Why You Should Rekey Your Locks: Key Reasons for Better Security 🔑
When it comes to protecting your home, business, or rental property in Melbourne, ensuring that only authorized individuals have access to your locks is crucial. Rekeying is a cost-effective way to enhance security without replacing your entire lock system. But why is it necessary? Let’s explore some common situations where rekeying is the best option.
- Lost or Stolen Keys – Prevent Unauthorized Access 🚨
🔵 Imagine losing your house keys in a public place—there’s no way to know who might have picked them up. Instead of living with uncertainty, rekeying ensures that the lost keys no longer work, instantly improving security.
✅ Why it’s important:
- Reduces the risk of break-ins 🔒
- Ensures peace of mind for homeowners & businesses 🏠🏢
- A quicker and more affordable solution compared to replacing locks
📌 Pro Tip: If your keys are stolen, act fast! Many locksmiths in Melbourne offer emergency rekeying services to secure your property ASAP.
- Moving into a New Property – Who Else Has the Keys? 🏡
🟢 Whether you’re a homebuyer, renter, or business owner, it’s impossible to know how many key copies exist. Previous tenants, real estate agents, contractors, or even neighbors may still have access to your locks.
💡 Solution: Rekeying ensures you’re the only one with working keys, eliminating the risk of unauthorized entry.
✅ Ideal for:
- Homeowners moving into a new house 🏠
- Landlords after tenant turnover 🏢
- Business owners securing new commercial spaces
📌 Did You Know? Some insurance companies may deny burglary claims if there’s no sign of forced entry. Rekeying locks strengthens security and can prevent such issues.
- Tenant or Employee Turnover – Maintain Key Control 🔑
🟡 If you’re a landlord or run a business, ensuring that former tenants or employees can’t access your property is a top priority.
Residential Properties 🏠:
- Renters often make duplicate keys—rekey locks between tenants to avoid unauthorized access.
- Rekeying is cheaper than changing locks for every new occupant.
Commercial Properties 🏢:
- Employees with access to offices, warehouses, or storage units may keep keys after leaving.
- Rekeying ensures that only current staff members have access.
- Master Key Systems allow controlled access for different employees. 🔴
📌 Melbourne landlords & business owners: Stay compliant with security regulations and protect your assets with routine rekeying.
- Enhancing Security on a Budget – Affordable & Effective 💰
🔵 Security threats aren’t always external—sometimes, updating your locks is a proactive measure to maintain safety.
✅ Why rekeying is the best option:
- More affordable than full lock replacement
- Works on most residential & commercial locks
- Can be done in under 30 minutes per lock
📌 Budget Tip: If you have multiple locks to rekey, some locksmiths offer discounted package deals.
- Rekeying for Master Key Systems – Simplify Access Control 🏢
🔴 Master key systems are essential for businesses, apartment buildings, and hotels in Melbourne.
💡 How it works:
- One key opens multiple locks while allowing different access levels.
- Perfect for landlords, property managers, and office buildings.
- Rekeying lets you update or customize key access as needed.
Rekeying Locks in Melbourne: Cost Estimates
Average Rekeying Costs – Residential vs Commercial
Locksmith Service Comparison (Residential vs. Commercial - Melbourne)
| Service | Residential (Melbourne) | Commercial (Melbourne) |
|---|---|---|
| Rekey single lock (standard hours) |
$35 – $60 per lock (on-site service) If you remove the lock and take it to a locksmith shop, cost can be as low as $20 – $30 per lock. |
$50 – $80 per lock for standard commercial locks (similar process as residential). Complex commercial locks (e.g. storeroom or mortise locks) fall in the higher end of this range. |
| Rekey multiple locks (e.g. 3 locks) |
~ $30 – $50 per lock when rekeying several at once (total ~$100 – $150 for 3 locks). Many locksmiths charge a single call-out fee plus a per-lock rate, so doing multiple locks in one visit is cost-effective. |
Similar per-lock rates (~ $50± each). Larger jobs may get volume discounts. For example, rekeying 3 standard locks might roughly cost $150 – $250 in total, since one service call covers all locks (lower average per lock). |
| Emergency rekey (after-hours) |
+ $100 – $300 surcharge on top of regular rates for 24/7 emergency service. (Locksmiths charge higher call-out fees late at night or on weekends, e.g. around $150–$200 late evening, rising to ~$300 after midnight.) |
+ $100 – $300 after-hours fee in addition to standard rekey costs. Commercial emergency services are typically in the same surcharge range as residential (often around $150+ for night calls). |
| High-security locks |
High-security or restricted key locks cost more to rekey – often at the upper end (e.g. $60+ per lock). These locks use specialized pins/keys, so new restricted keys (~ $20–$35 each) may add to the total. |
Higher cost per lock than standard. Rekeying restricted/high-security locks can be more labor-intensive and may require purchasing new restricted keys, pushing costs above $60 per lock. (Installing brand-new high-security locks can range $100–$400 each, so rekeying them is cheaper but still above a standard lock’s cost.) |
| Master key system rekey/setup |
N/A – Master key systems are uncommon in single homes (aside from simple “keyed alike” locks). Standard residential rekeying involves making all locks use one key if desired (usually included at no extra charge if locks are compatible). |
$150 – $600 for master key system rekey or setup (small business systems). This cost range covers designing the master system and rekeying multiple cylinders. Simple master-keying (one master key + individual keys) might be at the lower end, while large or high-security master systems cost more. |

What Determines Rekeying Costs? Key Factors That Impact Pricing
Several key factors influence the cost of rekeying locks in Melbourne:
- Lock Type & Complexity: The type of lock matters. Simple pin-tumbler locks are cheaper to rekey, while high-security or commercial-grade locks may cost more due to specialized parts or complexity. For example, upgrading to a high-security lock often requires a full replacement rather than a rekey, and restricted key systems involve extra expenses for patented keys.
- Number of Locks: Rekeying multiple locks in one visit will increase the total cost, but many locksmiths charge a single call-out and a lower per-lock fee for additional locks. This means the cost per lock drops when doing several at once, making it economical to rekey an entire home or business in one go.
- Time of Service: After-hours or emergency service calls significantly increase the price. Rekeying done at night, on weekends, or on holidays will include higher call-out fees (often 1.5× to 3× the normal rate). For instance, a rekey job during business hours might incur a $110 call-out, whereas the same job at midnight could incur a ~$300 call-out fee
- Locksmith’s Experience/Reputation: Highly experienced or reputable locksmiths may charge a premium for their expertise. A Master Locksmith or specialist might quote slightly higher rates, but they often provide quality service and may handle complex rekeying (e.g. master key systems) more efficiently.
- Urgency of Service: If you need immediate service (even during normal hours), some locksmiths charge extra for prioritizing your job. “Urgent” same-day requests can incur a surcharge, especially if the locksmith must reschedule other work.
- Travel and Location: Distance can affect cost – if you are located far from the locksmith’s base, a higher travel fee may apply. Hiring a nearby locksmith can reduce call-out charges

How to Choose the Best Locksmith for Rekeying in Melbourne 🔑
Finding a reliable locksmith in Melbourne for rekeying services is essential to ensure security, affordability, and quality workmanship. With many locksmiths offering similar services, how do you choose the right one? Follow these key factors to make an informed decision.
- Check Licensing & Certification 📜
🟢 In Australia, professional locksmiths should be licensed and registered under local security regulations. This ensures they meet industry standards and legal requirements. Look for locksmiths who are members of the Master Locksmiths Association of Australasia (MLAA), as this certification indicates credibility and expertise.
- Look at Reviews & Customer Ratings ⭐
🟡 Always check Google reviews, social media feedback, and customer testimonials. A trustworthy locksmith will have consistent positive ratings, particularly in areas like response time, pricing transparency, and service quality. Avoid locksmiths with excessive complaints about hidden fees or poor workmanship.
📌 Pro Tip: Search for locksmiths with a strong presence in Melbourne suburbs—local experts tend to offer faster, more affordable service.
- Compare Pricing & Get Upfront Quotes 💰
🔵 The cost of rekeying locks in Melbourne varies, but a professional locksmith should offer a clear, itemized quote before starting work.
✅ Red Flags to Watch For:
- Extremely low pricing (could indicate hidden charges or poor quality).
- No written estimate—always request one before the job begins.
- Locksmiths refusing to disclose a call-out fee or per-lock rekeying charge.
- Ensure They Offer Emergency & Mobile Services 🚨
🔴 If you ever need a 24/7 emergency locksmith, make sure they have fast response times and mobile rekeying services. Many Melbourne locksmiths offer on-site rekeying, which saves you the hassle of removing locks and taking them to a shop.
📌 Check Their Response Time: Reliable locksmiths can typically reach you within 30–60 minutes for urgent cases.
- Experience & Specialization in Rekeying 🔐
Not all locksmiths specialize in residential and commercial rekeying. Ensure the locksmith you choose has experience with:
✔ Master key systems (for offices, rental properties, and apartment complexes).
✔ High-security lock rekeying (restricted key systems, digital locks).
✔ Smart lock integration (if you’re upgrading to an electronic lock).
