Why it matters
Built for how you actually get home.
A Dependable Digital Lock, Now Under Zigbang
The Samsung DH540 was originally part of Samsung's digital lock line; following Zigbang's 2022 acquisition of that business, it's now sold under the Zigbang name as the same product, with the same manufacturing standards behind it.
Ways to Unlock
PIN and card access, with a choice between automatic and manual locking mode selection, plus a manual lock lever on the inside for quickly securing the door by hand when you're staying in for the night.
Security & Everyday Modes
A break-in alarm and low battery notification are built in, alongside silent mode for quiet nights and away mode for longer trips.
Power
An emergency 9V external terminal provides backup power if the internal batteries run flat, so you're never stuck outside waiting on a battery replacement. Made in Korea.
