A smart lock is the scariest upgrade a renter can attempt. Lights and plugs are low-stakes — if something goes wrong, you’re in the dark. A lock is the thing standing between your apartment and everyone else. Add the landlord to the equation (it’s their door, their deadbolt, their security deposit), and it’s no wonder most renters never touch the front door.
But the lock is also the upgrade renters benefit from most. No more hiding a spare key under the mat, no more panicking when a roommate loses theirs, no more rushing home to let in the dog walker. And in 2026, three brands make locks genuinely suited to rental life: August, Schlage, and Yale. Each takes a different approach to the renter’s core problem — how do you upgrade a lock you don’t own?
This is a head-to-head comparison of the three brands’ most renter-friendly options: the retrofit August Wi-Fi Smart Lock (4th Gen), the keypad deadbolt Schlage Encode Plus, and the key-free Yale Assure Lock 2. We’ll cover how each installs in a rental, what each demands of your landlord’s hardware, and which one wins for different renter profiles.
What renters should look for in a smart lock
Retrofit vs. deadbolt replacement
This is the single most important distinction. Retrofit locks (August) attach to the inside of your existing deadbolt. The outside of your door doesn’t change at all, your existing keys keep working, and your landlord’s hardware is never removed. Replacement locks (Schlage Encode Plus, Yale Assure Lock 2) swap out the deadbolt itself — but crucially, they use the existing bore holes and strike plate. No new drilling, no new holes. A competent renter can do the swap with a screwdriver in 20–30 minutes.
The renter’s rule for replacement locks: photograph and safely store the original lock, and reinstall it before move-out. Keep every screw. This is what makes a replacement lock deposit-safe.
Keypad vs. app-only
App-only locks (August, without its keypad accessory) are fine if you always have your phone. Keypad locks (Schlage, Yale) are better for households: roommates, partners, dog walkers, and cleaners each get their own code, and nobody needs an app account or a charged phone to get in.
Built-in Wi-Fi vs. hub/bridge
Remote access — locking the door from work, getting an alert when the kids get home — requires the lock to reach the internet. All three locks compared here have built-in Wi-Fi (August Wi-Fi 4th Gen, Schlage Encode Plus, and the Wi-Fi version of the Yale Assure Lock 2), so there’s no extra hub to buy or plug in. Be careful when shopping: cheaper Bluetooth-only versions of these locks exist and need a separate bridge for remote features.
Battery life and lockout protection
All three run on standard batteries (typically AAs) and warn you well before they die. Your lockout plan matters: August keeps the original key cylinder, so a dead battery just means using your key. Keypad locks like Schlage and Yale include terminals on the bottom where you can hold a 9V battery to power the keypad long enough to enter your code.
The landlord conversation
Get written permission before swapping a deadbolt, even a reversible one. Frame it as a security upgrade (it is — you’ll know exactly who has access and when), offer to share a code or key, and confirm in writing that you’ll restore the original hardware at move-out. August’s retrofit design usually needs no permission conversation at all, since the landlord’s lock stays exactly where it is.
Head to head: the three contenders
August Wi-Fi Smart Lock (4th Gen) — Best retrofit for renters
August takes the path of least resistance: instead of replacing your deadbolt, the August Wi-Fi Smart Lock bolts onto the inside thumb-turn of the lock you already have. Installation takes about ten minutes with a screwdriver, the outside of your door looks identical, and your existing keys keep working. For renters, this is the closest thing to a zero-risk smart lock — the landlord’s hardware is never touched.
Feature-wise, it’s a full smart lock: built-in Wi-Fi (no bridge needed), auto-unlock as you approach, auto-lock when you leave, and DoorSense, which tells you whether the door is actually closed or just locked. It works with Alexa, Google Assistant, and Apple HomeKit. The main compromises: there’s no keypad in the box (August sells one separately), so guests need the app or your key; and August’s app, while much improved, has historically been the least polished of the three.
- Key specs: Retrofit design (keeps existing deadbolt and keys); built-in Wi-Fi; auto-unlock/auto-lock; DoorSense open/closed detection; works with Alexa, Google Assistant, HomeKit; optional keypad accessory.
- Pros: Easiest, most landlord-proof installation; your keys still work as backup; no exterior change to the door; strong auto-unlock.
- Cons: No keypad included; relies on the quality of your existing deadbolt; app experience trails Yale and Schlage.
Schlage Encode Plus — Best for Apple Home Key
The Schlage Encode Plus is the heavyweight of the three — literally, and in terms of features. It’s a full deadbolt replacement with a touchscreen keypad, built-in Wi-Fi, and support for up to 100 access codes, so every roommate, dog walker, and guest can have their own. Its headline feature is Apple Home Key: tap your iPhone or Apple Watch to the lock and you’re in, even if your phone is dead (power reserve mode). It also works with Alexa, Google Assistant, and HomeKit, and carries a BHMA/ANSI Grade 1 residential rating — the highest standard for lock strength.
For renters, the trade-off is the installation: this replaces your deadbolt, so you’ll need your landlord’s written okay and you must store the original lock for move-out day. It’s also the priciest of the three. But if anyone in your household lives on an iPhone, nothing else matches the convenience of Home Key.
- Key specs: Deadbolt replacement (uses existing bore holes, no new drilling); built-in Wi-Fi; touchscreen keypad with 100 codes; Apple Home Key support; BHMA Grade 1; works with Alexa, Google Assistant, HomeKit.
- Pros: Apple Home Key is genuinely the best phone-unlock experience; robust keypad for households; highest security rating; no hub needed.
- Cons: Replaces the deadbolt (store the original!); highest price of the three; larger and heavier than the competition.
Yale Assure Lock 2 (Key-Free Keypad, Wi-Fi) — Best app and keypad experience
The Yale Assure Lock 2 takes a bold approach: there’s no key cylinder at all. Nobody can pick, bump, or copy a key for this lock — access is by touchscreen keypad, app, or voice assistant. The Wi-Fi version connects directly to your network with no bridge, and the Yale Access app is widely considered the best-designed lock app of the three, with easy guest access, schedules, and auto-lock that actually locks reliably.
Going key-free is liberating until your batteries die, so Yale includes 9V jump terminals on the bottom of the keypad — hold a 9V battery to it and you can punch in your code. Like the Schlage, this is a deadbolt replacement using your door’s existing holes, so plan on landlord permission and storing the original hardware. Yale also sells keyed versions if the key-free concept makes you nervous, but the key-free model is the cleanest fit for the keyless lifestyle most smart-lock buyers want.
- Key specs: Key-free deadbolt replacement (existing bore holes, no new drilling); touchscreen keypad; built-in Wi-Fi; 9V emergency jump terminals; auto-lock; works with Alexa, Google Assistant, HomeKit (Wi-Fi model).
- Pros: No key to lose, copy, or pick; best-in-class app; keypad is great for households; no hub or bridge.
- Cons: No physical key backup; replaces the deadbolt (keep the original for move-out); make sure you buy the Wi-Fi version, not Bluetooth-only.
August vs Schlage vs Yale: comparison summary
Installation risk: August wins by a mile — nothing of the landlord’s is removed or altered. Schlage and Yale tie for second: both are reversible deadbolt swaps that reuse existing holes, which is deposit-safe as long as you reinstall the original.
Getting in without your phone: Schlage and Yale win with their keypads (and August has a physical key). August without its keypad accessory is the weakest here — guests need the app.
Smart home integration: All three cover Alexa, Google, and HomeKit. Schlage pulls ahead for iPhone users with Apple Home Key; Yale has the best app experience; August’s auto-unlock is the most hands-free.
Security hardware: Schlage’s Grade 1 rating leads. Yale’s key-free design eliminates key-based attacks entirely. August is only as strong as the deadbolt it retrofits — fine in most rentals, but worth noting.
Verdict: which lock for which renter?
- Best for the budget-conscious renter: August Wi-Fi Smart Lock. It’s typically the most affordable of the three, the install is trivial, and there’s no keypad to buy.
- Best for iPhone / Apple Watch users: Schlage Encode Plus. Apple Home Key alone justifies it — tap to unlock, even with a dead phone battery.
- Best app experience: Yale Assure Lock 2. The Yale Access app is the easiest for managing guests, schedules, and notifications.
- Best “landlord-proof” option: August. No permission needed in most cases, since the existing lock stays put.
- Best for households and roommates: Schlage Encode Plus or Yale Assure Lock 2 — both give everyone their own code, and you’ll know exactly who came home when.
- Best if you want to keep using a physical key: August (your keys keep working) or Schlage (keyed keypad deadbolt).
Renter installation tips (all three locks)
First, check your door: all three need a standard single-cylinder deadbolt setup — a separate deadbolt above the doorknob, which is what most US apartments have. Measure your door’s thickness and backset; all three fit standard US doors, but very thick or very thin doors can need adapters.
For August, installation is ten minutes on the inside of the door — remove the thumb-turn plate, mount the August, done. For Schlage and Yale, set aside 20–30 minutes and a Phillips screwdriver: remove the old deadbolt (photograph it first, screws and all), install the new one in the same holes, and put the original in a labeled box with its screws taped inside. When you move out, reverse the process.
Finally, test everything before you need it: every code, auto-lock timing, and the 9V jump procedure on keypad models. And give your landlord a code or a key — many leases require the property owner to have access, and it’s the right thing to do regardless.
Smart lock FAQ for renters
Will a smart lock violate my lease?
It depends on the lease, so read yours and get written permission before replacing a deadbolt. August’s retrofit design rarely raises issues since the landlord’s lock is untouched. For Schlage and Yale, emphasize that the swap is fully reversible and that you’ll restore the original hardware at move-out.
Can my landlord demand access?
In most jurisdictions, landlords retain a right of access with proper notice, and your lease may require you to provide a key. With August or Schlage, hand over a physical key copy. With the key-free Yale, provide the landlord with their own entry code in writing.
What happens if the batteries die while I’m out?
August: use your physical key — it still works. Schlage and Yale: hold a 9V battery to the terminals under the keypad to power it temporarily, then enter your code. All three warn you in the app well before batteries run low.
Do I need strong Wi-Fi at my front door?
For remote features (locking from work, entry alerts), yes — the lock needs to reach your Wi-Fi. Front doors are often far from the router in apartments; if your signal is weak there, a Bluetooth model paired with a bridge closer to the door, or a small Wi-Fi extender, solves it. Basic locking/unlocking at the door works over Bluetooth regardless.
Can I take the smart lock when I move?
Yes. August pops off in minutes. Schlage and Yale uninstall with a screwdriver — just reinstall the original deadbolt you carefully stored, and the door is exactly as you found it.
The bottom line
There’s no single winner — there’s a winner for your situation. August is the renter’s safest bet: nothing changes, your keys still work, and installation is nearly foolproof. Schlage Encode Plus is the pick for iPhone households that want the best unlock experience and a serious keypad. Yale Assure Lock 2 is for renters who want to go fully keyless with the best app in the business. Whichever you choose, get the landlord’s okay in writing, keep the original hardware, and you’ll get your deposit back with a smarter front door to show for your lease.
