Master Lock K1710W81KM SL10 – Frequently Asked Questions

1) Which Master Lock padlocks does the K1710W81KM key work with?
The K1710W81KM cut key is made for the Master Lock 1710, 1714, 1790, 1710MK, 1714MK and 1790MK padlocks. It is a factory service part for that lock family, so one key covers all six models within a keying program rather than needing a separate key type per model.
2) Is the K1710W81KM a master key or a change key?
It is a master key, cut to the SL10 master key specification. That means it is intended to operate all compatible 1710 and 1790 series locks set up under SL10, not a single individual padlock. If you need a key that opens only one lock, a master-cut key is the wrong part to order.
3) Does this key come already cut, or do I have to have it cut at a locksmith?
It ships factory cut to the SL10 specification. No on-site cutting, no blank to originate, no code machine needed. Put it straight into service. If your system is keyed to a different master specification, this cut will not turn your locks.
4) Is the Master Lock K1710W81KM a key blank I need to have cut, or is it already cut?
The K1710W81KM arrives factory-cut to the SL10 master key specification for 1710, 1714, 1790, 1710MK, 1714MK and 1790MK locks, so no on-site cutting is needed. If you want an uncut blank to originate your own bitting, that is a different type of part: the BEST 1AF Series Preferred Patented Blank Key and the Kaba Ilco CH1C blank for the Arrow 1C keyway are both key blanks, and both require a code machine or duplicator before they will operate anything.
5) Will a BEST or Ilco key work in a Master Lock 1710 padlock?
No. The K1710W81KM is a genuine Master Lock service part cut for the 1710, 1714, 1790, 1710MK, 1714MK and 1790MK lock families. The BEST 1A3A2KS531KS681 is an operating key for a BEST green core in the A keyway, and the Kaba Ilco CH1C is a blank for the Arrow 1C keyway - different keyways and different lock platforms entirely. For Master Lock 1710/1790 series cylinders, stay with the Master Lock cut key.
6) I manage a campus with Master Lock padlocks. Can I add this key to an existing master keying system?
Yes, if the system is built on SL10 with 1710 or 1790 family padlocks. The key is pre-cut to that master specification so it drops into an established program for facilities, campus locksmith shops, healthcare, government and multi-tenant properties. It is a commercial-grade service part, not a residential item.
7) What is the difference between this Master Lock cut key and a key blank?
The K1710W81KM arrives cut to a specific master specification (SL10) and is ready to operate the matching padlocks. A blank, such as the BEST 1AF Series patented key blank or the Kaba Ilco CH1C blank for the Arrow 1C keyway, is uncut brass or nickel silver stock that a locksmith still has to cut to your bitting. Order a cut key when you know the spec; order a blank when you are originating keys in house.
8) Will this Master Lock key work in a BEST or Arrow cylinder?
No. It is cut for Master Lock 1710 and 1790 family padlocks only. For BEST small format interchangeable core work you would look at a BEST operating key such as the 1A3A2KS531KS681 for green core, A keyway; for Arrow, the Ilco CH1C blank covers the Arrow 1C keyway. Keyways do not cross between these manufacturers.
9) I need a master-level key for an existing keying system - which of these cut keys applies?
Both the Master Lock K1710W81KM and the BEST 1A3A2KS531KS681 are cut keys rather than blanks, but they serve different systems. The K1710W81KM is cut to the SL10 master key specification for Master Lock 1710 and 1790 family padlocks and drops into a master keying program built on those locks. The BEST 1A3A2KS531KS681 is an operating key for a green core in the A keyway. Match the key to the cylinder platform already in the field.
10) Is the K1710W81KM a genuine Master Lock part or aftermarket?
Genuine. It is catalogued as an official Master Lock replacement service part for cylinders and keys, so the cut and keyway match factory specification for the 1710 and 1790 padlock families.
11) What is the difference between the BEST 1AF blank and the Ilco CH1C blank if I am stocking blanks alongside cut keys?
The BEST 1AF is a patented blank in the BEST 1AF series, which means duplication is controlled. The Kaba Ilco CH1C is a nickel silver blank for the Arrow 1C keyway, an open commercial blank. Neither is interchangeable with the Master Lock K1710W81KM, which is supplied already cut to SL10 for the 1710 and 1790 padlock series.
