We have been using Keystone for a few years, and they have been responsive. We are in the process of moving into a new office and look forward to Keystone setting us up with a state of the art system.

I needed someone to come out quick and install a fire alarm. They worked with me and came out the next day! They also called me when they were on there way which was great!

My mom was feeling sick and forgot she was cooking soup. Her pot melted and house filled with smoke. The alarm Lenny Weiner installed alerted your company and they called fire dept. and saved her life. We are forever grateful for your service and company!

Lenny and Jennifer were delightful and patient in helping us choose the components in our system and instructive in getting a system that fits our need. Mike was delightful and professional installing the system–very thorough, neat and efficient in installing features that we requested which are not routinely used. We have had several alarms in various houses over the years. The Keystone team was by far the best we have dealt with in all of those experiences.
