What to Ask

Verifying a Commercial Locksmith in San Carlos

Commercial locksmith work in San Carlos carries higher stakes than residential. A faulty access control installation or master key system design flaw can compromise an entire facility. Verify these items before signing a contract:

  • BSIS company license: The locksmith company must hold a BSIS license. Individual technicians on larger commercial jobs should also have their own licenses. Verify both at bsis.ca.gov.
  • Commercial locksmith experience: Ask specifically how many commercial access control projects they have completed in San Mateo County. Residential-focused locksmiths may not have the right tools or certification for multi-door access systems.
  • Master key design credentials: Master key system design is a specialized skill. Ask if the locksmith holds an ALOA (Associated Locksmiths of America) certification or equivalent.
  • Manufacturer authorization: For major brands (HID, Lenel, Software House), ask if the installer is an authorized dealer or integrator.
  • Written scope of work: Any commercial project above $500 should come with a written scope including hardware brands, labor breakdown, and warranty terms.
San Carlos Industrial Road context: Many Industrial Road tech and biotech companies have sensitive facility requirements including SCIF-adjacent spaces, server room access, and visitor management systems. A commercial locksmith experienced with these environments is distinct from a general residential provider.
