See what others are saying about us

Janis and I are extremely satisfied with Keystone Alarm.  We would recommend it to anyone.  The installation was professional, we never had a problem with the system, our rates were raised only once in the 10 years (which was only a few dollars), and the response we receive accidentally tripping the system is immediate and consistent.  Keystone is an A+.     W.D. – Red Lion, PA


When we first talked to Keystone Alarm, we thought we were just buying a service; instead, we made new friends.  When we needed to call Keystone Alarm in a moment of concern, instead of just having to hope we could get some measure of assistance from an impersonal service company, we just called an old friend.   L.R. – McSherrystown,  PA


We contacted Keystone Alarm for an estimate on an alarm for our new home.  As soon as we met them, we felt assured they cared more about us and what type of system would best suit our needs versus the “one size fits all” mentality we’d encountered with other companies.  Their staff was extremely knowledgeable and professional, providing us with a cost effective system and smooth installation.  In addition, the monitoring service is incredibly efficient, calling literally within seconds whenever we have an alarm.  We highly recommend them to anyone considering the investment of an alarm system for either home or business.   M.T. – Littlestown PA

I have been a customer of Keystone Alarm Company for years, and I choose to do business with them for a few reasons.  First, the people provide immediate attention to

my questions and concerns.  They run the company with high character and good values.  Second, they provide and fully understand the latest in technology for home/business protection.  Finally, they remain cost competitive.  I appreciate what they do for my company.

Kevin and Anita are very nice people to do business with.  Their customer service is outstanding.  The alarm system works great and I would recommend to everyone to call Keystone Alarm first !!!  Jim Lenig, Owner-Lenig’s Coin & Jewelry-New Oxford, PA


Keystone Alarm installed a security system with cameras for our church last year.  We have been very satisfied with their service and they have always been very helpful whenever we called with questions.  Kevin and Anita took the time to explain all we needed to know about the system.  We have not had any issues or concerns with our system since it was installed.  We would highly recommend Keystone Alarm to anyone.

We were referred to Keystone Alarm for their video surveillance services after major problems with a new system we had purchased.  Kevin, Anita and their staff identified the issues with our system and made recommendations to solve our problem.  We had them install a new system in each of our businesses and have been really pleased with our equipment, the price and the service.  The service has extended for years after the sale and we just can’t say enough good things about them.

Barry & Ronda Zeigler-Owners of the Franklin House Tavern & Midway Tavern-Hanover, PA


We had one of the national companies handle our security and fire alarm systems for twenty years.  When the time came to replace those systems, we invited six vendors to submit proposals and we chose Keystone Alarm.  The personalized service and attention to detail is far superior to anything we experienced with our previous vendor and all at a fair price.  Our overall relationship as a new customer of Keystone Alarm has been very positive.
