Short answer: for an apartment, get the SwitchBot Lock Pro at $119.99. It clamps over your existing deadbolt with no drilling, no new holes and nothing for the landlord to object to — and it comes off clean when you move out. If the budget is the priority, the Wyze Lock Bolt at $74.98 gives you fingerprint and keypad entry for less than half the price, but it swaps the whole deadbolt, so you need the landlord’s permission first. Pick by install type first, then by who needs a code, then by whether you need remote access — and the rest of this guide shows you how.

What actually matters in a smart lock for an apartment?
Three things decide it, and price is only the third. First, install: a retrofit lock clamps over your existing deadbolt and leaves no marks, while a replacement deadbolt means removing the landlord’s hardware — you need written permission first, and you must keep the original to put back. Second, deposit safety: whatever you install has to come off cleanly when you move, with the door exactly as you found it. Third, who needs in: roommates, a cleaner, a dog walker — a keypad or app codes beat handing out copies of a key, and being able to revoke one person’s code without changing everyone else’s is what makes a smart lock worth it in a shared flat. Only after those three do you compare prices — and remember the all-in cost: a $119.99 lock that needs a $69.99 hub is a $189.98 lock.
Which affordable smart lock is best overall for apartments?
The SwitchBot Lock Pro at $119.99 on SwitchBot’s US store. It is the most apartment-proof pick here: it clamps over your existing deadbolt’s thumb-turn, so the outside of the door does not change at all, your existing key still works, and the landlord’s hardware is never touched. It runs on 4 AA batteries for 6 to 9 months, and it works over Bluetooth out of the box. Add the Keypad Touch and it becomes a fingerprint-and-code lock — the Lock Pro plus Keypad Touch bundle is $169.99 on SwitchBot’s store. Add a Hub 2 ($69.99) instead and you get remote access and Matter support for $189.98 all-in — still under $200 either way. If you want the full no-drill picture, our guide to the best smart lock for renters no drill covers retrofit locks in detail, including which cylinders each one fits.
What is the cheapest smart lock that still feels good?
The Wyze Lock Bolt at $74.98 on sale ($79.98 list) on wyze.com. For that money you get fingerprint unlocking (up to 50 prints), a backlit keypad, an ANSI Grade 2 deadbolt and auto-lock — the cheapest fingerprint deadbolt from a major brand, and the lowest price in this guide by a wide margin. The trade-off is the install: it is Bluetooth-only, with no Wi-Fi and no remote access, and it is a full deadbolt replacement, not a retrofit — so a renter needs the landlord’s say-so before swapping the hardware, and must keep the original deadbolt safe to reinstall at move-out. It also has a handy escape hatch if the batteries die: a USB-C port on the keypad gives it a brief charge so you can enter your code. For a flat where the budget matters more than remote access, it is the best value here.
What is the cheapest Apple Home Key lock for an apartment?
The Aqara Smart Lock U50 at $149.99 on Aqara’s US store. It is the cheapest way into an Apple Home Key lock: tap your iPhone or Apple Watch on it to unlock, even when the phone is out of battery, plus a keypad, NFC cards and a physical key. It can also be re-keyed to work with your existing key — a genuinely useful apartment feature, since the landlord’s key keeps working. The catches are honest ones: it is a full deadbolt replacement, so you need the landlord’s permission and must keep the original hardware; there is no fingerprint reader; and remote access needs an Aqara Zigbee hub — the U50 plus Hub M100 bundle is $152.99, only $3 more than the lock alone. Battery life is up to 6 months on 4 AA batteries, and there is a USB-C emergency port if they die. For an Apple household in a flat, it is the cheapest Home Key door you can buy.
Which lock gives you Wi-Fi with nothing extra to buy?
The Nuki Smart Lock (Deadbolt) at $159 on Nuki’s US store. It is the only pick here with Wi-Fi built in at this price, so remote access costs nothing extra — no hub, no bridge. You can create up to 200 individual access permissions, each with its own time limits, which is exactly what a shared flat needs: one code per roommate, revoked when someone moves out. It installs on the inside of the door without drilling, and Nuki’s own guidance says it is ideal for rented apartments because it can be removed without leaving marks. The rechargeable battery charges on the door in about two hours. This is the US deadbolt model — not the Smart Lock Ultra, which is a Euro Profile cylinder lock sold in Europe only and never the US price.
Which lock sits exactly at the $200 cap?
The August Wi-Fi Smart Lock at $199.99 on August’s US store. It is the other true retrofit here: it fits over your existing deadbolt, keeps your key working, and has Wi-Fi built in, so there is no bridge to buy. DoorSense tells you whether the door is actually closed, auto-lock handles the roommate who forgets, and the activity log records every entry. August’s own FAQ answers the apartment question directly: the lock fits without changing the deadbolt or needing a different set of keys, so your landlord still has full access to the apartment. The catch is the keypad: there is none on the lock itself, so codes mean buying the Yale Keypad separately — which pushes a code-based setup over $200. Buy August when the household unlocks by phone and app; buy SwitchBot or Nuki when you need codes for roommates.
How do you handle roommate codes and moving out?
Give every person their own code and keep one master code that only you know. On an app lock (Nuki, August, SwitchBot with a hub), you create and revoke codes from your phone — when a roommate moves out, revoke their code and the old one stops working the same day. On a keypad-only setup, change the shared code on the keypad itself. At move-out, a retrofit lock comes off in minutes: unclamp it, put the thumb-turn back, and the door is exactly as you found it. A replacement deadbolt takes more care: reinstall the landlord’s original deadbolt before you hand the keys back, and keep it somewhere safe for the whole tenancy — losing it comes out of your deposit. If you host short stays rather than long lets, our Airbnb smart lock guide covers guest codes, check-in windows and remote access in detail.

Frequently asked questions
Can I install a smart lock in an apartment without drilling?
Yes — retrofit locks clamp over your existing deadbolt and leave no marks. The SwitchBot Lock Pro, Nuki Smart Lock (Deadbolt) and August Wi-Fi Smart Lock all install on the inside of the door without drilling. Check the lease first anyway: some landlords still want to approve any lock change, even a reversible one.
Will my landlord allow a smart lock?
Usually yes for a retrofit, because nothing changes on the outside of the door and the landlord’s key still works — August’s own FAQ says the landlord keeps full access to the apartment. A replacement deadbolt is different: it swaps the landlord’s hardware, so get written permission first and keep the original deadbolt safe to reinstall when you move out.
What is the best affordable smart lock for apartments?
The SwitchBot Lock Pro at $119.99 for most renters — a no-drill retrofit that comes off clean at move-out. If the budget is the priority and you can swap the deadbolt with permission, the Wyze Lock Bolt at $74.98 covers fingerprint and keypad entry for less than half the price.
What if my apartment door has no deadbolt?
Every pick in this guide needs a standard single-cylinder deadbolt, which most US apartment doors have. If your door only has a knob or lever and no deadbolt, you need a lever smart lock instead — the Aqara U300 is a lever lock at $229.99, over this guide’s budget. Check your door first, and ask the landlord before changing a handle.
Can I take the lock with me when I move?
With a retrofit lock, yes — unclamp it in minutes and the door is exactly as you found it. With a replacement deadbolt, you can take the smart lock, but you must reinstall the landlord’s original deadbolt before you hand the keys back, so keep it somewhere safe for the whole tenancy.
Do I need Wi-Fi in my apartment building for a smart lock?
No — keypad and Bluetooth locks work without it. Wi-Fi (or a hub) only matters for remote access: changing codes or checking the lock from anywhere else. What counts is your own flat’s Wi-Fi, not the building’s — shared building Wi-Fi that needs a login page can block some locks, so use your own network for the lock.
That is the shortlist: five locks, one for every flat. If you only buy one, make it the SwitchBot Lock Pro at $119.99 — it is the only pick here that is a no-drill retrofit, deposit-safe and under $120 at the same time, with nothing extra you must buy.
