Smart Lock vs Traditional Lock – Best Choice for Your Property

Choosing the right lock for your home or business is more than just picking a key and a door handle. The lock you install sets the foundation for peace of mind, day in and day out. Whether you manage a family home, a short-let property, or a commercial premises, you want a system that you can rely on.

At Page Security, we have served customers across London & the South East for over 15 years, offering both traditional lock upgrades and modern access control solutions. Our goal here is simple: to compare smart locks with traditional mechanical locks, highlight the key differences, and help you decide which fits your property and access needs best.

By the end of this guide you should have a clear sense of how each solution works, what advantages they deliver, and how to make the right choice for your situation.

The best choice depends on your door type, budget, user profile and future access needs.

Did you know one lock’s fitting can determine whether your insurance claim is valid?

1) Understanding Traditional Locks

What Are Traditional Locks?

Traditional locks rely on purely mechanical components. These devices include common types such as five-lever mortice deadlocks, euro-cylinder locks (often fitted in uPVC and composite doors), rim locks and multipoint locking systems. They operate via a physical key which inserts into the lock, aligns internal pins or levers, and allows a bolt or locking mechanism to engage or disengage.

Advantages of Traditional Locks

Reliable and time-tested: mechanical locks have been in use for decades and are well understood.
No dependence on power supply, batteries or network connectivity: the mechanism works so long as the door and lock are in good condition.
Widely accepted by insurers provided the lock meets recognised standards and is properly fitted.
Generally lower upfront cost than high-tech alternatives and easy to service locally.

Limitations of Traditional Locks

Lost or duplicated keys can present a security risk and managing keys can be cumbersome.
There is no remote control, no log of who entered and when, and no temporary access codes built-in.
Older or poorly fitted locks may not meet current insurance or forced-entry resistance standards.

Mini Checklist – Is your lock due for an upgrade?

Door and frame have not been inspected for several years.
The lock feels loose, the key is harder to turn or locks occasionally jam.
You have lost one or more keys and are unsure who has copies.
The existing hardware is legacy or does not carry a recognised standard.
You have started letting the property or expect more users than before.

In many homes and businesses we serve at Page Security a high-quality traditional lock remains the right choice. It is often the most cost-effective way to meet insurer requirements and provide dependable security.

2) Understanding Smart Locks

What Are Smart Locks?

Smart locks marry robust mechanical locking hardware with digital or electronic access methods. They may be operated by smartphone apps, keypad entry codes, RFID key-fobs or even biometric systems such as fingerprint readers. Some are stand-alone retrofits; others integrate into home automation or access control systems.

Advantages of Smart Locks

Keyless entry: no physical key needed for authorised users, easier for families, tenants or trades.
Remote management: you can grant access from the office, check status while away or send a temporary code to a visitor.
Integration: in buildings where we install access-control or door-entry systems at Page Security, smart locks sit neatly alongside alarms, intercoms and camera access.
Ideal for multi-user properties, rental homes, commercial buildings or where convenience is a key factor.

Considerations Before You Install

Upfront cost is typically higher than a traditional mechanical lock.
Batteries must be monitored and ultimately replaced; some systems require network or Wi-Fi access.
No matter how smart the exterior features, the underlying mechanical lock must be installed correctly and meet the insurer’s standard – for instance on wooden doors many insurers still refer to the BS 3621 standard.
Professional installation is key – incorrect alignment or weak door/frame can nullify benefits. At Page Security we always assess door and frame condition before recommending a smart system.

Smart locks offer compelling features but are not a universal solution. The decision depends on your property type, user needs and budget.

3) Smart vs Traditional: A Side-by-Side Comparison

Comparison Table

Feature	Traditional Lock	Smart Lock
Operation	Physical key	Smartphone, keypad, fob or biometric
Power requirement	None	Battery or mains power
Security	Proven mechanical strength	Mechanical strength plus digital control
Insurance compliance	Commonly accepted when approved hardware fitted	Accepted only if mechanical component meets standard
Cost	Lower initial cost, minimal upkeep	Higher initial cost, ongoing maintenance
Convenience	Familiar and simple	Keyless entry, remote access, guest codes
Maintenance	Occasional servicing	Battery changes, firmware updates, checks
Best suited for	Simplicity and reliability	Flexibility and multi-user access

When you compare the two types side-by-side the picture becomes clear: both can secure your property effectively when fitted correctly. A traditional lock can deliver excellent protection if it meets the insurer’s standard, the door and frame are in good condition and the installation is professional. Meanwhile a smart lock adds convenience, control and flexibility – but it also introduces more moving parts and requires ongoing attention.

At Page Security we take the view that neither option is inherently superior – the best choice is the one that fits your property, usage and budget.

4) When to Choose a Traditional Lock

Traditional mechanical locks excel in situations where simplicity, reliability and cost-efficiency matter most. If your property has heritage doors, older frames, or operates in an area where connectivity is unreliable, then a high-quality traditional lock is often the right choice. It is especially suitable if the number of users is stable, guest or tenant access is limited and your priority is durability rather than remote features.

When upgrading to meet insurer expectations it is important to fit a lock that is insurance-approved British Standard and correctly installed. At Page Security we supply and fit such locks, and professionals can check the condition of the door and frame to ensure the hardware will perform as required.

Top Tip: Upgrading a cylinder or mortice lock to a recognised standard model may significantly improve your security without changing the door. This is often the most cost-efficient solution for homeowners and small businesses alike.

5) When to Choose a Smart Lock

If your property handles multiple users, frequent short-term access (such as holiday lets) or you are managing a business entrance or multi-unit building, a smart lock may be the better fit. Smart solutions shine when convenience, remote access control and flexible access for users are key requirements.

For commercial or multi-occupancy buildings we install access control and door-entry systems that integrate smart locks seamlessly. This allows you to issue time-limited codes, check logs of entries, and manage access remotely – all of which can contribute to better security and user management.

Before you buy – Checklist

Confirm the lock is compatible with your door type and frame.
Ensure there is a mechanical override (key fallback) in case of battery or network failure.
Verify your insurer recognises the smart lock and the mechanical component meets the standard.
Identify who will install, service and maintain the system – professional fitting is critical.

When installed and managed correctly, smart locks give you modern functionality while retaining solid security.

6) What to Consider Before You Decide

Property and Usage

Realise how the property is used. Is it a single family home, a short-let rental, or a business with many users? How many doors require access, how many people use them and from where? The door material and frame condition also affect what hardware you can fit.

Insurance and Standards

Many insurance policies are explicit about the locks you must have to maintain cover. On external wooden doors, for example, the BS 3621 standard is often cited. In all cases fitting a lock described as an insurance-approved British Standard is a safe starting point. At Page Security we always check that any lock we supply will satisfy insurer requirements.

Budget and Lifecycle Cost

Look beyond the initial purchase price. Smart locks may have higher up-front cost, but traditional locks may avoid ongoing maintenance. Conversely, a cheap mechanical lock that does not meet standard may cost you dearly if you suffer a break-in.

Installation and Aftercare

Even the best lock will underperform if the door or frame is weak, or if installation is poor. Professional fitting ensures correct alignment, strong fixing, correct strike plate and full engagement of the bolt. At Page Security we survey the door and frame before installation and offer aftercare to ensure performance remains high.

Pro Tip: No matter how good the lock is, if the door frame fails the value is lost. Always evaluate the frame condition as part of your upgrade.

7) Choosing with Confidence

Both lock types are capable of securing your property when matched with the right door, frame and professional installation. At Page Security we offer a consultation and survey service to help you decide which solution fits best, and we are available 24-hours for emergency support if you ever need it.

Whether your priority is straightforward reliability or flexible user access and remote control, we will guide you through the options. If you manage a home in London or the South East, let us help you establish the best lock solution for your property and ensure it is fitted to the highest standard.

Conclusion: Smart Lock vs Traditional Lock

There is no single lock type that works best for every situation. A traditional mechanical lock offers proven reliability, lower cost and widespread acceptance by insurers. A smart lock offers access control, convenience and modern functionality.

The best option for your property depends on your door and frame, number of users, budget and long-term needs.

Smart Lock vs Traditional Lock: Frequently Asked Questions

1. Are smart locks as secure as traditional locks?

Yes, when installed properly and used with high-quality mechanical components, smart locks can be just as secure as traditional locks. The electronic features simply add convenience. The mechanical part of any smart lock should still meet insurance-approved British Standard requirements to ensure full protection.

2. Do smart locks work without Wi-Fi or power?

Many models include battery backup or manual key override, allowing operation even if the power or network connection fails. At Page Security we always recommend choosing a smart lock that includes a reliable fallback such as a physical key or an emergency power supply.

3. Will my home insurance cover smart locks?

Most insurers will accept smart locks as long as the mechanical locking component meets the required British Standard, such as BS 3621 for wooden doors. Always check your individual policy wording, and we can advise you during installation to ensure compliance.

4. Are traditional locks still a good choice?

Absolutely. Traditional locks remain the most common and trusted option for many properties. When installed correctly and upgraded to meet the latest standards, they provide long-term reliability and are widely accepted by insurers. At Page Security we still fit and service thousands of traditional locks every year.

5. How long do smart lock batteries last?

Battery life depends on usage and model but generally ranges from six months to two years. Many systems alert you well before power runs low. We advise checking batteries as part of your regular home maintenance routine.

6. Can a smart lock be hacked?

Any connected device can carry some digital risk, but reputable brands use encryption and security protocols to reduce the likelihood of compromise. A professional installation and regular firmware updates are the best way to keep systems secure.

7. How often should I replace or upgrade my locks?

It’s sensible to review your locks every five to seven years or sooner if you experience difficulty turning the key, notice visible wear, or have moved into a new property. If you lose keys or have reason to believe they’ve been copied, replacing the lock immediately is the safest step.

8. Can Page Security install both traditional and smart locks?

Yes. We supply, install and service both types across London and the South East. Whether you need a British Standard mortice lock, a smart cylinder, or an integrated access control system, our engineers will fit the correct lock for your property.

9. Do smart locks need professional installation?

Professional installation ensures the lock is correctly aligned, the door and frame are properly reinforced, and all digital features work as intended. Poor DIY installation can cause faults or void insurance. Our locksmiths check every detail to make sure the system performs safely and reliably.

10. What’s the best lock for my property?

There isn’t a single answer. The right solution depends on the property type, number of users, connectivity, and your budget. Our team can survey your doors, advise on insurance compliance, and recommend the most suitable option for lasting security and convenience.
