The Lockin smart lock has become a popular digital lock choice in Singapore for HDB and condo owners who want fingerprint, PIN, card and app entry at a competitive price, and this guide walks through Lockin’s actual lineup so you can pick the right model for your door. Lockin builds full-body push-pull and mortise locks as well as models with 3D face recognition and palm-vein scanning, giving buyers a range of unlock options beyond the basics. We cover how the main Lockin families compare on entry methods, connectivity and fit, and where they sit against rivals like Kaadas, Yale and Aqara.
We wrote this for buyers comparing Lockin with the more established Singapore lock brands, particularly those who want lots of unlock methods for the money. Lockin has gained traction here through online retailers and installers, often undercutting big names while offering fingerprint reliability and app features most households actually use. As always, a digital lock is only as good as its installation, so we stress confirming that your chosen model fits your specific HDB fire-rated door or gate before committing. We judged each pick on unlock methods, door compatibility, app and connectivity, battery life and SGD value including installation. Lock prices shift with promotions, so treat every figure as an indicative range and confirm the latest quote before buying.

Frequently asked questions
Is Lockin a good smart lock brand for Singapore homes?
Lockin offers a wide range of unlock methods — fingerprint, PIN, card, and on premium models face and palm recognition — often at lower prices than established names. Fingerprint reliability is generally good. As with any lock, buy from a reputable local seller who confirms fit and offers warranty support.
Will a Lockin lock fit my HDB door?
Many Lockin models fit common HDB fire-rated doors, but you must confirm door thickness and mortise dimensions before buying. Setups vary, and some doors and gates need adapters, so have the seller or installer verify compatibility to avoid returns.
How does Lockin compare to Kaadas or Yale?
Lockin typically undercuts Kaadas and Yale on price while offering comparable or more unlock methods, including advanced biometrics on premium models. The established brands may have longer local track records and service networks, so weigh price against after-sales support.
Can I unlock a Lockin lock remotely?
Some Lockin models support remote access through a Wi-Fi bridge or gateway, letting you grant entry or check status from your phone. Confirm the specific model’s connectivity before buying if remote features and away-from-home PIN sharing matter to you.
What happens if the battery dies?
Lockin locks warn you well before the battery runs flat, and most include a USB-C emergency power port so you can unlock and recharge if it does die. Many also retain a physical key or card backup for peace of mind.
