BEST BES-2A1A2KS473KS800 – Frequently Asked Questions

1) What do I need to specify when ordering a BEST 2A cut key?
Four things settle a BEST 2A cut key order. Keyway (A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD or TE), key type (Operating, Master, Submaster, Grandmaster or Control), the keymark, and the marking number. Keymark and marking number are both required entries, so pull them off the existing key or your key records before you order. The keymark is what ties the cut to your system; without it the key cannot be combinated to your locks.
2) Will a BEST 2A key work in my existing BEST locks?
Only if the keyway and the keymark match your system. BEST 2A keys are cut to order and combinated through BEST's own keying system, and they come in twenty keyways (A through TE, including DD, TB, TC, TD and TE). A key cut on the C keyway will not enter an A keyway cylinder. Match the keyway letter and the keymark stamped on your current key and the new one will operate the same openings.
3) What is the difference between a control key and an operating key on a BEST system?
On a BEST small format interchangeable core system the control key removes and installs the core; it does not throw the lock. The operating key retracts the latch on the openings it is combinated to. BEST 2A keys are cut in both, plus Master, Submaster and Grandmaster levels, so a facility can order a maintenance control key and tenant operating keys off the same keyway. If you are ordering a key to swap cores during turnover, it is the control key you want, not another operating key.
4) I need a replacement key for a BEST lock, do I order a cut key or a key blank?
Order the cut key if you want it ready to use. The BEST 2A comes cut and combinated to your keymark, so it works on arrival. A blank is uncut brass or nickel silver that a locksmith still has to cut on a machine to your bitting, which is the right buy only if you cut in house. Blanks are stocked for other systems too, like the Ilco CH1C for the Arrow 1C keyway. For a property manager or facilities team replacing a lost key, the cut key is the one to order.
5) Where do I find the keymark and marking number to order a BEST cut key?
Both are on the key itself or in your key records. The keymark is the code BEST assigns to your keying system and it is normally stamped on the key bow along with the marking number that identifies the individual key within that system. If you hold a key schedule from the original hardware submittal, both codes are on it. Both are required entries when ordering a BEST 2A cut key, because they are what the key is cut to.
6) Will an Ilco CH1C key blank work in place of a BEST 2A cut key?
No. The Ilco CH1C is a nickel silver key blank cut for the Arrow 1C keyway, so it is uncut brass stock for a different manufacturer's keyway and will not enter a BEST cylinder. The BEST 2A large round bow key is supplied already cut, ordered against a specific BEST keyway - A, B, C, D, DD, E, F, G, H, J, K, L, M, N, O, R, TB, TC, TD or TE - and a specific key type such as Control, Grandmaster, Master, Submaster or Operating. A blank in an Arrow keyway cannot be cut to a BEST bitting because the keyway section itself differs.
7) How do I pick between a master key and a submaster key for my building?
It depends how deep your keying tree runs. Submaster covers one group of openings, say a floor or a department. Master sits above several submasters. Grandmaster sits above the masters and is what you order for a campus or a portfolio with multiple buildings under one system. All four levels plus the operating key are available as BEST 2A cut keys on the same keyway, so you can extend an existing tree without changing hardware. Order the level that matches the access you actually want to hand out, and keep the count of higher-level keys small.
8) Can I get BEST 2A keys stamped for key control?
Yes, stamping is offered on the BEST 2A key in two options, KS208KS800 and KS473KS800. Stamping marks the key to a specific institution or organization, which does two jobs: it lets staff identify at a glance which system a loose key belongs to, and it discourages walk-in duplication at a hardware counter. Institutions running a formal key control policy usually take the stamping.
9) What is the difference between the BEST 2A bow and the 1A, 3A, 4A and 9A keys?
The bow is the head of the key, and BEST offers several shapes across the same cut. The 2A is the large round bow, easy to grab and easy to pick out of a ring by feel. The 1A is the standard bow and 1AP the premium bow, the 3A is large rectangular, the 4A is an access bow, and the 9A is a blockout blade. Facilities often assign different bow shapes to different key levels, so a maintenance master is recognisable from a tenant operating key without reading the stamp. The choice is about handling and identification, not about which locks the key opens.
10) Can I add keys to my BEST system later without rekeying the locks?
Yes, as long as you order to the same keyway and keymark. BEST 2A cut keys are combinated into the existing keying system rather than supplied loose, so an additional operating key or a new submaster drops into a system already installed. Nothing at the door changes. That is the usual route for adding staff, replacing a lost tenant key, or extending a master level to a floor that was not covered when the system was first set up.
11) When do I order a key blank instead of a cut key?
Order a blank such as the Ilco CH1C when a locksmith is cutting to a bitting on site and the keyway matches the cylinder - the CH1C is nickel silver stock for the Arrow 1C keyway. Order the BEST 2A large round bow key when you want the key delivered finished to a BEST system: it ships cut to the keyway and key level you specify, with optional stamping to tie the key to an institution and discourage unauthorized duplication. The BEST 2A route means no cutting step at the property; the blank route means the bitting stays with whoever holds your key records.
12) Are BEST 2A cut keys suitable for a hospital or school key system?
Yes. The 2A is a commercial-grade cut key and is used across office buildings, schools, healthcare, government and municipal buildings, industrial and warehouse sites, multi-tenant residential and retail. What makes it work at that scale is the keying hierarchy: operating keys for rooms, submasters and masters for departments and floors, a grandmaster over the whole system, and a control key for core swaps. That lets a facilities department standardise every opening on one keyway and one key schedule.
