Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Designed for Chicago locks

Chicago locks are common in both residential and commercial settings, and this Hillman blank is engineered to align with their single-shear, traditional keyway. The IN8/SL1/RO1 designations map to well-established key profiles, making it a dependable choice when you need a duplicate that works reliably with your existing cylinders.

Ideal use cases

  • Creating spare keys for household doors and office entrances that use Chicago-style cylinders.
  • Stocking a locksmith’s toolkit with a trusted blank that cuts consistently on standard key-cutting machines.
  • Replacing lost or damaged originals without altering hardware or security setups.
  • Labeling and organizing a maintenance closet with clearly identified blanks for quick retrieval.

How to use

  1. Bring the Hillman IN8/SL1/RO1 blank to a licensed locksmith or use a trusted key-cutting machine.
  2. Have an existing Chicago-lock key as a reference, or provide the IN8/SL1/RO1 profile details to ensure accurate duplication.
  3. Test the new blank in the corresponding lock to confirm smooth operation and correct alignment with pins.
  4. Label and store the spare in a secure location to prevent loss and ensure ready access when needed.

Care and handling

Keep the blank dry and clean to prevent corrosion and ensure clean cuts. Store away from heavy impact or grinding dust, and handle with standard key-cutting precautions to maintain the integrity of the blade edge.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
