Maryland Locksmith Licensing and Legal Requirements are governed by the Maryland Locksmiths Act (Title 12.5, Business Regulation Article), which requires every locksmith business operating in the state to hold a valid state-issued license. This page summarizes the current rules, fees, penalties, and consumer-protection provisions that apply to locksmith services in the state.

Maryland Locksmith Licensing and Legal Requirements: Is a License Required?

Yes. Maryland is one of a small number of U.S. states that actively requires locksmith businesses to be licensed at the state level. The governing statute, Title 12.5 of the Business Regulation Article, Annotated Code of Maryland, also known as the “Maryland Locksmiths Act,” sets forth the requirements for the licensing and regulation of businesses that provide locksmith services in the state. The Act has been in effect since July 1, 2009, when it was enacted to protect consumers from unlicensed operators and pricing scams.

Under this law, every business entity that provides locksmith services for compensation must hold a license — this includes corporations, partnerships, limited liability companies, limited liability partnerships, and sole proprietors. The definition of “provide locksmith services” covers repairing, rebuilding, rekeying, repinning, recombinating, adjusting, or installing mechanical, electrical, or electromechanical locking devices, safes, vaults, or safe deposit boxes, as well as opening such devices by non-standard means.

An important distinction in the Maryland framework is that the license is issued to the business, not to individual technicians. Employees who perform hands-on locksmith work do not need their own separate license. However, every employee who provides locksmith services must be formally registered under the employer’s license and must undergo a criminal background check. Non-locksmith employees (office staff, drivers who do not perform locksmith work, etc.) are not bound by this requirement.

Maryland does not require a written exam to obtain a locksmith license. No minimum experience, apprenticeship hours, or formal training are mandated by the state, though voluntary certification through organizations such as the Associated Locksmiths of America (ALOA) is available.

Current Issuing Authority for Maryland Locksmith Licensing and Legal Requirements

The agency responsible for administering locksmith licenses in the state is the Maryland Department of Labor, operating through its Division of Occupational and Professional Licensing. Within that division, the day-to-day work is handled by the Maryland Locksmith Licensing Program.

The program’s offices are located at 1100 N. Eutaw Street, Room 121, Baltimore, MD 21201, and they serve applicants by email, telephone (410-230-6159), and limited in-person appointments scheduled through the Department’s Central Scheduling System. Walk-in assistance is not available. The program also maintains an online licensing database that consumers and law-enforcement agencies can use to verify whether a particular locksmith business is licensed or whether a specific employee is registered under that license.

Implementing regulations are found in the Code of Maryland Regulations (COMAR) Title 09.40.

License Classes, Renewal, Insurance, and Background Checks

License Structure

Maryland issues a single class of locksmith license, granted to the business entity. The business must be registered and in good standing with the Maryland Department of Assessments and Taxation before it can apply. A license is tied to a specific fixed business address — a motor vehicle, hotel room, or P.O. box does not qualify as a fixed business address under the Act.

Application Requirements

To apply for an original locksmith license, the business owner or designated official must:

• Be at least 18 years of age.
• Submit a completed application with a passport-sized photograph taken within the previous six months.
• Provide a copy of the business’s registration with the Maryland Department of Assessments and Taxation (corporations must include Articles of Incorporation and a Certificate of Good Standing).
• Submit to a full federal and state criminal history records check via the Criminal Justice Information System Central Repository (CJIS), including fingerprinting at an approved facility.
• Provide a certificate of general liability insurance with minimum coverage of $300,000, naming the State of Maryland Locksmith Licensing Program as the certificate holder.
• Maintain a fixed business address within or outside the state.

The Act empowers the Department to deny a license to any applicant convicted of a felony or a misdemeanor directly related to the fitness and qualification of the applicant to provide locksmith services. Disclosure of a conviction is not an automatic bar to licensure; each case is reviewed individually.

Fees

The license fee is $225 (non-refundable), payable only after the application has been approved. The renewal fee is also $225. Additional fees include $50 for a business name change and $50 to add an employee. Fingerprinting fees are separate and paid directly to the fingerprinting facility.

Renewal

The locksmith license is valid for a two-year licensing period and must be renewed before it expires. Renewal applications are mailed approximately 60 days before expiration. To renew, a business must submit a completed renewal application, a current Registration of Locksmith Technician Form listing all covered employees, a current certificate of liability insurance, and the renewal fee. The business must remain in good standing with the Department of Assessments and Taxation at the time of renewal.

Employee Registration

Each employee who provides locksmith services must be registered by the employer through a Report of Employee form. The employee must also be fingerprinted and pass a federal and state criminal background check through CJIS. Licensed locksmith businesses are required to issue durable photo identification cards to every registered employee; these cards must include the employee’s current photograph, the business’s license number, and the license expiration date.

Bonding

Maryland’s locksmith law does not require a surety bond. The insurance requirement (general liability of at least $300,000) serves as the primary financial-protection mechanism.

Exam Requirement

There is no state-administered exam required for a locksmith license in this jurisdiction. No prior locksmithing experience is required either, though the licensing requirements above must be fully satisfied.

Penalties for Unlicensed Operation Under Maryland Locksmith Licensing and Legal Requirements

Maryland treats unlicensed locksmithing as a criminal offense. Under § 12.5-505 of the Business Regulation Article, a person may not act as, offer to act as, hold oneself out as, or impersonate a locksmith in the state unless the person is a licensee or an employee of a licensee. Violations carry the following consequences:

• First conviction: Misdemeanor, with a fine of up to $1,000.
• Second or subsequent conviction: Misdemeanor, with a fine of up to $5,000.

In addition to criminal penalties, § 12.5-506 authorizes the Secretary of the Department of Labor to bring a civil administrative action against any person who violates the licensing requirement. After a hearing, the Secretary may order the person to cease and desist from unlawful practice and may impose a civil penalty of up to $100 for each day of unlawful practice.

Furthermore, under § 12.5-501, a licensed locksmith or employee may not knowingly use or permit the use of their skills, tools, or facilities to aid or abet an unlicensed locksmith in any activity for which a license is required.

City and Local Variations

Maryland Locksmith Licensing and Legal Requirements apply uniformly across the state. Unlike some other states, Maryland does not have a patchwork of city- or county-level locksmith licensing ordinances that add separate layers of regulation. The state-level license issued by the Department of Labor is the sole locksmith-specific credential required.

That said, locksmiths — like any business — must still comply with general local business-registration and tax requirements in the counties and municipalities where they operate. For example, Montgomery County’s Office of Consumer Protection actively advises consumers to verify a locksmith’s state license before hiring, reinforcing the state program at the local level. Baltimore City, Prince George’s County, and other jurisdictions similarly rely on the state licensing framework rather than maintaining their own locksmith-specific permits.

Companies like Low Rate Locksmith that serve customers across multiple Maryland jurisdictions hold the single state-issued license and comply with any applicable local business tax or registration requirements in the areas they serve.

Documentation for Locksmith Service Calls

The Maryland Locksmiths Act imposes specific record-keeping obligations on licensed locksmith businesses. Under § 12.5-301, every licensed locksmith must include certain information on each invoice or receipt for services, including the address where services were provided and the quoted cost of the service. These records serve both consumer-protection and law-enforcement purposes.

Under § 12.5-303, a licensed locksmith must provide a copy of any invoice or receipt to a local law enforcement unit or to the Department of Labor upon request. Copies must be delivered or mailed within five business days of the request, or transmitted electronically within two business days. Locksmith businesses are required to retain service records for at least three years from the date of service.

These documentation requirements mean that consumers in Maryland should always receive a written invoice showing the locksmith’s license number, the service address, and the cost. If a service provider cannot produce a license number or refuses to provide a written receipt, that is a significant red flag. Consumers can verify any locksmith’s license status through the Department of Labor’s online licensing database or by calling 410-230-6159.

Exemptions From Maryland Locksmith Licensing and Legal Requirements

Not every activity involving locks requires a license in this jurisdiction. The Act provides specific exemptions, including:

• Key duplication or key-blank acquisition (standalone key cutting).
• Emergency lock-opening by police, fire departments, or government agencies acting in their official line of duty.
• Replacing a removable or interchangeable core designed by the manufacturer to be changed by the end user with a key.
• Lock installation, repair, or rebuilding performed by the lock manufacturer or its authorized agent.
• Automotive lock work performed by an automotive repair facility, the vehicle manufacturer, or its agent.
• Lock installation by building-trades personnel working on projects that require a building permit.
• Lock installation or replacement by a retailer as part of a retail sale.
• Bona fide sales demonstrations to locksmiths or locksmith suppliers by unlicensed sales representatives.

These exemptions are narrowly defined. Any person or business that falls outside these categories and provides locksmith services for compensation must hold a valid license.

Consumer Tips

Because Maryland Locksmith Licensing and Legal Requirements are robust compared to many other states, consumers in the state have meaningful tools to protect themselves:

• Verify the license. Before hiring any locksmith, search the Department of Labor’s online database or call 410-230-6159 to confirm the business holds a current license.
• Ask for employee ID. Every registered locksmith technician must carry a photo identification card issued by their employer that shows the business’s license number and expiration date.
• Demand a written invoice. State law requires every service call to produce an invoice with the license number, service address, and quoted cost.
• Check the business address. A legitimate licensed locksmith must maintain a fixed business address. Mobile-only operations that lack a verifiable location may not be properly licensed.

Low Rate Locksmith encourages all consumers to exercise these verification steps to ensure they are working with a properly licensed and insured locksmith business.
