ZKTeco GL300 Fingerprint Glass Door Lock

ZKTeco GL300 Fingerprint Glass Door Lock — Hybrid Verification

The ZKTeco GL300 is a hybrid verification glass door lock that replaces mechanical keys with three independent authentication methods: fingerprint recognition, MF card (Mifare), and PIN password. It is purpose-built for frameless and framed glass doors with a thickness of 10–12 mm, making it the standard access control solution for glazed office interiors — meeting rooms, boardrooms, server rooms, manager offices, and commercial partitioned spaces across Nairobi’s corporate, hospitality, and retail sectors.

Unlike panel-dependent access control readers that require a separate electric lock, controller, and power supply, the GL300 is a fully self-contained unit. The fingerprint sensor, keypad, lock mechanism, electronics, and battery housing are all integrated into a single slim body measuring 131 × 200 × 75 mm. Installation requires no hole drilling into the glass. Consequently, the GL300 can be fitted and removed without permanently modifying the door — a significant advantage in leased commercial spaces.

Hybrid Authentication: Three Credential Methods

The GL300 supports three distinct credential types, each stored and verified independently by the device:

• Fingerprint — the ZKTeco optical fingerprint sensor captures and matches the enrolled ridge pattern. Capacity is 100 fingerprint sets. Verification is contactless-style and fast, making it suitable for frequently used doorways where queue formation at the lock is unacceptable.
• MF Card (Mifare 13.56 MHz) — the GL300 reads Mifare proximity cards at 13.56 MHz. Up to 100 card credentials can be enrolled. Cards are the preferred method where gloves, hand contamination, or temporary staff access make fingerprint enrolment impractical.
• Password (PIN) — the touch keypad accepts a numeric PIN for users who do not have an enrolled fingerprint or card. Up to 100 password sets are stored. Password entry is also the backup method if a card is lost or a fingerprint cannot be read.
• Remote control — the GL300 additionally accepts a wireless remote control for line-of-sight unlocking, useful at reception counters and security desks where staff manage door access without being physically at the door.

All four methods can be used interchangeably. Furthermore, multiple methods can be combined for higher-security multi-factor verification scenarios.

No-Drill Glass Installation

The GL300’s most operationally distinctive feature is its drill-free installation method. The lock body and backplate are clamped directly to the glass panel surface using the hardware provided. No core drilling, hole cutting, or glass modification is required. This has three practical consequences:

• Speed — a trained installer can mount the GL300 in significantly less time than a conventional glass door lock requiring core drilling
• Reversibility — the lock can be removed and the glass door restored to its original state, which is important in rented offices and serviced workspaces
• Glass integrity — eliminating drilling preserves the structural integrity of the glass panel and avoids creating stress points around a drilled hole

The compatible door thickness range is 10 mm to 12 mm, covering the majority of commercial frameless glass door installations in Kenya. The lock is designed specifically for swing-type glass doors.

Touch Keypad and User Interface

The GL300’s keypad uses a touch-sensitive numeric layout rather than mechanical buttons. Touch keypads have no moving parts to wear out under repeated use — an important consideration for high-traffic doors in commercial environments. The keypad surface is also easier to clean and maintain than recessed mechanical buttons that accumulate contamination over time.

The backlit keypad remains visible in low ambient light conditions, ensuring that staff working in dimly lit corridors or glass-partitioned spaces can enter credentials reliably at any time of day.

Power Supply and Battery Management

The GL300 runs on 4 × AA alkaline batteries with a rated battery life of above one year under typical use conditions. Battery-powered operation eliminates the need to run a power cable to the door — a practical advantage where conduit routing across a glass partition is impractical or visually unacceptable.

Two features protect against unexpected power loss:

• Low battery warning — the GL300 issues an audible and visual alert when battery charge drops to a level requiring replacement, giving users advance notice before the lock becomes inoperative
• Micro USB power port — an emergency power input allows the lock to be temporarily powered via a standard Micro USB cable if batteries are fully depleted, enabling entry to retrieve replacement batteries without a lockout situation

Door Bell Ring Function

The GL300 incorporates a doorbell ring function, allowing visitors to alert occupants before presenting credentials or waiting for remote unlock. This is particularly useful in glazed meeting rooms and private offices where occupants may not be visible from outside, or in boutique hotel rooms and serviced apartment settings where guests press the bell before a host grants access.

Operating Environment

The GL300 is rated for an operating temperature range of -25°C to 55°C. This range comfortably covers Nairobi’s ambient temperature profile across all seasons, including the hot season in northern and coastal Kenya. It also suits cooler highland environments without requiring special consideration.

The lock housing is ABS (black), providing a clean, professional appearance that pairs well with glass and aluminium architectural interiors typical of Nairobi’s modern commercial office stock.

Who Is This Product Best Suited For?

• Corporate offices with glass partition doors — Open-plan offices in Nairobi’s CBD, Westlands, and Upper Hill frequently use glass partitions for meeting rooms, server rooms, and executive offices. The GL300’s no-drill installation, 100-user capacity, and multi-credential support suit these environments directly. The fingerprint method eliminates the need to issue and track physical keys across a rotating workforce.
• Hotels and serviced apartments — Boutique hotels and serviced apartment properties in Nairobi use glass doors at bathroom entrances, gym facilities, and lounge access points. The GL300’s remote control feature, doorbell function, and MF card compatibility — paired with over one year of battery life — reduce operational overhead compared to card-only or mechanical key systems.
• Retail stores and showrooms — Glass-fronted retail spaces and brand showrooms require a lock that is both functional and visually unobtrusive. The GL300’s slim black ABS profile and touch keypad maintain the aesthetic intent of the shopfront design while providing multi-factor access control.
• Schools, universities, and training facilities — Computer labs, libraries, and staff-only areas commonly use glass doors. The GL300 supports up to 100 enrolled fingerprints — sufficient for most individual room deployments — and the no-drill installation allows locks to be repositioned as room usage changes.
• Co-working spaces and serviced offices — Facilities with rotating tenant populations benefit from the GL300’s ability to enrol and delete individual credentials without rekeying. A departing tenant’s fingerprint, card, or PIN can be removed from the device in seconds, with no locksmith visit or hardware replacement required.
