KSP is pleased to introduce the availability of its new EX Series small format cores, an affordable restricted or non-restricted keyway system. These cores are available in the popular BEST keyways such as A, B, C, D, E, F, G, H, J, K, L, M, Q and the Arrow 1C & 1D. These cores are operated by an elongated key which will allow you to restore integrity to a key system that has lost its security over time. A few “key” doors can easily be replaced with these EX Cores and the average length keys will not operate these particular doors but the elongated keys will operate the key system already in place. Restricted keyways are available thru contractually authorized distributors and locksmiths only.
