BEST BES-1AF11P17 – Frequently Asked Questions

1) Can any locksmith buy and cut a BEST Preferred 1AF key blank?
No, not freely. Preferred is a patented restricted system, so the blanks are controlled rather than sold over the counter like a standard blank. Once you have authorization, cutting is straightforward: the 1AF blank runs on industry standard key cutting equipment.
2) What is the difference between the operating, master and control key options on the BEST 1AF blank?
The key level is an ordering choice, not a different blank family. Five levels are offered in each keyway: operating (the day to day user key for one core), submaster, master and grandmaster (progressively wider access across a masterkeyed system), and control. The control key is the one that pulls and installs the interchangeable core rather than throwing the lock, so a locksmith or facilities team servicing cores needs it separately from the user keys.
3) Will a BEST Preferred 1AF key work in my existing BEST Peaks cores?
Yes. The Preferred 1AF blank is backwards compatible with all BEST Peaks systems, which is what lets a building move to Preferred without replacing every core at once. Match the keyway (1P, 2P, 7P, 8P, 9P or 10P) to what your cores are pinned for.
4) Do I need to replace my locks to move to the BEST Preferred key system?
Usually not. Because the Preferred system works on BEST interchangeable core technology and is backwards compatible with existing BEST Peaks systems and other major brands of locking hardware, the upgrade is typically done by swapping cores and issuing new keys rather than changing out locksets. That is what makes a building-wide rekey economical.
5) Can I have the keys stamped for a master key system?
Yes, a custom stamp can be specified when ordering, which is how most facilities mark key level and change number (for example a room number or a master designation) so a large system stays traceable. The 1AF blank supports masterkeyed configurations, so stamping matters more here than on a single-door key.
6) What is the difference between a BEST Preferred 1AF blank and a standard blank like the Kaba Ilco CH1C?
Two different worlds. The Kaba Ilco CH1C is a nickel silver blank for the Arrow 1C keyway, a conventional open blank anyone can buy and cut. The BEST Preferred 1AF is part of a patented, restricted system built around BEST interchangeable cores, with operating, submaster, master, grandmaster and control levels. If you just need a spare for an Arrow cylinder, the CH1C is the right part; if you are maintaining a keyed system where duplication has to be controlled, the Preferred blank is what you order.
7) Both the BEST 1AF and the Kaba Ilco CH1C are listed as key blanks - what actually separates them?
They are both uncut key blanks in the Key Blanks series, but they serve different cylinder platforms. The CH1C is a nickel silver blank for the Arrow 1C keyway. The BEST 1AF is a Preferred patented blank built around BEST interchangeable core technology, ordered by keyway (1P, 2P, 7P, 8P, 9P, 10P) and by key type, including control keys used to remove and install interchangeable cores - a function an Arrow blank has no equivalent for.
8) Is the BEST 1AF key blank suitable for a commercial building, or is it a residential product?
It is a commercial door hardware component, used for office buildings, schools, hospitals, government and municipal buildings, multi-tenant residential properties, industrial plants and retail. The draw for a property manager or institutional buyer is patent protection plus a control key level, so keys cannot be duplicated at a hardware store counter.
