BEST BES-2A1A1KS473KS800 – Frequently Asked Questions

1) Which BEST keyway do I order for a 2A large round key blank?
The 2A large round blank is stocked 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 the key will operate, so pull the keyway letter off your existing BEST cores or your keying schedule before ordering. Order the wrong letter and the blank will not enter the keyway, no matter how it is cut.
2) What is the difference between a control key and an operating key on a BEST 2A blank?
Key Type is an ordering choice on the 2A blank: Control, Grandmaster, Master, Operating, or Submaster. A control key is what pulls the interchangeable core out of the housing, so it is a maintenance key, not a door key. Operating keys work individual openings, submaster and master keys open progressively larger groups, and the grandmaster sits at the top of the hierarchy. Specify the level you need on the order so the blank matches its place in your keying schedule.
3) Will a BEST 2A key blank work in my existing BEST small format interchangeable cores?
The 2A blank is made for BEST combinating and keying systems, so keys and cores work together as one system. The controlling factor is the keyway: order the blank in the same keyway letter as the cores you already have, and it will enter and can be cut to your existing bitting. Twenty keyways are offered, from A through TE.
4) I need blanks for Arrow cores, not BEST. What do I order?
A BEST 2A blank is cut for BEST keyways only and will not enter an Arrow core. For Arrow, the Kaba Ilco CH1C blank is the Arrow 1C keyway blank, in nickel silver. Match the blank to the lock brand and keyway first; the bow shape is a separate decision.
5) Can an Ilco CH1C key blank be used in place of a BEST 2A blank?
No. The Ilco CH1C is a key blank cut for the Arrow 1C keyway in nickel silver, so its blade section is made to enter Arrow cylinders. The BEST 2A large round bow blank is supplied in BEST keyway sections including A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD and TE, and it is the keyway section that decides whether the blade enters the core at all. Both are key blanks in the same sense, but they belong to different keyway families and will not interchange. Order the BEST blank in the keyway letter that matches the cores already in the facility.
6) What is the point of the large round bow on a BEST 2A key versus the standard 1A?
Bow shape is about grip and identification, not function. The 2A is the large round bow, which is easier to grab and easier to tell apart on a crowded ring in a high-use building. BEST offers the same blanks in other bows: 1A standard, 1AP premium, 3A large rectangular, 4A access, and 9A blockout blade. The cut and keyway do the work; pick the bow that suits how the key gets carried and sorted.
7) Can I get BEST 2A keys stamped for my facility?
Yes, key stamping is available on the 2A blank and it is ordered as an option on the key. Stamping personalizes keys to an institution or organization, which makes them easier to sort by building or department and discourages unauthorized duplication. Two stamp options are offered, KS208KS800 and KS473KS800. For a school district, hospital, or REIT running a large keying schedule, stamping is what keeps the key hierarchy legible in the field.
8) Do BEST 2A key blanks come cut or do I have to cut them myself?
They ship as blanks. The 2A is an uncut key blank, so it has to be cut to the bitting for your system by a locksmith or an in-house key machine before it will operate anything. Confirm the keyway and the key level (control, master, operating, and so on) against your keying schedule before you cut, since a cut blank cannot be reassigned to a different keyway.
9) A locksmith stocks Arrow blanks already. What does the BEST 2A blank add that the Arrow blank does not cover?
The Ilco CH1C covers Arrow 1C cylinders only, as a single keyway blank. The BEST 2A blank is ordered against a keying hierarchy as well as a keyway: it is available as an operating, master, submaster, grandmaster or control key, and control is the one that pulls and replaces a BEST interchangeable core rather than throwing the lock. A shop servicing BEST small format cores needs the control level in its own right, and that level has no counterpart in a single Arrow blank. Both are stocked as replacement parts for existing cylinders.
10) If the large round bow is too bulky for a tenant key ring, what BEST blank should be used instead?
BEST supplies the same blade in several bow shapes: 1A standard bow, 1AP premium bow, 2A large round, 3A large rectangular, 4A access bow and 9A blockout blade. The 2A large round bow is chosen for grip and for quick identification in high-use commercial settings; where a slimmer profile suits a tenant ring better, the 1A standard bow carries the same keyway sections. The bow shape changes handling and identification, not which cylinder the key enters, so a change of bow does not change the keying system. Key stamping to an institution or organization is offered as an option either way.
11) Is the BEST 2A key blank suitable for a commercial building or is it a residential key?
This is a commercial key blank. The 2A is built around BEST's institutional keying systems and gets used in office buildings, schools, hospitals, government facilities, warehouses, multi-tenant residential, and retail, where a master key hierarchy and controlled duplication actually matter. For a single-family house with off-the-shelf residential locks, this is the wrong blank.
12) How many BEST 2A blanks do I need to order to cover a whole master keyed system?
It depends on the levels in your schedule, and the 2A is ordered per level: you buy operating keys for the individual doors, submaster and master keys for the groups above them, a grandmaster if the system runs that deep, and control keys for the maintenance staff who pull cores. Each of those is a separate key type selection in the same keyway. Most facilities keep control keys tightly limited and stock operating blanks in quantity.
