Alarm died, was notified two days later. Was told battery died, I replaced and still would not work. Called them and they told me to press the star button twice, nothing happened, they said that was all they could do. If I wanted it fixed, I would have to pay $150 just for a tech to show up, plus the cost of repairs. Was told it would be “hundreds of dollars”. Tried pressing different combinations of buttons and accidentally set off alarm. They called, told them the situation and was told to press the star button. I’m done with this brutal company.
