Hands-on Review
The igloohome Deadbolt 2S is a clever offline-first deadbolt whose remote PIN codes work without any wiring or Wi-Fi — a standout for landlords and Airbnb hosts, if a deadbolt suits your door.
The igloohome Deadbolt 2S is a smart deadbolt lock from the Singapore-founded brand igloohome, built around PIN keypad and Bluetooth entry with its signature offline algoPIN codes that you can generate remotely and share without the lock ever touching the internet. It’s aimed at homeowners, landlords and short-stay hosts who want keyless access control that keeps working even when Wi-Fi doesn’t.
igloohome made its name on this offline approach, and the Deadbolt 2S is its accessible deadbolt option in a range that also includes mortise and padlock formats. In Singapore it competes with mainstream mortise locks from Kaadas, Lockin and Samsung, but it plays a slightly different game — its unique selling point is time-bound remote codes for rentals rather than push-pull luxury or deep smart-home automation.

Who it’s for
- Landlords and Airbnb/short-stay hosts who need remote, time-limited access codes
- Owners of doors suited to a deadbolt rather than a mortise lock
- Buyers who want offline reliability that doesn’t depend on Wi-Fi
- Skip it if your door needs a mortise lock body or you want push-pull convenience
- Skip it if you want deep Matter/HomeKit smart-home automation out of the box
Security & access control
The Deadbolt 2S is a proper motorised deadbolt with PIN and Bluetooth entry and a mechanical key backup. Where it pulls ahead is access management: the offline algoPIN system lets you issue one-time, duration-limited or recurring codes remotely and hand them to guests or cleaners, and the codes expire on their own — brilliant for rentals. Anti-tamper and jam alerts round out a sensible security picture.
Installation & door fit
As a deadbolt, the 2S fits doors set up for a single-cylinder deadbolt rather than the mortise bodies common on many Singapore main doors. This matters: some HDB and condo doors will need checking or won’t be ideal candidates, so confirm your door type first. Where it does fit, installation is relatively straightforward and doesn’t require running any wiring.
Offline codes & app
The igloohome app is the hub for generating algoPINs and Bluetooth unlocking, and the offline model is the whole point — you can grant access from anywhere without the lock being online, which sidesteps the reliability worries of Wi-Fi locks. For live remote monitoring, unlock logs and voice control you add the optional igloohome Bridge, so budget for that if you want a truly connected experience.
Battery & everyday living
On AA batteries the 2S runs up to around a year with low-battery warnings, and there’s a mechanical key as a final fallback. Under Singapore’s humidity the keypad held up well in sheltered use. Day to day it’s dependable, though the deadbolt form means a two-step entry (unlock, then push/pull the door) rather than the one-motion feel of a push-pull mortise lock.
Pros and cons
Pros
- Offline algoPIN codes are ideal for rentals and remote guest access
- Works without Wi-Fi, so no dependence on your router being up
- Singapore-founded brand with local availability and support
- Time-limited and one-time codes expire automatically
- Mechanical key backup and clear low-battery alerts
Cons
- Deadbolt format doesn’t suit every SG mortise-style main door
- Live remote monitoring needs the extra-cost igloohome Bridge
- Not a push-pull lock, so entry is a two-step motion
- Limited native Matter/HomeKit smart-home integration
Price in Singapore
In Singapore the Deadbolt 2S typically sells for around $250–$400, with the igloohome Bridge as a separate purchase if you want remote monitoring and voice control. It’s widely available locally through igloohome’s own channels and major retailers; check the latest price and whether a Bridge bundle works out cheaper.
Alternatives to consider
- Kaadas K9 — Pick it for a push-pull mortise lock that fits common local doors with strong installation support.
- Lockin V5 Max — Choose it for a more feature-rich connected lock if you don’t need offline rental codes.
- Aqara Smart Lock U200 — Better if you want Apple Home Key and Matter integration in an Apple-centric smart home.

Frequently asked questions
Is the igloohome Deadbolt 2S worth it?
If you’re a landlord or host who needs to grant remote, time-limited access, it’s excellent and hard to beat. For a standard owner-occupier wanting push-pull luxury, a mortise lock may suit better.
Will it fit my HDB or condo door?
It fits doors set up for a single-cylinder deadbolt, which isn’t every local main door. Check your door type before buying, as many SG doors are built around mortise lock bodies.
Do I need Wi-Fi for it to work?
No — that’s the point. Offline algoPIN codes and Bluetooth unlocking work without internet. You only need the optional igloohome Bridge for live remote monitoring and voice control.
How long does the battery last?
Roughly up to a year on AA batteries with low-battery alerts, plus a mechanical key backup so you’re never locked out if power runs down.
Is there local warranty and support?
Yes — igloohome is Singapore-founded with strong local availability and after-sales support, which is a solid reason to buy locally rather than grey-import.
The verdict
The igloohome Deadbolt 2S is a smart, purpose-built lock that solves the rental access problem better than almost anything else, thanks to offline codes that don’t rely on Wi-Fi. Its deadbolt format limits door compatibility and the best remote features cost extra via the Bridge, so it lands at 4.1 — outstanding for hosts, situational for everyone else.
