Colorado does NOT have a specific Locksmith license. This puts the onus on the public to choose carefully.  A business license is required with the Colorado Secretary of State. Businesses also may be required to have a license in their base town or city of operation; as well as sales tax licenses. Many dispatching companies use false local sounding names and addresses, are uninsured, and their "subcontractors" carry no required licenses, insurance nor identification. Who do YOU trust?

We are the Louisville locksmith you can trust

Your security and safety are incredibly important. Carefully choose who you entrust this information with. City Lock is your Boulder Locksmith;  fully insured and properly licensed with the City of Boulder, State of Colorado and IRS. We do NOT use aliases to confuse the public.
