Lock is less than 2 yrs old if that. Like I said Tech guy replaced the card like a year ago if that. Thing is on top of everything else the tech guy put a lot of redundancy in my system, a lot of stuff I knew I didn’t need (because my other house was C4). Little disappointed with the guy to be honest, and trust is going out the window because of that. On top of that and my compromised immune system, I don’t want him here.
