Did not have to worry about the thing. Lenny managed all the aspects and some more. I could concentrate on my business why Lenny made sure it is protected. Thank you!

Years of Dependability

We’ve been customers of Keystone Alarms for years. Lenny, Jennifer and Mike always have our best interests at heart. They’re thorough, reliable and so easy to work with. Customer Service like this isn’t easy to come by these days, but I can ALWAYS count on Keystone to take care of our every security need.

Excellent service and lovely people

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.
