Maybe, but it would be huge. Most key fobs I’ve seen don’t need mounting screws either. I’m not sure about the battery holder, but any buttons on the other side would likely run through the pcb. I don’t think contact solder would be strong enough for repeated use. There would also be traces somewhere that come from the other side to the controller.
I don’t see any merging traces or other aspects of it that don’t make sense when looking at the board holistically, so I don’t think it’s AI. Edit: another commenter pointed out two “pin 1” marks on the biggest chip, so never mind, it’s AI. Fuck.
With two microchips with that many pins (maybe a 4+ layer PCB?), it looks too complicated to be a key fob. It also has what looks like a 5-pin header for programming.
