Understanding Central Locking Systems and ELS (Electronic Locking Solution) Ecosystems!

What is Electronic Locking? (Central Locking / ELS)

Modern electronic locking technologies, (including Central Locking Systems and Electronic Locking Solution [ELS] Ecosystems) are designed to provide convenient and reliable remote security control for doors, storage compartments, and enclosed equipment. They build on traditional locking principles while introducing different methods of operation and electronic system integration.

Central locking and ELS components can use different engineering architectures to maintain secure locking performance even when the system is not electrically energised. The two most common design methods that are relied upon are:

1. Mechanical Actuator Units

These are electronically activated locking mechanisms, generally driven via a series of mechanically connected linkages or gears.

Traditional central locking systems are commonly built around mechanical actuator units operating on 12V or 24V power supplies. When a lock or unlock signal is sent, the actuator moves internal components such as shafts, linkages, worm gears, or cam mechanisms to physically engage or release the locking pawl.

In most actuator-based systems, the handle remains in its locked or unlocked position until an opposite electrical signal is received.

2. Solenoid-Based Units

These rely on solenoid-based electromagnetic hold technology to disengage and control the position of the locking mechanism.

Instead of maintaining position through mechanical drive, internal solenoid-based designs utilise a briefly stored electrical charge to electromagnetically control the position of the locking pin/pawl mechanism.

When the key remotes lock or unlock button is pressed, it generates a brief electrical signal that energises the solenoid and holds the locking pin’s position in the unlocked (open) state using electromagnetic force.

When the electrical signal stops and as the stored charge dissipates, the solenoid loses its electromagnetism and releases its hold, allowing the latch to automatically return to its default locked (closed) state.

OEM, Aftermarket, and Integrated Ecosystems Explained…

Modern locking technology is not limited to a single product type or power configuration. Instead, many solutions operate as part of a broader locking ecosystem that may combine mechanical, electronic, and digital access control methods.

In general terms, locking systems can be broadly considered across four operational environments.

1: Mechanical Locking Actuation (MLA)

Mechanical Locking Actuation (MLA) refers to traditional locking mechanisms that operate without electronic signal input or powered componentry.

These systems rely on manual interaction to engage or release the locking mechanism and are commonly found in conventional latches, handles, and non-electronic locking assemblies.

MLA solutions remain widely used where simplicity, reliability, and zero electrical dependency are primary design considerations.

2: OEM Vehicle Locking Systems

Original equipment vehicle locking systems are typically powered by the vehicle’s primary electrical architecture and communicate through the vehicle’s electronic control unit (ECU).

These systems are designed to integrate directly with factory central locking functions, allowing doors, cabins, or storage compartments to be locked or unlocked using the vehicle’s standard remote or control interface.

3: Aftermarket and Self-Contained Central Locking Systems

Aftermarket central locking solutions are often designed to be-able-to operate independently from the vehicle’s OEM locking architecture.

These systems may use separate power sources such as auxiliary vehicle batteries, standalone 12V or 24V supplies, or low-voltage configurations such as 6V compression latch systems powered by 4 x AA batteries or alternate 6V power supply.

Self-contained systems are commonly used in applications such as:

Caravan and recreational storage compartments
Service body toolboxes
Independent canopy locking systems
Equipment drawers or small enclosure access points

For example, electronic locking compression latch products within Selectlok's NP0044 range can operate as semi-wireless solutions when powered by internal battery sources, allowing secure remote locking without requiring additional wiring integration.

4: Electronic Locking Solution (ELS) Ecosystems

Electronic Locking Solution (ELS) ecosystems exist where multiple locking and control components are configured to operate together.

An ecosystem configuration may include:

Integration with OEM vehicle central locking signals
Multiple locking handle styles within a single system
Mixed voltage architectures (such as 6V, 12V, and 24V components)
Control modules, power management components, and accessory charging systems

An ecosystem may also include advanced configuration elements such as:

Customised actuation behaviours
Multi-pulse triggering requirements
Door or lock position sensors
Advanced wiring or power conversion architectures

However, modifying factory-configured timing, signal behaviour, or actuation characteristics outside recommended engineering parameters is strongly discouraged, as this may impact system reliability and warranty coverage.

A locking ecosystem can therefore be understood as any configuration where multiple components, power sources, or control signals operate collectively as part of an integrated security architecture.

Practical Examples of Ecosystem Integration

Locking ecosystem designs may be used to combine different product types within the same installation, such as:

Vehicle cabin doors using OEM central locking
Canopy doors using actuator-based locking handles
Underbody storage compartments using low-voltage compression latches

These configurations allow security and accessibility requirements to be balanced across different access points within a single platform.

So What Now?

Your choice of locking technology largely will depend on the installation environment, security requirements, and system integration of the design.
