The short answer: the August Wi-Fi Smart Lock (4th Gen) is the best smart lock for renters in 2026. It installs on the inside of your door over your existing deadbolt — no drilling, no exterior changes, and your landlord’s key keeps working. Setup takes about 10 minutes with a screwdriver, and built-in Wi-Fi means remote locking with no extra hub.
The key distinction for renters: retrofit locks (August, SwitchBot) attach to your current deadbolt and leave the outside of the door untouched, while replacement deadbolts (Schlage Encode, Wyze Lock Bolt) swap the whole lock. Retrofit is the lowest-drama option — and the one least likely to cost you your deposit.

1. August Wi-Fi Smart Lock (4th Gen) — best overall for renters
August invented the retrofit category and still leads it. The unit clamps onto the interior thumb-turn of your existing deadbolt using adapter plates in the box. From the hallway, your door looks completely unchanged — same handle, same keyhole, same key for your landlord.
Built-in Wi-Fi gives you full remote access through the August app with no bridge to buy or plug in: lock and unlock from anywhere, check the activity log, set auto-lock timers. DoorSense tells you whether the door is actually closed, not just whether the bolt is thrown. Auto-unlock uses your phone’s location to open the door as you approach, and guest access issues temporary digital keys from the app.
It works with Alexa, Google Home, and Apple HomeKit — the broadest compatibility of any retrofit lock. Battery life runs roughly 3–6 months on two CR123A batteries.
The honest limitation: there’s no keypad on the lock itself. Entry is by phone, voice, or your physical key. If you want PIN entry at the door, add August’s keypad accessory (sold separately).
2. SwitchBot Lock Pro — easiest install, best budget retrofit
If the idea of touching your deadbolt at all makes you nervous, the SwitchBot Lock Pro is the answer: it mounts with strong 3M adhesive over the interior thumb-turn. No tools, no screws, genuinely removable in seconds at move-out.
It’s the cheapest true retrofit option, and it pairs with SwitchBot’s keypad and fingerprint accessories if you want PIN entry. The catch: remote access and voice control need the SwitchBot Hub, sold separately — factor that into the total cost if you want to lock the door from work.
3. Aqara Smart Lock U200 — best for Apple Home and Matter
The U200 is the newer disruptor: a retrofit lock with a keypad included in the box, Matter-over-Thread support, and Apple Home Key compatibility — unlock with your iPhone or Apple Watch held near the lock. It installs over your existing deadbolt with no drilling.
Choose this if you’re building (or already live in) an Apple/Matter smart home and want the keypad convenience August charges extra for. The ecosystem is newer than August’s, so the app experience is less battle-tested.
4. Wyze Lock Bolt — cheapest smart lock with a keypad
The Lock Bolt is a full deadbolt replacement, not a retrofit — but it installs with just a screwdriver on standard doors and removes just as cleanly, which is why it keeps showing up in renter roundups. For under $100 you get a fingerprint reader, backlit keypad, auto-lock, and an anti-peep PIN feature.
It’s Bluetooth-only, so there’s no remote access or Wi-Fi control — you (or a guest) need to be near the door. But as a cheap, keyless, deposit-safe upgrade, nothing beats it on price.
5. Schlage Encode Smart WiFi Deadbolt — best premium full replacement
If your lease allows a full deadbolt swap and you want the most lock for the money, the Schlage Encode is it: built-in Wi-Fi (no hub), up to 100 keyless codes, a fingerprint-resistant touchscreen, and top-tier residential security certification. Installation is a genuine screwdriver job on standard doors.
Keep the original deadbolt in a drawer and reinstall it at move-out — that keeps the landlord conversation simple. It’s the priciest pick here, but also the most capable.
Renter checklist: before you buy any smart lock
Will my landlord care? Retrofit locks (August, SwitchBot, Aqara U200) don’t alter the exterior or the key, so most landlords never notice or object. Full replacements change the visible hardware — always check your lease first. This guide is buying advice, not legal advice.
Can I take it when I move? Yes to all five. Retrofit locks unclamp in minutes; replacement deadbolts unscrew the same way they went in. Keep the original hardware and put it back on move-out day.
What about the existing key? With retrofit locks, your current key keeps working exactly as before — good news if your landlord or building management needs access. Replacement deadbolts come with new keys, so you’ll need to hand copies to whoever needs them.
Battery life on a rental timeline: Most of these run 3–6 months per set of batteries — roughly two changes across a one-year lease. Set a calendar reminder; a dead lock at midnight is nobody’s idea of fun.
Frequently asked questions
Is the August lock renter friendly?
Yes — it’s the most renter-friendly smart lock you can buy. It installs entirely on the interior side of the door over your existing deadbolt, so the exterior, the keyhole, and your landlord’s key are all untouched. Removal takes minutes and leaves no trace.
What’s the best smart lock that doesn’t require drilling?
The August Wi-Fi Smart Lock (4th Gen) for the best all-round experience, or the SwitchBot Lock Pro if you want a tool-free stick-on install at a lower price. Neither requires drilling, and both are fully removable.
Can I install a smart lock in an apartment?
In most cases, yes. Retrofit locks need no permanent modification, so they rarely violate lease terms — but leases differ, so check yours (or ask your landlord) before installing anything. Battery-powered models need no wiring, which removes the other common objection. Pair it with a video doorbell for a complete renter-friendly entryway.
Do smart locks work if the power or Wi-Fi goes out?
Your physical key always works with retrofit locks, since the original deadbolt mechanism is untouched. Keypad models (Wyze Lock Bolt, Schlage Encode, Aqara U200) run on batteries independent of your home’s power, so codes keep working during an outage — you just lose remote access until Wi-Fi returns.
The bottom line
Buy the August Wi-Fi Smart Lock (4th Gen) if you want the safest, most proven renter pick — invisible from outside, no hub, no drilling. Buy the SwitchBot Lock Pro if you want the cheapest zero-tool install, or the Wyze Lock Bolt if a built-in keypad matters more than remote access. All five come off clean at move-out.
