What Welock does
Welock is a Shenzhen-based manufacturer of smart electronic cylinder locks founded in 2013, specializing in retrofit lock solutions for both Euro-profile and American cylinder doors. The product portfolio spans fingerprint-enabled cylinders (ToucA51, Touch63, Touch41, Touch61, SECBR, U71, U81), keypad cylinders (PCB41, PCB41 Plus, PCB51), and American-cylinder variants (PCB32 knob, PCB33 lever, PCB34 deadbolt), plus accessories including the WIFIBOX3 Bluetooth-to-WiFi gateway, RFID cards, and a door sensor. Core technology includes capacitive fingerprint recognition (0.3-second response, 98% accuracy, ML-assisted improvement after ~20 readings), 13.56 MHz MIFARE RFID, Bluetooth LE app access, and optional WiFi remote control. Locks feature local-first biometric and passcode storage with AES-encrypted app communication, IP65 weather resistance, operating temperatures of -25°C to 60°C, ANSI/BHMA Grade 2 certification on the PCB34, and a 10-minute DIY installation with no drilling or rewiring.
WELOCK's go-to-market is product-led and direct-to-consumer, combining its own e-commerce storefront (welock.com) with Amazon.de and Amazon.com marketplace listings, supported by local warehouses in Europe and the US. Revenue is generated almost entirely through one-time hardware sales at price points between €16.99 and €299, with upsell from accessories such as the €99 WIFIBOX3 gateway; no subscription is required for core lock functionality. The customer base is highly fragmented across residential homeowners, short-term rental hosts (Airbnb, Booking.com), apartment renters, and small businesses, with marketing conducted through SEO, YouTube reviews, an affiliate program, and active social media on Instagram, Facebook, TikTok, Pinterest, YouTube, and LinkedIn. The company remains privately held with no disclosed funding rounds, valuation, executive leadership team, revenue, or patent portfolio in the public record.
