Locksmith license in Maryland
The short answer
Statewide licenseYes. Maryland licenses locksmith businesses through the Department of Labor under the Maryland Locksmiths Act. The license is for the business, and every employee needs a fingerprint background check before starting work.
- Who needs it
- The business (sole proprietor, partnership, corporation or LLC)
- Employees aren't licensed themselves, but each one is reported to the state and background-checked
- What the source says it takes
- State and FBI criminal history check with fingerprints for the owner and every employee, before they start work
- General liability insurance of at least $300,000
- A fixed business address
- A photo ID card for each employee showing the license number
- Invoices and receipts kept for 3 years and shown to police or the Department on request
- The license lasts 2 years
What to do in Maryland
Apply with Maryland Department of Labor before you take paid work, and keep the license current. The agency's own page has the forms, the fees and the latest rules, so start there rather than with a third-party summary, this one included.
Once you have a number, put it where customers and Google can see it: on invoices, estimates, the van and your Google Business Profile. Some customers ask for it, and it shows you're a real local shop.
Local rules
We didn't find a city or county locksmith license in Maryland. Local rules change more often than state law, so ask your city or county clerk.
Every state: ID and proof on every lockout
Whatever the license rules, check a photo ID and proof that the caller lives there or owns the car before you open anything, and keep a record of it. Our lockout authorization form gives you a signed record for the file.
