Master Lock K6000BOX – Frequently Asked Questions

1) Will Master Lock K6000BOX key blanks work in W6000 cylinders with 6 pins?
No. The K6000BOX blank is cut for Master Lock W6000 series 5-pin cylinders only. If the cylinder in your door is a 6-pin W6000, this blank is the wrong stock for it and the key will not be a correct fit.
2) Are these Master Lock key blanks uncut, or do they come already cut to a key code?
Uncut. K6000BOX is blank stock, so you cut it on your own machine to the bitting of the W6000 cylinder you're servicing. If you need a key already cut to a code, you want a cut operating key instead, like the BEST 1A3A2KS531KS681 operating key for green core A keyway.
3) Can I use an Arrow 1C key blank instead of the Master Lock K6000BOX for W6000 cylinders?
No. The Master Lock K6000BOX blank is made specifically for 5-pin W6000 cylinders, so the keyway is matched to that cylinder family. The Kaba Ilco CH1C is a key blank cut for the Arrow 1C keyway in nickel silver construction, which is a different keyway and will not enter a W6000 cylinder. If the cylinder on the door is a W6000, stay with the K6000BOX blank; the CH1C is the blank to pull when the opening uses Arrow 1C cylinders.
4) How many key blanks come in a Master Lock K6000BOX?
Fifty blanks per box. It's sold as a single bulk 50-pack, which is the format facilities teams and locksmiths buy when they're duplicating keys for a building's worth of W6000 cylinders rather than cutting one or two.
5) Are these blanks restricted or patented keyway, or can any shop cut them?
K6000BOX is standard Master Lock W6000 blank stock, not a patented restricted blank. That matters if you're choosing a key control program: a patented blank such as the BEST 1AF Series is sold specifically as a preferred patented blank to limit who can duplicate, whereas W6000 blanks are ordinary duplication stock for your own shop.
6) Do I need to replace the whole W6000 lock if I've lost keys, or can I just cut new blanks?
If the cylinder itself is sound, you cut new keys from K6000BOX blanks and keep the existing hardware in service. These are replacement service parts for the W6000 cylinder and key family, so lost or worn keys don't force a full hardware swap. Rekeying the cylinder to a new bitting and cutting fresh blanks to match is the normal fix after a key goes missing.
7) I just need a couple of working keys, not blanks to cut. What should I order?
Blanks and cut keys are two different items. The Master Lock K6000BOX is supplied as uncut blanks in a 50-pack, intended for shops that cut their own keys for W6000 cylinders. If you want a key that arrives ready to use, look to a cut key item such as the BEST 1A3A2KS531KS681 operating key for a green core in the A keyway - that is supplied as a cut key rather than a blank, and it is keyed to a BEST core, not a Master Lock W6000 cylinder.
8) Does the Master Lock K6000BOX give me patent-protected key control like a restricted blank?
The K6000BOX is a standard commercial replacement blank for 5-pin W6000 cylinders, sold in bulk so a facility or locksmith can keep duplication stock on hand. If your key control program depends on a patented, restricted blank that cannot be freely duplicated, that is a different product class - the BEST 1AF Series blank is described as a preferred patented blank key. Choose based on whether the priority is open serviceability of W6000 cylinders or restricted duplication.
9) Is the K6000BOX suitable for a school or hospital keying program, or is it a residential part?
It's designated for commercial use, and the blanks are intended as service stock for W6000 cylinder and key maintenance in office buildings, schools, healthcare, retail, warehouses, multi-tenant residential, and government facilities. Buying blanks in a 50-pack is how a facility keeps rekeying and duplication in house instead of replacing cylinders.
