Since its founding in 1993, GMS Industries, Inc. has earned a reputation as a premier lock cylinder manufacturer by remaining true to the concept of producing lock cylinders that retain all original manufacturers' keying specifications.

As a result, GMS cylinders are an ideal alternative to the original branded cylinders with their reduced cost and ability to accept original pins when pinning to an original master key system.

Our current products include an extensive line of lock cylinders and rekeyable padlocks in all the popular door hardware configurations and keyways. All these products are manufactured within the exact tolerances required to ensure their keying performance rival that of the originals'.

In additional, our MX Series key control cylinders are also available when end users demand a high degree of key control. MX Series cylinders can offer similar levels of protection against unauthorized key duplication at only a fraction of the cost when compared to other patented key control systems.

At GMS Industries, Inc., we will continue to strive for excellence with our belief in customer service, product innovation and quality assurance.
