Smart Glass Door Lock Perfiware 4in1 Biometric Fingerprint LG2315

In this review the Perfiware Smart Glass Door Lock LG2315 is evaluated for everyday use on frameless push-pull glass doors. The bottom line: it is best for offices, apartments, and hotel-style interiors where a drill-free, high-capacity biometric lock is needed. The reviewer found the standout reason to buy is the combination of fast fingerprint recognition and a fully drill-free install that preserves the glass panel while offering multiple access methods.

Key Features

• Drill-free installation: The one-piece design fits 10mm-12mm glass and installs without damaging the door, making it practical for rental offices and retrofits.
• Fast biometric unlocking: Advanced fingerprint recognition provides quick and accurate unlocking, reducing delays for frequent users.
• Four unlocking methods: Supports fingerprint, password (with virtual 16-digit privacy mode), IC card, and remote control for flexible access management.
• Large user capacity: Stores up to 100 users, 100 fingerprints, 100 cards and 10 remotes, with each user allowed up to three fingerprints for convenience.
• Auto and manual locking modes: Auto-lock on door closure, constant open option, and manual lock via long press for varied security needs.
• Robust stainless construction: Built to handle left/right and double/single opening frameless glass doors for broad compatibility.

Who It's For

The LG2315 suits building managers, small business owners, and homeowners who need a secure, neat solution for frameless glass doors without altering the glass. It is particularly useful where multiple employees or residents require quick, contactless access and administrators want centralized control via cards and remotes.

Those with sliding glass doors or thicker/unsupported glass should look elsewhere, since this model is not compatible with sliding systems and is optimized for 10mm-12mm glass with a 4mm-15mm door gap. Buyers should measure door thickness and gap before ordering to ensure fit.

Pros & Cons
