MC-S603LH3 is an aluminium-alloy smart lock built around a 6068 standard mortise and a C-grade brass cylinder. It supports fingerprint, password, card, temporary password and mechanical key access, and runs on four AA batteries at DC 6 V. The 374 × 72 × 70 mm housing fits door thicknesses from 50 to 110 mm.
The lock provides anti-tamper, low-battery and trial-error alarms, and a USB backup power port for a flat battery. It operates stand-alone, so it does not need a network or a hotel management system. For apartment operators who need remote issuing and revocation, compare the Wi-Fi model MC-S603LF1.
Typical installations include apartment entrance doors, villa side doors, office suite doors and staff rooms. Confirm the door thickness, mortise type, handle direction and fire-door requirement before ordering; the lock is not a substitute for a fire-rated door closer or exit device.
