Master Lock K1710KM SL35 – Frequently Asked Questions

1) Which Master Lock locks does the K1710KM master key work with?
The K1710KM (also marked SL35) is the factory master key for Master Lock 1710, 1714, and 1790 series locks. It gives master-level access on those three series only; it is not a universal Master Lock key, so a lock outside the 1710/1714/1790 family needs its own key.
2) Is the K1710KM a master key or an individual change key?
Master key. It operates at the master level across compatible 1710, 1714, and 1790 series locks in a master-keyed hierarchy, rather than opening a single lock. If you need a key that opens only one specific lock, order the change key for that lock instead.
3) I manage a building with master-keyed Master Lock padlocks and cabinet locks. Is this the right key to add for a new maintenance tech?
If the locks in that system are 1710, 1714, or 1790 series, yes: the K1710KM is the master key for that hierarchy and is intended for commercial master-keyed installations such as offices, schools, healthcare, retail, and multi-tenant properties. Confirm the series number stamped on your locks first, because the key will not operate other Master Lock series.
4) Will the K1710KM work in a BEST or Arrow cylinder?
No. It is cut for Master Lock 1710/1714/1790 cylinders and will not enter a different manufacturer's keyway. For BEST small format interchangeable core work you want a BEST key in the matching keyway, such as the 1A3A2 operating key for an A keyway green core; for Arrow, an Ilco CH1C blank cut to the Arrow 1C keyway.
5) Is the Master Lock K1710KM a cut key or a blank that a locksmith still has to cut?
The K1710KM (SL35) ships as a finished OEM master key for Master Lock 1710, 1714, and 1790 series locks, so it arrives ready to operate the lock rather than needing to be cut. If you need an uncut blank to originate a key on your own machine, that is a different class of part - the BEST 1AF Preferred Patented Blank Key and the Kaba Ilco CH1C blank for the Arrow 1C keyway are both key blanks, supplied uncut for the locksmith to bit.
6) We run a BEST small format interchangeable core system - can the Master Lock K1710KM operate those cylinders?
No. The K1710KM is keyed to Master Lock 1710, 1714, and 1790 series locks only and will not enter or turn a BEST core. For a BEST green core in the A keyway, the operating key to order is the BEST 1A3A2KS531KS681 cut key. Keep the two systems separate: a master key is only a master within the system it was cut for.
7) Is the K1710KM a genuine Master Lock part or an aftermarket copy?
Genuine OEM. It is a Master Lock service part from the Service Parts, Cylinders and Keys line, cut to factory specification so it operates the supported 1710, 1714, and 1790 cylinders correctly. That matters on a master-keyed system, where an off-spec blank can bind or damage the master wafers.
8) Is the K1710KM a blank I have to cut, or is it ready to use?
It ships as a finished service key, not a blank. That is the difference between this and a key blank like the BEST 1AF patented blank or the Kaba Ilco CH1C blank for the Arrow 1C keyway, both of which have to be cut on a machine to a code or a customer key before they operate anything.
9) I need to add keys to an Arrow-keyed door in the same building - is the K1710KM the part?
It is not. The K1710KM is a Master Lock service part for the 1710, 1714, and 1790 padlock series. For an Arrow 1C keyway, the Kaba Ilco CH1C is the nickel silver key blank cut to that keyway. Buildings often carry both, so match the key to the cylinder brand and keyway on each opening rather than to the building.
10) For a facility standardizing on patented key control, how does the Master Lock K1710KM compare?
The K1710KM is a genuine OEM Master Lock replacement service part supplied as a commercial-grade finished master key for the 1710, 1714, and 1790 series. Key control there comes from sourcing the OEM part. If your program is built instead on a patented keyway with restricted blank distribution, the BEST 1AF Preferred Patented Blank Key is the blank in that family. The two approaches serve different key control models, so decide which system the facility is standardizing on first.
11) How do I order the Master Lock K1710KM, and is there more than one version?
One part only, ordered as K1710KM SL35. There are no finish, keyway, or length options to specify, so quantity is the only decision.
