Long story short – I had painters put a new coat on the exterior of my house. Afterwards my doorbell no longer worked…given the only thing that changed was on the outside I sought to replace / fix the button itself. I found a great online set of videos at Expert Village that saved me enough money to pay for my starbucks habit for atleast 2 weeks.
The trick I was looking for was – how do I remove the doorbell… I knew there were connectors underneath but couldn’t figure that part out. Simple enough – you take razor or other equally thin (I used my leatherman) piece of metal and place it between the cover and wall mount. Then use it to pop off one side and work it out that way. Here is the video link for convenience.
Good luck to those maintaining their houses!
