Make money online: YES

A locksmith business can be quite remote-friendly as much of the work can be done on-site at clients' locations. However, there may be occasional in-person requirements for certain tasks such as key duplication or lock installations. Online discussions on platforms like Reddit and Twitter suggest that many locksmiths are able to operate their businesses successfully from various locations. The level of remote-friendliness may depend on your location, access to clients, and time zones. It's essential to have the necessary equipment such as key-making machines and tools. Setup costs for a locksmith business can range from $1,000 to $5,000. With efficient marketing strategies and client acquisition, it's possible to start making a profit within 2 weeks. One potential red flag is the need for proper licensing and certification, which can vary by state or country.
