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.
@@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)

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
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!
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
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.
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.
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
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.
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.
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!
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 admire your work in my eyes you are a virtuoso. I'm in my mid-40s and would take an apprenticeship with you anytime. Keep it up and continue to enlighten us with your work´
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.
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.
I did something like this on a Texas Instruments calculator once. It required the use of a microscope. Once the jumper was soldered, I very gently cleaned the area, dried it with light puffs of canned air, and then put some epoxy cement over it for mechanical support and protection. You should consider doing that, too. You were very fortunate that the chip case was plastic and not ceramic like the kind used in defense electronics.
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 and big boss are awesome i watch you everyday and learn new stuff , i am disabled and work on a folding bench with a vice attached to it , it helps me hold conponents in place , see i had a brain heammorrage at 25 etc so makes movement very hard indeed , i wish i could afford that flux etc but being disabled really sucks the meat off of you. good posting videos aas well. regards .
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!
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...
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?
Nice repair. You made it look easy. The missing component looked like a capacitor. You could have measured its value and replaced it with a new part instead of needing to take one off a donor board. It would allow you to replace the missing part on another board in the future.
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?

Shocking to think a single small wire from a lump of sand can cost £500 to replace - sadly a cost all born out of human greed as if people didn't steal cars, break into houses etc - life would be so much cheaper and better. Brilliant work SIr and glad to see even after all these years, the reward of the smallest success still brings a smile to your face and rightly so. Keep on being you.
IMO Greed and poverty are the biggest cause of crime. Stealing cars is usually a result of the poverty end of the equation. I don't see many car theives living in mansions but I see lots of financial criminals living in them. It's never black and white but that is my opinion.
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.
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.
Actually you can leave the chip in place on the PCB, and grind away the plastic until it exposes the lead-wire stub. Solder a small 4-6mm long solid copper wire to the PCB trace, and then bend&trim the other end of the wire onto the chips' stub, and solder that. And Voila: All pins are now reconnected. (I only recommend leaded solder for making this easy repair)
How did that happen?? Were they using the fob with no cover?? Is this FOB made on the end of the key?? I have saw late model Mercedes that have faulty Steering Column control modules causing the key to not be able to be rotated, but those were FOBs on the end of the key. Customers will state that sometimes they can yank real hard on the steering wheel while its locked and get the key to turn. But looking at that key fob that almost certainly has something to do with their problem. They make scan tools that are specifically made for programming keys. My Snap On scanner will do some, but if it couldnt we used to call a locksmith who had a key programmer. You dont really need to read the programming, just learn the new key to the car. Before I left the auto repair industry my old boss bought a mid level key programmer for around $500. We were experiencing alot of key programming issues, lost keys, defective keys, customers who bought cars with only 1 key who wanted extras. Im assuming this fixed their problem??
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.
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
I've done this in the past and it's doable but be aware that the chip pin only goes about 1 mm deep (depending on the type of chip and topology) so don't grind too much off. Besides that, you can program a new NEC chip even if your merc doesn't have any keys at all ;-)
