Securing Access Hardware with Electric and Digital Locks
As buildings evolve to meet modern standards of safety, convenience, and design, so too does the hardware that protects them. From residential entrances to commercial facilities and multi-occupancy dwellings, access control has become smarter, stronger, and more secure.
At SDS London, we understand that true door security isn’t just about the lock you can see — it’s about how all the components work together behind the scenes. In this guide, we’ll explore how electric locks, digital locks, and tamper-proof fixings combine to create robust, future-ready access control solutions.
Understanding Modern Locking Systems
Traditional mechanical locks still have their place, but the demand for convenience, remote management, and data-driven control has pushed the industry towards electronic and digital technologies.
Electric Locks
Electric locks use a power source — often low voltage — to control the locking mechanism. They can be triggered by a range of inputs: keypads, card readers, key fobs, intercom systems, or even smartphone apps. Common types include:
Electric Strike Locks: Replace a standard strike plate and release the latch when power is applied (fail-secure) or removed (fail-safe). Ideal for access-controlled office doors and communal entrances.
Magnetic Locks (Maglocks): Use electromagnets to hold the door closed with significant force — sometimes up to 600kg — until power or an authorised signal releases it. Often used in high-traffic or secure environments.
Electric Bolts and Shear Locks: Offer a discreet, high-security locking method often found in glass doors, sliding systems, or architectural entrances.
The advantage of electric locks lies in their ability to integrate seamlessly with access control systems, allowing administrators to monitor and manage entry points remotely.
Digital Locks
Digital locks, while sometimes used interchangeably with electric locks, are distinct. They typically combine mechanical locking with digital authentication — using a keypad, card, or biometric input — and can function independently from a central system.
There are two main types:
Standalone Digital Locks – Battery-powered units that require a code or fob, ideal for small offices, internal doors, or shared workspaces.
Networked or Smart Digital Locks – Connected to Wi-Fi or Bluetooth for smartphone control, user management, and audit trails.
These systems remove the need for traditional keys, reducing the risk of lost or copied keys compromising security.
The Benefits of Electric and Digital Locks
Keyless Entry – No more mechanical key management.
Access Control – Limit entry by user, time, or department.
Audit Trails – Digital systems can log who entered and when.
Integration – Can connect with alarms, CCTV, and fire systems.
Design Flexibility – Available in architectural finishes to complement interior schemes.
For many modern projects, combining the reliability of mechanical locking with the intelligence of digital control provides the best of both worlds.
The Role of Tamper-Proof Fixings
No locking system is complete without secure fixings. A lock’s strength is only as reliable as its installation — and that’s where tamper-proof screws and fixings make all the difference.
Why Fixings Matter
Every door, lock, or hinge is held in place by screws or bolts. If those fixings can be easily removed, the entire system’s security is compromised. Tamper-proof fixings — also known as security screws — are designed to resist unauthorised removal or interference.
Common Types of Tamper-Resistant Fixings
Pin-Torx (Star) Screws – Require a matching driver with a centre pin recess.
One-Way Screws – Can be installed with a standard driver but cannot be easily removed.
Clutch-Head Screws – Turn in one direction only, preventing reverse unscrewing.
Shear Bolts – Heads snap off during installation, leaving a smooth, non-grippable surface.
Security Nuts and Bolts – Feature unique drive shapes that require specialist tools.
At SDS London, we supply a range of tamper-proof fixings suitable for both external and internal applications, ideal for use with locks, handles, and other access control components.
Applications for Tamper-Proof Fixings
Public Buildings – To prevent vandalism or unauthorised disassembly.
Schools and Hospitals – Where safety and restricted access are essential.
Multi-Occupancy Flats – To protect communal entry systems.
Commercial Premises – For protecting exposed hardware and signage.
By specifying the right fixings alongside your chosen locks, you create a layered approach to security — protecting both the entry point and the hardware itself.
How Electric and Digital Locks Integrate
Electric and digital locks are not mutually exclusive; in fact, many access systems combine the two for optimal control and reliability.
Integration with Access Control Systems
Modern electric and digital locks can form part of a wider access ecosystem. This could include:
Proximity Card Systems – RFID readers linked to an electric strike.
Biometric Readers – Fingerprint or facial recognition controlling a digital latch.
Building Management Systems (BMS) – Integrated control for doors, alarms, and CCTV.
For example, a main entrance might use a maglock released by a keypad or card reader, while internal offices feature standalone digital locks for selective entry.
This layered approach ensures both convenience and compliance — essential in environments where security standards must meet regulations such as BS EN 14846 (electrically controlled locks) or BS EN 12209 (mechanical locks).
Power and Safety Considerations
When installing electric locks, consider how the system behaves in a power failure.
Fail-safe locks unlock when power is lost, suitable for emergency exit routes.
Fail-secure locks remain locked, maintaining security but requiring backup access for emergencies.
Battery back-up units or uninterruptible power supplies (UPS) can provide continuity during outages.
Best Practices for Access Hardware Installation
Even the most advanced lock can be ineffective if installed incorrectly. Professional installation, correct fixings, and adherence to standards are vital.
1. Choose the Right Lock for the Door Type
Different materials require different approaches:
Timber Doors – Typically accommodate most electric strikes and mortice locks.
Metal Doors – May require purpose-built electric locks or reinforced fixings.
Glass Doors – Often use shear locks or surface-mounted maglocks to maintain aesthetics.
2. Specify Correct Fixings
Match fixings to both the substrate and the security level required. For example, high-traffic entrance doors benefit from shear nuts or pin-Torx screws to prevent tampering.
3. Ensure Power Compatibility
Check voltage and current requirements before wiring electric hardware. Incorrect power supply can lead to overheating, lock failure, or reduced lifespan.
4. Integrate Early in the Design Process
Electric and digital systems are most effective when specified during the design phase — allowing proper cable routing, power provision, and finish matching.
5. Comply with Fire and Safety Standards
Locks on fire-rated doors must be compatible with escape route requirements. Always confirm compliance with BS EN 179 or BS EN 1125 (emergency exit devices) when using powered locks on designated escape doors.
Maintenance and Security Tips
Once installed, consistent maintenance ensures long-term reliability and security performance.
1. Regular Testing
Electric and digital locks should be tested at least quarterly to ensure functionality, battery health, and signal responsiveness.
2. Clean and Lubricate
Use non-corrosive lubricants on mechanical components and keep fixings free from debris or paint buildup that can impede operation.
3. Update Software and Access Credentials
For smart locks and networked systems, ensure firmware updates are applied and access codes or credentials are reviewed periodically.
4. Inspect Fixings and Mounting Points
Look for signs of tampering, wear, or corrosion. Replace any damaged or stripped security screws immediately.
5. Record and Review Access Logs
If your system offers audit trails, use them. Regularly reviewing access records can help identify unusual patterns or potential breaches.
