How we reviewed it
A quick note on method, because it’s the honest thing to do: we don’t own a unit and we don’t run a lab, so nothing here is a hands-on test result. What we did was compile SwitchBot’s published specs and install design and read them through a renter’s lens — reversibility, deposit-safety, ongoing cost — the same way we’d judge any lock on this site. Where a claim is ours (like the lease-safe rating), we say so.
Install: adhesive over your thumb-turn, no drilling
This is the SwitchBot’s headline strength. It’s a retrofit, meaning it works with the deadbolt already on your door instead of replacing it, and it mounts with an adhesive base rather than screws. You clean the inside face of the door, stick the lock body on so it caps your existing thumb-turn, and it motorizes that turn to throw and retract the bolt. Nothing about the outside of the door changes, so your landlord’s hardware and your key both keep working, and there are no holes anywhere. At move-out the adhesive base comes off and the door is exactly as you found it. Compared with a lock that swaps the whole deadbolt, this is the more reversible path — our guide on fitting a smart lock over an existing deadboltexplains why that matters, and it’s worth a quick lease check before you change anything on a door. The one thing to confirm first is fit: adhesive mounting needs enough clearance around the thumb-turn and a compatible door thickness, so measure against the listing before you buy.
The keypad and hub add-ons — and what they cost you
Out of the box, the SwitchBot Lock unlocks over Bluetooth — great when your phone is in the apartment, less useful when you’re standing at the door with your hands full or trying to let someone in remotely. To close those gaps SwitchBot leans on add-ons, and this is where the cost and complexity creep in. A separate keypadadds code and fingerprint entry outside so guests don’t need your phone or a spare key, and it adhesive-mounts beside the door in keeping with the no-drill theme. Remote lock/unlock from anywhere and voice control, meanwhile, require the separate SwitchBot Hub. None of this needs a subscription — it’s all one-time hardware — but it does mean the “complete” SwitchBot setup is two or three purchases, not one. If a code pad is your main goal, our keypad smart locks roundup compares the options.
App and automation strengths
Where the SwitchBot pulls ahead is breadth. It lives inside a large ecosystem of sensors, keypads and app routines, so the lock can be one node in a wider setup rather than a standalone gadget — auto-lock on a schedule, tie-ins with other SwitchBot devices, that sort of thing. If you’re the kind of renter who enjoys building automations and wants room to grow, it’s the more expandable platform on this comparison. Just treat the account with the seriousness the hardware deserves: put a unique password and two-factor login on the app, exactly as the FTC recommends for any connected device that controls your home. A lock is only as secure as the login in front of it.
Batteries and everyday use
Day to day, the SwitchBot fades into the background, which is what you want from a lock. It runs on a battery — a rechargeable pack or AAs depending on the model — and warns you in the app well before it runs low, so you top it up on your own schedule rather than getting caught out. And because it’s a retrofit that leaves your deadbolt and key in place, a dead battery is never a lockout: you use the key you already carry while you recharge or swap cells. Auto-lock is the feature most renters lean on — set the door to relock itself after a delay and you stop second-guessing whether you locked up — and the SwitchBot does that locally over Bluetooth. Just remember the recurring theme of this review: watching or relocking the door from outside the apartment is the Hub’s job, not the lock’s alone. Set expectations there and the first week is uneventful in the good way.
Where it falls short
Two honest cons. First, price: the SwitchBot Lock is the most expensive option in this class by a wide margin, and that’s before you add the hub or keypad, so the all-in cost of a fully featured setup is higher still. Second, the hub dependency: the feature most people picture when they imagine a smart lock — unlocking it from somewhere other than the doorstep — isn’t there until you buy the SwitchBot Hub. Neither is a dealbreaker, but together they mean the SwitchBot rewards a renter who wants a system, and punishes one who just wanted a lock. If drilling was your only worry, note there are cheaper reversible retrofits too — our no-drill locks page rounds them up.
Who should buy it — and who should get the August instead
Buy the SwitchBot Lockif the screw-free adhesive install is a must-have, you want the widest ecosystem of keypads, sensors and automations, and you’re happy to add the Hub to reach remote control. For a lot of renters, though, the simpler August Wi-Fi Smart Lockis the smarter buy: it’s a keep-your-key retrofit too, it costs meaningfully less, and its Wi-Fi is built in, so remote lock/unlock and auto-lock work with no extra hub. The August isn’t flawless — it needs a compatible single-cylinder deadbolt, so check yours first, and a keypad is a separate accessory — but for the renter who wants keyless entry that just works without assembling a kit, it’s the easier recommendation.
