I haven't been able to find a how-to guide/video to replace the button so I recorded a walk-through. Apologies for the choppy editing, and I'm by no means an electronics expert so please only use this as a guide!
We are currently investigating this issue. In the meantime, we advise you not to replace your doorbell button. Altering the button may damage the motion sensor behind the button and may result in a defective product and/or void the warranty. We will update this thread on any new findings from the team. Thank you!
