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.

About Product Overview

The HILLMAN Traditional Key Blank is a dependable, ready-to-cut solution for creating spare or replacement house and office keys that work seamlessly with Master Locks. Featuring a classic brass head and a sleek silver finish, this single-sided key blank pairs durability with clarity in profile, making it a smart choice for quick rekeys and reliable everyday use.

  • Key type: House/Office
  • Material and head: Brass head with a durable silver finish
  • Sides: Single
  • Style: Traditional key
  • Model compatibility: Master Locks
  • Key identifiers: Key Krafter Number 57; Traditional EZ Number M4, M5
  • Package contents: 1 key blank

Who this is for: homeowners, landlords, property managers, and DIY enthusiasts who want a trustworthy spare that’s ready to be cut to match their existing Master Locks cylinders. It’s ideal for rekeying entry doors, storage rooms, or any area secured by Master Locks where a traditional, single-sided key profile is preferred.

  • Precisely matched to Master Locks profiles M4 and M5 to minimize guesswork during cutting
  • Brass construction resists wear and maintains precise tolerances over time
  • Silver finish presents a professional look and resists corrosion
  • Single-sided design keeps the key compact and easy to handle in tight locks

How to use: Take this blank to a locksmith or your own key-cutting setup. Identify the M4 or M5 profile using the Traditional EZ Numbers, align the blank in the machine, cut using your existing key pattern, and test in the Master Locks cylinder. With a 1-piece blank and a familiar shape, you’ll have a reliable spare key ready in minutes.

Practical tips: Store blanks in a dry spot to prevent tarnish, and label spare keys with the lock they service for quick future replacements. This Hillman 57 key blank is a practical, long-term solution for households and small workplaces that rely on Master Locks in daily operations.

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.
