Master Lock K1710W81 – Frequently Asked Questions

1) Which Master Lock padlocks does the K1710W81 key work with?
The K1710W81 is a factory-cut Master Lock replacement key for the 1710, 1714 and 1790 locks, plus the master-keyed versions of each: 1710MK, 1714MK and 1790MK. One key covers all six of those model families, which is what makes it useful when a facility runs a mix of them.
2) Does the Master Lock K1710W81 come already cut, or do I need a locksmith to cut it?
It ships cut. The K1710W81 is pre-cut to Master Lock's factory specification and ready to use straight away, so there is no trip to a locksmith and no key machine needed. That is the difference between this and a blank like the BEST 1AF patented blank or the Kaba Ilco CH1C, both of which are uncut key blanks that still have to be machined to a keyway and bitting.
3) Will this key open my existing 1710 padlock, or is it cut to a different bitting?
A cut key only turns the cylinder it is bitted for. The K1710W81 is the factory service key for the 1710, 1714 and 1790 families (including the MK versions), so it matches locks supplied on that key code. If your padlocks were keyed to a different code or keyed alike to your own system, this key will not operate them. Match the key number stamped on your original key before ordering.
4) What is the difference between a Master Lock K1710W81 key and a key blank like the Kaba Ilco CH1C?
The Master Lock K1710W81 arrives factory-cut to manufacturer specification and works in Master Lock 1710, 1714, 1790, 1710MK, 1714MK and 1790MK locks with no further work. The Kaba Ilco CH1C is a key blank for the Arrow 1C keyway in nickel silver construction, so it is an uncut piece that a locksmith must cut to an existing key or code before it will operate anything. If you need a spare that a maintenance tech can hand out the same day, the cut key is the one that ships ready to use; if you are cutting keys in house on Arrow 1C cylinders, the blank is the correct form.
5) I need a cut operating key, but my cylinders are BEST small format interchangeable core, not Master Lock. What should I order?
The Master Lock K1710W81 is cut to Master Lock's own key specification for the 1710, 1714, 1790 and MK variants of those locks, so it will not enter a BEST core. For a BEST interchangeable core opening, the BEST 1A3A2KS531KS681 is an operating key supplied cut, for a green core in the A keyway. Match the keyway letter and the core color your facility is standardized on before ordering, since an operating key is cut to one specific core combination.
6) Is the Master Lock K1710W81 a genuine OEM part or an aftermarket copy?
Genuine Master Lock service part, catalogued by the manufacturer under service parts, cylinders and keys. It is cut to the same manufacturer specification as the keys originally supplied with the compatible locks, so operation in the cylinder matches the original.
7) I manage a commercial building and need spare keys for maintenance staff. Is this the right part to order?
Yes, for facilities running Master Lock 1710, 1714 or 1790 padlocks. The K1710W81 is rated for commercial use and is the part to stock as a spare or a replacement for a lost key. Order one per key holder; it arrives cut and needs no further work, so a lock does not sit out of service waiting on a key machine.
8) Is there a patented-keyway alternative to the Master Lock K1710W81 for controlling key duplication?
The K1710W81 is a standard factory-cut Master Lock service key for the 1710, 1714, 1790, 1710MK, 1714MK and 1790MK families, so duplication control comes from your own key management program rather than from the key itself. If restricted duplication is the requirement, the BEST 1AF series preferred patented blank key is a patented blank, which limits who can legally originate copies. Note it is a blank in the BEST 1AF keyway, so it requires BEST cylinders and a cutting operation, not a drop-in swap for a Master Lock key.
9) For a facility standardizing spare keys, when does the Master Lock K1710W81 make more sense than stocking blanks?
Stock the K1710W81 when the locks in service are Master Lock 1710, 1714, 1790, 1710MK, 1714MK or 1790MK and you want a commercial replacement part that goes straight into use with no cutting step. Blanks such as the Kaba Ilco CH1C for the Arrow 1C keyway or the BEST 1AF patented blank make sense only where you have a key machine and the matching cylinders, since both are uncut. Facilities without an in-house locksmith generally keep cut keys on the shelf for each lock family they run.
10) What is the difference between the master-keyed 1710MK locks and the standard 1710 when ordering this key?
The K1710W81 is listed as the cut replacement key for both, so the same part number covers the standard 1710, 1714 and 1790 and the MK master-keyed versions. On an MK lock the change key and the master key are separate keys, so confirm which one you are replacing before you order.
11) Can a locksmith duplicate this key instead, or do I need the factory-cut one?
If you want a duplicate rather than a factory key, a locksmith works from a blank in the right keyway, for example the Kaba Ilco CH1C nickel silver blank for Arrow 1C or a BEST 1AF patented blank for BEST systems. Those are not interchangeable with Master Lock keyways. The K1710W81 is the direct route for the 1710, 1714 and 1790 families because it arrives already cut to the factory specification.
