BEST BES-1AF11P27 – Frequently Asked Questions

1) What do I have to give BEST when ordering a 1AF Preferred cut key?
Two things are required on every 1AF Preferred cut key order: the keymark and the marking number. Those come off the key or the key records for the system you are matching. Without them the key cannot be cut to your existing system, because a cut key is combinated to your specific keying, not a generic blank. You also pick the keyway (1P, 2P, 7P, 8P, 9P or 10P) and the level of key you need.
2) What is the difference between an operating key and a control key on a BEST interchangeable core system?
The 1AF Preferred cut key is offered at five levels: operating, control, master, submaster and grandmaster. An operating key throws the lock. A control key does not open the door, it pulls the interchangeable core out of the housing so you can swap cores without taking the lock apart. Master, submaster and grandmaster keys sit above the operating key in a masterkeyed hierarchy and open progressively wider groups of doors. Order the level that matches the role of the person carrying it.
3) Can a locksmith or a hardware store copy a BEST 1AF Preferred patented key?
No. The 1AF Preferred is a patented key system with restricted duplication, so blanks are not sold across the counter and a walk-in shop cannot legally cut a copy. Additional keys come through the system of record using the keymark and marking number. That restriction is the point of the system for a property manager or facility: it stops tenants and staff quietly building their own key ring.
4) Will BEST Preferred keys work with the BEST Peaks cores already in my building?
Yes. The Preferred system is backwards compatible with all BEST Peaks systems and with other major brands of locking hardware, which is what lets a building move onto Preferred without replacing every cylinder at once. Practically that means you can convert in phases, area by area, and keep the existing openings keyed and working while you do it.
5) Which keyways does the BEST 1AF Preferred patented key come in?
Six Preferred keyways are cut on the 1AF: 1P, 2P, 7P, 8P, 9P and 10P. The keyway has to match the cores already in your building, so pull the keymark off an existing key or your key records before ordering. Each of the six is available at operating, control, master, submaster and grandmaster level.
6) Do I need special key machines to service a BEST Preferred key system in house?
No special equipment. Preferred keys are cut on industry standard key cutting machines, and the cores are simple to combinate and service, so an in house maintenance shop or your regular locksmith can run the system rather than sending every rekey back out. That matters most on a large portfolio where turnover drives the rekey volume.
7) I need a plain key blank for an Arrow keyway, not a BEST Preferred key. What should I order?
Then this isn't the part. The 1AF Preferred is a cut, combinated, patent-restricted key that requires a keymark and marking number. For an unrestricted blank on an Arrow keyway, the Kaba Ilco CH1C is a nickel silver key blank cut to the Arrow 1C keyway. It's a blank you cut yourself, with none of the duplication control the Preferred system carries.
8) How do I add keys for a new tenant without rekeying the whole floor?
Order additional operating keys at the keymark and marking number already assigned to that opening's keying, in the keyway your cores use (1P, 2P, 7P, 8P, 9P or 10P). Because the Preferred system is masterkeyed, the new keys sit under the existing master and submaster levels, so your staff keys keep working and nothing above the tenant changes. If you want the tenant's old key dead, that's a core change, not a key order, and the control key is what pulls the core.
9) Is the BEST 1AF Preferred key suitable for a residential rental or is it a commercial product?
It's a commercial product. The 1AF Preferred cut key is built for commercial door hardware, and the applications it's aimed at are office buildings, schools, hospitals, government facilities, multi-tenant properties, industrial plants, retail and hospitality. A landlord with a handful of units gets the same restricted duplication out of it, but the value shows up when you're masterkeying a portfolio of doors under one hierarchy.
