The Apartment Smart Lock Problem
Landlords say no to replacing locks. Leases prohibit modifications. Move-out inspections demand original hardware. Yet you still want keyless entry, remote access, and the ability to let friends in without hiding keys under doormats.
Traditional smart locks replace your entire deadbolt. That's a non-starter for renters. But several smart locks install without removing existing hardware, leaving your apartment completely reversible when you move.
This guide covers five options that work for apartments, from $100 retrofit devices to $250 premium solutions. All install in under 30 minutes, require no drilling, and restore to original condition in minutes.
What Makes a Lock Apartment-Friendly?
Non-destructive installation: No drilling into door or frame
Reversible: Remove it completely when you move
Keeps existing keys: Landlord's keys still work
No exterior changes: Outside looks completely normal
Portable: Take it to your next apartment
The best apartment locks install on your deadbolt's interior side only. The exterior remains unchanged—your landlord's master key works exactly as before.
Top 5 Smart Locks for Apartments
1. August WiFi Smart Lock (4th Gen) — Best Overall
Price: $230
Installation: Interior only, no exterior changes
Battery: 4-6 months (4 AA)
August invented the retrofit smart lock category. The 4th generation perfects it.
How it works: The lock mounts over your existing interior deadbolt. Your current key works from outside. August rotates the thumb turn electronically from inside. Takes 10 minutes to install with included adapter plates.
Key features:
- •Auto-lock when door closes
- •Auto-unlock when you approach (phone location)
- •Works with DoorSense (detects open/closed)
- •WiFi built-in (no bridge needed)
- •Activity log shows who entered and when
Why it's apartment-perfect: Nothing changes on the outside. Landlords literally cannot tell you've installed anything unless they enter your apartment. Master keys work identically. Uninstall in 5 minutes when moving—your door looks factory-fresh.
Limitations: Bulky interior profile. Requires 4 AA batteries. Auto-unlock occasionally triggers early/late (phone GPS isn't precision-accurate).
Best for: Renters who want full smart lock features without any exterior modifications.
2. Level Lock+ — Most Invisible
Price: $330
Installation: Replaces interior lock mechanism
Battery: 1 year (CR2 battery)
Level Lock does something remarkable: it's completely invisible. The entire smart mechanism fits inside your existing deadbolt. From inside, your lock looks like a normal lock. No visible tech whatsoever.
How it works: Remove your lock's interior mechanism. Install Level's mechanism in the same space. It looks and operates like a normal lock, but connects to your phone via Bluetooth. An optional $50 bridge adds remote access.
Key features:
- •Completely invisible from both sides
- •Works with Apple HomeKit natively
- •Touch-to-lock convenience
- •One-year battery life
- •Premium build quality
Why it's apartment-perfect: Nobody knows you have a smart lock. Not neighbors, not landlords, not inspectors. It looks like standard builder-grade hardware.
Limitations: Expensive. Bluetooth-only without optional bridge ($50). Setup is slightly more involved than August. Currently works best with iPhones.
Best for: Apple users who prioritize aesthetics and want zero visible smart home tech.
3. Yale Assure Lock 2 (Retrofit Kit) — Best Features
Price: $280
Installation: Interior only
Battery: Up to 12 months
Yale's Assure Lock 2 with retrofit kit gives you keypad access without exterior changes. The keypad mounts on the interior, leaving your exterior completely standard.
How it works: Similar to August—mounts over existing deadbolt interior. Adds a keypad on the inside, which seems backwards until you realize it prevents visible exterior modifications that violate leases.
Key features:
- •Matter certified (works with everything)
- •Backlit keypad with 250 user codes
- •Auto-lock and unlock
- •Tamper alerts
- •WiFi module included
Why it's apartment-perfect: Get keypad convenience without exterior changes. Create temporary codes for dog walkers, cleaners, or Airbnb guests (if allowed). Delete codes instantly when people leave.
Limitations: Interior keypad placement feels odd initially. More expensive than August. Battery life varies with usage.
Best for: People who want keypad access and maximum compatibility (Matter support).
4. Wyze Lock — Budget Champion
Price: $95
Installation: Interior only
Battery: 4-6 months (4 AA)
Wyze makes absurdly affordable smart home devices that punch above their price point. The Wyze Lock costs $95 and does 90% of what August does.
How it works: Retrofit installation identical to August—mounts over interior deadbolt. No exterior changes. Connects via Wyze Gateway (included) for remote access.
Key features:
- •Auto-lock and unlock
- •Works with Alexa and Google Assistant
- •Guest access codes
- •Activity log
- •Included gateway for remote access
Why it's apartment-perfect: Same retrofit approach as August for 60% less money. Excellent for trying smart locks without major investment.
Limitations: Wyze app less polished than competitors. Gateway required for remote access (included but another device to plug in). Customer support slower than major brands.
Best for: Budget-conscious renters wanting to test smart locks before committing to premium options.
5. Level Bolt — Minimalist Option
Price: $130
Installation: Interior mechanism replacement
Battery: 1 year (CR2)
Level's entry option. Less features than Level Lock+, but same invisible installation and significantly cheaper.
How it works: Replaces interior lock mechanism like Level Lock+. Bluetooth-only (no bridge option). Simple lock/unlock via phone. That's it.
Key features:
- •Completely invisible installation
- •Bluetooth control
- •Touch-to-lock
- •Year-long battery
- •Works with HomeKit
Why it's apartment-perfect: Invisible smart lock at half the price of Level Lock+. Perfect for people who only need basic remote lock/unlock.
Limitations: Bluetooth range only (~40 feet). No auto-unlock. No auto-lock. No remote access. No guest codes. Very basic functionality.
Best for: Minimalists who want invisible tech and only need occasional phone-based lock/unlock.

Lease-Friendly Considerations
Check Your Lease for These Clauses:
"No lock modifications": Retrofit locks don't modify locks—they attach to them. But confirm with landlord.
"Must provide landlord with keys": Explain that landlord's existing keys work unchanged.
"No permanent installations": These qualify as temporary—completely reversible.
"No drilling/damage": These use existing screw holes only.
Most landlords approve retrofit locks when you explain they're reversible and preserve master key access. Get written approval to avoid disputes.
Document Everything:
Before installation: Photograph your original lock from all angles.
After removal: Store original hardware safely. You'll need it when moving.
At move-out: Reinstall original hardware. Your door should look identical to move-in photos.
Real-World Apartment Use Cases
Case 1: Dog Walker Access
Problem: Dog walker needs entry while you're at work.
Solution: August or Wyze lock. Create temporary guest access code. Set access window (2-3 PM weekdays). Receive notification when walker enters/exits. Delete code when service ends.
Case 2: Frequent Travel
Problem: Need to let Airbnb cleaners in during stays (where allowed).
Solution: Yale Assure 2. Create unique codes for each guest/cleaner. Set expiration dates automatically. No physical key exchange needed.
Case 3: Hands-Full Situations
Problem: Arriving home with groceries, can't find keys.
Solution: August with auto-unlock. Lock detects phone proximity and unlocks as you approach. Walk straight in without stopping.
Case 4: Roommate Situations
Problem: Roommate keeps forgetting keys, buzzes for entry.
Solution: Any lock with guest codes. Give roommate their own code. Track who enters when via activity log.
Case 5: Security Concerns
Problem: Lost keys, worried someone might use them.
Solution: Smart lock eliminates key copying risks. Revoke phone access instantly if phone stolen. Change access codes remotely if needed.
What NOT to Buy
Standard Smart Locks (Not Retrofit):
August, Yale, Schlage, Nest all make excellent smart locks—that replace your entire deadbolt. These require landlord permission and leave permanent modifications.
DIY Smart Lock Kits:
Raspberry Pi and servo motor setups are fun projects but unreliable for daily security. Stick to commercial products for locks.
Keyless Entry Keypads (Standalone):
Keypads that mount to your door with adhesive or screws are visible modifications. Use interior-mounted options instead.
Common Questions
Q: Will my landlord's master key still work?
A: Yes, for August/Wyze/Yale retrofit models. Your exterior lock remains completely unchanged.
Q: What happens if batteries die?
A: Keys always work. Most locks warn you weeks before battery death. Keep spare batteries handy.
Q: Can I take the lock when I move?
A: Absolutely. That's the entire point. Takes 5 minutes to uninstall and reinstall original hardware.
Q: Will my door frame/hardware work?
A: August/Wyze include adapter plates for most common deadbolts. Check compatibility on manufacturer websites before buying.
Q: Do these work on double-deadbolt doors?
A: Most work on standard single-cylinder deadbolts. Double-cylinder locks (key on both sides) are trickier—check specific model compatibility.
Q: What about fire safety?
A: All these locks have manual override. You can always unlock from inside by turning the mechanism manually.
Security Considerations
Smart locks don't make your door more or less physically secure. Your deadbolt's physical security remains unchanged. Smart locks add:
More secure: Digital access logs, no lost keys to worry about, instant access revocation
Less secure: Potential for electronic failure, reliance on batteries, vulnerable to phone theft
Overall security is similar to traditional locks, with added convenience and access control benefits.
Budget Planning
Minimum viable: $95 (Wyze Lock)
Gets you basic smart lock functionality.
Recommended: $230 (August WiFi)
Best balance of features, reliability, ease of use.
Premium: $330 (Level Lock+)
Invisible installation, premium build, longest battery.
Add-ons:
- •Extra adapters (if moving frequently): $10-20
- •Backup batteries: $10
- •Smart home hub (if needed): $25-100
Installation Mistakes to Avoid
Mistake 1: Not checking deadbolt compatibility
Measure your deadbolt before buying. Most work with standard residential deadbolts, but confirm.
Mistake 2: Over-tightening screws
Especially with August/Wyze mounts. Over-tightening can strip threads or crack plastic adapters.
Mistake 3: Ignoring door alignment
If your door doesn't close smoothly now, a smart lock won't fix that. Adjust door alignment first.
Mistake 4: Relying solely on auto-unlock
Auto-unlock is convenient but not 100% reliable. Always test manual unlock before relying on automation.
Mistake 5: Forgetting to save original hardware
You'll need it when you move. Store in a labeled bag somewhere safe.
The Verdict
For most apartment renters: Get the August WiFi Smart Lock. It has the best feature set, works reliably, installs easily, and maintains good resale value if you upgrade later.
For iPhone users wanting invisible tech: Level Lock+ costs more but disappears completely. Worth it if aesthetics matter.
For budget buyers: Wyze Lock delivers 90% of August's functionality for $95. Excellent for testing whether you actually want a smart lock.
For keypad lovers: Yale Assure 2 with retrofit kit provides interior keypad access while maintaining exterior-invisible installation.
For minimalists: Level Bolt gives you basic smartphone unlock in invisible form factor for half the price of Level Lock+.
None of these require landlord approval in most cases (still check your lease). All install quickly, work reliably, and uninstall cleanly when you move. Start with one of these, not with researching which $400 smart lock to install permanently—you can't do that anyway.
