Best Digital Door Locks in Singapore (2026): HDB Gate & Door Bundles Ranked
Upgrading to keyless digital locks is one of the very first renovations completed by Singapore homeowners collecting keys to a new BTO flat or resale HDB. With Singapore's unique dual-barrier entrance (an outer mild steel gate paired with an inner wooden main door), selecting the right setup requires navigating SCDF fire-rated certification, synchronized dual-unlocking wireless communication, and gate-to-door handle clearance tolerances. Here is our independent 2026 guide and ranking of Singapore's 5 best digital lock brands.
Find It Fast: 2026 Digital Lock Price Benchmarks
In Singapore, purchasing digital locks as a Gate + Main Door Bundle saves between SGD 250 and SGD 500 compared to buying separate units. Pricing includes standard installation, mortise carving, wireless synchronization setup, and local on-site warranty.
SCDF Fire Door & HDB Renovation Regulations
Before purchasing any smart lock for your main wooden entrance door, you must establish whether your unit has a fire-rated main door.
π¨ How to Know If Your HDB Flat Requires a Fire-Rated Lock:
- The 3-Metre Rule: If your flat entrance is located within 3 metres of an escape staircase, lift lobby, or along an enclosed common corridor, SCDF mandates a 30-minute or 60-minute fire-rated door assembly.
- Inspect the Door Edge: Open your wooden main door and inspect the hinge-side edge for an embossed metal SCDF Certificate of Conformity (CoC) fire rating label.
- Lock Certification Requirement: If your door is fire-rated, any digital mortise lock installed must possess an SCDF-recognized fire test certificate (SS 332 or EN 1634-1). Installing an uncertified lock creates unsealed drill cavities that compromise fire containment, violating the Fire Safety Act and risking inspection failure when selling the flat via HDB resale.
Emergency Egress Rule for Gates: For safety during a corridor or kitchen fire, SCDF regulations require that the internal back-body of any digital metal gate lock must have an immediate manual mechanical release (such as a physical thumb-turn knob or emergency lever). It must never require electronic power, a code, or a key to escape from the inside.
Synchronized Dual-Unlock Tech & Handle Clearance
The most frustrating mistake made by first-time smart lock buyers is purchasing incompatible gate and door locks that require unlocking two separate apps or tapping two different fingers.
1. How Dual-Sync Works
Synchronized lock packages link the gate lock and main door lock using an encrypted Radio Frequency (RF) transmitter chip or direct Bluetooth mesh. When you scan your thumbprint or face on the outer gate lock, the gate lock triggers its internal solenoid, sends an instantaneous encrypted signal to the inner door lock, and unlatches the wooden door. By the time you push open the metal gate, the wooden door is already unlocked.
2. The Handle Clearance Gap (Avoid Clashing)
Standard HDB flat entrances feature a distance of 70mm to 95mm between the surface of the metal gate and the face of the wooden door.
- Push-Pull Handles: Flagship locks (like Kaadas K9 or Philips 9300) feature vertical ergonomic bar handles that protrude 65mm to 75mm from the door face.
- The Risk: If both the gate lock and door lock use bulky front bodies, their handles will collide and block the gate from closing shut.
- The Solution: Reputable Singapore installers pair push-pull main door locks with specialized slim-profile gate locks (e.g., Kaadas R8GD or Solity GD-65B, measuring just 13mm thick) or offset the lock mounting heights.

Frequently Asked Questions
Can I install any digital lock on my HDB main door in Singapore?
No. Under Singapore Civil Defence Force (SCDF) fire safety regulations and HDB renovation guidelines, if your HDB main entrance door is classified as a fire-rated door (mandatory for units situated along common corridors within 3 metres of a staircase or lift lobby), any replacement lock must be certified fire-rated under SS 332 / EN 1634-1 standards. Installing an uncertified digital lock breaches fire safety regulations, compromises the door's 30-minute or 60-minute fire integrity, and can void home fire insurance claims or result in a failed inspection during HDB flat resale.
What is synchronized 'One-Touch' dual unlocking for HDB gate and door?
In standard HDB layouts with an outer mild steel gate and an inner wooden main door, entering your home traditionally requires unlocking two separate locks. Synchronized dual-unlock technology connects both locks wirelessly (via encrypted RF or Bluetooth). When you verify your biometric fingerprint, 3D facial recognition, or PIN on the outer gate lock, it instantly commands the inner wooden door lock to unlatch simultaneously. You only authenticate once on the exterior gate, push open both barriers, and walk straight into your living room.
What is the minimum gap required between an HDB gate and wooden door?
The clearance distance between your metal gate and wooden door must typically be at least 70mm to 85mm for standard push-pull digital mortise locks. If the gap is narrower (common in older resale flats built in the 1980s and 1990s), the large protruding handles of the gate lock and main door lock may collide when closing. Digital lock installers solve this by installing an ultra-slim gate lock (such as Kaadas R8GD or Solity GD-65B with front body thickness under 1.5cm) or staggering handle alignments.
What happens if the digital lock runs out of battery while I am outside?
All modern digital locks provide low-battery warning chimes and LED notifications weeks before the AA/AAA batteries or rechargeable lithium packs deplete. If a lock dies completely while you are locked outside, every certified lock features emergency jumpstart terminals on its exterior underside. You can power the lock instantly by connecting a standard 9V alkaline rectangular battery against the emergency contact points or plugging in a portable USB-C power bank. Every reputable lock also includes 2 physical mechanical emergency override keys that you should store in your car or office.
Are digital locks safe against electromagnetic pulse (EMP) hacking in Singapore?
Yes. While early-generation smart locks from decades ago were theoretically vulnerable to cheap Tesla coil electromagnetic pulse devices, all modern certified digital locks from reputable brands (Aqara, Kaadas, Philips, Solity, Igloohome) feature high-voltage surge protection circuits and zinc alloy Faraday shielding that immediately ground and absorb static electricity, automatically locking down without unlatching.
