Danbury’s most respected locksmith company

SDS is Danbury’s most trusted and professional locksmith company in the local area. We aim to empower our customers through giving them knowledge about the security of their home, rather than only selling products and services.

We solve problems and provide clear explanations about the lock solutions we provide. We have a method to suit almost any budget and security concern, and will only leave your property once you have safely regained entry to your property.

Our Danbury based technicians are available to help whether you find yourself locked out of your home or business, moving to a new house or business premises, or if you want to review and upgrade your security.

Using a consultative approach puts you in the know about
the lock mechanisms available to you. You can then
make an informed decision based on the knowledge
we pass onto you, further securing your property.

Each of our locksmiths have been carefully chosen
and background checked and must adhere to our
strict ethical guidelines. Placing professionalism first
means we have developed a reputation in Danbury
as one of the most detailed and thorough locksmith
services around.
