Rekeying vs. Replacing Locks in Quebec: Cost, Security & Options

Deciding between rekeying and replacing your home's locks? Rekeying is the budget-friendly choice for changing access, while replacing allows for security upgrades and style changes, especially important given Quebec's harsh climate.
Lost your keys, moving into a new home, or just seeking better peace of mind for your Quebec property? You're faced with a common question: should you rekey your existing locks or replace them entirely? The short answer for most homeowners is that rekeying is significantly more affordable, but replacement offers opportunities for enhanced security and style.
Rekeying (Recléage): When It Makes Sense
Rekeying, or "recléage" in French, changes the internal pin configuration of your existing lock so that only a new key will operate it. Your old keys become useless. This is your go-to option when your current locks are in good working order, visually appealing, and you're satisfied with their security level, but you need to control who has access.
Think about it for situations like:
- Moving into a new house or duplex in Montreal or Quebec City.
- A tenant moves out, and you need to secure your rental unit.
- You've lost a key, and you're worried it might fall into the wrong hands.
- You want one master key for several doors, consolidating that jumble of keys on your keyring.
The Cost: Rekeying is budget-friendly. You can expect to pay between $20 to $50 CAD per lock, plus a service call fee for a qualified locksmith. Rekeying an entire house, say six deadbolts, will likely cost a few hundred dollars.

Replacing Locks: An Upgrade Opportunity
Replacing locks means removing the old hardware and installing completely new units. This is a more involved and often more expensive process, but it's the right choice when your goals go beyond just changing access.
Consider replacing your locks if:
- Your current locks are old, worn out, corroded, or visibly damaged. Quebec's harsh winters and humid summers, with their relentless freeze-thaw cycles, can really take a toll on exterior hardware, leading to seized mechanisms or accelerated wear.
- You want to upgrade your home's security with higher-grade locks, anti-pick features, or modern smart lock technology.
- You're updating your home's aesthetic and want a new style or finish for your hardware.
- Your existing locks are simply poor quality or offer minimal protection.
The Cost: Replacing locks comes at a higher price point. The hardware alone for a quality smart key deadbolt can run you $60-$70 CAD, not including installation. A full replacement for multiple doors, including professional installation, will be a substantially larger investment than rekeying.

Quebec Specifics to Keep in Mind
When hiring a professional for either service, remember that while the RBQ (Régie du bâtiment du Québec) governs general contractors, locksmiths in Quebec are not provincially regulated specifically for lock work. However, any locksmith performing certain security-related tasks must hold a permit from the Bureau de la sécurité privée (BSP). Always ensure you're hiring a reputable local professional.
Making Your Decision: A Quick Checklist
- Security Level: Are you happy with your current lock's security, or do you need an upgrade? (Rekey = same security; Replace = potential for upgrade)
- Condition & Appearance: Are your existing locks looking tired, damaged, or malfunctioning? (Rekey = good condition; Replace = old/damaged)
- Budget: How much are you willing to spend? (Rekey = $20-$50/lock; Replace = higher hardware + installation cost)
- Convenience: Do you want all your exterior doors to use the same key? Both rekeying and replacing can achieve this, but rekeying is usually the cheaper route for consolidation.
For Quebec homeowners, especially those dealing with the wear and tear of our unique climate, a professional assessment is invaluable. Whether you need a simple rekeying to secure your new duplex or a full lock upgrade for your bungalow, a local expert can guide you to the best solution.
