The SwitchBot smart lock is a clever option for Singapore renters and homeowners who want app and fingerprint entry without replacing their existing lock, and this guide walks through SwitchBot’s full lock line-up so you can match the right model to your door. SwitchBot’s retrofit design fits over the inside of many existing deadbolts and gate locks, which makes it especially appealing in condos and rented units where you cannot alter the original hardware. We cover the standard Lock, the beefier Lock Pro and Ultra, and the keypad add-ons that turn any of them into a full PIN-and-fingerprint system.
We wrote this for buyers who want smart entry but need a reversible, tenant-friendly install, or who simply do not want to drill out a working lock. SwitchBot has a strong following in Singapore because it slots into a wider ecosystem of hubs, sensors and blinds, all run from one app. A retrofit lock is only as reliable as its fit, so we stress checking your existing thumb-turn and deadbolt against SwitchBot’s compatibility guide before buying. We judged each pick on install type, unlock methods, hub requirements, battery life, smart-home integration and SGD value. Lock prices move with bundle promotions, so treat every figure as an indicative range and confirm the latest price before you commit.
What to look for in Singapore
- Retrofit compatibility — check your existing deadbolt and thumb-turn against SwitchBot’s fit guide before buying.
- Unlock methods — the base lock is app and auto-unlock; add the keypad for PIN, fingerprint and card entry.
- Whether you need the SwitchBot Hub for remote unlocking, alerts and voice control away from home.
- Smart-home integration — Matter, Apple Home, Google Home and Alexa support via the hub.
- Battery type and life, since retrofit locks run on replaceable cells you will swap periodically.
- Suitability for HDB metal gates versus condo timber doors, as retrofit fit varies by hardware.
- Auto-lock and door-sensor features so the door secures itself after you leave.
- Local availability of the lock, keypad and hub, plus warranty support in Singapore.

The picks
Editor’s Choice
SwitchBot Lock Pro + Keypad Touch
The Lock Pro paired with the Keypad Touch is the SwitchBot combo most Singapore buyers should get, adding fingerprint, PIN and card entry to a retrofit design that leaves your existing lock intact. It is faster and stronger than the original Lock, and the keypad means you are not tied to your phone. Ideal for condos and rented units.
Pros
- Retrofit, no drilling needed
- Fingerprint, PIN and card entry
- Works with wider SwitchBot system
Cons
- Hub needed for remote access
- Fit must be verified first
Premium
SwitchBot Lock Ultra
The Lock Ultra is SwitchBot’s top retrofit lock, with faster unlocking, longer battery life and native Matter support for cleaner smart-home integration. It is the pick if you want the most polished retrofit experience and plan to run it across Apple Home, Google or Alexa. Pricier, but noticeably slicker in daily use.
Pros
- Fast, quiet unlocking
- Long battery life
- Native Matter support
Cons
- Highest price in the range
- Keypad still a separate buy
Best Value
SwitchBot Lock (standard) + Keypad
The original SwitchBot Lock with a keypad is the budget route into retrofit smart entry, covering app and PIN unlocking for less. It is a little slower than the Pro and Ultra but does the core job on a compatible deadbolt. A sensible starting point for renters testing the water.
Pros
- Lowest-cost retrofit option
- App and PIN entry
- Reversible, tenant-friendly
Cons
- Slower than Pro/Ultra
- Shorter battery life
Best add-on
SwitchBot Hub 2 / Hub Mini
The SwitchBot Hub is what unlocks remote control, away-from-home alerts and voice assistants for any SwitchBot lock, and the Hub 2 doubles as a temperature and humidity display. If you want to check or open your door while out, this is essential. It also bridges the rest of your SwitchBot devices to Matter.
Pros
- Enables remote lock control
- Voice and Matter bridge
- Hub 2 adds climate sensing
Cons
- Extra cost on top of lock
- Another device to place
The verdict
For most Singapore renters and condo owners the SwitchBot Lock Pro with a Keypad Touch is the best retrofit pick, while the Lock Ultra is worth the premium for the slickest experience.
Frequently asked questions
Does the SwitchBot lock replace my existing lock?
No — SwitchBot locks are retrofit, fitting over the inside of a compatible deadbolt so your original lock and keys still work. This makes them ideal for condos and rented units where you cannot alter the hardware. Always check compatibility with your thumb-turn first.
Do I need the SwitchBot Hub?
For local app unlocking and PIN entry via the keypad, no. But for remote unlocking, away-from-home notifications and voice assistants, you need a SwitchBot Hub to bridge the lock to the internet. Most people who want full smart features add one.
Will a SwitchBot lock fit an HDB gate or door?
It depends entirely on your existing lock. SwitchBot works best on standard deadbolts with a compatible thumb-turn, so check your specific HDB door or metal gate against the fit guide. Some setups will not accept a retrofit lock.
How long does the battery last on a SwitchBot lock?
Battery life varies by model and usage, but the Pro and Ultra last longer than the standard Lock, typically several months per set of cells. The app warns you before they run low, and swapping is quick and tool-free.
Is SwitchBot secure enough for a main door?
SwitchBot leaves your original mechanical lock in place, so physical security is unchanged while adding convenient smart entry. Use auto-lock and a strong PIN, keep the hub firmware updated, and the setup is well suited to everyday Singapore homes.
