"ADT is the best company to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

"When I called around for quotes and to make the appointment, AA Key & Lock had clear upfront pricing and answered all of my questions. They had several options to find a convenient time for the service. They were able to rekey front and back door and install deadbolt on basement door for a newly purchased home in about an hour."

"Jeremy was punctual and professional. The appointment was easy to make with fast scheduling. I received an in-depth presentation and walk through of my home. He was very responsive to my questions and family's needs. There was no pressure to buy or add equipment I did not want or need. My new system was installed two days later. Larry the technical adviser was amazing. He was knowledgeable and friendly. He installed my system with no problems. He took the time to give us a lesson on how to use the app and new system. A few days later I had a question and he responded right away. I loved the system so much, that I referred my mother. Her system was installed a week later. I feel so protected knowing my family is safe using 1st Security Alarm company. I have the confidence of knowing that I can upgrade my system at any time. I can not thank Jeremy and Larry enough."
