Lockey LOC-OSK-SC – Frequently Asked Questions

1) Will the Lockey oversized knob fit a 2200 or 2500 keyless lock I already have installed?
Yes. The oversized knob retrofits the 2000 Series locks, and Lockey lists 2200, 2210, 2500, 2900 and 2950 as covered models. It goes on as a straight replacement for the existing knob, with no modification to the lock body and no extra hardware to buy.
2) Do I have to replace the whole Lockey lock to get a bigger knob, or can I just swap the knob?
Just the knob. The 1-3/4 inch oversized knob is a component-level replacement that retrofits onto an installed 2000 Series lock, so the lock body, the mounting and the existing combination all stay as they are. Nothing about the lock is drilled or altered to accept it.
3) Will the Lockey 1-3/4 inch oversized knob work on a narrow stile aluminum storefront lock?
Yes, narrow stile 2000 Series applications are among the ones the knob retrofits, along with surface mount deadbolts, combination deadbolts and hook bolt models. Worth noting on a glass front door: the knob itself is 1-3/4 inches across, so allow for that added projection past the lock face where a door sits close to a frame stop or an adjacent leaf.
4) How big is the Lockey oversized knob compared to the standard one?
It measures 1-3/4 inches in diameter. That is the whole point of the part: more surface to grip and turn than the standard knob supplied on the 2000 Series, which matters on gates, exterior openings, and anywhere users are wearing gloves or have limited hand strength.
5) What finishes does the Lockey oversized knob come in for matching existing door hardware?
Five: Antique Brass, Bright Brass, Jet Black, Satin Chrome and Satin Nickel. If you are standardizing a building, Satin Chrome and Satin Nickel are the ones that sit closest to the brushed silver hardware on most commercial openings; Jet Black suits exterior gate and fence work.
6) Can I put the Lockey oversized knob on a gate lock or a DC-powered Lockey lock?
Yes. Beyond the standard deadbolt models, the knob is used with latch locks, gate applications, single combination locks and DC locks. Gate hardware is where the larger 1-3/4 inch diameter earns itself, since those are usually operated outdoors with gloves on.
7) Is the Lockey oversized knob a lever, and can I get a lever instead for accessibility?
It is a knob, not a lever. Handle type is knob, in a round 1-3/4 inch oversized profile. If your opening has to be operable without tight grasping or twisting of the wrist, a knob is the wrong choice regardless of diameter and you want a Lockey lever trim model instead.
8) Is the Lockey oversized knob rated for commercial traffic or is it a residential part?
Commercial. Lockey classes the oversized knob as commercial-grade, and it is specified into office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and municipal buildings. For a property manager cycling a gate or a back-of-house door hundreds of times a day, that is the intended duty, not a light residential swap.
9) I manage a property with several Lockey keypad locks in different finishes. Can I order oversized knobs to match each one?
You can. The oversized knob is sold by finish across five options, so a mixed building can be brought up one door at a time with each knob matched to the hardware already on that opening. The retrofit is the same on every 2000 Series lock, so the finish is the only variable you are choosing per door.
