obstacle in my everyday life, I no longer even saw the doors, only the door handles. And they were taunting me. I couldn’t take it anymore. I was on the verge of a break down.That’s why I came here, to finally get the answer. To get the key back to my sane life. And I can tell you, it saved my life. It really did. I don’t know what I would have done if it wasn’t for this video. I’m a recovering door handle addict, and this is my story.

I swear...I just locked myself in my room after only installing the "latch" piece in the middle with no knobs and of course after closing the door to see if the "bevel" was facing the right way. This showed me how a door lock mechanism works so I learned how it must be manipulated with no knobs.. new vocab words in "" Thanks Jared guy.

The ammount of engineering that goes into such a trivial thing is quite humbling

So I got locked into my own room because something broke in my doorknob causing it to stay locked, because of this video I was able to disassemble the doorknob and remove it’s insides. This was very helpful. Thank you!

This is probably the most informative video ive seen on youtube. Thanks for this.

Superb animation, well-done! I especially love that you named all the parts, as that it makes it easy for me to describe a problem to a support desk. Instead of, "Well the problem is in the cylindrical thingie that moves when the doodad is turned," I can correctly say, "the problem seems to be in the latch assembly because the cam drive units aren't moving smoothly, but the handles with the rosettes work fine." Thank you!

This is the youtube channel that deserves to be subscribed. It has benefits in life.

Excellent video! My doorknob came apart and was a frustrating puzzle until I saw this. Thank you!

good job this dserves more vews this helped me out alot

Excellent explanation and animation!!! Thank you so much!!! :)

Thank you so much for posting this. It helped me a lot when my door handle broke and I did not know why.

I rarely comment or like any video but this One i couldn't resist myself commenting and liking. You deserve it. So much hard work done by you can be seen in this video

The animation in this video is amazing. I really needed to see how a door handle worked for a project I am working on and this was by far the best thing for comprehension. I am subscribing and hope to see more Mr. Owen. Good job and thank you!

Hey man You are doing a great job by making these animations. Explanations and animations both are amazing. Keep doing what you do. You do inspire many mechanical engineers! Thank you The world needs creators like you

i know how a door handle works. im an adult. but this video defo deserved a watch lol. nicely done dude

I hope EVERYTHING is illustrated by your animations

Excellent graphics and explanation - thank you.

Your video, animation, and explanations are so crisp and simple. Very well done, I look forward to watching your other videos as well.

Thank you so much. This helped me open a broken door knob that was locked from the inside. I fixed it as a 14 year old and my dad couldn’t.

you deserve a lot of praise...great job.

Amazing! I just learned so much.

Jared, you are an artist at animation and also at explaining things. Much success to you in all of your endeavours !

Wow,what a technology behind the door lock,I can't believe

I have literally been wondering this my entire laugh, it was literally a mental relief to finally understand door knobs 😂

I would have liked but that pun was to much to HANDLE

My handle doesn't have a lock. Actually, I don't have a handle. Actually, I don't have a door. Actually, I don't have a room. I sleep on the couch.

I accidentally "locked" myself in a room by closing a door that had the handle removed (d'oh!), and was able to get it open again thanks to this video. Saved my life! Amazing explanation, thank you so much!

jared owen you are a deadset legend

This was so helpful. My door handle broke in a weird way this morning and I'm trying to fix it. This helped give me an idea of the problem.

That pun was amazing

I'm very impressed with this video. For someone who knows nothing about door handles, I know have some knowledge. I appreciate the time put into the animation and the down-to-earth explanation. Well done.

Opened my jammed lock with this mechanism. Thank you so much.

Could you do a European door handle

The Lock Picking Lawyer: interesting!

Thank you very much. I just fixed my jammed door because of your video. 😊

Animation:100% Content: 100% Labeling: 100% Quality and completeness: 100% Flow of Presentation: 100%

Great video, detailed explanation, and nice animation. But, what about spherical handle that have a push button lock? Is the lock has the same mechanism? Thank you

I haven't seen handles like that. In Northern Europe at least we have tall replaceable handle mechanisms which hold the springs inside them. Would love to see a video on these.

When I am super stressed out I can always just open these videos and I will soon be completely immersed. I wish I could double like all of them!

Thank you for your time and effort, Jared. Excellent video and tutorial.

I can do some home repairs, I can build shit, but changing a lock and door knob is the Bain of my existence

I couldt HANDEL it my self😂 thanks

Incredibly well done - fantastic work!

Door lore is love, doof lore is life.

door lore

I have never ever seen anyone to presentation like this way! Awesome.

Wow. That was amazing. So much information that we use every day without giving it a thought. Great narrator. Thank you 🙏

I got to see this first hand yesterday when all the Handels in my house were removed

Those door locks suck. All it takes is a long fingernail and putting it into that outer lock area. Bam. Door unlocked I had one of those locks on my bathroom door, and my siblings always unlocked the door when I was taking a poop

The video made me feel like i can fix all the broken door handle in the world.. lol so useful! Love this

Hey, I am working in ironmongery industry for the past couple of months, Now you 've clarified a few of my doubts. U 've done a great job. Keep on updating videos like this.

Door lore

You are teaching me things I never thought about knowing. The amount of time, skill and hard-work you commit is unbelievable

what an amazing video. This couldn't be more clear; very impressive

Jared Owen: 0:48 Engineer: Sorry, we have to keep it vertically. Me: wtf

Sad that all of that technology can usually be defeated with a pen knife or credit card.

What a professional job you've done. Very helpful too. Thank you so much.

That's actually really interesting. Something which we use everyday and take for granted.

Roblox Doors Lore

Just found this. Thanks so much for all your work, this is extremely high quality content.

Great work, thanks Jared!

Got locked in my bedroom now I'm over here studying the anatomy of the freaking door handle to avoid breaking the whole thing down

This is more simple than I thought

As a guy who makes doors for a living u did a really good job explaining how the door handle works

U saved my life if it wasn’t for this video … my kids and I got trapped in our bedroom due to a defective door knob. My kids often watch your videos and my youngest gave me the idea to watch your video on how door knobs work! We were able to dismantle it and was out of the room. TYSM!

Wow! What a brilliant way to explain something that we use in our houses hundreds, if not thousands of times a day, but quite likely don't have a clue as to how that "thing" works. Thank you.

Fantastic video!! Thanks a lot for this.

I really needed to pee but i was stuck in my room. Videos about fixing jammed door latch all weren't helpful, because they were all showcasing it from the outside of the room or had the wrong lock type. This video was exactly what mine looked like so it helped a lot in figuring out what I'm dealing with. I'm finally free and don't have to pee in a bottle in my room. Thank you so much.

You are answering some of my biggest childhood questions... THANK YOU!!!!!

This is so oddly satisfying!! I love it!!❤️

I learn a lot from you

Wow! What a great video! Great job all the way around.

Can't tell u how much I really appreciate these. Thank u will all my heart dude for taking the time out of ur life to learn, animate and teach such valuable info. Thank u so much.

Incredibly well done! Subscribed!!

Your voice is calming.

Thank you! Great effort!

Cannot hide how I am amazed by the animation you make bro...keep doing what you like....CONGRATS!!!

Impressed. Thank you.

This was very useful. Most videos just give you the most simple reasons a door won’t latch. And though I already knew that it was probably the spring causing my latch failing to return, I can check the cam and driver to make sure they aren’t worn or broken.
