Fred J. Helweg is a Master Locksmith who has been in the Locksmithing trade since 1953. We are an authorized dealer of Medeco, Kaba Ilco and Best Access Systems products. We have our own restricted keyway that cannot be duplicated by anyone except us.

A restricted keyway is a lock and key blank which a manufacturer has set up a restricted level of sales and distribution. Restricted keys are often protected by patent, which prohibits other manufacturers from making unauthorized productions of the key blanks.

We have vast experience in creating large scale, robust, master key systems for commercial and residential applications. We've developed techniques that resist the inherent vulnerabilities of mechanical lock systems.

Locks are an integral part of your overall security. We believe that quality doors, quality locks and a quality alarm system equal the best security.
