KFC-style Aluminum Storefront Smart Lock SK-K8 Pro — Fingerprint Password Keyless Lock for Narrow Shop Front Doors

SK-K8 Pro: A No-Drill Smart Lock for KFC-style Storefront Doors

The SK-K8 Pro is a slim, surface-mounted smart lock purpose-built for narrow-frame broken-bridge aluminum KFC-style shop front doors. It replaces the old mechanical KFC lock body without drilling new holes — a direct swap that turns any retail storefront into a keyless access point.

Key Features

• 4 unlock methods standard: fingerprint, PIN code, 13.56 MHz IC card, and mechanical emergency key.
• Optional TTlock mini-program / app for remote passcodes and cloud audit trail.
• No-drill installation: matches the standard KFC lock body footprint — swap out the old lock, bolt in the SK-K8 Pro.
• Aluminum alloy housing with a slim 40 mm-wide faceplate designed for narrow aluminum profile doors.
• 50 fingerprints, 20 PIN groups, 50 IC cards — enough for most single-store teams.
• Door thickness 38–58 mm support.
• 4 x AA battery operation (low-battery alert).
• Always-open mode and silent setting for retail operating hours.

Typical Applications

• KFC / McDonald’s / fast-food chain storefronts
• Cafe and coffee shop narrow aluminum glass doors
