Needing a key cut is one of those everyday tasks that seems simple until you are not sure where to go. Whether you need a spare house key, a replacement for a lost key, or a copy for a family member, knowing your options — and the differences between them — helps you get the right key cut quickly and at a fair price.

Hardware Stores

Large hardware chains such as Home Depot and Canadian Tire offer key cutting at most locations. These stores use automated key cutting machines that can duplicate standard residential keys quickly and inexpensively. For common key profiles — standard house keys, padlock keys, and basic cabinet keys — a hardware store is a convenient and affordable option.

The limitation is that hardware store machines are designed for standard keys only. High-security keys with restricted keyways, transponder car keys, and keys with unusual profiles cannot be duplicated at a hardware store. Attempting to copy a worn key on an automated machine also tends to produce an imprecise copy that may not work reliably.

Locksmiths

A professional locksmith is the most versatile option for key cutting. Licensed locksmiths have the equipment and expertise to cut standard residential and commercial keys, high-security keys with restricted keyways, keys for older or less common lock profiles, and in many cases automotive keys and fobs. They can also cut keys from a lock's original code rather than from a worn copy, producing a more precise result.

If you have a high-security lock system — such as a Schlage Primus, Medeco, or Mul-T-Lock — a locksmith is the only option for key duplication. These systems use patented keyways that cannot be copied without authorization, and only licensed dealers can cut keys for them. This restriction is a security feature, not an inconvenience.

For residential and commercial properties in the Greater Toronto Area, a local locksmith can often cut keys on-site during a service call, saving you a separate trip. Many locksmiths also offer mobile key cutting, coming to your location rather than requiring you to visit a shop.

Grocery Stores and Pharmacies

Some larger grocery stores and pharmacies have self-serve key cutting kiosks, typically operated by third-party services. These kiosks work for basic residential keys and are convenient if you are already at the store. The quality and accuracy can vary, and the range of key profiles supported is limited. For anything beyond a standard house key, a hardware store or locksmith is a better choice.

What to Bring When Getting a Key Cut

For a standard duplication, bring the original key you want copied. If the key is worn, let the technician know — a good locksmith will advise whether cutting from the worn key is likely to produce a reliable copy or whether cutting from the original code is a better option. For restricted keyway systems, you may need to provide proof of ownership or authorization before a key can be cut.

When You Need More Than Just a Key Cut

If you have lost all copies of a key and cannot locate the original, a locksmith can decode the lock and cut a new key from scratch. If you are concerned about who may have copies of your existing key, rekeying the lock is a faster and less expensive solution than replacing the hardware entirely — and it gives you complete key control from a fresh start.
