Solity (Korean: 솔리티) is a South Korean technology company focused on smart door locks, access control systems, connected security services, and Original Equipment Manufacturer (OEM)/Original Design Manufacturer (ODM) production. The company traces its corporate lineage to 1980, beginning as a metal-foundry business before developing expertise in mechanical keys and eventually transitioning into the digital security market 12.

Currently, Solity positions itself as a global provider of smart-opening solutions, integrating hardware with biometric authentication, Internet of Things (IoT) connectivity, cloud-based management, and software services. Its products are marketed under the main Solity brand, alongside subsidiary lines including TANK, SYNC, and WELKOM.

The company’s official corporate materials describe it as a “smart opening solution” provider, while its international presence emphasizes its role as a global manufacturer and OEM/ODM partner 2.

1980–1996: Foundations in Metalworking

The company’s origins date back to April 1980, when its predecessor, Daeheung General Metal, was established as a metal-foundry firm. This early period built the manufacturing and metallurgical capabilities that would later support its expansion into security hardware.

In 1997, the entity established Hye Gang Precision and shifted its operational focus toward the production of mechanical keys. This transition provided the foundational experience in lock mechanisms and physical security hardware.

2004: Entry into Digital Security

A pivotal moment occurred in 2004 with the launch of the BON series, the company’s first line of digital door locks. This marked the strategic shift from traditional mechanical key manufacturing to the emerging electronic and digital-security market.

2007–2014: Expansion and R&D

During the late 2000s and early 2010s, the company expanded its portfolio and secured various quality certifications:

• 2007: Obtained initial KS certifications and ISO 9001 quality-management certification.
• 2008: Established Hye Gang Security Inc.
• 2011: Introduced the VOLT mortise lock.
• 2012: Developed push/pull door-lock technology and initiated additional ODM partnerships.
• 2014: Opened a dedicated Research & Development center and expanded domestic factory capacity.

The company states that its R&D division focuses on creating smart locks tailored for diverse global markets, with a quality laboratory conducting over 56 types of reliability tests.

2015–2018: Growth and Brand Diversification

By 2015, cumulative production surpassed 3 million units. During this phase, the company introduced distinct consumer brands to target different market segments:

• TANK: Positioned as a premium smart/digital door-lock line.
• SYNC: Focused on practical, value-oriented smart locks.
• WELKOM: Designed primarily for online retail channels.

In 2018, the company opened a manufacturing facility in Vietnam, reinforcing its international production strategy.

2019: Rebranding to Solity

In May 2019, the corporate name was officially changed to Solity. The brand name is derived from the concepts of “Solid” and “Security.” This rebranding signaled an ambition to evolve beyond being solely a digital lock manufacturer to becoming a comprehensive provider of integrated smart-opening and access solutions 2.

Smart and Digital Door Locks

Solity offers a wide range of locking mechanisms suitable for various door types and security needs:

• Push-pull smart locks
• Mortise locks
• Rim/auxiliary locks
• Handle-integrated digital locks
• Keyless retrofit/no-drill locks
• Glass-door locks
• Sliding/sash-door smart locks
• B2B-specific door locks

The product catalogue also includes digital safes and smart home cameras.

Authentication Technologies

A core aspect of Solity’s development involves replacing conventional physical keys with electronic and biometric alternatives. Depending on the model, their locks support:

• PIN/password entry
• Smart cards
• Physical/mechanical keys
• Smartphone integration
• Fingerprint recognition
• Facial recognition
• Palm-vein recognition

Newer models feature advanced biometrics such as 3D facial recognition and 3D palm-vein recognition. For instance, the P7000-V utilizes 3D palm-vein recognition, while the WSP-2900A employs 3D deep-learning facial recognition.

Smart Home and IoT Integration

Solity has increasingly integrated its hardware with connected ecosystems. Its service portfolio includes platforms like SmartSOLITY and SOLITY Connect, with compatibility noted for external IoT standards including Matter, Amazon Alexa, and Samsung SmartThings.

Key features of their smart-access concept include:

• Remote door-lock control
• Real-time access monitoring
• Centralized access management
• Smartphone-based unlocking
• Cloud-connected services
• Integration with third-party smart-home platforms

This approach represents a shift from standalone hardware manufacturing to broader connected access management 3.

Significant portions of Solity’s business involve OEM/ODM manufacturing. The company provides end-to-end services covering:

1. Product planning
2. Product development
3. Manufacturing
4. Shipment
5. Consulting

Solity operates as a global partner for major companies, meaning its technology and manufacturing processes may appear in products sold under other brands in addition to those carrying the Solity name.

Solity

The flagship brand focuses on smart access and premium/value-oriented digital door locks, featuring fingerprint, facial-recognition, and palm-vein-recognition models.

TANK

Positioned as a premium smart-door-lock brand, emphasizing differentiated technology and refined design aesthetics.

SYNC

Targeted at consumers seeking practical and rational smart-door-lock solutions.

WELKOM

Described as an online-focused brand, offering push-pull, retrofit/no-drill, and other smart-lock products.

Since launching its first digital lock in 2004, Solity’s technology strategy has evolved to encompass several key areas:

• Electronic access control
• Biometric authentication (fingerprint, 3D face, palm vein)
• Smartphone access protocols
• IoT connectivity
• Cloud-based access management
• Smart-home ecosystem integration
• Push-pull locking mechanisms
• Connected security services

The company reports holding more than 120 patents and utility models and maintains rigorous pre-launch reliability testing protocols.

Within South Korea, Solity maintains a substantial installation and after-sales network. Corporate materials indicate the operation of more than 1,000 installation stores nationwide and a specialized customer center operating 24 hours a day, 365 days a year. Internationally, the company supports its supply chain through its Vietnam factory established in 2018.

Solity identifies itself as a leading smart-door-lock company in South Korea, citing significant domestic market share and extensive service infrastructure. Independent analyses note that market-share figures can vary by methodology; therefore, company-reported statistics should be viewed within that context.

Recent corporate listings describe Solity as a smart-security-solutions firm focusing on smart door locks, cloud-based access-control services, and global ecosystem integration.

Current Direction

The most notable strategic shift in recent years is the movement from pure hardware sales to integrated access solutions. Rather than viewing smart locks merely as electronic replacements for keys, Solity is developing an ecosystem where locks communicate with apps, cloud platforms, and smart-home systems. This aligns with the broader global trend toward connected access control, where physical security hardware, software, and cloud services operate as a unified system 3.

The legal entity is listed as 주식회사 솔리티 (Solity Co., Ltd.), headquartered in Yangcheon-gu, Seoul. The company’s evolution can be summarized as:

Mechanical keys → digital door locks → biometric locks → IoT-connected locks → cloud-based access solutions

Solity continues to expand its international footprint through both B2C sales of branded products and B2B OEM/ODM partnerships.
