Legendary inventor Klaus W. (Nick) Gartner passed away on September 5th 2023. Nick got his start in the high security safe lock industry in the early 1970’s when Harry C. Miller – then president of Sargent & Greenleaf – challenged him to design a new manipulation proof combination lock. In the ensuing decades, with more than eighty patents to his name, Nick introduced so many innovations to the security industry that it’s difficult to find a safe lock without a feature derived (or copied) from one of his original designs. 

Nick has been my teacher and mentor in the lock industry for more than thirty years. For the last fifteen years, I have had the privilege to share in the development of the NL Lock brand, his final brainchild. I and the entire NL Lock team take Nick’s legacy very seriously and pledge to continue his tradition of innovation and commitment to high-quality, reliable, cost-effective and cleverly designed products. Acquisition of NL Lock brand by Clay Miller, CEO of LTI and Q Security, will add great value to the brand while also carrying on the Miller family tradition of innovation in and service to the security industry.

NL Lock will persist and consolidate its position as the only global supplier of high security locks for safes that can offer:

    • in-house fully integrated processes from development & engineering to production & sales
    • in-house electronics SW & HW development and production
    • original patented designs

Stay tuned… we have several great new products in the pipeline!
