BEST BES-1AK1B126140 – Frequently Asked Questions

1) What do I need to specify when ordering a BEST Peaks 1AK cut key?
Four things settle a Peaks 1AK cut key order. Key type: Control, Grandmaster, Master, Submaster, or Operating. Keyway: B1 through B10. Pin size: 6-pin 140 Series, 6-pin 150 Series, or 7-pin 150 Series. Then the keymark and marking number off your existing system, both of which are required at order entry so the key is cut to your system's combination rather than a generic bitting. Pull the keymark from the stamping on a key already in the system or from your keying records before you order.
2) Will a BEST Peaks 1AK key work in my existing BEST cores?
Only if those cores are Peaks cores in the matching keyway and pin count. Peaks is a patented restricted system, and the cylinders and cores operate only with authorized Peaks keys, so a 1AK Peaks key will not turn a standard BEST A2 or A4 core, and a standard BEST key will not turn a Peaks core. Match the keyway letter (B1 to B10) and the pin size, 6-pin 140 Series, 6-pin 150 Series, or 7-pin 150 Series, to what is in your cores. A 6-pin key will not operate a 7-pin core.
3) Can I get BEST Peaks keys cut by any locksmith or hardware store?
No. Peaks keys are available only through authorized BEST distributors, which is the whole point of the system: unauthorized duplication at a hardware counter is what it prevents. That is why the order requires your keymark and marking number, so the key is cut against the system of record. For a property manager or facility with turnover, this is the difference between recovering a key and rekeying a building.
4) Which BEST keyway do I order, and how do I find out what I already have?
Ten Peaks keyways are cut in the 1AK profile: B1, B2, B3, B4, B5, B6, B7, B8, B9, and B10. Keyways are not interchangeable, so a B3 key will not enter a B7 core. The keyway is normally recorded on your keying schedule and stamped alongside the keymark on a key already in service. In a multi-building portfolio, different keyways are often assigned per building or per tenant specifically so keys cannot cross over, so check the schedule for the building you are ordering for rather than assuming the whole property is on one keyway.
5) Can an Ilco CH1C key blank be used in place of a BEST Peaks 1AK cut key?
No. The Ilco CH1C is a nickel silver key blank cut to the Arrow 1C keyway, so its blade profile will not enter a BEST Peaks cylinder. The Peaks 1AK cut key uses BEST's patented Peaks profile in the B1 through B10 keyways, and Peaks cylinders and cores are built to operate only with authorized Peaks keys supplied through authorized BEST distributors. An Arrow-profile blank is a different keying system, not a cross-reference.
6) What is the difference between buying a key blank and a BEST Peaks 1AK cut key?
A blank such as the Ilco CH1C ships uncut in nickel silver on the Arrow 1C keyway and has to be cut locally by whoever holds the code. The BEST Peaks 1AK is supplied as a finished cut key on the Peaks profile, ordered by key type - Control, Grandmaster, Master, Submaster or Operating - so the level in the master key system is specified when it is ordered rather than decided at the machine. Peaks blades are restricted to authorized BEST distribution, so open blank stock is not an equivalent path to the same key.
7) What is the difference between a control key and an operating key on a BEST Peaks system?
A control key removes and installs the interchangeable core itself; it does not throw the lock. An operating key retracts the latch on one opening. Between them sit the master keys: a submaster opens a defined group of openings, a master opens a broader group, and a grandmaster opens across master groups. All five are orderable in the Peaks 1AK profile. Facilities usually order operating keys in volume and hold control keys tightly, since anyone with the control key can pull cores.
8) Is this a cut key or a blank?
The Peaks 1AK is supplied cut, bitted to the keymark and marking number you provide at order. That is different from a key blank like the Kaba Ilco CH1C, which ships uncut in the Arrow 1C keyway and has to be bitted by whoever receives it. If you want stock to cut yourself, a blank is what you want; if you want a working key for a specific opening delivered ready to use, order the Peaks cut key.
9) Can I expand a BEST Peaks system later, or am I locked into what I install now?
Peaks is upgradeable with BEST CORMAX or BEST Preferred components, so a system started on Peaks can be moved up later without abandoning the hardware. For a school district or hospital that expects to add wings or re-tier its masterkeying over time, that matters more than the price of the first order.
10) I lost a master key for our BEST Peaks system, can I just order a replacement?
A replacement can be cut, and Peaks 1AK master, grandmaster, and submaster keys are all orderable, but the order needs the keymark and marking number from your keying records. Those two values identify the combination; without them the key cannot be bitted to your system. Also weigh whether replacing a lost master is the right call at all, since a master key loose in a building is usually a reason to rekey the affected group rather than reissue.
11) What is the difference between the 140 Series and 150 Series pin sizes on BEST Peaks keys?
Three combinations are cut in the 1AK profile: 6-pin 140 Series, 6-pin 150 Series, and 7-pin 150 Series. The 140 and 150 designations identify the core family the key is cut for, and the pin count has to match the core, since a 6-pin key cannot operate a 7-pin core. Seven pins give a larger pool of combinations, which is what large masterkeyed facilities use to keep tiers from colliding. Read the core family and pin count off your keying schedule before ordering.
12) Is the BEST Peaks 1AK key suitable for residential use, or is it commercial only?
Peaks 1AK is a commercial product, built around restricted distribution and masterkeying rather than the single-door residential case. The value shows up where there are many openings and controlled access matters: office towers, campuses, healthcare, government buildings, multi-tenant property, and industrial restricted areas. A single-family landlord with a handful of doors gets little from it beyond the duplication control.
