Digital locks have become almost standard on Singapore front doors, and Lockin is one of the brands that has gained a following among HDB and condo owners looking for a well-featured lock without paying the very top prices. The appeal is obvious: no more fumbling for keys with hands full of groceries, easy PIN access for family members, and the peace of mind of fingerprint entry. For our high-rise living, where a single main door is the primary security point, a solid digital lock is a sensible upgrade that also just makes daily life smoother.
That said, choosing a digital lock in Singapore is not just about features. It has to physically fit your door, which for HDB fire-rated doors and metal gates has specific requirements, and it needs reliable local installation and after-sales support. Lockin offers a spread of models from straightforward push-pull handle locks to app-connected smart locks. In this guide we look at what actually matters here: unlock methods, fit with HDB doors and gates, battery life and low-battery backup, and the security basics that keep your home safe without overcomplicating things.
What to look for in Singapore
- Confirm the lock fits your HDB fire-rated door and, if needed, the metal gate, ideally with a professional survey.
- Multiple unlock methods such as fingerprint, PIN, card, and app give flexibility for different family members.
- A fast, accurate fingerprint sensor matters for daily convenience, especially with our humid, sweaty hands.
- Reliable low-battery warnings and an emergency power option mean you are never locked out unexpectedly.
- Anti-peep or random PIN entry helps stop neighbours or passers-by from seeing your real code.
- App connectivity lets you check lock status and grant temporary access, useful for helpers or family.
- Auto-lock after closing ensures the door secures itself even when you forget in a hurry.
- Local warranty and installation support are essential so fitting and servicing are handled properly here.

The slim Lockin gate lock is designed to fit narrow metal gate frames, offering fingerprint and PIN entry so you can secure the gate without a physical key. It pairs neatly with a main-door lock for a full keyless setup. If your daily habit is locking the gate rather than the door, this is the piece you need.
Pros
- Slim fit for metal gates
- Keyless gate access
- Pairs with a main-door lock
Cons

For tech-forward homes that want the fullest feature set, the premium Lockin adds refined app control, robust auto-lock, and readiness to pair with a viewing camera or wider smart-home setup. It layers convenience features on top of solid security fundamentals, so you get remote status, detailed access logs, and easy temporary codes. It costs more, but for those who want their front door fully integrated and future-proofed, it delivers the most complete package.
Pros

- Robust auto-lock
- Smart-home ready
Cons

- More features to set up
The verdict
Lockin offers a sensible range that covers most Singapore front doors, and the app-connected model is the best all-round pick for convenience and control. Choose the push-pull for simple daily ease, or add the gate lock if securing the metal gate is your everyday habit.
Frequently asked questions
Will a Lockin digital lock fit my HDB fire-rated door?
Most Lockin models are designed to fit common HDB fire-rated doors, but the safest approach is a professional site survey before purchase. Door thickness, existing lock cut-outs, and whether you also want a gate lock all affect the fit. Buying through a local installer ensures the correct model and a proper installation that does not compromise your fire-rated door.
What happens if the battery dies while I am out?
Digital locks give repeated low-battery warnings well before they fail, so you normally have plenty of time to change the batteries. Many Lockin models also have an emergency power option, such as a terminal you can briefly power to unlock, plus a mechanical key backup on some versions. Keep spare batteries at home and you will rarely be caught out.
Is a fingerprint lock reliable in Singapore’s humidity?
Yes, modern fingerprint sensors work well even with slightly damp or sweaty fingers, which is a common concern in our climate. Registering the same finger a couple of times and keeping the sensor clean improves reliability further. If a fingerprint occasionally fails, you always have PIN, card, or app entry as a backup.
Can I give temporary access to a helper or family member?
On app-connected Lockin models you can create temporary or scheduled PIN codes, which is ideal for a domestic helper, cleaner, or visiting relatives. You can revoke the code afterwards without changing your own PIN. Non-connected models still let you add multiple fixed PINs and fingerprints for regular household members.
Is a digital lock secure enough for a Singapore home?
A reputable digital lock with anti-peep PIN entry, auto-lock, and tamper alerts is secure for typical high-rise living, where the main door and gate are the key points. Combining it with your existing metal gate adds another layer. As with any lock, professional installation and keeping your PIN private matter as much as the lock itself.
