Check Out What Our Students Have To Say!

It was a great class. Hands on environment that was not intimidating and Tim worked directly with each student, whether they had experience or was new to locksmithing. My wife will be attending the next class since she plans to help out in the locksmithing business. I highly recommend the class to anyone who wants to learn the locksmith and electronic security business. He is my go-to mentor!
Alex K.
I attended for my 25E class. I only signed up here because he was the ONLY one to respond to my email. His class was 100% worth the hour drive. It was very hands on, and he always stopped to answer questions. His experience and skill shows through in every aspect of his teaching style. If you are looking for a class, Tim is the teacher you want.
Virgil D.
A great DCJS course! A lot of hands-on experience and training, with a comprehensive workbook. I can't think of a reason to go back to another training school again.
David N.
