Years of Experience

For more than a decade, Keystone Lock & Safe has been providing prompt, professional and courteous service to all of our customers.

We can provide all of our customers with a full range of access control options, locksmith services, low voltage security services, security cameras, and safe and vault services– all utilizing the latest technologies.

We offer house accounts to service providers and property management companies for emergency service in the field, fresh installations, repairs and ongoing preventative maintenance as well as for quick counter pick-ups for key duplication and hardware orders.

Each truck in our fleet of service trucks is fully stocked, so in most cases, one trip is all it takes to get your problem fixed and get you back to business.

Centrally located in Deer Park, NY, we provide Nassau and Suffolk Counties with trained, on-staff , security, lock and safe experts—no subcontractors.
