Replacing an old Samsung digital lock

Many condo and HDB units still have the Samsung lock fitted years ago. When it starts failing, you can replace it like-for-like or upgrade to Interlock Mercury. Either way, our own installers fit it, usually within the same week.

Signs it's time to replace

  • Won't auto-lock when the door closes
  • Card or tag not reading
  • Keypad or fingerprint not responding
  • Won't unlock, or jams often
  • Loose handle or a display that stays dark
  • Battery leak or rust in the battery case

Some faults can be repaired. See repair or replace for how we decide.

Like-for-like replacement

Want the same feel? Samsung digital locks continue under the Zigbang name. The Zigbang DH540 and DR900 are the usual like-for-like picks.

Older Samsung models are all discontinued, so spare parts are getting harder to find.

Upgrade option

Upgrade to Interlock Mercury

Every Mercury lock can replace a Samsung mortise lock. We drill new holes for the Mercury, but its larger body covers the old cut-out completely, so there's no patching.

  • Bigger mortise with more locking bolts
  • An extra double-lock bolt
  • Stainless steel mortise: more rust resistant and harder to break

Popular picks: Mercury X6 (face recognition), X2 and X5. Rim (add-on) locks are case by case, so send us a photo first.

FAQ for Samsung & Zigbang Digital Locks

1. Are Samsung Digital Locks discontinued?

Samsung's digital lock division has been acquired by Zigbang. In Singapore, Interlock currently stocks three authentic models: the Zigbang DR900 (fully automatic mortise lock with fingerprint, card, PIN, and emergency key backup, from $888), the Zigbang DH540 (lever handle mortise lock with card and PIN, from $579), and the Zigbang SHS 1321 (add-on rim lock with card and PIN, from $338). 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.

7. Do you provide installation services?

Yes. Interlock provides free professional installation with every lock purchase, covering wooden doors across Singapore HDB, BTO, condo, and landed homes. Includes workmanship warranty and basic usage training.

8. What happens if I forget my PIN or my fingerprint isn't recognized?

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.
