Excellent Service and Customer Service

April 25, 2025

I needed my fire alarm system upgrade and brought up to code. Keystone Alarms came in and got the job done right the first time, and the cost was competitive with other companies. Every time I call for any help, they immediately answer. Excellent company!

Heard chirping and going crazy

April 25, 2025

I have been a customer for 19 years. When ever I needed Keystone Protective always available. I heard chirping and couldn’t figure it out. It was coming from my attic. Operator had me take pictures and I sent them by phone. It was an easy fix and no serious issue. No service call was needed. The operator spent time on the phone with me and was very patient. Very kind and explained what to do. I’m very grateful for her patience and kindness. Not everything is about money.

God Bless you Keytone Protective for helping me. I have been with you for 19 years.

👍⭐️⭐️⭐️⭐️⭐️

Always a pleasure to work with Len and his team.

Was looking for a practical solution to eliminate landline alarm hook up, and Len had the answer I was hoping for.

To the Rescue

December 12, 2020

My wife researched alarm companies on the internet and thought Keystone was a good fit because they didn’t appear to be a nation wide company who would lose us in their large portfolio. She was right.

We called after our system went down following some work done at our house. Jen was terrific! She was able to fit us in the following morning.

Joe and Scott assessed the damage and explained everything to us in an understandable way. They did the work professionally and cleaned up to leave a spotless work area.

We hope to be long time customers.

Feeling safe!!

Lenny and the entire team we’re diligent and efficient on creating the best alarm system for my home . They were professional and courteous and kind throughout the entire installation. They spent time making sure it was working properly. It’s really nice to know that you can call or email them and you get to connect personally with a company that has your back!

I had total communication and comfort when Lenny and his team worked together to create the best security system. He carefully walked around my home and created the best security plan for me and my family and dog:)! They spent many hours installing the system with a team that was professional and pleasant and wore masks! They were in communication with me following up on installation and when all the equipment would arrive.,( thank you Jennifer!)

I feel safe and secure! Thank you!

Len and Keystone was recommended by a neighbor. Len came out to the house and made great practical recommendations to suit my needs without selling me the farm. Made a few adjustments after the onsite visit without any hassle. Jen in the office was helpful and friendly too. Looking forward to the new system.

Len and his staff respond almost instantly to inquiries. I’ve had no problem with the system since it was installed 4 years ago. Neighbor has DIY system that always has issues. Tech just installed additional sensors. He was friendly, attentive and professional. Call center responds immediately when alarm activated.
