Master Lock K17BOX – Frequently Asked Questions

1) Will the Master Lock K17BOX key blank work on my Master Lock No. 17 padlocks?
Yes. The K17BOX blank is cut for Master Lock No. 17 locks specifically, so it will key into No. 17 series cylinders. It is a genuine Master Lock service part, not an aftermarket equivalent, so the blade profile matches the No. 17 keyway. It won't fit other Master Lock keyways, so confirm the lock body is stamped No. 17 before cutting.
2) Are these blanks uncut, or do they come already cut to a key code?
They are uncut blanks. The K17BOX ships as raw key blanks for duplication or replacement, which means you need a key machine and either an existing key to copy or the code for the No. 17 cylinder. If you need a key already cut to a code, a blank is the wrong part.
3) I need key blanks for Arrow or BEST cylinders, not Master Lock. What should I order instead?
The K17BOX only matches the Master Lock No. 17 keyway, so it is no use on other brands. For an Arrow 1C keyway, the Kaba Ilco CH1C blank is the nickel silver blank for that keyway. For BEST, the 1AF Series patented blank is the key blank option. Keyways are brand and profile specific, so match the blank to the cylinder, not to the lock's appearance.
4) Will a Kaba Ilco CH1C key blank work in a Master Lock No. 17 padlock instead of the K17BOX?
No. The Kaba Ilco CH1C is a key blank cut for the Arrow 1C keyway with nickel silver construction, so its blade profile is made for Arrow cylinders. The Master Lock K17BOX blank is made specifically for Master Lock No. 17 locks, so it is the blank to stock for No. 17 series cylinders. The two are not interchangeable even though both are uncut blanks.
5) I need a key that already works, not a blank - is the K17BOX the wrong item?
Yes, if you need a ready-to-use key. The Master Lock K17BOX supplies uncut blanks that a qualified locksmith cuts to your No. 17 cylinder. When you need a factory-cut operating key instead, a cut key such as the BEST 1A3A2KS531KS681 operating key for green core, A keyway, is the type of item to look for - it ships in the Cut Keys series rather than as a blank. Cut keys are keyway and key-code specific, so they only work in the system they were cut for.
6) How many key blanks come in a Master Lock K17BOX?
Fifty blanks per box. That quantity is aimed at facilities running a lot of No. 17 locks, where a locksmith or maintenance shop cuts keys in batches rather than one at a time. The boxed pack keeps them organized in storage.
7) Should I buy key blanks or an already-cut operating key for my locks?
Blanks like the K17BOX make sense if you have a key machine in house and want to cut on demand across a lot of No. 17 locks. If you only need one or two working keys and have no cutting capability, order a cut key instead, for example the BEST 1A3A2KS531KS681 operating key for a green core in the A keyway is supplied as a cut key rather than a blank.
8) What is the difference between the Master Lock K17BOX and the BEST 1AF blank key?
Both are uncut key blanks, but they serve different cylinder platforms. The BEST 1AF Series Preferred Patented Blank Key is a patented-keyway blank in the BEST 1AF series, which means duplication is restricted to that patented key system. The Master Lock K17BOX is a standard commercial service blank for Master Lock No. 17 locks, supplied 50 to a box for key duplication and replacement across larger installs. Choose by the cylinder platform already in the field.
9) For a facility standardizing key stock, how does the K17BOX compare to buying blanks like the BEST 1AF or Ilco CH1C?
The Master Lock K17BOX is bought by the 50-pack box, which suits a facility keeping duplication stock on hand for many No. 17 locks at once. The BEST 1AFKEY and the Kaba Ilco CH1C are both key blanks as well, but each is tied to its own keyway - the 1AF patented series for BEST and the Arrow 1C keyway for the Ilco. If a site mixes lock brands, expect to carry a blank per keyway rather than one blank for everything.
10) Is the Master Lock K17BOX rated for commercial use or is it a consumer part?
Commercial. Master Lock classifies the K17BOX as a commercial-grade service part under cylinders and keys, and it is used in office buildings, schools, healthcare, warehouses, multi-tenant residential, government facilities and retail.
11) Is the K17BOX a genuine Master Lock replacement part?
It is. The K17BOX is catalogued by Master Lock as a replacement part for the No. 17 series, supporting cylinder and key service programs. That matters where a facility standardizes on one keyway and needs every duplicate to gauge the same.
