About Interlock Singapore
Digital Lock Specialists Since 2008
Interlock Singapore is a digital lock specialist company focused exclusively on smart and digital locking solutions. Since 2008, we have dedicated our work to one domain only: understanding, installing, repairing, replacing, and developing digital locks for real Singapore homes.
We do not sell doors.
We do not sell gates.
We specialise entirely in digital locks.
This focus defines who we are and how we deliver better outcomes for our customers.
Our Origins: Early Adoption and Industry Leadership
Interlock began in 2008 as one of Singapore’s early digital lock retailers and installers, at a time when digital locks were still uncommon and poorly understood. In the late 2000s and early 2010s, the market was dominated by Korean-manufactured digital locks, which were widely regarded as the benchmark for reliability and build quality.
During this period, Interlock worked extensively with established Korean brands such as Samsung and Gateman, and quickly became well-known for proper installations, strong product knowledge, and dependable after-sales support. As digital locks gained popularity, Interlock was recognised as a trusted name in the category.
Market Evolution and Strategic Adaptation
By the mid-2010s, the digital lock landscape began to change. User expectations evolved rapidly, driven by the rise of smartphones, smart homes, and connected devices. Features such as mobile app access, advanced biometrics, and ecosystem integration became increasingly important.
At the same time:
- Samsung exited the digital lock market
- Feature development among traditional Korean brands slowed
- New international brands entered the Singapore market with faster innovation cycles
- Rather than remaining tied to legacy products, Interlock adapted to these changes.
Leadership and Resurgence
To lead the company into its next phase, Alex, Interlock’s current Director, spearheaded a strategic renewal from the mid to late 2010s onward.
Under his leadership, Interlock:
- Expanded beyond legacy Korean brands
- Introduced trusted international digital lock brands such as Lockin, Aqara, and Solity
- Modernised its product portfolio to meet evolving smart home and security expectations
This period marked Interlock’s return to industry leadership, driven by adaptability, product discernment, and technical competence rather than brand loyalty alone.
Industry Trust & Media Engagement
As the digital lock market continues to evolve, Interlock is increasingly consulted as a subject-matter expert beyond direct customer work. In 2025, Interlock was approached by mainstream media organisations such as CNA to provide professional commentary and technical perspectives on digital lock–related issues.
These engagements reflect long-term, hands-on experience across installations, repairs, product failures, and real-world usage — positioning Interlock as a trusted industry reference rather than a marketing voice.
Independent Technical Reviews & Community Recognition
Interlock’s work has also been recognised within the local smart home and technology community. Our digital lock solutions were featured by well-known Singapore smart home reviewer Alex Teo, who ranked Interlock as the No.1 digital lock in his “50 Smart Digital Locks” showcase and named it his personal favourite.
This recognition came from independent, hands-on evaluation rather than sponsorship, reinforcing Interlock’s standing among experienced users and technical reviewers.
From Integration to Creation: Why Interlock Mercury Exists
Years of working across multiple brands provided Interlock with uncommon insight. By installing, repairing, replacing, and troubleshooting a wide range of digital locks — including models we do not sell — we developed a deep understanding of how different designs perform in real Singapore conditions.
We observed recurring challenges:
- Global products designed without local context
- Limited flexibility for door-and-gate combinations
- Poor adaptation to Singapore’s climate and housing constraints
- A gap between advanced features and practical reliability
- These insights led to a clear conclusion: true localisation required ownership of the product itself.
The Interlock Mercury Series
Interlock Mercury was developed as a locally-optimised digital lock series shaped by real installation experience and long-term technical knowledge.
The Mercury series is designed specifically for Singapore homes, with considerations such as:
- Dual door-and-gate lock synchronisation
- Weather-resistant gate lock construction
- Advanced biometric options, including facial recognition and palm vein access
- Refined aesthetics suited for modern residences
- Dedicated models for:
- Main doors
- Metal gates
- Glass doors
- Sliding doors
We also customise solutions to adapt certain door lock designs for gate use where appropriate, a capability made possible only through deep specialisation and technical confidence.
Why We Only Specialise in Digital Locks
Interlock’s decision to focus exclusively on digital locks is deliberate.
By specialising in a single category, we are able to:
- Develop deeper technical understanding of lock mechanisms and components
- Identify common failure points across brands
- Improve repair accuracy and installation reliability
- Make better product recommendations based on real usage patterns
- Design better products through informed iteration
We believe focus leads to mastery and mastery leads to better outcomes for users.
A Complete Digital Lock Solution
Interlock is neither just a retailer nor only a manufacturer. We provide a complete digital lock solution that spans the entire lifecycle of ownership:
- Pre-sales consultation and compatibility assessment
- Professional installation
- Digital lock repair and troubleshooting
- Lock replacement and upgrades
- After-sales support
- Cross-brand expertise, including locks not sold by Interlock
This integrated approach ensures that recommendations are practical, not sales-driven.
User-First, Always
Even with our own Mercury series, Interlock continues to offer and recommend other brands when they better suit a customer’s needs. Different homes, doors, and users require different solutions.
Our principles remain consistent:
- Correct fit matters more than brand
- Reliability matters more than novelty
- Long-term usability matters more than short-term sales
This user-first philosophy has guided Interlock since 2008.
Looking Ahead
From early adoption to market adaptation, and from brand integration to local product development, Interlock continues to evolve with a single purpose:
To deliver the most reliable, technically sound, and locally-optimised digital lock solutions in Singapore.
Interlock exists not simply to sell locks, but to solve access, security, and convenience properly — through expertise, focus, and experience.
