A smart lock for Airbnb or any short-term rental solves the biggest headache of hosting: handing over keys. With a good smart lock you issue each guest a time-limited PIN that works only during their stay, track who comes and goes, and never worry about lost keys or midnight meet-ups. While pure Airbnb-style short-term letting of private homes is tightly regulated in Singapore, the same locks are ideal for serviced apartments, co-living, rented rooms, cleaners and family access. This guide covers the best smart locks for rental and multi-user access here.
We wrote this for hosts, landlords and anyone who needs to grant temporary, controllable access without physical keys. Our picks favour brands with proven remote or offline PIN management, reliable logs and strong local support, led by igloohome, whose offline algorithmic PINs are purpose-built for rentals, alongside Yale, Kaadas and Aqara. We weigh how easily you can create and revoke guest codes, whether the lock needs constant Wi-Fi, access logging, battery reliability and the fallbacks that stop a guest, or you, ever being locked out.
What to look for in Singapore
- Time-limited PIN codes: the core feature for rentals, letting you issue a code valid only for a guest’s stay dates and revoke it after.
- Offline versus Wi-Fi code generation: offline algorithmic PINs (as igloohome uses) work without internet, sidestepping Wi-Fi dropouts at the property.
- Access logs: a record of who unlocked the door and when helps you verify check-ins, cleaner visits and any disputes.
- Remote management: for hosts who are not on-site, remote code creation via app or a bridge lets you manage access from anywhere.
- Battery reliability and alerts: a rental lock must never die on a guest, so prioritise clear low-battery warnings and an emergency power backup.
- Multiple codes and users: the ability to run many active codes at once suits back-to-back guests, cleaners and maintenance staff.
- Fallback access: a physical key or master override for you, plus a way for guests to get in if a code fails, prevents lockout disasters.
- Local support and compliance: buy a locally supported brand and ensure your letting arrangement complies with Singapore’s short-term accommodation rules.

igloohome is purpose-built for rentals and our top pick, generating time-limited PIN codes offline through a clever algorithm, so guests get in even when the property’s Wi-Fi is down.

As a Singapore brand with local support, it is the natural choice for hosts and landlords managing guest access.
Pros

Yale smart lock (with connectivity)
Yale’s connected smart locks let you manage temporary codes remotely through a bridge, backed by the brand’s proven reliability and wide local installer network. For hosts who value rock-solid hardware and easy after-sales support, it is a dependable premium option. Best when the property has stable Wi-Fi for the bridge.

Best all-rounder
Kaadas digital lock range
Kaadas locks support multiple codes and users in a robust body, making them a solid all-rounder for co-living, rented rooms or households juggling family, cleaners and helpers. They are feature-rich and well-built, though best bought through an authorised SG dealer. A dependable choice for busy multi-user doors.

Best for smart-home hosts
Aqara smart lock
For hosts already running an Aqara smart home, its smart lock ties guest codes and access logs into the wider ecosystem, enabling automations such as lights and aircon that react on entry. It is a neat fit where the whole unit is already Aqara-equipped. Best value comes as part of that ecosystem rather than standalone.
Pros
- Integrates with smart-home automations
- App-based codes and logs

Frequently asked questions
Is Airbnb-style short-term rental even legal in Singapore?
Short-term letting of private residential homes is tightly restricted here, with minimum-stay rules that effectively rule out nightly Airbnb in HDB and most private homes. These smart locks are still ideal for serviced apartments, co-living, rented rooms, cleaners and family access, so check the rules for your specific arrangement first.
Which smart lock is best for guest access?
igloohome is our top pick because it generates time-limited PIN codes offline, so guests get in even without Wi-Fi, and codes expire automatically after the stay. It also logs access, which is exactly what hosts and landlords need.
Can I manage codes remotely if I am not there?
Yes. igloohome lets you generate and send offline codes from anywhere, while Yale and Aqara offer remote management through a bridge or hub when the property has stable Wi-Fi. This means no in-person key handovers.
What if the Wi-Fi at the property is unreliable?
Choose a lock with offline code generation like igloohome, which does not depend on the property’s internet to create or validate guest PINs. Wi-Fi-only locks can leave guests stranded if the connection drops.
What stops a guest getting locked out?
Keep clear low-battery alerts, an emergency power backup and a master override or physical key for yourself. Reliable brands warn well before batteries die, and giving guests a simple fallback contact prevents lockout emergencies.
