When considering aftermarket upgrades for vehicle security and convenience, the Akozon LB-405/L237 Universal Keyless Entry System emerges as a compelling solution for drivers seeking to modernise their car’s central locking capabilities. Designed as a universal fitment, this central locking kit integrates a keyless entry mechanism, remote boot release, and door lock automation into a single package. Its appeal lies in its adaptability to a wide range of vehicle models, provided they operate on a 12V electrical system, making it a versatile choice for those looking to retrofit older vehicles or enhance base-model specifications.
Core Specifications and Engineering
At its heart, the LB-405/L217 employs a robust RF (Radio Frequency) remote system with a stated operating range of up to 50 metres under optimal conditions. The dual-channel remote fob controls both door locks and boot release, while the system’s rolling code encryption technology addresses security concerns inherent in older fixed-code systems. The kit includes a central control module, four actuator motors (suitable for front and rear doors), reinforced wiring harnesses with inline fuses, and a detailed installation manual. Compatibility extends to vehicles with either positive or negative door lock trigger systems, a critical detail praised by installers working on Japanese and European marques alike. The inclusion of a dedicated boot release relay demonstrates thoughtful engineering for estate cars or saloons with separate tailgate mechanisms.
Installation and Practical Application
Feedback from users highlights the system’s straightforward installation process when compared to rival universal kits. One mechanic noted: “The colour-coded wiring diagram eliminated guesswork – it’s rare to find aftermarket kits with such clear documentation.” The control module’s compact dimensions (85x60x25mm) facilitate discreet placement behind dashboard panels or within door cavities. However, some users recommend allocating 3-4 hours for first-time installations, particularly when retrofitting vehicles without existing central locking infrastructure. The actuators’ 5kg pulling force proves adequate for most door mechanisms, though heavy-duty springs on certain 4×4 models may require additional reinforcement.
Security Considerations
In an era where relay attacks threaten keyless entry systems, Akozon’s implementation of dynamic encryption provides a notable security upgrade over basic aftermarket solutions. The system’s anti-scanning protocol, which alters transmission codes with each use, has drawn positive remarks from security-conscious users: “Finally feel confident leaving the car in public car parks – the rolling code actually works as advertised.” While not equivalent to manufacturer-fitted systems with motion-sensor fobs, this represents a significant improvement over traditional central locking remotes vulnerable to code-grabbing devices.
User Experience and Performance
Practical testing reveals consistent performance across temperature extremes, with the system maintaining functionality between -20°C and 70°C – a crucial factor for UK motorists facing seasonal weather variations. The tactile rubber-coated remotes receive particular praise for their ergonomic design, with one user noting: “Buttons have proper feedback, not that cheap mushy feel you get with budget kits.” Battery life on the two-button fobs averages 18-24 months with regular use, while the central module draws less than 0.5mA in standby mode, preventing parasitic battery drain.
Integration with Vehicle Systems
The LB-405/L237’s ability to interface with existing alarms or immobilisers through its programmable output ports enhances its appeal as part of a comprehensive security upgrade. Several users successfully integrated the system with aftermarket CANbus interfaces, enabling features like automatic window closure upon locking. The boot release function operates independently through a 30A relay, capable of handling tailgate solenoids or electronic latches without requiring additional components.
Long-Term Reliability
Field reports suggest impressive durability, with early adopters confirming trouble-free operation beyond the two-year warranty period. The IP54-rated actuators withstand typical door panel moisture ingress, though installers advise applying dielectric grease to connectors in coastal regions. One long-term user commented: “Three winters on, no failed actuators – the nylon gears haven’t stripped like cheaper units I’ve tried.” The system’s fail-safe design defaults to manual operation should electrical power be interrupted, ensuring vehicle accessibility in emergencies.
Comparative Advantages
Where the Akozon kit distinguishes itself from competitors is in its balanced approach to functionality and user customisation. The adjustable locking/unlocking speed (configurable via DIP switches) allows fine-tuning to match specific door mechanism responses – a feature typically reserved for premium systems. Moreover, the inclusion of both ‘single-point’ and ‘all-door’ activation modes provides flexibility for commercial vehicles or families needing selective access control.
Conclusion
For motorists prioritising a cost-effective route to modern vehicle security without compromising on reliability, the Akozon LB-405/L237 presents a well-engineered solution. Its combination of dynamic encryption, weather-resistant components, and user-friendly installation positions it as a pragmatic choice in the universal central locking market. While professional fitting is advisable for complex vehicle electronics, competent DIY enthusiasts will appreciate the logical design and comprehensive support materials. As one satisfied user summarised: “Transformed my 15-year-old workhorse into something that feels properly modern – can’t believe I waited this long to upgrade.” For those seeking to bridge the gap between basic manual locks and contemporary keyless entry expectations, this system delivers measurable improvements in both convenience and theft deterrence.
