Make the right change for each door
Rekey or Replace Your Locks?
Rekeying changes the key that operates a compatible existing lock. Replacement changes the hardware itself. Begin with the problem you need to solve: unknown keys, unreliable hardware, a different access arrangement or an upgrade. More than one answer may fit the same property.

These are different scopes of work, so compare them against the condition of your doors and your intended access plan. Neither option is automatically the best choice for every lock.

| Decision point | Rekey | Replace |
|---|---|---|
| What changes? | The working key for the affected compatible cylinder. | The selected lock or hardware components. |
| What stays? | Suitable existing lock hardware and its general arrangement. | Unaffected door components, subject to compatibility and condition. |
| Unknown key copies | May establish new key access without replacing sound hardware. | Can establish new key access while changing the selected hardware. |
| Worn or damaged hardware | Does not by itself repair wear or damage elsewhere in the lock or door. | May address unsuitable hardware; door or frame issues still need assessment. |
| Different lock features | Generally retains the capabilities of the existing hardware. | Allows discussion of a different suitable hardware arrangement. |
| One key for multiple doors | Depends on compatible cylinders and the intended access system. | May allow a compatible arrangement, subject to assessment. |
| Cost and scope | Depends on the locks, access and work involved. | Depends on hardware selection, fitting and other required work. |
1. Separate key control from a mechanical problem
If a sound lock works reliably but you cannot account for old keys, begin by discussing lock rekeying. This is often the question after moving into a property or losing track of copies. Confirm every door those keys can operate.
If a key sticks, a handle moves loosely or a bolt will not engage properly, explain the symptoms. A fault could involve the cylinder, another lock component or door alignment. Rekeying changes key access; it should not be treated as a cure for every physical problem.
2. Define what you want the door to do differently
Perhaps you want a different hardware arrangement, clearer separation between staff areas or an upgrade to an existing deadbolt. Describe that goal before choosing a product. Replacing sound hardware can be reasonable when it cannot provide the arrangement you need.
For a security upgrade, assess the door, strike and frame alongside the lock. A new cylinder cannot compensate for every weakness elsewhere. Our high-security lock upgrade page explains what to discuss without promising that any lock makes a property burglar-proof.
3. Check compatibility across the whole door list
Two locks that look similar may not share a compatible key system. Likewise, a desired replacement may not fit the existing door preparation. Tell Matrix which locks should use the same key and which should remain separate. Photographs and a door inventory can start the discussion, with final compatibility subject to assessment.
Property type matters too. A house, condominium unit and commercial storefront may have different responsible parties and hardware arrangements. Confirm shared-system, lease or building requirements with the appropriate owner or manager before agreeing to work.
4. Compare complete proposals, including mixed solutions
Ask which cylinders or hardware will change, which doors are included, how keys will be allocated and whether any door-condition issues remain outside the proposal. Rekeying is not always cheaper, and replacing every lock is not always necessary. The useful comparison is the complete scope for your property.
For example, a reliable rear-door lock might be suitable for rekeying while a worn front-door assembly needs replacement. A business may need new key access at selected doors while retaining separate access elsewhere. These are decision examples, not a diagnosis or guaranteed service outcome.
Bring a short door brief to the conversation
Count the doors, describe any faults, note whether you have working keys and explain who should have access afterwards. Include your Toronto area and property type so the discussion starts with useful information.

Questions about your next step
Does rekeying make the existing hardware stronger?
Rekeying changes the working key. It does not by itself upgrade the strength or condition of the remaining hardware, door, strike or frame.
Can I rekey some locks and replace others?
Yes, a mixed plan may be appropriate. The condition and compatibility of each lock, and whether doors need to share a key, should be assessed together.
Can I decide from photographs alone?
Photographs can help describe the existing hardware and prepare a discussion. They may not establish internal condition, dimensions or key-system compatibility, so an on-site check may still be needed.
