The three large roundish exposed copper structures toward the edge of the top of the PCB are the contact areas; pressing the button shorts the traces in these structures together. I suspect shorting one of these structures is enough to trigger the button, but I’m not sure on this point.

I wanted to remove the button and repurpose this with a reed-switch by my front door to trigger the lights on arrival.

I haven’t really tried.

Did you ever make any progress in repurposing these?

I connected using Linux (BlueZ 4.101), after placing the button in pairing mode by pressing it until it starts glowing orange. Here’s what hcitool knows about the button:
