Hy guys, i have this Audi smart key with a touch screen not working, the key has a 450 mA battery inside that looks ok on the multimeter, but when connecting the usb c on the board there is no power consumption, no current going to the board. Has anyone worked on these before?

What Audi and year is this from? My guess is the the IC in the 3rd pic, bottom left. See if you got juice going in to it but not coming out.
All I can say is: if the Audi has an encrypted BCM2, you need to do a bench flash and an AKL and virgin keys to replace them if you can't get it going.

It's just an adaption it's not the original key, they sell it on aliexpress, and you can add the motherboard from the original key to this one and transform it into a "smart key" with touchscreen... I've returned it because the cost of it it's the same with the time spent on it to figure it out.
