State Locksmith Licensed




Mystic Fire Department

I am a customer with AA Lock and Key and would like to share some experiences that I have with the members and services from AA Lock and key. My most recent experience was having Dave come to the Fire Station and Plan a new electronically programmable door controller that allows me to program different codes for different users which has a timer attached and times out after the set time. Confused yet? Don't worry, Dave and his staff will respond quickly to your needs and efficiently install whatever it is you wish to accomplish. And by way of "Service with a smile"?

Dave and his technicians bide by that saying, even with the toughest jobs, Dave will look over at you and say "We will get this done"! The job that Dave did looks like the door came with all of the equipment that he installed, A great job.

Dave/Debbie, I wanted to wish you a Happy New Year and Thank you for another year of exemplary service to our plant. Your rapid response each and every time we called you combined with your knowledge and experience of all our systems allowed us to complete another year with no overtime charged for security of unlocked or inoperable doors due to mechanical or electronics (in the case of our security swipe stations). We anticipate many more years of excellent service from our door security systems and door entry controls under your service. Thank You."      Al Seals , Electronic Technician

Dave & Debbie,

I would like to thank AA Lock & Key for the prompt service they have provided to our office the past few years. The first time was an emergency when a safe broke in the locked position. You responded quickly and saved us from days of downtime by drilling the safe open so we could move the contents to another safe while you repaired the broken one and replaced the lock with a new electronic lock. We then had you replace more locks before they failed and hope to eventually have you replace all of them. You also responded quickly when we recently had trouble with a safe lock that was becoming a problem and you were able to repair it before it failed. We really appreciate your efforts and look forward to a continuing relationship.
