What a great repair. You wouldn't get this from a "warranty" type repairer, just more proof that Right To Repair is critical to keeping technology out of landfills.
It's about time and money. This thing probably costs 10 bucks to make for the car companies, with 100,000% markup.
@@larrybud Exactly. Someone with the skills needed to to board-level repairs like this is going to charge way more than it would be worth to repair the key fob, when the dealer can fix it in 10 minutes (most of which is waiting for a machine to cut the key) with a part that barely costs anything to make and plugging a tool into the car to learn the new key fob. If they are charging a dime over $50, they had better be coming out to your house to program the key (they can look up the cut on their computer system based on the VIN, and cut it before they come out)
@@thetechconspiracy2 I would look at it like this, if there would be more skilled people like him that would increase some competition which may decrease repair costs.
@@thetechconspiracy2 board level repair (I've been getting into it as a hobby) will always be a thing due to greed seriously my 07 dodge i brought a already cut key that needed to be programmed to the dealer they charged me 120ish CAD and the reason i brought them a key i cut is because to get a key supplied by them was 300+ CAD FOR A 07 DODGE
@@thetechconspiracy2 I usually fix stuff like this for my freinds , for free . The challenge of not being beat by a chip .
Yes you can renew this chip check vvdimb tool. Good work with this chip👏 🙌
Yes, you can even make keys with VVDI MB in all keys lost situation and add key, so long as it's FBS2/FBS3
That’s what I love about UA-cam. Viewers coming up with the solutions. Everyone wins.
That looks like damage from a small screwdriver being used to open the FOB housing when changing a battery. At first look I knew that pin should be repairable, but I would have used an exacto to scrape the overmold down. The other thing I would suggest is TakPak CA glue over the part of the chip you ground away.
Okay! I was watching this video and thinking, "how though?" how do you get that pin broken. But yeah - inserting a pokey thing to try and get the fob open to change a battery could for sure do that.
Yeah, those fobs have a hard life, and are covered with a conformal coating from the factory. I'd definitely have sprayed a bit more conformal coat on to cover that part
As I am repairing a lot of remote controls I can absolutely confirm! And it's the same for all these broken coils in FOBs...
It’s a real pleasure to see how you approach a problem, formulate a plan of action, then always do your best for the customer! A true professional.
There is a way to read the codes from the chip if you really need it I could send you a link to the video on here and they have some of the necessary tools on the video as well
@@fredob7207 please share link
I feel like I'm late to the party discovering this channel. My favorite thing: that I see the TRUE JOY on your face when you are able to fix something!
Sure, you provide real value for your customers and that's your job, but you look like you genuinely are excited and pleased with yourself when you're able to troubleshoot and fix a problem, and the fixer's watching you (myself included) know and love this feeling. You're very positive and a pleasure to watch, keep it up!
you mean when WE are able to fix something, lol
You can reprogram these chips with special tools like VVDI Benz VVDI MB BGA tool or a CGDI Prog MB Benz Car Key programmer, love the videos and thank you
Chip is encrypted to prevent it being read and cloned.
Nicely done. I work a lot with forensic data recovery from vehicle components and sometime, chips damaged by corrosion (flooded cars), fire or several mechanical damages exhibit this problem. I approach it in the same way, usually there's plenty of connectors still buried in the epoxy. Things get a little more difficult with QFN or BGA packages.
Iam a car programmer this chip can be just writing you cant read dump from you have to read eis dump generate keys and write new dump of key generate to this chip nec using ak500 or cgdi or vvdi mb key programmer regards all the best
I always look forward to a new uploaded video from you, Alex. You level of soldering and repair work on tech is just out of this world.
Been doing this since 1984, I just use a dermal cutoff wheel, I the last 11 years I use boiling acid, we decap our chips to do FIB work on prototype chips (mostly making metal layer changes and some other stuff). We also decap for thermal imaging for latch up debug/etc.
I'm sorry did you say boiling acid?
@@carpethooligan yes
@@Ozzy3333333 Sounds interesting. I'd like to know more!
The solder wick they sell is top notch. I bought 3 spools of it. Use it every day. Now my 10 spools of Goot Wick sit in a box, unless I need it for something very small. Now, if they could get this premium wick they sell in different sizes, now you REALLY got something. Oh yeah, and I bought the UNI-T thermal camera, LOVE IT! that thing has already paid me back.
@@fluke196c maybe he means amtech?
congratulation, this is a hardcore repair. you deserve the designation as a professional.
I wonder how this pin suddenly became “unsoldered”
i think it's corrosion. the car from 2004.
Was broken off, the chip looks like it was impacted
I would suggest screwdriver popped into the unit to pry it open, and slipped knocking cap off and destroying the corner of the IC
@@xxxxbigdavexxxx correctamundo!! I sell replacement covers form some car keys and those Mercedes need some "help" from a needle nose plyers, not a screwdriver.
Mechanical damage from opening it. A tool scraped across the PCB ripping off that capacitor and damaging the legs on the chip.
Funny how we end up right back to the rtr .. the dealer has the equipment and software to read and write to that chip..They want you to come back so they can wax you that money! Good repair boss! Keep up the good work of sticking it to the man!!!!!!
Very unlikely that the dealers have access to the tools to read or write to that chip for security reasons (any data should be encrypted and obfuscated to keep thieves from reading the data from a fob and making a copy). The manufacturer is the one able to make copies, but $500 USD and up is price gouging for a device that costs at most a few dollars to manufacture.
Another absolutely amazing fix. I love how you look for solutions, not problems.
Great job, did it start his car though. The original issue was the doors worked but would not start car.
I'm surprised this doesn't need a coating with UV treatment?
As always amazing work with these device's.
it's tinned, that's enough to prevent corrosion for the foreseeable future, and there's no need to insulate it from anything electrically. Do you see any UV coating on the other pins?
@@ubergeeknz I was just seeing part of chip exposed and my ocd nature kicked in and thought oh dang shouldn that be covered.
Ah, I saw the screwdriver comment below, I was wondering how the damage happened. Brilliant repair job
If anyone knows if that NEC chip can be cloned, the MHHAuto forums is where to look
you can program Bench keys whit an other programmer that called : CGDI MB programmer its not cheap i hope this help you out in your job.
You can't copy the NEC chip, they are programmed to be serially matched to the car. the read.write bit is burned out when it is programmed.
The probabilities of being able to read the programming of the microcontroller are very slim. I mean, security-wise that makes sense. If I have that device, then all I have to do is to get a job as a valet. There's a high chance that if u try to read from it, it'll erase itself.
Well, that certainly looks like a totally unattended fault of the keyfob. It definitely doesn't look like someone has messed up with a way to big soldering iron and no clue what they do, at all.
with the aytel maxim im 608 programmer you can program these keys
Wow, THAT is a new level! I was sitting with my mouth open: "How in the world did this repair work?" Absolute top-notch repair, great job!
Hi. You can read the Nec chips, but all my posts about that, are deleted.
In some ways it's nice to have more theft protection with these modern keys, but then stuff like this happens and I want to go back to technology of the 90s
Amen
Solution would be if companies and dealerships charged a fair price for a new Fob instead of ripping off their customers because there's no other option.
Even more annoying in this case is the knowledge that 2004 Mercedes security is well and truly broken wide open to any car thief anyway, in this case it's just a very expensive replacement for the customer. All the thieves can program a key almost instantly.
Always good to think outside the box when it comes to repairing. Nice work.
He thought thru the box (best of both worlds) as soon as he picked up the Dremel to get access to the pin. Yes, well nice work indeed. Also, the humility and common sense to testing out upon a donner chip, shows the level of professionalism that you don't often see - somebody sure of themselves but not over cocky and with that - truly defining the word professionalisim.
I don't think that Alex knows what it is to think inside the box. As long as I have been watching, that is simply the way it is. He has made me more adventures. That has made me a better repair person. Thank you Alex for putting a higher standard on professionalism.
How can i send my rtx2060 to you for repairing from india
The grinding pen and flux have saved many boards here, won't be without them. The flux is easy to clean, and the pen makes short work of damaged or missing areas on boards.
On reading the chip, normally the programmable portion of the chip has a "fuse" that is purposely blown after programming to prevent accessing the code that would allow you to read and then program a new chip. Find the datasheet for the chip and look up the program method. If that's the case, now we know why Benz can charge $1,500 for a fob.
You're amazingly creative with the repairs. Everyone should strive to be at your Level of dedication to get the repair done.
How these thing happens automatically, like this key. Who enter in the chip area and damage the leg... Or customer do this for his/her curiosity😆😆😆?? 💙💙
big fall then open the casee then hit the leg
I had one of these keys run over by a bus (long story, left it out near my work van). It was smushed. Still worked and held together. I feel like this was a customer damage situation. They are extremely stout.
Amazing work!!
Thanks for these videos, Ive learned so much on smd work from these and have done several repairs.
Cheers!!!
I learned something new today with this video...keep on making other techniques on repairing SMD components...Thanks
I cant get through to anyone at northridge.....how the f do i get in touch with you...i just want some sort of info on my part... 3 months with no reply...
@@joeds3775 Jo ed's....they have my part since October...have not received any info as to progress...you think 3 months without any correspondence is fair?
600-1200 USD for a key fob? I'm disgusted!
Good save!
In my last job, the benches in the cleanroom each had a 1/4" vacuum port for slurping up debris. By making a small filter in a plastic box it enabled us to wash areas with IPA, and suck-up as we cleaned, leaving no residue. A cheap vacuum/suction pump with a filter would be a great help with SM work like this.
I always look forward to a new uploaded video from you, Alex. The experience you share and your advice is invaluable.
I did think before i see you perform the operation .i was thinking about grinding it .
Did you put solder mask on it? I really enjoy your videos.
I can understand why the want to protect they programming on those chips. There is a 100% chance shady individuals would abuse it to create illegal copies of the fob which could then be used to easily steal the vehicle at a later date. It's a pain, but I get the reason for the security.
Found your channel recently and have been hooked. Your process is brilliant and as others have said it is your approach to the repairs which makes the difference as well as your capabilities and craft. Been doing these sort of repairs for years but with optics only and normally head gear but things just getting too small and uncomfortable for me so Looking at buying the microscope kit in UK 10 MP with 180x lens. can I ask what megapixel your sensor is?
I do not understand how this happned at all - maybe damage caused during replacing a battery or something?
Either way I know these fobs are expensive as well as finding someone to reprogram them... had a scary moment recently when I put one through a washing machine, thankfully it came back to life especially after I researched the cost of buying just a new blank fob + programming.
Alex you can read the NEC chip if you have the right tools. I did this many time!!!
Hello Alex.
There is a way to program this keys. But probably you don't do a car 🚗 repair ☺️ in your experience. There is exclusive software what can allow you to do this. Number on the chip is added to program. Look at this if you have time. You are my favourite repair man. I can send you link or picture if you like to reprogram the key's.
THANKS FOR YOUR VIDEOS.
Chip can be replaced. Autel is selling the programmer for mercedes and bmw fob chip's. And most of the time you don't need to repair just buy the new aftermarket fob and program it on ecu.
Dealership: “We’ll have to replace your fob. Are you paying in good or platinum?”
Me: “Well, I can see it will pose its own obstacles but on the whole, let’s do it. How much? Let’s just say you sort out the pizza guy. And don’t forget the gratuity.”
Edited to Add: I’m an Electronics Diagnostician and SMD reworker.
I always look forward to a new video from you and the funny thing is,,, I know nothing about electronics🤣🤣🤣🤣🤣🤣🤣🤣🤣
This case "the pin is gone". Amazing skills thank you
Dear sir i m from pakistan
My hp 4045s laptop after closing lid/restart/shutdown show blank screen with caps lock blinking.
After removing battery few times it starts normally.
What causes this behviour please
I am amazed at your confidence and approach
Fantastic! On top of the brilliant repair successfully completed right before our eyes no cost for donor part, just a large amount of brains mixed with flux & solder as well as some more wear on the grinding bit. Big boss has now made a small profit to go towards purchasing more awesome equipment. Absolutely brilliant!
It's better to put solder mask to pin for more protection
Ремонт на компонентном уровне, сейчас такое почти ни кто не умеет
Ive had luck getting a solder ball to stick the broken legs little bit of exposed metal, although its probably not a long term solution.
Huh…so German cars don't work without parts from Japan…I never would have guessed that.
(I already knew it)
Big brother I have subscribed ur chanel and follow ur every link but still I am not getting updated on ur recently posted video, no notification no msg, no email... Wjat shoukd I do
Thanks for this vedio
I have a problem with my PC HP elitbook 840 G2 laptop Can you help me plz.
You can dump the programming of the key. That is if you have time to find a backdoor into the encryption. However if you have near to no knowledge in programming, I would not even consider in trying this. Since you are a busy man, I highly doubt it will be worth your time.
That chip is ROM once is precoded and programmed to a car it becomes locked and unusable for programming to another car, it can not even be unlocked like other manufactures can be. Nice job bringing that fob back to live, but i'm wondering what could've cause that leg to break in such manner. Never seen any mercedes fob in such condition without any other noticeable adjacent area damage to justify it.
How would you repair a keyfob that draws to much current? I have a keyfob wich constantly draws 3ma. The buttons are working, so it's not sending all the time. There is no corrosion on the board.
if this happened to a macbook and sent to genius bar..
tech: "It seems it has a broken leg on IC, it would cost $1,200 + labor so we can replace the whole board."
beautiful, fluid fix! Grinding down that IC was nerve-wracking to watch lol
Hello, I have a problem with an a520m aorus elite motherboard. When I turn on the PC while I am in the Windows installer, the screen turns black and the keyboard turns off and I can't even turning it off with the button on the cabinet will it be a problem of the motherboard that has a burnt circuit?
Theres a NEC programmer you can get for $50-$80 dollar range that should be able to program these chips.
Talk more about John Deer and McDonalds please. Also about shady lobbyists.
You are not supposed times as the ID of the NEC chip that is the reason why it is in there. This chip must contain a 'secure element's it is hardened against casual read out and even chip invasive attempts to read it out.
The secure element contains the device key that is derived by Mercedes when the keyfobs are personalized. After personalization a fuse inside the Chip is blown that will make tge reading or writing of the key impossible.
If you are using the key fob session keys are derived inside the Chip and transmitted in some form to the reader which can calculate back a know herself that authenticates the fob, because the algorithm will only give the right known secret when the cryptogram was encrypted by the Key fob with a correctly derived key.
Otherwise, it would be too easy for car thieves to clone the key find and steal the cars.
So good the first thing which crossed my mind when I saw the broken pin. Would be possible to grind bit of chip off with grinding pen for the fix?
Very happy to see at end of video it worked. This question bugged me for quite a while.
I have a syringe of Antec 559 flux, how the flux do I know if it's the good (real) stuff?
Fantastic repair. A nice big slap in the face for 'throw away' culture. Kudos.
Programmable chips are burned by their fusebit factory so they cannot be copied
Certain devices have been sold on some sites that claim to copy the binary file from such microcontrollers, but it is not known if it works.
After Xbox360 kamikaze mod nothing is impossible lol
There are no problems, only challenges 💪🏽
no way this is worth it. greymarket can make keys for cars no issue. people as strealing 2021 cars by breaking in and pluging into the OB2 port and making a key. they can for sure do this old thing
You can get a programmable key for under 100$ then pay a locksmith to program it
sir i would like to ask, if chip at one electronic device replace such as nintendo/sega/which is keep memory, it will be lose programing?
I really wonder how this chip leg got ripped off so badly. Did the customer tried to fix it before? I mean this is not happening by itself isn‘t it?
the recoding is done in the car using the ignition module , ecu etc, you need a programming level diagnostic machine and also a numeric code that can be obtained from the dealer network.
unsure on merc keys but it varies as to whethe you need a "virgin" - as in , program once and never recode fob, i dont think that you do , in any case aftermarket nes are usually available...
AUTEL IM608 with APB pcb to read n clone
Sir, can you also repair dash cam that doesn't turned on? If you do please let me know, thank you.
mini diamond file does a similar job ......... 40 years ago when those tools not avaliable
Any idea what happened to this? I've only ever seen missing components like that cap from a short.
I do wonder what happened to cause this break, maybe a fall with the other part coming off and smacking the pin out of place?
Did someone damage it when trying to change the battery? Amtech is the best flux.
NorthridgeFix, what microphone and setup you use?
What kind of microscope setup do you use? ditto on all the great repair comments/
this reminds me of repairing dallas clock chips, ive got a few systems with them and at least one wont boot with a null clock set which is kinda problematic on those things
This video should be used as an example for Right To Repair.
You can program nec chips with a $5000 tool and the vehicle there
Funny how people who buy Mercedes and other fancy cars are always the ones who never have the money to just get a new key.
When you get a new fob the key is not programed the ecu of the car is programmed to the key the key has a code that it send over 2 or more data pens to turn a car on so no you can't reprogram them because the locked and you can't unlock them the mainbord for the car has to be reprogramed to the key
How do you use multi meter sir? Model number and brand pls.???????
This video Saved my life, Absolute Legend!
Yes. Fixable. Chip away around the broken off pin to expose a bit of unbrokenoff pin. Brush that bit, Flux it, Tin it, and solder to it a lenght of leg. I borrow my legs from the extra bits from standard value resistors and get to use the resistors as well!
get your self a key cloning device just in case you need to make stuff like that again.
Their is a way to read that chip. I have done also dubbed many others.
A good reason to not try to carelessly open the case with a screwdriver to replace the battery.

That is fantastic :)
reminds me of when i broke my playstation 1 20 years ago and i soldered tiny wires on a chip :)
