Materials and Tools Needed
You'll need minimal gear—great for no-drill simplicity.
- Your chosen no-drill smart lock kit (e.g., August Wi-Fi Smart Lock, Schlage Encode Smart WiFi Lever, or Yale Assure Lock retrofit)
- Phillips screwdriver (usually size #2; included in some kits)
- Smartphone (iOS or Android) with Bluetooth/Wi-Fi
- Your home Wi-Fi network details
- Spare key to your deadbolt (safety must!)
Time to gather: 1 minute. Pro tip: Charge your phone fully and download the app (August Home, Schlage Home, or Yale Access) ahead.
Safety Tips Before You Start
Safety first keeps this fun and stress-free.
Lock yourself out? Avoid it by testing with your physical key handy. Work during daylight or with good lighting. If you're in a multi-unit building, inform neighbors about temporary door fiddling.
Renter perk: Everything reverses in minutes—no damage proof for security deposits.
Total prep time: 2 minutes. Ready? Let's dive in.
Step 1: Choose and Check Compatibility (1 Minute)
Not all deadbolts play nice, but most do. Start here to avoid frustration.
Measure your door: Standard thickness is 1.375–1.75 inches. Check your interior thumb turn (knob inside)—it should spin freely without resistance.
Compatible types:
- Single-cylinder deadbolts (key outside, thumb turn inside)
- Most Kwikset, Schlage, or Yale brands
- Avoid double-cylinder (key both sides) or smart deadbolts already
Grab your lock from Amazon or Best Buy—August works with 90% of setups. Test fit: The retrofit plate should cover your old thumb turn hole cleanly.
Common mistake: Skipping this. Measure twice, or return it hassle-free.
Why renter-friendly? No exterior changes—your door looks unchanged from outside.
Step 2: Unbox and Prepare (1 Minute)
Rip open the box excitement!
Inside: Interior smart lock assembly, mounting plate (wing plate), screws, batteries (usually 4 AA), quick-start guide, and sometimes adhesive pads.
Prep checklist:
- Insert batteries into the lock body (twist open compartment).
- Charge any included bridge (for Wi-Fi models) via USB.
- Peel any protective films.
- Download app and create account.
App bonus: iOS users love Siri shortcuts; Android gets Google Home integration.
Pitfall: Dead batteries mid-install? Test them with a multimeter or swap.
You're set—no drilling tools needed.
Step 3: Remove the Old Interior Lock Plate (2 Minutes)
Time to evict the old thumb turn.
Safety: Prop door open with a wedge. Have your key inserted outside for quick access.
Steps:
- Locate 2-4 screws on the interior thumb turn plate (face of door inside).
- Use Phillips screwdriver to loosen counterclockwise. Keep screws safe—they're reused sometimes.
- Gently pull off the plate. The thumb turn spindle (metal bar) stays in the door.
- Wiggle out the thumb turn mechanism if attached.
Result: Exposed hole where smart lock mounts. Dust off with a cloth.
Beginner tip: Screws tight? Apply steady pressure—don't strip. If stuck, WD-40 lightly (wipe excess).
Renter win: Exterior untouched. Reverse anytime.
Step 4: Mount the New Smart Lock (3 Minutes)
The magic: Retrofit magic without holes.
Align the wing plate (curved mount) over the hole, matching screw holes.
Detailed mount:
- Slide wing plate onto spindle (it hugs the door edge).
- Position smart lock body over wing plate—tabs snap in.
- Secure with provided screws (hand-tighten first, then firm).
- Attach any cover or escutcheon for sleek look.
August example: Wing plate grips existing deadbolt tailpiece—no adjustments.
Schlage/Yale: Similar, with auto-align wings.
Time saver: Most self-align. Tug gently to test stability.
Common error: Misaligned spindle? Rotate thumb turn outside to match.
Test spin: Interior should turn smoothly. You're halfway!
Step 5: Pair with the App (1 Minute)
Tech time—effortless Bluetooth magic.
Open app, select "Add Lock."
Pair process:
- Enable Bluetooth/location permissions.
- Press pairing button on lock (usually reset hole with pin).
- App scans—lock blinks/LEDs flash.
- Name your lock (e.g., "Front Door").
- Connect to Wi-Fi (2.4GHz preferred).
iOS: Works with HomeKit. Android: Alexa/Google seamless.
Pitfall: No pair? Restart Bluetooth, move closer (within 10 feet).
Pro: Auto-firmware updates keep it secure.
Step 6: Test Keyless Entry (1 Minute)
Proof it works!
In app: Unlock via tap. Hear motor whir? Thumb turn spins—success!
Tests to run:
- Auto-unlock (geofencing: detects your phone nearing).
- Manual unlock/lock.
- Physical key override.
- Battery status check (app shows %).
Walk outside, lock via app, unlock with key. Smooth? Golden.
Safety: Enable "Activity Log" for who/what/when tracking.
Renter-friendly: Logs prove no unauthorized access.
Step 7: Set Up App Features for Guests and Codes (1 Minute)
Elevate to pro level.
Guest magic:
- In app: "Share Access" > Generate PIN code or e-key.
- Set schedules (e.g., cleaner 10-11 AM Tuesday).
- Temporary access expires automatically.
- Revoke anytime.
Bonus: Voice control—"Alexa, lock door."
Why love it? No key handoffs. Family gets permanent codes.
Common setup: Quiet mode (no beeps) for apartments.
Total time: Under 10 minutes! High-five.

Beyond speed, no-drill shines for renters.
- Reversible: Unscrew, replace old plate—zero traces.
- No lease violations: Exterior identical.
- Affordable: $100-250 vs. $300+ full replacements.
