Learn the Trade

Before you can get a license to open your business, you’ll have to prove you know the industry. One way is to learn on the job by working for a licensed professional locksmith as an apprentice. The state of Texas, for example, allows locksmiths working in the field for a couple of years as an apprentice to apply for their own licenses. Another option is to attend a school authorized by your state to teach locksmithing.

Apply for a License

Purchase Necessary Equipment

Build Your Clientele
