Locksmithing & Security Technology

Our unique Locksmithing & Security Technology (LK) program allows students to jump-start a locksmithing career and quickly earn a return on their educational investment. Unlike online courses, in the hands-on, full-time, nine-month program students learn from a master locksmith in small classes. Most students work in the field while enrolled.

You’ll learn locksmithing through a combination of classroom theory, lectures, demonstrations, and hands-on benchwork and fieldwork. We take a practical approach to your education, which many professional organizations appreciate. Classes meet five days a week in the mornings, so students can work part-time while learning the trade.

The program space includes individual benches for each student, a room for instruction and demonstration, and all the major equipment and tools you would find in a locksmithing shop. We also have state-of-the-art computer equipment and a resource library.

The program gives students a firm grasp of the fundamentals and allows them to do high-quality work after graduating. You’ll graduate with the ability to service and repair all types of residential and commercial door-locking devices. You’ll also be familiar with electronic and mechanical access control systems.

Note: Due to privacy concerns, on-time completion rates are withheld when fewer than ten students in a graduating class received Title IV, or "federal," financial aid during their enrollment at NBSS. Because our programs are small, this information may be withheld or appear low in any given year.

Typical earnings rates are based on the earnings of our graduates as reported to the U.S. Department of Education (DOE) by the Social Security Administration (SSA), and therefore may not be an accurate reflection of potential earnings in a given field.
