What's in the Box

The Yale Assure Lock SL with Z-Wave package includes the exterior touchscreen keypad assembly (with no physical key cylinder for a sleek, key-free look), the interior lock assembly with a Z-Wave module, a mounting plate, a latch bolt, strike plates, four AA batteries, installation hardware, and an installation guide. The "SL" stands for slim, referring to the streamlined exterior design without a traditional keyhole. The Z-Wave module requires a compatible Z-Wave smart home hub for remote access and smart home integration.

Prerequisites

Before you begin installing the Assure Lock SL, confirm the following:

Your door has a standard deadbolt preparation (2-1/8 inch face bore, 1-inch edge bore)
The door thickness is between 1-3/8 inches and 2-1/4 inches
You have a Z-Wave compatible smart home hub such as Samsung SmartThings, Hubitat, Ring Alarm, or a Z-Wave enabled home automation controller
The Yale Access app is installed on your smartphone (iOS or Android)
A Yale account is registered in the app
A Phillips-head screwdriver is available

Step-by-Step Installation

Remove your existing deadbolt. Unscrew the interior thumb turn assembly, remove the exterior assembly from the front, and slide out the latch bolt from the edge of the door.
Install the Yale latch bolt into the door edge with the "UP" marking facing upward. Secure it with the provided screws.
Install the strike plate on the door frame, ensuring the bolt extends smoothly into it when the door is closed. Use the reinforcement plate for added kick resistance.
Thread the cable from the exterior keypad through the door face hole and hold the exterior assembly flush against the door.
On the inside, position the mounting plate and align the screw holes. Connect the cable from the exterior to the interior assembly.
Mount the interior assembly, insert four AA batteries, and fasten the screws. Make sure the assembly is snug but not overtightened.
Test the lock manually using the interior thumb turn and by entering a code on the touchscreen keypad to confirm the bolt extends and retracts properly.

App Pairing and Z-Wave Hub Setup

Open the Yale Access app, tap "Set Up a New Device," and select the Assure Lock SL. The app connects via Bluetooth for initial configuration. Create a master code and add user codes for family members. To enable remote access and smart home features, you need to pair the lock with your Z-Wave hub. Put your hub into Z-Wave inclusion mode (the process varies by hub brand), then initiate pairing from the lock's settings menu. The lock will appear as a new Z-Wave device on your hub. Through the hub, you can lock and unlock remotely, receive lock and unlock notifications, and create automations.

Smart Home Integration Tips

With a Z-Wave hub, the Assure Lock SL integrates into broader smart home ecosystems. On SmartThings, the lock appears as a controllable device and can be included in Smart Home Monitor routines and automations. Create automations like automatically locking the door two minutes after it closes, or unlocking the door when you arrive home based on your phone's GPS location. On Hubitat, the lock works with Rule Machine for advanced automations. If your Z-Wave hub supports voice assistants, you can use Alexa or Google Assistant to lock the door through the hub. Note that the Assure Lock SL does not have WiFi or HomeKit support unless you add a separate Yale Connect WiFi Bridge accessory.

Quick Troubleshooting

If the lock does not pair with your Z-Wave hub, make sure the hub is within 10 feet of the lock during the inclusion process. Z-Wave has a shorter pairing range than its operating range. If the lock was previously paired with another hub, you need to exclude it first using the Z-Wave exclusion process before pairing with a new hub. If the touchscreen keypad does not light up, check that the batteries are seated correctly and have sufficient charge. If the bolt jams or grinds, verify door alignment and ensure the latch bolt is properly installed with the correct orientation.
