Which unlocking technology survives humid Singapore corridors, elderly parents with worn fingerprints, and kids?

|---|---|---|---|
| Infrared Palm Vein Recognition Solity, Philips, Aqara, Kaadas |
Scans sub-dermal blood vessel patterns when you wave your palm 10–25cm in front of the lock. | Elderly parents & helpers whose dry or worn thumbprints fail standard capacitive sensors; works even with wet hands. | 5,000mAh rechargeable Li-ion (4–6 months per USB-C charge) |

| 1-Touch Dual-Sync (Gate → Door) Solity, Philips, Igloohome, Kaiser+ |
Scanning your finger/face on the outer metal gate lock sends an encrypted RF signal to unlatch the wooden main door simultaneously. | All HDB flats with both a metal gate and wooden door. Cuts entry time in half. | Gate lock: 4–8× AA Alkaline (10 mos); Door lock: AA or Li-ion |
| Apple HomeKey & Offline AlgoPIN Aqara D200i / U200, Igloohome |

HDB Digital Lock Rules, SCDF Fire Certification & Buyer FAQ
Essential checks before replacing your lock or ordering a BTO/Resale Door + Gate bundle.
1. How much gap do I need between my HDB door and metal gate?
Measure from the exterior face of your wooden main door to the nearest inner bar or mesh of your metal gate. Standard push-pull locks require 65mm to 75mm. If your HDB clearance is 42mm to 58mm, choose a slim-chassis lock (such as the Schlage S-6800, Aqara D200i, or Philips 9300 Slim) or upgrade to a curved/recessed lock-box gate via our PwP partners.
2. How do I verify if a digital lock is genuinely SCDF fire-rated in Singapore?
Every SCDF-approved fire-rated digital lock in Singapore is tested to SS 332:2018 (30 or 60 minutes) and carries a physical TÜV SÜD PSB or SETSCO fire-rating serial label on the mortise edge alongside a Certificate of Conformity (CoC) matching your HDB door thickness.
3. Why should I only use Energizer MAX Alkaline batteries in AA-powered digital locks?
High-capacity rechargeable AA batteries or heavy-duty carbon-zinc batteries can leak potassium hydroxide in Singapore's tropical humidity or drop voltage abruptly without triggering the low-battery chime. Manufacturers require standard 1.5V Alkaline batteries (or the factory rechargeable Lithium pack for 3D Face/Video locks) to keep your motherboard warranty valid.
4. What happens if the digital lock battery dies completely while I am outside?
Every HDB digital lock listed on digitallocks.sg includes two emergency overrides outside the flat: (1) an emergency USB Type-C 5V power bank port on the bottom edge of the exterior handle to jump-start the lock in 3 seconds, and (2) 2 mechanical override keys that you can keep in your car or parents' home.
5. Do I need an SCDF fire-rated digital lock for my HDB flat in Singapore?
Under SCDF Fire Code and HDB rules, if your flat's main entrance door is within 3 metres of the lift lobby or staircase (which applies to most BTO and newer resale HDB flats), both the timber door and the digital mortise lock must hold a valid TÜV SÜD PSB / SCDF SS 332:2018 30-minute or 60-minute fire-resistance certificate.
6. What is a Dual-Sync HDB door and gate digital lock?
A Dual-Sync bundle links the outdoor metal gate lock and the indoor wooden door lock via encrypted short-range wireless pairing. When you scan your fingerprint, palm vein, or 3D face on the outer metal gate lock, both the metal gate and the wooden main door unlock simultaneously in 0.8 seconds—so you only authenticate once.
7. How do I get a free digital lock with a main door and metal gate bundle?
Instead of buying locks separately at retail price ($900–$1,400), claim one of the Partner Vouchers on digitallocks.sg. When you book an HDB Fire-Rated Main Door + Mild Steel Laser-Cut Gate bundle (typically $1,688 to $2,288) or BTO renovation package, participating Singapore door factories include a Dual-Sync Door & Gate Digital Lock set free.
