So, you need a spare key — maybe for a roommate, a cleaner, a friend, or just peace of mind. But what is actually needed to duplicate a key? Can anyone copy any key? And where should you go?

Today’s blog post is meant to guide you to what’s required to copy most keys in Canada, especially if you live in an apartment or rent out your property.

What You Need to Duplicate a Key

Duplicating a key is often a fast and simple process, here’s what you need:

1. The Original Key or A Physical Copy of the Original Key

Most key copies require an existing, physical key. A photo won’t do in most cases (learn more in our post: Can You Copy a Key from a Picture?). As long as you have a working original key (or working copy), the new key can usually be made in minutes.

2. The Right Key Blank

Not all keys are the same — they need to be matched with a compatible key blank before they’re cut. At MiniFob, we carry the most common blanks, like:

  • KW1 (Kwikset)
  • SC1 (Schlage)
  • WR5 (Weiser)
  • Y1 (Yale)
  • Mailbox and padlock blanks

3. Access to a Key Cutting Machine

Key duplicators use a specialized machine that traces your original key and cuts the new blank to match. Some stores do this manually, while others use automatic or laser-guided cutters for better precision.

You can visit a key cutting location (like our MiniFob locations) — or if you’re starting your own side hustle, check out our key cutting machines and blanks online.

What If My Key Says “Do Not Copy”?

Keys labeled “Do Not Duplicate” or restricted keys (like Medeco or security keys) may not be copyable without special authorization. If you’re a tenant and your key has this label, it’s best to ask your landlord for permission or check your lease agreement.  

Pro tip: Medeco key duplication is only available at our FobToronto headquarters due to legal and security restrictions.

Why You Might Need Spare Keys

You might want a key copy for:

  • A roommate or new tenant
  • Short-term rental guests
  • Visiting family or cleaners
  • Emergency backups (for when you lose yours!)

We get it — and that’s why we make copies fast, on the spot, and with a lifetime guarantee at MiniFob!

Final Thoughts: What Is Needed to Duplicate a Key?

To duplicate a key, you’ll need a working key (original or copy), the right blank, and access to a key cutter. It’s a quick and simple process — and one that can save you a lot of hassle down the road. Whether you’re a tenant, landlord, or property manager, having spare keys on hand is always a smart move.
