All three carry the same trusted Korean security technology and include auto-locking.

2. What's the difference between Samsung Digital Locks and Zigbang Digital Locks?

The technology, build quality, and user experience are identical. The brand name changed when Samsung sold its lock division to Zigbang. Models like the DR900, DH540, and SHS 1321 continue under the Zigbang name with the same Korean security engineering Singapore homeowners know from Samsung.

3. Can I install a Samsung or Zigbang Digital Lock on my HDB or Condo door?

Yes. These locks are designed for Singapore homes, including HDB, BTO, condos, and landed properties. The DR900 and DH540 are mortise locks requiring two holes in the door. The SHS 1321 is a rim lock requiring only one hole and keeps your existing handle in place. Our installation team can help confirm compatibility before purchase.

4. How do I unlock the digital lock if the battery runs out?

Most Samsung Zigbang locks have an emergency power terminal. Connect a 9V battery or power bank to temporarily power the lock and enter your PIN or card to unlock. The DR900 also carries an emergency mechanical key as an additional backup.

5. Can I control my Samsung/Zigbang Digital Lock remotely?

These three models do not support app connection. All these locks are connected only locally.

6. Are these locks secure against hacking or unauthorized access?

Samsung Zigbang locks use advanced encryption and security protocols to prevent hacking, along with anti-tamper alarms, auto-locking, and biometric authentication for additional layers of security.

You can reset your PIN using the master settings. If fingerprint access fails, use your backup PIN or RFID card. The DR900 also carries an emergency mechanical key as a final fallback.

9. How long do the batteries last?

Typically 6 to 12 months on standard AA batteries depending on usage frequency. A low-battery warning alerts you in advance so you can replace them before the lock runs flat.
