I would, without a doubt, recommend your services! There is no other locksmith that comes close…. and I would never use or recommend anyone else!

My gratitude and sincere appreciation!

DLS has never failed me in any request for solution I have presented. Always on time, always within budget. If I need help figuring out an access solution, they find the answer. If a project I am working on has a locksmith that cannot do the work or procure the materials on time, they figure out the solution. Peace of mind is the best feeling I can get from any vendor and this team gives me exactly that!
