Founded in January 1999 as a joint venture between Sjaak van der Meer and Ronald Brouwer, Casino Locking Systems (CLS) brings over three decades of locksmithing excellence combined with deep, specialized knowledge of the casino industry.
Our journey began by serving Holland Casino, where we developed tailor-made locking solutions for gaming tables, slot machines, and building security expertise we continue to refine and apply today.
At CLS, we deliver a comprehensive suite of security products, from high security locks and key management systems to cash & tip boxes, trolleys, safes, seals, and seal bags, designed specifically for casinos. We partner with leading technology manufacturers like BiLock, an Australian patented high-security system, to ensure our clients receive the most reliable and robust solutions.

What truly sets CLS apart is our holistic approach. We don’t just supply locks, we design and implement entire key & lock plans customized to your casino’s layout, staffing, and operational protocols. Every key and cylinder is precision assembled in our own facility in the Netherlands, ensuring rapid deployment, impeccable quality, and dependable service . That’s why, uniquely, every employee uses just one key, drastically simplifying access control and boosting security.
From our base in Rotterdam and Alphen aan den Rijn, we serve a prestigious global clientele and ensuring secure operations across Europe and beyond.
At CLS, we’re more than a supplier, we’re your strategic partner in security. With fast, efficient, and tailored solutions, we empower casino operators to manage risk, protect their assets, and maintain trust at the gaming floor and beyond.
