Master Lock K81KM1710CRM – Frequently Asked Questions

1) Will the Master Lock K81KM1710CRM key work on my 1710MK padlocks?
Yes. The K81KM1710CRM is the factory-cut master key made specifically for the Master Lock 1710MK lock, so it operates the 1710MK cylinder it was cut for. It is a genuine Master Lock service part, not a generic blank, so no cutting or fitting work is needed before you put it into service.
2) Is the K81KM1710CRM a blank I have to cut, or is it ready to use?
It arrives already cut. Master Lock cuts it to original factory specification for the 1710MK, so a facility manager can put it straight on the ring. If you want a blank to cut yourself on your own machine, that is a different item, for example the BEST 1AF Series patented key blank or the Kaba Ilco CH1C blank for the Arrow 1C keyway.
3) I lost the master key for my building's Master Lock system. Do I have to rekey all the locks?
Not if the locks are 1710MK units. Ordering the K81KM1710CRM cut master key restores master keying on the existing hardware, so there's no need to pull cylinders or replace lock assemblies. If the key was lost rather than simply worn out, weigh the security exposure of a key in unknown hands before you simply replace it.
4) Will a K81KM1710CRM master key open other Master Lock padlocks in my building?
Only ones keyed into the same 1710MK master key system. The key is cut for the 1710MK lock, so padlocks on a different keyway or a different master system won't turn. If your locks are mixed, identify each lock's model before ordering rather than assuming one master key covers the fleet.
5) What is the difference between the Master Lock K81KM1710CRM and a key blank like the BEST 1AF or Kaba Ilco CH1C?
The Master Lock K81KM1710CRM arrives factory-cut to work the Master Lock 1710MK lock, so it is ready to use out of the package. The BEST 1AF Preferred Patented Blank Key and the Kaba Ilco CH1C are key blanks, which means they carry no cuts and have to be originated or duplicated on a key machine before they operate anything. The CH1C is a blank for the Arrow 1C keyway in nickel silver construction. If you need a working master key with no locksmith step, the cut key is the one; if you cut your own keys in house, the blanks are the format you want.
6) Can I use a BEST cut key instead of the Master Lock K81KM1710CRM?
No. The BEST 1A3A2KS531KS681 is a cut operating key for a BEST Green Core cylinder in the A keyway, so it is cut to a BEST keying system and will not enter or turn a Master Lock cylinder. The K81KM1710CRM is cut specifically for the Master Lock 1710MK lock as a genuine service part. Cut keys are keyway and system specific, so match the key to the lock brand and cylinder it has to operate.
7) What's the difference between this Master Lock cut master key and a BEST cut operating key?
Both are pre-cut keys, but they serve different levels and different hardware. The K81KM1710CRM is a master key for Master Lock 1710MK locks, meaning it is intended to operate multiple locks in a keying hierarchy. The BEST 1A3A2KS531KS681 is an operating key for a BEST green core in the A keyway, which is a single change-key level key for BEST interchangeable core cylinders. They are not interchangeable.
8) I need an operating key, not a master key. What are my options?
The Master Lock K81KM1710CRM is a master key, cut to give master-level access to the 1710MK lock rather than single-door operation. For a change or operating key on a BEST small format interchangeable core system, the BEST 1A3A2KS531KS681 is a cut operating key for a Green Core in the A keyway. For any other keyway, a blank such as the BEST 1AF patented blank or the Kaba Ilco CH1C for the Arrow 1C keyway can be cut to your own change key combination.
9) Which of these keys can be restricted so tenants cannot get copies made?
The BEST 1AF blank is a preferred patented blank key, and patented blanks are the format used where duplication needs to be controlled. The Master Lock K81KM1710CRM is a factory-cut master key supplied as a genuine Master Lock service part for the 1710MK lock, ordered from the manufacturer rather than cut from an open-market blank. The Kaba Ilco CH1C is a standard nickel silver blank for the Arrow 1C keyway.
10) Is this master key meant for commercial use or home use?
It's a commercial service part. Master Lock classes the K81KM1710CRM as commercial, and it is aimed at buildings running master key hierarchies, offices, schools, healthcare, retail, warehouses, multi-tenant residential and municipal facilities where one key has to open many locks.
11) Is the K81KM1710CRM a genuine Master Lock part or an aftermarket copy?
Genuine. It comes out of Master Lock's Service Parts, Cylinders and Keys program as a replacement part, cut to original manufacturer tolerances so it inserts and rotates the way the original did.
