Step-by-Step Guide to Install a Retrofit Smart Lock
Example Product: August Wi-Fi Smart Lock (4th Gen). Compatible With: Existing single cylinder deadbolts without drilling requirements.
Step 1: Remove interior thumbturn
Unscrew the thumbturn plate from within your door. Make sure the outer keyed cylinder remains undamaged; this ensures rental-safe operation of your setup.
Step Two: Align Mounting Plate
Attach the included plate using existing screws, making sure that the tailpiece aligns directly through the adapter slot.
Step 3: Attach Smart Lock Body
Clip or slide the lock body over the plate; most units (including August and Wyze Lock models ) snap into place automatically. Tighten clamps by hand – no drilling necessary!
Step 4: Connect via App
To connect using Bluetooth/Wi-Fi, download and create an account within the manufacturer app before connecting via Bluetooth/Wi-Fi to name your device (“Front Door,” “Back Door,” etc).
Step 5: Verify Lock & Reversibility Capabilities
Use both your phone and the original key for optimal operation, and test its reversibility by uninstalling and reinstalling once.
