About Master Lock: Master Lock is a popular American brand best known for padlocks, combination locks, and small format door locks (like gym lockers, filing cabinets, etc.). Master Lock keys (for padlocks, for instance) are usually smaller brass keys and often have a code stamped on them (like “M1”, “M5” for padlocks, or other alphanumeric codes). Master Lock also has some keyed systems like the Edge™ Key Control padlocks which are designed so that only authorized persons can get blanks. Generally, duplicating a Master Lock key can be straightforward if you have the key – many padlock keys can be copied at a locksmith. Alternatively, Master Lock will provide duplicates if you supply the code (you can often order by code on their website or through a dealer). But that requires knowing the code and waiting for shipping. If you lost the code tag or have many locks, it can be a hassle.

Why Mikiz for Master Lock Keys:

• Copies Without Codes: If you don’t have the little code card or tag for your Master padlock, no worries. Mikiz can decode the cuts from just a clear photo of the key. There’s no need to remember or find the key code. This is great for older locks where the documentation is gone. You simply scan the key, and Mikiz figures out the bitting (the cut pattern) automatically, using image analysis – saving you from manual measuring or guessing.
• All Master Keys Accepted: Mikiz can handle virtually any Master Lock key type – from the common M1 padlock key (used in millions of standard padlocks) to the Master Lock Edge™ high-security keys that normally require special authorization. If it’s a Master Lock key and you have a legit copy in hand, chances are we can duplicate it. This includes Master Lock padlock series, Master Lock door knob/deadbolt keys, and even some American Lock-branded keys (since American Lock is a Master Lock subsidiary with similar blank profiles).
• Bulk Orders Friendly: Do you manage a lot of padlocks (for a school, gym, construction site, etc.)? Mikiz makes it easy to get multiple copies of a Master Lock key. Need 10 copies for your team? 20 for your lockers? Just select the quantity in the app. We’ve helped coaches, facility managers, and contractors get bulk key orders done in one go, without the tedious process of visiting a shop and copying each key one by one. This can save significant time.
• Quality Duplicates: Even though Master Lock keys aren’t usually “high-security,” we ensure the duplicates are cut accurately and with good materials. Mikiz uses quality brass or nickel-plated blanks that match Master Lock specifications. Your duplicate will be as sturdy and reliable as the original. This is important if the keys will be used frequently or in rough conditions (like outdoor padlocks). A well-cut key also helps prevent wear on the lock.
• Speed and Simplicity: The Mikiz process is extremely fast for Master Lock keys, given their simplicity. You can often scan and complete an order in under a minute, and we often ship the same day for Master Lock key orders. Many customers are pleasantly surprised to get their padlock keys in 2–4 days via mail, which is often faster than coordinating a trip to a locksmith who might have to order the blank if they don’t stock it.

How to Duplicate Master Lock Keys with Mikiz:

1. Scan Your Key: Use the Mikiz app to take a clear photo of your Master Lock key. If it’s a small key (like a tiny locker key), get close so the details are visible. A white background can help the cuts stand out. The app will confirm if it has enough detail. It will also automatically detect the key type (e.g., it might recognize “M1” padlock key pattern).
2. Place Your Order: Indicate how many copies you want. If you have several different Master Lock keys (for different locks) you need copied, you can scan each one and add them all to your cart before checkout – the app supports multiple keys per order. Enter your shipping address and payment info to finalize the request.
3. Cutting & Delivery: Mikiz’s system will decode the key cuts from your image (or use the code if it was clearly visible) and cut your duplicates. Each key is tested on a gauge to ensure the cuts are correct. We then send them out in a plain envelope. There’s no activation or programming needed – these are physical keys, so once they arrive, just use them in your locks like the originals. They should turn smoothly and securely. Keep one as a backup or distribute extras as needed, and enjoy the peace of mind that comes with having spares.

Master Lock padlocks and keys may be simple, but losing a key can still put you in a bind. With Mikiz, you’ll never be locked out for long – a spare can be on its way to you almost as soon as you realize you need it.
