BEST BES-1A1A1KS473KS800 – Frequently Asked Questions

1) Which keyways does the BEST 1A key blank come in?
The 1A standard bow blank is cut in 20 BEST keyways: A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD, and TE. The keyway has to match the core you are opening, so pull the keyway letter off an existing key or off the core stamping before you order. Ordering the wrong letter gives you a blank that will not enter the plug at all.
2) What is the difference between a control key and an operating key on BEST blanks?
The 1A blank is ordered by key level: Control, Grandmaster, Master, Submaster, or Operating. Control is the one that pulls the interchangeable core out of the housing, it is not a key that unlocks doors. Operating is the single-door user key, Master and Submaster open groups of doors, and Grandmaster sits at the top of the system. Order the level that matches the position the key holds in your combinating chart, since the level determines how it gets cut, not the blank shape.
3) Will the BEST 1A blank work in my BEST small format interchangeable core?
Yes, provided the keyway letter matches. The 1A is made for BEST combinating and keying systems and mates with BEST cores and cylinders. Keyway is the gate: a C keyway blank goes into a C core and nothing else. Everything else, bow shape and key level, is about handling and hierarchy rather than whether the blade enters the plug.
4) I need keys for an Arrow keyway, not BEST. Does this blank work?
No. The 1A is a BEST blank in BEST keyways only, and an Arrow core will not accept it. For an Arrow 1C keyway you want the Kaba Ilco CH1C blank, which is a nickel silver blank cut for Arrow 1C. Different manufacturer keyway families are not interchangeable no matter how similar the bow looks.
5) Can I get BEST keys stamped with our building or department name?
Custom stamping is offered on the 1A blank, and there are two stamp ranges to specify, KS208KS800 and KS473KS800. Facilities use this to mark keys by institution or department and to discourage unauthorized duplication. If you run a large key system, stamping is what keeps a recovered key traceable to the opening it belongs to.
6) Which BEST key bow should I pick if the standard 1A is not what I want?
The 1A is the standard bow, a plain flat head that stacks well on a ring and takes a stamp. The same BEST blank family also runs 1AP premium bow, 2A large round, 3A large rectangular, 4A access bow, and 9A blockout blade. Pick the larger round or rectangular bows when maintenance staff need more grip or a bigger stamping face, and the 9A blockout when you want the blade profile restricted. Bow choice does not change the keyway or the cut.
7) Is the BEST 1A key blank suitable for a school or hospital master key system?
Yes. The 1A is a commercial blank built around BEST combinating systems, and it is ordered at every level a facility system needs, Operating through Grandmaster, plus the Control key for core removal. That is the full hierarchy an educational, healthcare, government, or multi-tenant property key system is built on. Order in the keyway your existing cores are pinned to and the new keys drop straight into the chart you already run.
8) Do BEST 1A blanks come cut, or do I have to cut them myself?
They are blanks. The 1A ships uncut, ready to be combinated to your system by a locksmith or your own key shop. What you specify at order time is the keyway, the key level it will be cut to, and any stamping. The actual bitting comes from your combinating chart, not from us.
9) Is a BEST Cormax key the same as the 1A blank?
The 1A standard bow blank is carried under BEST Cormax key blank sourcing, so it is the blank you order for those BEST small format systems. Match the keyway letter to the core, since Cormax and other BEST cores are still keyway specific and the letter on the core is what decides which blank enters.
