BEST 1A3A3KS531KS681 – Frequently Asked Questions
1) Will a BEST A keyway operating key work in my BEST Green Core cylinders?
Yes, provided your cores are BEST Green Core and cut to the A keyway. This is an operating key for the A (Standard) keyway, made for BEST Green Core lock cylinders. Keyway is the gate: an A keyway key will not enter a core broached for a different BEST keyway, so check the keyway stamp on your existing key or your keying schedule before ordering.
2) Is an Ilco CH1C key blank a substitute for a BEST A keyway key?
No. The Ilco CH1C is an Arrow 1C keyway blank in nickel silver, and Arrow 1C is a different keyway from BEST A. It will not enter a BEST A broached core. Both are small format interchangeable core style blanks, which is why they get confused, but the keyway has to match the core broach or the key does not go in. For BEST Green Core openings, stay with the BEST A keyway key.
3) Can an Ilco CH1C key blank be used in place of a BEST operating key for a Green Core A keyway?
No. The Ilco CH1C is a key blank cut for the Arrow 1C keyway in nickel silver, so its blade profile is made to enter Arrow 1C cylinders. The BEST operating key is made for the A keyway used with BEST Green Core cylinders. Two keys of different keyways will not interchange even when the bitting looks similar, because the keyway milling decides whether the blade enters the plug at all. For a BEST Green Core opening, stay on the A keyway key.
4) What does the Duplication Prohibited stamping on a BEST key actually do?
It is a security marking stamped on both sides of the key, used to signal that the key is not to be copied. It supports key control policy, which is why it shows up on institutional and multi-tenant systems where a facility tracks who holds which key. It is a stamping, not a patented restricted keyway, so treat it as a policy control that your locksmith or key control program enforces.
5) Can this BEST operating key be used in a masterkey system, or is it change-key only?
It works inside BEST masterkey applications, so it can be cut as a change key at an individual opening or fit into a multi-level masterkeying scheme. What it is depends entirely on how it gets cut and where it sits in your keying schedule, so a property manager standardizing a building should hand their locksmith the existing schedule rather than ordering blind.
6) I need more keys for BEST locks in my building. Do I order a key or a whole core?
If the lock already works and you just need additional or replacement keys for existing holders, the operating key is what you order. You only need a new core when you are rekeying the opening, changing who has access, or the keyway on the core does not match the keys you want to carry. Adding keys to an existing BEST Green Core opening does not require touching the lockset or the door prep.
7) How do I know which BEST keyway my existing cores are before I order keys?
Look at a working key: BEST keys carry the keyway letter, and your keying schedule or the original hardware submittal will list it too. The key here is the A (Standard) keyway. If your building was keyed on a different BEST keyway letter, an A key is the wrong part, and on a facility with multiple keyways you need the letter that matches each core, not one key for the whole site.
8) What is the difference between ordering a key blank and ordering a BEST operating key for a Green Core A keyway?
A blank such as the Ilco CH1C is supplied uncut in nickel silver as a Key Blanks item, so it has the keyway profile but no bitting until a locksmith cuts it to a code or duplicates an existing key. The BEST operating key for the A keyway is supplied as an operating key for BEST Green Core cylinders and carries Duplication Prohibited stamping on both sides, which is what keeps a key control program intact. If you run a masterkey system and need the key control marking, the operating key is the item; if you are cutting your own keys in house on Arrow 1C, the blank is the item.
