Mystic Aquarium

"AA Lock and Key has been a valued partner in Mystic Aquarium's Safety & Security programs for over 17 years.


Their experienced locksmiths have helped recommend, procure, and service access control devices for several diverse applications during my tenure with the Aquarium. It is truly a pleasure to know each of their team members on a first name basis, whether I am visiting the shop, or when someone performs field maintenance.


Many thanks to everyone at AA Lock and Key for their consistently high level of customer service!"

-Nathan S. Fague, MS

Director of Safety & Security, Mystic Aquarium



"First time customer and extremely happy we called AA Lock & Key.


During a door repair we encountered a broken (~60 year-old) Mortise lock. There are not many replacement Mortise locks or the hardware to go with it.  We called the shop and sent Dave some pictures of our predicament. He gave us a couple of options, one being rebuilding/repairing the original Mortise lock.


Dan repaired the old Mortise Lock and reinstalled the lock and hardware on the repaired door. The lock and door hardware are working perfectly, probably have another 60 years of life.


Definitely going to be a repeat customer with AA lock & Key.


Excellent service, professional, arrives on time and they know their business."

- Dennis R. Mystic, CT



“We had to contact AA Lock and Key for help in unlocking our Gun Safe at our Baltic residence. The receptionist was very helpful and we were pleased to find out that they could schedule an appointment for the same day. The office called to confirm the appointment and the technician arrived exactly on time. He was very efficient and polite. He explained the situation we had in detail and was able to get the safe in a working condition for us to be able to unlock and lock it. I am sure if we were to have another lock issue we will most definitely contact AA Lock & Key.”

- Catherine & Dave S. Baltic, CT



Mystic Fire Department

"I am a customer with AA Lock & Key Inc. of Ledyard, CT, 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."

- Tony Manfredi

Assistant Fire Chief / Deputy Fire Marshal, Mystic Fire Department

“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."

They're always prompt in responding to our needs with the same friendly, reliable, and accommodating service."

"I work for a company that owns 24 gas station / convenience stores and 6 Wings restaurants, and I've been doing business with Dave for 20 years.


He has always amazed me with his knowledge and he has always been able to help me with whatever I need. I still remember Dave cutting me a skeleton key for my house. Thanks guys for all you do."
