August smart lock installation is a common search among Singapore homeowners who have seen the popular US retrofit lock online, but the honest answer is that August does not suit most local doors — it is designed to fit over an American single-cylinder deadbolt, which HDB and condo doors do not use. This guide explains why, what to do if you already own one, and the locally supported smart locks that give you the same keyless convenience with proper installation and warranty here.
Rather than fake availability, we lead with the smart locks that genuinely fit Singapore doors and are installed by local professionals, so you get keyless entry, app control and after-sales support. Whether you were drawn to August for phone unlocking, remote access for guests, or auto-lock, these picks deliver those features on HDB gates and main doors — the practical route to a smart lock home in Singapore.
What to look for in Singapore
- Check door and lock compatibility first — August fits US deadbolts, which HDB and condo doors do not have, so choose a lock designed for local mortise or gate installation.
- Prioritise brands with local installers and warranty so fitting is done correctly and support is easy to reach.
- Decide which keyless features you actually want — fingerprint, PIN, card, app or auto-lock — and pick a lock that offers them.
- For remote guest access, look for locks with app control or offline PIN generation so you can let people in when away.
- Match the lock type to the door: slim rim/gate lock for a metal gate, mortise lock for a solid main door.
- Humidity and corridor exposure mean gate locks need weather-resistant casings; indoor main-door locks are less exposed.
- Confirm mechanical key override and a low-battery alert with USB-C emergency power to avoid lockouts.
- Compare SGD value including installation, and favour a lock you can service locally over an imported unit with no support.

Frequently asked questions
Can I install an August smart lock in Singapore?
In most cases no — August is designed to retrofit over a US-style single-cylinder deadbolt, which HDB and condo doors do not have. Rather than force an incompatible fit, choose a smart lock made for local mortise or gate doors, such as igloohome, Aqara, Kaadas or Yale, installed by a local professional.
I already own an August lock — what can I do?
Because it needs a compatible US deadbolt, it usually cannot be fitted to a standard Singapore door without unusual modification, which most locksmiths will not recommend. The practical path is to use a locally supported smart lock designed for your door and keep the August for a different property abroad.
Which smart lock gives August-like remote access here?
igloohome is the closest match — its offline algoPIN lets you generate time-limited codes for guests or cleaners remotely without Wi-Fi. Aqara’s U-series adds Apple Home Key phone unlocking. Both are installed and supported in Singapore, unlike an imported August.
Do I need professional installation for a smart lock?
For main-door mortise locks and gate rim locks, yes — professional installation ensures the lock aligns, seals and operates correctly, and it keeps your warranty valid. Local dealers assess your door type and fit the lock properly, which an imported retrofit kit cannot guarantee.
Are smart locks secure and reliable in Singapore’s climate?
Quality locks from established brands are built for our humidity, with sealed casings and mechanical key override as backup. Gate-rated models add weather resistance for open corridors. Choose a locally supported brand so servicing and spare parts are easy if you ever need them.
