Video Pro Doorbell with Protection Plus Warranty: How to invoke

I needed to reset my network SSID and password today because I changed my WiFi network. It was very, very difficult to perform a reset on my Video Pro Doorbell. It appeared dead. After trying to use the side button to put it in setup mode to no avail, I tried several hard resets (15 seconds) and could not get it into setup mode. Finally it did, but I fear the device is very close to failing completely. This is a crucial piece of my home security network. How do I get this replaced?
