Mercedes Benz Fob Repair - Turns on Vehicle but all buttons do not work

[@crazyphil7782]

As a tip for your future repairs, those circular pads are SMD test points. They are used to debug the circuit and always carry an important signal. You didn’t need to restore a corroded test point for the FOB to operate. Nice work

[@lee3521]

I was screaming at you through the monitor about that trace! I can't believe you didn't hear me! LOL Great job.

[@abdorb6152]

yeah hhh lol if he see it , he will not need the donor board

[@gorjy9610]

same here. But this prove that distraction can be a good thing sometimes, is somebody didn't call him maybe he would still chase that testpoint :)

Great fix as always, btw my purchase of those tweezers and angled 9m nozzle for the Quick came in almost next day. Super pleased with both, tweezers are fantastic no pressure / issues with small caps / res's when assembling boards. To any makers if you have not gotten your tweezers yet ( Mechanic) I highly recommend you do right away as these made working with msop 10 and qfn parts super easy to work with.

All those circular pads are for ICT ( In Circuit Test) at the factory, so doesn`t matter if they are all broken, the key should function anyway!

You can shine a light through the board the see the traces on the other side. Try it!

As you said in earlier videos that you achieved your hand stability by resting it in the table. I couldn't do that. Idk why. Can you tell more about how?. And also, i am inspired by your work. Great work. ❤️ from India.

Newbie question from a hobbiest. What's the point of 0 ohm smd resistors? I would expect it to be cheaper to just keep the trace going?

[@TomStorey96]

You can use them to jump over other traces, or quite often they are used to enable and disable various options or features, or even as configuration settings. In the latter two cases they may be referred to as "straps".

[@markjohnson1207]

At 3:27 in the video you can see a break in the trace line above the pad you before you started to scrape at the pad, isn't that the same issue you fixed with the wire?

[@Thesusoperator]

Awesome!

[@pupil2720]

usually the bigger round pads are test pads used by quality control at the factory so they aren't vital to the functionality of the board.

[@pfiltz]

What I keep wondering is how a trace just bust out in the middle. That Mother board is in a plastic case. There were no moving parts associated with the trace, from what I can tell, so why did the trace go bad in the middle like that? Thoughts?

[@bobbaxter952]

I bought a batch of merc new keys and the first two i used they started the car and they put put a 433mhz signal!!(Eu model) hiwever the fobs didn't open/lock the doors. The led,s didn't light up on the remotes!Is this repairable?

You have many neat tools. Get a soldering iron smaller than a baseball bat and your soldering wouldn't look so crappy.

[@aliasgerzakir]

Just and idea, you could have inserted your thin jumper wire through the hole and it would have come out the other side of the board to know where the trace was going.

Not if the via is tented, i.e. filled with solder mask. Looked like they all were to me.

Tbh the default was directly visible on this one, because the mask wasn't in the same color, and this generally show a problem, also if you put a bright light below the PCB (for this type of PCB you see clearly the trace) also the rules is not solder a wire if not needed because this fragilise the pad, and it was totally possible to the multimeter without soldering a wire ^^.
