An auto door lock — a digital lock that secures itself automatically the instant the door shuts — is one of the simplest upgrades that genuinely changes daily life in a Singapore home. You stop carrying keys, you never again wonder if you locked up on the way to work, and letting family or a helper in becomes a fingerprint or a PIN instead of a spare-key handover. This guide compares the auto-locking digital locks that work well on Singapore’s HDB and condo doors and helps you pick the right fit.
We stuck to brands with genuine local installation, warranty and servicing, since fitting quality and after-sales support matter more than a spec sheet on a front door. Whether you want a simple fingerprint-and-PIN lock, a push-pull handle for a slick condo entrance, or an app-connected model with entry alerts, these picks cover typical Singapore doors, our year-round humidity and realistic SGD budgets.
What to look for in Singapore
- Make sure auto-lock genuinely triggers on door close, and that you can pause it easily when carrying items in and out or ventilating the flat.
- Match the lock body to your door — a mortise lock fits most solid main doors, a slim rim lock is required for a thin HDB metal gate.
- Choose multiple unlock methods (fingerprint, PIN, card, app) so no single failure ever locks the whole household out.
- Prioritise a good-quality fingerprint sensor, because our heat and humidity can defeat cheap readers when fingers are damp or sweaty.
- Look for anti-peep PIN entry, auto-lock and a tamper/jam alarm since main doors sit in a shared corridor or lobby.
- Check battery life and a low-battery alert, and prefer USB-C emergency power so a dead battery never strands you outside.
- Decide whether you need Wi-Fi/app remote unlocking and entry logs, or whether offline Bluetooth and PIN entry cover your needs.
- Pick a brand with authorised Singapore installers (Kaadas, Yale, Philips, igloohome, Hafele) so installation, warranty and repairs stay local.

igloohome Smart Lock
igloohome, a Singapore brand, shines for households that grant access often — its offline algoPIN lets you issue one-time or time-limited codes remotely without the lock needing Wi-Fi. Auto-lock and PIN entry are reliable and local support is close at hand. Ideal if you regularly let in cleaners, guests or family while you are out.
Pros
- Offline remote PIN codes
- Singapore brand, strong local support
- Great for helpers and short-term guests
Cons
- Fingerprint only on higher models
- Some app unlocking is Bluetooth-range only
The verdict
For most Singapore homes a Kaadas push-pull or mortise auto-lock is the best all-rounder, blending effortless entry, reliable biometrics and wide local support; pick Philips for premium looks and advanced biometrics, or igloohome if remote, offline access for guests and helpers is your priority.
Frequently asked questions
Is an auto door lock the same as a digital lock?
An auto door lock is a digital lock with the auto-lock feature switched on, meaning it re-locks itself the moment the door closes so you never leave it unlocked by accident. Almost all modern digital locks from Kaadas, Yale, Philips and igloohome include auto-lock, which you can usually toggle off temporarily when needed.
What if I get locked out when the battery is flat?
Auto-locks warn you of low batteries well in advance, and most include a USB-C emergency power port so you can briefly energise the keypad with a power bank and unlock. There is also a mechanical key override as a final backup — store that spare key somewhere outside the flat, such as with a trusted neighbour or family member.
Do auto door locks work well on HDB fire-rated doors?
Yes, provided you use an authorised installer who fits the lock without compromising the fire-rated door’s integrity. Most mortise auto-locks are designed for standard HDB and condo main doors; for a thin metal HDB gate you need a slim rim/gate-specific model instead.
Can I unlock an auto door lock with my phone?
Many app-connected models let you unlock via Bluetooth when nearby, and Wi-Fi-enabled versions allow remote unlocking and entry logs from anywhere. If remote access is not essential, an offline lock with PIN, card and fingerprint is simpler and has fewer connectivity worries — decide based on how often you need to let people in while away.
How long do the batteries last on an auto door lock?
Typical rechargeable or AA battery packs last several months to about a year depending on how often the lock is used and which features are active. Frequent fingerprint scanning and Wi-Fi shorten this, while a mostly PIN-based household stretches it — either way, the low-battery alert gives you plenty of notice to recharge or swap batteries.
