Key copying is one of the most routine locksmith services — fast, inexpensive, and available at dozens of locations across Toronto. But not all key copies are equal, and not every location that offers the service does it well. Understanding what to look for when you need a key copy near you helps ensure the copy works reliably and that the service is handled by someone you can trust with your key.

Where to Get a Key Copy in Toronto

Key copying is available at hardware stores, big-box retailers, some pharmacies, and locksmith shops across Toronto. The quality of the copy depends on the equipment used, the condition of the cutting machine, and the skill of the person operating it. A professional locksmith shop uses precision cutting equipment maintained to a higher standard than the self-serve kiosks found in some retail locations, and the technician can identify when a key is worn or damaged in a way that will affect the quality of the copy.

For standard residential keys — the kind used on most deadbolts and knob sets — the difference between a retail copy and a professional copy is often minimal. For high-security keys, restricted keys, or keys with worn profiles, a professional locksmith is the better choice.

High-Security and Restricted Keys

Not every key can be copied at a hardware store. High-security keys — such as those used with Schlage Primus, Medeco, or Mul-T-Lock cylinders — have patented profiles and secondary security features that require specialist equipment and, in some cases, authorisation from the key's registered owner before a copy can be made. These keys are designed specifically to prevent unauthorised duplication, which is a meaningful part of the security they provide.

Restricted key systems — common in commercial buildings, condominium complexes, and properties with master key systems — operate under similar controls. A key marked "Do Not Duplicate" is a request, not a technical restriction, and many retail locations will copy it anyway. A professional locksmith who understands key control will not copy a restricted key without verifying authorisation, which is exactly the point of the restriction.

When a Key Copy Is Not the Right Solution

There are situations where copying a key is not the appropriate response to the underlying problem. If you need to give access to a new person while removing access from a previous one — a new tenant moving in, a contractor whose work is complete, a former partner — copying a key does not address the issue. The previous key still works. Rekeying the lock is the correct solution: it changes the internal pin configuration of the cylinder so that all existing keys no longer work, and new keys are cut to the new configuration.

Similarly, if a key is difficult to turn in the lock, copying it may reproduce the problem rather than solve it. A worn key that barely operates the lock will produce a copy that barely operates the lock. The underlying issue — a worn key, a worn cylinder, or a combination of both — needs to be assessed before copying.

What to Bring When Getting a Key Copy

For a standard key copy, bring the original key in the best condition available. A key that has been on a ring with many other keys for years may have worn edges that affect the quality of the copy. If you have multiple copies of the same key, bring the one that operates the lock most smoothly — it is likely the closest to the original cut.

For high-security or restricted keys, bring any documentation associated with the key system — a key card, a registration number, or proof of ownership or tenancy. A professional locksmith will ask for this before proceeding with a copy of a controlled key.

Key Copying as Part of a Broader Lock Service

Key copying is often most useful when combined with a broader lock service. Moving into a new property and having the locks rekeyed produces new keys cut to the new configuration — no need to copy old keys that may have been duplicated multiple times over the years. Installing new hardware includes new keys cut to the new cylinder. A professional locksmith who handles the full service provides keys that are cut correctly to the hardware in place, rather than copies of copies that may have accumulated small errors over successive duplications.
