BEST CORMAX 1AM Series Standard Shape Blank Key

The BEST CORMAX 1AM Series is a patented commercial key blank engineered for facilities that need strong key control without replacing an entire lock system. Its unique side pin design prevents unauthorized duplication — patent protection runs through 2027 — and the blank operates on both CORMAX and Standard cores, making it the go-to choice for phased retrofits where CORMAX security is added to perimeter and high-value openings while existing hardware stays in place.

Key Features

  • Patented duplication protection through 2027 — restricted key control enforced at the factory level
  • Hybrid core compatibility — works with both CORMAX and Standard cores; no full system replacement required
  • Unique side pin design — strengthens mechanical security beyond standard commercial keyways
  • Standard (1AM) bow shape — fits standard key rings and hardware; compatible with high-volume commercial applications
  • Available in keyways MJ, MK, ML, and MM — select the keyway that matches your existing CORMAX system
  • Five key types — Operating, Control, Master, Submaster, and Grandmaster blanks available on this listing

BEST BES-1AM1MJ11KS716KS800 – Frequently Asked Questions

1) Will a BEST CORMAX 1AM key work in my existing BEST standard interchangeable cores, or do I have to swap every core?
No core swap needed. The CORMAX 1AM blank operates both CORMAX cores and Standard cores, so you can add CORMAX security to perimeter and high-value openings while the rest of the building keeps its existing cores. That is what makes it usable for a phased retrofit instead of a full system replacement.
2) Can a locksmith copy a BEST CORMAX 1AM key at a hardware store?
Not legitimately. The 1AM is a patented blank with patent protection running through 2027, and duplication is restricted at the factory level. Its side pin design is the mechanical half of that control: the slot at the key tip actuates a side pin in the core, so a blank without that feature will not turn the cylinder even if the cuts are copied.
3) Which keyway do I order for a BEST CORMAX M Series system?
The 1AM blank comes in four keyways: MJ, MK, ML, and MM. There is no universal choice here, you order the one that matches the keyway already in your CORMAX system. Pull it from your keying schedule or system documentation before you order, because a key in the wrong M keyway will not enter the core.
4) What is the difference between the Operating and Control key blanks in the BEST CORMAX 1AM series?
An operating key retracts the lock; a control key uses a separate shear line in the interchangeable core to pull the core out of the housing for rekeying or core swaps. Both are cut on the 1AM blank, along with Master, Submaster and Grandmaster blanks. If you maintain your own cores you need control blanks on hand as well as operating keys, since one will not do the other's job.
5) What does the exclusivity level mean when ordering BEST CORMAX key blanks?
It sets how widely your keyway is issued to other end users. Four levels are offered: Non-Exclusive, Two-Digit Zip Code Exclusive, One-Digit Zip Code Exclusive, and National Exclusive. The tighter the level, the fewer other facilities in your geography hold keys in that same keyway. This is a key-control decision, not a physical one, and it has to match the level your existing CORMAX system was set up under.
6) What is the difference between a BEST CORMAX 1AM key blank and a Kaba Ilco CH1C blank?
They serve different lock systems. The BEST CORMAX 1AM Series is a patented commercial key blank with a unique side pin design and patent protection running through 2027, offered in keyways MJ, MK, ML and MM and in Operating, Control, Master, Submaster and Grandmaster types, and it operates both CORMAX and Standard cores. The Kaba Ilco CH1C is a key blank cut for the Arrow 1C keyway in nickel silver construction. If the cylinders on the opening are BEST CORMAX or BEST Standard cores, the 1AM is the blank that fits; an Arrow 1C keyway blank is a separate keyway family and will not enter a BEST core.
7) I need an unrestricted key blank I can duplicate locally - is the CORMAX 1AM the right choice?
No. The BEST CORMAX 1AM Series is a restricted blank: duplication protection is enforced at the factory level under patent through 2027, and it is ordered by exclusivity level, from Non-Exclusive up to Two-Digit Zip Code, One-Digit Zip Code and National Exclusive. For an opening where you want keys cut freely at a local shop, an open-keyway blank such as the Kaba Ilco CH1C for the Arrow 1C keyway is the type of blank to look at instead - though it only fits Arrow 1C cylinders, so the lock has to match.
8) What do I have to specify to order the right BEST CORMAX 1AM blank?
Four things: Key Type (Operating, Control, Master, Submaster or Grandmaster), Keyway (MJ, MK, ML or MM), Exclusivity Level, and Key Stamp. The stamp options are KS716KS800 and KS717KS800. Miss any one of those and the blank can come in unusable for your system.
9) Is the BEST CORMAX 1AM key blank suitable for a hospital or school master key system?
Yes, it is a commercial-grade blank and the type range supports a full hierarchy, Operating through Submaster, Master and Grandmaster, which is what a multi-level institutional system needs. Typical use is commercial offices, healthcare, education, government and municipal buildings, multi-family and hospitality, and industrial MRO programs.
10) Can a Kaba Ilco CH1C be used as a substitute for a BEST CORMAX 1AM control key?
No. A control key on the CORMAX 1AM Series is a distinct key type that removes the interchangeable core, and it is cut on a BEST CORMAX blank in one of the MJ, MK, ML or MM keyways. The Kaba Ilco CH1C is a blank for the Arrow 1C keyway, a different keyway family, so it cannot be cut to a BEST control key combination. Order the 1AM in Control type with the keyway that matches your existing CORMAX system.
11) Is the 1AM a standard key bow, or an oversized one that will not fit our key rings and cabinets?
The 1AM is the Standard bow shape in BEST's CORMAX lineup, so it fits normal key rings and key cabinets, which matters when you are issuing hundreds of keys. BEST also builds CORMAX keys in other shapes including long blade, long nose, round bow, access bow, premium and rectangular bow, but the 1AM is the plain standard profile.
12) Where can I get the full BEST key and core reference before I order blanks?
BEST publishes a Key and Core Brochure PDF covering the CORMAX system, keyways, shapes and core options, and it is attached to the 1AM blank as a system reference. Worth reading alongside your own keying schedule if you are setting exclusivity level and keyway for the first time.

    These keys are sturdy and easy to cut. They fit perfectly with our locks. The only drawback is they are a bit expensive for blank keys, but they are worth it for the quality.

    Key to Convenience

    Posted by Max on Mar 11th 2024

    It's a lifesaver! The standard shape fits smoothly into most locks, and the quality is top-notch. However, I found that it's a bit pricier compared to other blank keys on the market. Overall, if you're looking for reliability and convenience, this key is worth the investment.
