Lexington Alarm Systems first opened its doors in 19XX right in Lexington. Although we have moved around a bit over the long 45 years, we are still very pleased to serve such a historical and beautiful community right in our backyard!

With a population of 32,000 people, including over 11,000 households, Lexington Alarm Systems strives to provide exceptional residential security to these houses and families.

One of the biggest perks with going with Lexington Alarm Systems, is you are going with a local company with a name you can trust. Our UL Listed, FM Approved Monitoring Center is located right on the North Shore in Lynn MA, and you work with faces and names you are familiar with.
