BEST 1APWAKS567KS800 – Frequently Asked Questions

1) Which BEST keyway do I order for the 1AP key blank?
The 1AP blank is stocked in seven BEST keyways: WA, WB, WC, WD, WG, WH and WY. The keyway has to match the core it will operate, so pull the keyway letter off the core or off an existing key in the system before ordering. A WA blank will not enter a WB core, and so on down the list, so the keyway is the one thing you cannot substitute on this part.
2) Does the BEST 1AP key blank come cut, or do I need a locksmith to cut it?
It ships uncut. The 1AP is a blank, so it needs to be cut to your existing bitting or to a new code by a locksmith or an in-house key shop with the BEST card. That is the point of buying blanks rather than duplicates: you cut to your own master key schedule as tenants turn over or a core gets rekeyed.
3) Can a tenant get a BEST 1AP key copied at a hardware store?
No, and that is the reason to specify it. The 1AP is a restricted blank that prohibits unauthorized duplication, so a resident or employee cannot walk into a retail counter and get a copy made. For a property manager or a school running a master key schedule, that keeps key control with whoever holds the system records instead of with whoever holds the key.
4) Will an Ilco CH1C key blank work in a BEST 1A Series interchangeable core?
No. The Ilco CH1C is a key blank milled for the Arrow 1C keyway, so its blade profile enters Arrow 1C cylinders, not BEST cores. The BEST 1AP standard key blank is the one made for BEST 1A Series interchangeable core systems, and it is ordered by BEST keyway - WA, WB, WC, WD, WG, WH or WY - so the blade matches the core already in the door. A blank in the wrong keyway family cannot be corrected at the key machine; the milling is in the blank, not in the cut. Confirm which keyway the core is stamped for before ordering, then cut the 1AP in that keyway.
5) My building has Arrow cylinders on some doors and BEST cores on others - what blank do I order for each?
Order by the keyway of the cylinder, not by the door. For openings running BEST 1A Series interchangeable cores, the BEST 1AP standard key blank is the correct uncut blank, ordered in the matching BEST keyway - WA, WB, WC, WD, WG, WH or WY. For the Arrow 1C keyway openings, the Ilco CH1C is the blank cut for that profile, in nickel silver. A facility running both families keeps both blanks on the shelf; neither one substitutes for the other, and a keying record should note which openings sit in which family so future cutting stays consistent.
6) What are the KS567, KS609 and KS800 stamp options on the BEST 1AP blank?
Those are the factory key stamps. Every 1AP carries KS800 on the back, and the front is your choice of KS567 or KS609. Both front stamp options are offered in all seven keyways. Pick the stamp that matches what the rest of your key system already carries so the keys in a facility read consistently when a key is turned in or audited.
7) Can the BEST 1AP blank be used for master keys and grand master keys, not just change keys?
Yes. The 1AP is the standard blank for BEST 1A Series master key systems, so the same blank cuts change keys, master keys and the higher levels of the schedule. What separates them is the bitting your locksmith cuts, not a different part number. Order in the keyway your system was built in and cut each level from the same stock.
8) Is the BEST 1AP key blank the same as an Arrow 1C blank?
No. The 1AP is a BEST blank for BEST 1A Series keyways (WA through WY). The Ilco CH1C is a nickel silver blank cut for the Arrow 1C keyway, which is a different manufacturer's small format IC keyway. They are not interchangeable, so match the blank to the brand and keyway stamped on your cores. If your building runs Arrow IC cores, the CH1C is the blank to order instead of this one.
9) Both are just uncut key blanks - what actually makes the BEST 1AP different from the Ilco CH1C?
The difference is the keyway profile milled into the blade, which decides which cylinder the key will enter. The Ilco CH1C carries the Arrow 1C keyway and is supplied in nickel silver. The BEST 1AP is a standard key blank for BEST 1A Series interchangeable cores and is ordered in a specific BEST keyway, with front and back key stamps - KS567 or KS609 on the front, KS800 on the back - so cut keys can be identified in a masterkeyed system. If the job is expanding an existing BEST masterkey system, the 1AP in the system's keyway is the blank that integrates with it.
10) How many BEST 1AP blanks should I order for a building rekey?
Count one blank per key you will hand out, plus the control and master keys, plus a shop reserve. On a multi-tenant or campus rekey that usually means the change keys for every opening, two or three per unit for occupants, and a stock of uncut blanks left with the key shop for turnover. Order them all in the same keyway letter as your cores, and split the front stamp (KS567 or KS609) only if your system already distinguishes key levels by stamp.
