BEST BES-9AF91P17 – Frequently Asked Questions

1) Which BEST keyway do I order for the 9AF blockout blade key blank?
The 9AF Series blockout blade blank is sold by keyway, and there are six to pick from: 1P, 2P, 7P, 8P, 9P and 10P. The keyway is not something you choose for preference, it has to match the keyway already in your BEST Preferred cores. Pull an existing key or a core out of one door and read the keyway stamp off it, then order that same letter/number combination. Order the wrong keyway and the blank will not enter the plug at all, cut or uncut.
2) Can a local locksmith cut the BEST 9AF Preferred key blank, or does it have to go back to the manufacturer?
Cutting is straightforward: the BEST Preferred key system uses industry standard key cutting equipment, so a shop with normal code and duplicating machines can cut the 9AF blank. What is controlled is getting the blank itself. The Preferred system is patented through 2024, which is the point of it, restricted duplication. Anyone can cut it once they have it in hand, but they cannot buy the blanks off the shelf, so your key control stays intact.
3) Will BEST 9AF Preferred keys work in the BEST Peaks cores already in my building?
Yes. BEST states the Preferred patented system is backwards compatible with all BEST Peaks systems, along with other major brands of locking hardware, so you can move a building onto Preferred in stages rather than swapping every core in one weekend. Keyway still governs: the 9AF blank comes in 1P, 2P, 7P, 8P, 9P and 10P, and the blank has to match the keyway of the core it is going into.
4) I manage a multi-building property on BEST SFIC cores. Does ordering 9AF Preferred blanks mean rekeying everything?
No rekey is forced by the blank. BEST Preferred runs on the same interchangeable core technology, so a core swap at the doors you want protected is the whole job, no door prep, no new lock bodies. The Preferred blanks are masterkeyed like any BEST system, so a new patented level can sit under your existing master structure. Because Preferred is backwards compatible with BEST Peaks, the buildings you have not converted yet keep working on what they have.
5) Is the Ilco CH1C key blank a substitute for the BEST 9AF blockout blade key blank?
No - they cut for different cylinders. The Ilco CH1C is a nickel silver key blank for the Arrow 1C keyway. The BEST 9AF blockout blade blank is a Preferred Patented Keys component that works with compatible BEST Preferred and Peaks system locks, and it ships with an extractor key. A CH1C will not enter a BEST Preferred keyway, and the 9AF will not enter an Arrow 1C cylinder, so the choice follows whichever cylinder is already in the door.
6) What is the extractor key included with the BEST 9AF blank actually for?
The 9AF blockout blade blank ships with an extractor key. A blockout blade is a key blade element used to block the keyway, and the extractor is the tool that pulls it back out again. That pairing matters if you are using blockout blades to take a door out of a masterkey program temporarily: without the matching extractor you have blocked a keyway you cannot easily clear. The two are supplied together for that reason.
7) Do I need a patented restricted key blank, or will a standard key blank do?
Depends on whether you care who else can copy the key. A standard blank, say the Ilco CH1C in the Arrow 1C keyway, nickel silver, is an open blank; any hardware counter or kiosk can duplicate a key cut on it. That is fine for a storage room or a low-traffic interior door. The BEST 9AF Preferred blank is the other case: patented through 2024, so blanks are controlled and a tenant or a departing employee cannot walk out and get a copy made. Schools, healthcare, government and multi-tenant residential are where that matters. If the doors hold anything, buy the patented blank.
8) I need an unrestricted blank a locksmith can duplicate freely - what do I order instead of a patented BEST blank?
For Arrow 1C cylinders, the Ilco CH1C is a nickel silver blank with no patent control attached to it. The BEST 9AF blockout blade blank is part of a patented system - patented through 2024 - which is what gives it controlled key duplication in the first place. If the goal is open duplication, the patented blank is working against you; if the goal is holding the key count down across an office or campus master key program, it is the reason to buy it.
9) How do I pick the right keyway when ordering a BEST 9AF blank versus an Ilco CH1C?
The BEST 9AF blockout blade blank is ordered by keyway, in 1P, 2P, 7P, 8P, 9P and 10P - so you match the blank to the Peaks keyway already assigned to that building or master key level. The Ilco CH1C is a single-keyway blank cut for Arrow 1C, so there is no keyway selection to make on it. Both are Key Blanks series parts, and both run on standard key cutting equipment in the case of the 9AF.
10) Is the BEST 9AF key blank a commercial-grade product or a residential one?
Commercial. BEST lists the 9AF Preferred blank as a commercial door hardware item, and the applications it is built around are office buildings, school master key programs, healthcare access control, government and municipal buildings, multi-tenant residential, industrial security and retail chains. It is a key control product for facilities that run a master key program, not a house key.
11) Where do I find the BEST Preferred keying documentation before I set up a master key system?
BEST publishes a Preferred Patented Key System keying document, BA-3420, and it is the thing to read before you commit a keying schedule to paper. It covers the Preferred system rather than any one blank. Do the keying design first and the blank order second, because the keyway you standardize on there, one of 1P, 2P, 7P, 8P, 9P or 10P, is what you will be buying blanks in for years.
