How Power Door Locks Work

[@jamesmclachlan9835]

every video on youtube should be as clear and informative as this. bravo

[@YZRandomE]

It's always interesting to see how much engineering goes into these little things we take for granted.

[@speedkar99]

Agreed! So much for something we take for granted

[@lanimereala]

"We are going to have to remove the door panel to have a closer look" *jump cuts to a door panel-less door and a car-less door* this is dedication right here.

[@speedkar99]

Love it! Chopping that door was leisure

[@lanimereala]

@@speedkar99 holy hell speedkar responded. huge fan. learned even more from your videos than in mechanic training.

[@fuzzyelectrons]

Absolutely brilliant high-speed crash course of power door locks. Now I have an idea what could have happened to one of my doors that won't lock.

[@speedkar99]

Thanks

[@tome8373]

This is one of the most under-rated youtube channels of all time

[@speedkar99]

You think so? 😊

[@tome8373]

My uncle showed me your videos and they are absolutely invaluable to identify and trouble shoot problems as you go over the whole system explaining logically how it works instead of what is wrong with something. And I am a tremendous fan of the toothbrush pointer.

[@mrlds3202]

Also the talking speed is fine for me personally.

[@speedkar99]

Okay good to know

Great engineering . I always wondered how everything worked.. now I know muchas gracias.

[@oldtoolslovers3271]

Hi Sir I've been a subscriber to your channel for a few months. I learned a lot from your videos. I want to thank you.

[@speedkar99]

I'm glad you learned alot. Thanks for subscribing!

[@mrlds3202]

The complexity in car vehicles is just insane. No wonder why Tesla is the first startup in decades and even they have had insane amounts of production issues!

[@speedkar99]

It sure is quite a complex machine, and has taken alot of growing pains to get it right... especially right off the assembly line.

[@inductor1.77]

Also, electric cars are soooo much simpler than a gas engine.

[@Smileyguy-jy6xm]

"The power door locks can be operated using 3 methods"...was waiting for using my brother's toothbrush as a slim jim to be on the list. In the midst of this great presentation we still got the toothbrush & trousers as an added bonus. Well done Sir.

[@speedkar99]

Lol

[@michaelbezoski3096]

Love those technical operational explanations. I would venture to guess a lot of dealerships have your channel for techs to looks at. I know I would. Thanks a bunch!

[@speedkar99]

You are welcome, and I'm glad to be a resource for others.

Awesome video man.

[@speedkar99]

Thanks

[@topgrain]

Thanks for a great video that I need now. The driver's door on my 93 Honda Accord EX (power locks) is locked and cannot be opened from inside or outside. I was able to get the door panel off from inside without damaging it too much, but what I'm wondering is if it is possible to reach the latch and operate it by hand to free that door. There is no real visibility, but I can feel several mechanisms back in there, but have no idea what might unlatch that door. Perhaps there is a hole or slot that provides access to that latch.

[@nalvarez3505]

Another excellent video

[@speedkar99]

Blimmey you certainly know your locks. My car door bounces wont stay closed when car is frozen up, 10 minutes and its thawed out and works fine. Any idea how I can prevent this happening? Thanks.

[@Enigmaafk]

Just one click and all that is going on , Not like the old day everything was manual . Did the lock work after this video?

[@speedkar99]

Nothing works after I am done with it 😁

My actuator for a nissan quest is so expensive. Can i find the plastic gears somewhere?

[@speedkar99]

Junkyard

[@howtobebasic2122]

do a video on How heated Seats and Heated Mirrors work.

[@speedkar99]

Good idea

[@francisreymaneja8000]

How do you bring back all those springs and stuffs on the actuator itself

[@betabilly]

Cool, but what if neither the indoor handle, key fob, outside key lock or indoor lock button does not unlock the locked door? I have a 2000 Buick Century and can not open the passenger side front door. I know something is jammed but how do you service the power lock with the door closed and locked? I'm not going to saw my door!

[@mohammadal-khatib98]

Good one, as always 👏👏

[@speedkar99]

Thanks

[@thenerdshow]

so when the power goes to the lock actuator, is just a single 12v pulse? Or does it supply constant 12v?

[@TheUnknownPerson]

Really good video, learned a lot👌

[@Armen_]

My Honda Accord 2003 keyless entry only locks/unlocks the passenger side rear door even when I use driver side door buttons It only locks/unlocks passenger side rear door, after watching your great video I will be more confident (maybe) to open up the door panels to look into them. Thanks.

[@speedkar99]

Yes look into it. It could be worm lock actuators

[@Armen_]

@@speedkar99 thank you.

[@CryptoLosOne]

I'm interested in upgrading door locks for for GM classic cars from 1965 -68. Any ideas which locks would be compatible?

[@christojoseph2476]

[@hatem0]

Can you now assemble it back? 😂 But a very informative explanation

[@Tony32]

Great video!

[@speedkar99]

Thanks

[@surajdharmavira3614]

Thanks for info. I think most important part is the black plastic cover which acts as anti theft

[@ScubaCat3]

I like how I saw a blue toothbrush flying around when I hovered my mouse over the video tile. I should probably now watch the actual video - I bet it's even better!

[@speedkar99]

Haha those video previews got you

[@MoritzvonSchweinitz]

This is your first video where you lost me somewhere along the way - which is of course not your fault! But there where to many half linkages and tabs and stuff.

[@speedkar99]

That mechanism is sure confusing to be honest. I sat behind the camera to figure it out myself before filming

[@farmlandtiger1377]

Thanks, professor!

[@kennethtanaka883]

When are you going to disassemble manual transmission from an FWD car? I can't seem to find any explanation or videos on how it works on FWD cars

[@speedkar99]

When I can get my hands on one. I'm sure it's principles of operation are the same between FWD and RWD with the main difference being the shift linkages

[@antonyviser]

Wow so much I still need to learn

[@speedkar99]

Glad you learned something

[@TauriCai]

Thank you so much for the excellent explanation, I'm pretty sure I'll review all the procedures in my head before I press the botton(serious face).

[@speedkar99]

That's how I think too

[@richardhead8264]

_So much complexity_ for one sub-system of an automobile! I wonder how manufacturers ever recoup development and piece-part costs. Are such mechanisms as this used on several models in order to increase quantity-discounts?

[@speedkar99]

I sure think they would reuse parts in different models. It's beneficial to consumers too because parts are cheaper to find and replace

[@i-will-get-you-there]

Nice. Thanks for the video. Love to see late model hybrid SUV over view. Cheers

[@speedkar99]

Good to know, I'll keep that in mind

[@jesussaves6671]

Chirper: Where is the theft deterrent alarm chirper located on the Solara?

[@marandapetty3460]

This what keeps the door locker on the inside from going up and down even though the lock switch works on the door? But doesnt electronically lock the door?

[@surajdharmavira3614]

Thanks

[@speedkar99]

[@acrepairnearme]

Very interesting!

[@casketblack5660]

Dude, that little latch that we take for granted and couldnt give a F about, really is quite amazing. I wonder just how many designers and man hours its taken since cars were invented for something as small and complicated yet simple to evolve to what youre holding in your hand there. All the head aches gettin all those little arms just right and dealing with patent issues etc just to get it to function and then to get it to work not 50 not 80 but 100 percent every time before the age of computers. I mean shit, the same can be said for everything people use obviously, but.. idk, trip.

[@speedkar99]

I agree, it's so complex to think of all the engineering that goes behind these parts we can't even see!

[@creativejunior7060]

Cool, i can use that lock with my homemade burning laser to control the switch of my homemade pressure washer so i can clean my motorcycle easily.. Thank you so much.

[@paulparoma]

Use it in conjunction with your homemade cellphone to lock, unlock or remote-start your homemade car.

[@pashakrai4034]

I’d be more interested in seeing • How to install a power lock if there isn’t one. • How to replace a manual HVAC to Auto Climate Control. • Upgrades to Audio system. • Sunroof Rattle repair and other car enthusiasts content 👍🏼 Keep it up, man 👌🏻

[@speedkar99]

Thanks for the suggestion

[@toddhammett6930]

So say my door locking system works fine when it’s warm but once the temperature gets cold, the locking no longer works but the unlocking works just fine. Why would that be?

[@speedkar99]

Worn lock actuator

[@tinuthomas531]

Is no one gonna talk about the Supra in the back???

[@speedkar99]

Thanks, you are the only one to notice it

[@SuperSmellyBob]

That actuator is a pain in the ass to remove from a 2005 Neon. I've tried several ways with no avail.

[@speedkar99]

Some cars don't make them as easy to remove and you have to replace the whole thing

[@howtobebasic2122]

They sure did!

[@Lori00000]

I’ve been looking for something like this. A better explanation of why my driver door doesn’t open from both inside or out when locked. I’m going to check today and I’m going to be upset if I’ve had child lock all this time 😔 thank you so much for your explanation.

[@speedkar99]

You are welcome. It's pretty cool to see the intricacies of how locks work

[@danielchapman1930]

Now to add a sheet of tinted plexiglass (3M) into a steel frame, incorporate this mechanism... And I have a new door for my business/club/camera room🙏 Might even turn it into a sort of powered window for my bedroom. (Like a fibreglass garage door that retracts into the ground, controlled with something like a 'dim light switch') Next project is to buy a hybrid with CarPlay and include the entire electrical system; automatic bedroom windows instead of shades, secure looking, could program keys to serve as 'employee tags'; wifi, tv, radio, ios connectivity built-in, could always upgrade/modify later on to add Nebula Max and Dyson Fans... Imagine the power of that air conditioning system when I link a huge propane tank, or 4 🤔💭🧠🤯 Might even pair the keyless entry with my Nike for the sake of innovative convenience, and use the wiring for headlights to electrify that frame/handles/fence... would probably go as far as to ask a relative for the propeller from his old aircraft to make some stand out ceiling fans, using the accelerator with the door to give circulation a 'boost' when someone enters.

Thermister to prevent overheating

[@paulparoma]

I am not crazy about these newer power lock systems. Rather complex and sometimes temperamental. I never had any trouble with power locks on my old GM and Ford cars (all the parts were metal, including the door switches), but I can't say my 2005 Toyota has been 100% reliable in that department (all cheap plastic crap).

I locked my key in my Toyota just last night. This is hurtful.

[@speedkar99]

[@yingcluk]

I dislike Nissan's door lock actuator. They are known to be broken in just few years of use. I had to replace my girl friend's Nissan driver door lock actuator which stops working in less than 5 years of manufacturing date. I have used 3 Toyota, and their electrical door have never had any problems.
