Rekeying vs Replacing Locks: Expert Guide for Canadian Homeowners

Paul Shelton

This in-depth guide explores the key differences between rekeying and replacing locks, helping Canadian homeowners decide which option best suits their needs for security, cost, and convenience.

Understanding the Basics: Rekeying vs Replacing Locks

When it comes to securing your home or business, one of the first decisions you may face is whether to rekey your locks or replace them entirely. Both options serve the purpose of enhancing your property’s security, but they come with different costs, benefits, and appropriate use cases. Knowing when to choose rekeying over a full lock change can save you time, money, and stress.

As a Canadian homeowner, understanding your lock options is essential, especially if you’re a new homeowner, have experienced a break-in, lost your keys, or are simply looking for a security upgrade. In this guide, we’ll break down everything you need to know so you can make the best decision for your home or business.

What Is Rekeying?

Rekeying locks involves changing the internal components of an existing lock so that it no longer works with the old key. A locksmith adjusts the pins and tumblers inside the lock cylinder to match a new key configuration. The process keeps the hardware intact while rendering previous keys useless.

When Should You Rekey?

  • You’ve just moved into a new home and want to ensure old keys no longer work.
  • You’ve lost a key or suspect someone unauthorized has access.
  • You want all locks in your house to work with a single key (keyed alike).
  • You need a quick and affordable security improvement.

Benefits of Rekeying

  • Cost-effective: Usually cheaper than a full lock replacement.
  • Fast and efficient: A professional can typically rekey multiple locks in under an hour.
  • Convenient: Allows for key change without replacing the lock hardware.

What Is Lock Replacement?

Replacing a lock means removing the entire lock mechanism—including the handle or deadbolt—and installing a brand-new one. This is often referred to as a lock change. It’s typically done when existing locks are damaged, outdated, or when a rekey isn’t sufficient for the desired level of security upgrade.

When Should You Replace Your Locks?

  • Your locks are old, worn, or malfunctioning.
  • You want to upgrade to smart locks or high-security models.
  • You’ve experienced a break-in and need stronger security measures.
  • You want to change the aesthetic or functionality of your door hardware.

Benefits of Lock Replacement

  • Enhanced security: Newer locks often come with advanced features and better resistance to tampering.
  • Modern functionality: Upgrade to smart locks, keypads, or biometric systems.
  • Aesthetic improvement: Match your locks to your home’s style.

Cost Comparison: Rekeying vs Replacing Locks in Canada

One of the most common questions we get at Fix Experts is, “Which option costs less?” While the answer depends on the lock type and the number of locks involved, we can offer a general breakdown for Canadian homeowners.

Rekeying Costs

Rekeying is usually the more budget-friendly option. In Canada, the average cost to rekey a standard residential lock ranges from $25 to $50 per lock. If you need to rekey multiple locks to use the same key, many locksmiths offer discounts for bulk services.

Additional fees may include:

  • Service call fee: $50–$100 depending on location and time of day
  • Emergency locksmith service fee for off-hours or urgent needs

If you need quick help, Fix Experts offers emergency locksmith services across Canada to assist with urgent lock rekeying or changes.

Lock Replacement Costs

Replacing locks tends to be more expensive due to the cost of new hardware. In Canada, replacing a standard lock typically costs between $80 and $250 per lock, depending on the brand and security level. High-security or smart locks can cost even more, upwards of $500 per unit installed.

Other cost factors include:

  • Labour and installation time
  • Custom door adjustments for new hardware
  • Disposal of old lock hardware

If you’re unsure which route to take, our residential locksmith services offer expert advice to help you make the most cost-effective and secure choice for your home.

Security Considerations for Canadian Homeowners

Whether you choose rekeying locks or full lock replacement, the ultimate goal is to improve your home’s security. Let’s look at how each option impacts your security profile and what Canadian homeowners should keep in mind.

How Rekeying Affects Security

Rekeying doesn’t change the lock’s physical security features. If your lock is already a Grade 1 or Grade 2 deadbolt (as per Canadian building codes), rekeying will maintain that standard. However, if your lock is low quality or worn out, rekeying won’t improve its strength or resistance to forced entry.

Good for:

  • Controlling access after a key is lost or stolen
  • Ensuring previous owners or tenants no longer have access
  • Cost-effective security improvement without upgrading hardware

How Replacing Locks Enhances Security

Replacing your locks allows for a full upgrade in security. New hardware can offer:

  • Anti-pick, anti-bump, and anti-drill features
  • Smart lock technology with remote access and alerts
  • Reinforced strike plates and bolts

For businesses and commercial properties, commercial locksmith services can include master key systems, access control, and heavy-duty locks designed to meet provincial safety regulations.

Practical Scenarios: What Should You Choose?

Let’s go over a few common scenarios to help you decide whether to rekey or replace your locks.

Scenario 1: You’re a New Homeowner

If you’ve just bought a home in Canada, it’s wise to update your locks. You don’t know how many copies of the old keys exist or who has them. In many cases, rekeying locks is sufficient and cost-effective. However, if the locks are old or mismatched, a full lock change may be the better solution.

Scenario 2: You’ve Had a Break-In

After a break-in, your priority should be safety. If the intruder forced the lock or damaged it, you’ll need a lock replacement. Upgrading to a high-security deadbolt or a smart lock can provide peace of mind and better protection going forward.

Scenario 3: You Lost Your Keys

Losing your keys can be stressful. If you’re worried they could fall into the wrong hands, rekeying locks is a fast and affordable way to regain control. You won’t need to replace the hardware unless it’s outdated or compromised.

Scenario 4: You Want to Upgrade to Smart Locks

Smart locks offer modern convenience, such as keyless entry and remote access. If that’s what you’re looking for, you’ll need a full lock change. These locks often require Wi-Fi or Bluetooth connectivity and are ideal for tech-savvy homeowners or landlords managing multiple properties.

Scenario 5: You’re a Landlord Between Tenants

It’s your responsibility to ensure each new tenant has exclusive access. Rekeying is a common and cost-effective practice for landlords. However, if locks are damaged or if you’re upgrading security for building compliance, lock replacement may be more appropriate.

Durability and Lock Maintenance

No matter which option you choose, ongoing lock maintenance is important for long-term performance and security. Here’s how to keep your locks in top shape:

Regular Lock Maintenance Tips

  • Lubricate locks annually with graphite-based lubricant
  • Check for loose screws or misaligned strike plates
  • Clean your locks and keys to prevent debris buildup
  • Test keys regularly to ensure smooth operation

If you’re dealing with a sticky lock or worn key, a quick key change or rekeying might solve the problem without needing a full lock replacement.

When to Call a Professional

Some issues are best left to the experts. If your lock is jamming, spinning, or showing signs of tampering, it’s time to contact a certified locksmith. Fix Experts offers professional car locksmith and home locksmith services for all kinds of lock issues, including emergency situations.

Long-Term Value: Rekeying and Replacement Over Time

While the upfront cost and immediate needs often drive the decision between rekeying and lock replacement, it’s wise to also consider the long-term value. Choosing the right lock solution now can save you money and hassle in the future, especially when it comes to ongoing lock maintenance, security upgrades, and property management.

Longevity of Rekeyed Locks

Rekeyed locks can last just as long as new ones—assuming the existing hardware is still in good condition. If your locks are high quality and well-maintained, rekeying them can extend their useful life by several years. However, if the locks are already showing signs of wear, rekeying might just delay the inevitable need for a full lock change.

Things to Watch For:

  • Difficulty turning the key even after rekeying
  • Visible rust or corrosion on the lock body
  • Loose or misaligned mechanisms

Durability of New Lock Hardware

Replacing your locks with new, high-quality models often brings better long-term value. New locks typically come with warranties, improved materials, and modern security features designed to resist wear and tampering. This is especially important in Canada, where extreme weather can affect older lock hardware.

Choosing locks rated according to Canadian building standards—such as ANSI Grade 1 or 2—ensures your home or business remains secure year-round. For added peace of mind, professional locksmith services like Fix Experts can recommend the best lock brands and install them to meet provincial codes.

Custom Solutions for Unique Lock Needs

Not every lock situation fits neatly into a “rekey or replace” decision. Many Canadian homeowners and property managers face unique challenges that require customized solutions. Whether you’re managing multiple units, dealing with antique locks, or integrating smart home systems, a one-size-fits-all approach just doesn’t work.

Multi-Unit Properties and Master Key Systems

For landlords or owners of duplexes, triplexes, or apartment buildings, rekeying can be used to create a master key system. This allows one master key to open all units (for maintenance or emergencies), while individual tenants have keys that only work for their own doors.

This approach is both cost-effective and efficient, especially when paired with commercial locksmith services tailored to multi-unit residential buildings. If security requirements increase or tenant turnover is high, periodic rekeying can be part of your lock maintenance plan.

Upgrading Older Homes with Antique Locks

Older Canadian homes may feature antique or vintage locks that are no longer manufactured. In these cases, rekeying might not be possible due to outdated mechanisms or worn parts. A full lock replacement can preserve the charm of your home while improving safety.

Fix Experts can assess your existing locks and recommend modern replacements that match the style of heritage homes while meeting today’s security standards. This ensures you don’t sacrifice safety for aesthetics.

Integrating Smart Home and Security Systems

Modern Canadian homeowners are increasingly turning to smart home technology. If you’re installing a home security system, smart lights, or even remote-controlled thermostats, upgrading to smart locks is a natural next step.

Since most smart locks require compatible hardware, a full lock change is necessary. These systems allow you to:

  • Control access remotely through your smartphone
  • Track who enters and exits your home
  • Set temporary codes for guests, cleaners, or deliveries

Our residential locksmith services can assist with recommending and installing smart locks that integrate seamlessly into your existing setup while following Canadian privacy and data standards.

DIY vs Professional Lock Services in Canada

Some homeowners consider doing their own rekeying or lock replacement to save on costs. While DIY may work in some cases, there are important considerations to keep in mind—especially when it comes to proper installation, security, and warranty coverage.

When DIY Might Be Enough

If you’re handy and dealing with a basic interior door lock, you might be able to manage a simple rekey or lock swap using kits available at Canadian hardware stores. However, this isn’t recommended for exterior doors, smart locks, or high-security systems.

Risks of DIY Lock Work:

  • Incorrect installation can compromise security
  • Lack of proper tools or instructions can damage the lock
  • May void manufacturer warranties

Why Choose a Professional Locksmith

Hiring a certified locksmith offers peace of mind, expert guidance, and guaranteed results. Fix Experts provides emergency locksmith services across Canada, so you’re covered whether you need a late-night lockout solution or a full security upgrade.

Professional locksmiths can:

  • Assess your specific security needs
  • Recommend the best lock options for your budget and lifestyle
  • Ensure code-compliant installation that lasts
  • Provide custom solutions for unique properties

If you need expert locksmith help, Fix Experts is here to help homeowners and business owners make informed, secure decisions.

Environmental and Aesthetic Considerations

While security and cost are usually top of mind, many Canadian homeowners are also thinking about the environmental and visual impact of their choices. Whether you’re eco-conscious or looking to boost curb appeal, your decision between rekeying and replacing your locks can have broader implications.

Eco-Friendly Security Options

Rekeying is the greener option because it reuses the existing lock hardware, reducing waste. If you’re making eco-conscious upgrades to your home—like switching to energy-efficient appliances or sustainable materials—rekeying aligns well with those values.

On the other hand, if your locks are beyond repair, choosing high-quality, long-lasting locks made from recyclable materials helps minimize future waste. Many modern lock manufacturers now offer eco-friendly options, which our residential locksmith services can help source and install.

Boosting Curb Appeal with New Locks

Lock replacement allows you to refresh the look of your doors. This is especially beneficial if you’re planning to sell your home or simply want to improve its exterior appearance. Available in various finishes—from matte black to brushed nickel—new locks can complement your home’s architecture and style.

In addition to aesthetics, replacing old or mismatched locks can send a strong message about the care and upkeep of your property. It shows potential buyers or tenants that security hasn’t been overlooked.

Making the Right Choice for Your Home or Business

Ultimately, whether you choose rekeying or lock replacement depends on a few key questions:

  • Is your current lock hardware still in good shape?
  • Do you want to improve aesthetics or functionality?
  • Is cost a major concern, or are you investing in long-term security?
  • Do you need advanced features like smart access or master key systems?

Our Recommendation

If your locks are relatively new and undamaged, rekeying locks is often the most cost-effective and efficient option. It’s perfect for new homeowners, landlords between tenants, or anyone needing a fast key change.

However, if you’re looking for a security upgrade, have old or malfunctioning locks, or want to modernize your home, a full lock change is the smarter long-term investment. It offers better protection, added convenience, and often a sleek new look.

Conclusion: Secure Your Property with Confidence

Both rekeying and replacing your locks offer unique advantages, depending on your needs, budget, and goals. For Canadians concerned about safety, security, and peace of mind, understanding the difference is key to making the right decision. Whether you’re rekeying to cut costs or replacing locks for a full upgrade, you can count on Fix Experts for expert advice and flawless service.

Replacing locks is more expensive, ranging from $80 to $250 per lock, depending on the type. Smart or high-security locks can exceed $500.

How long does it take to rekey or replace locks?

Both services can often be completed in a single visit.
What are signs that I should replace my locks instead of rekeying?
You should replace your locks if they’re old, worn out, damaged during a break-in, or lack modern security features. Replacing is also ideal when upgrading to smart locks or changing the look and feel of your door hardware. Fix Experts recommends replacements when rekeying won’t meet your security or functional needs.
Should I rekey or replace my locks when I move into a new home?
If you’re a new homeowner in Canada, rekeying is often a safe and cost-effective choice since it prevents old key access without replacing hardware.

How often should I maintain or check my home locks?
It’s good practice to maintain your locks annually. This includes lubricating with a graphite-based product, checking for wear, tightening screws, and ensuring keys operate smoothly. Regular upkeep extends your locks’ lifespan and ensures your home remains secure. Fix Experts also provides professional lock inspections for added peace of mind.
Can I rekey my locks myself or do I need a professional?
While DIY rekey kits are available, proper rekeying requires knowledge of lock mechanisms and specialized tools. For reliable security, it’s best to hire a certified locksmith like Fix Experts. Our professionals ensure all locks are rekeyed correctly and securely, saving you time and reducing the risk of improperly secured doors.
