Electronic Smart Door Lock with Passcode, Smart RFID Card & Mechanical Key – No DC

Upgrade home, office, or rental property access security with keyless convenience and dependable mechanical reliability using the 3-in-1 Electronic Smart Door Lock (Passcode Keypad, RFID Card & Traditional Key – No DC). Designed for straightforward retrofit installation on standard interior and exterior doors, this digital lock eliminates the hassle of carrying bulky key rings while keeping entry fast, flexible, and tamper-resistant.

Operating 100% battery-powered (no hardwired DC power supply, trailing electrical cables, or wall transformers required), it installs cleanly onto wooden, composite, or metal doors without electrical trenching, messy conduit, or costly electrician call-out fees.

  • Digital Touchscreen / Silicone Keypad Passcode: Backlit numeric keypad supports customizable 4–9 digit PIN codes for daily family or staff access.

  • Low-power standby circuit provides 10 to 12 months of daily operation under normal household usage.

  • Low-battery audible chime and visual LED indicators trigger weeks in advance to signal battery replacement.

  • External Emergency Power Port: Features a concealed 5V Micro-USB / Type-C port on the bottom exterior panel, allowing you to jump-start the lock instantly using a standard portable power bank if batteries are completely depleted while away.

• Heavy-Duty Construction & Tamper Resistance:

  • Solid die-cast zinc alloy or stainless steel body resistant to impacts, drilling, and weathering.

  • Free-floating clutch handle mechanism disengages when locked to prevent forced lever tampering.

  • Auto-lock security mode automatically relocks the door after 5 seconds of entry to prevent accidental walk-away breaches.
