Learn how to replace the Wyze Lock Bolt battery cover, deadbolt, strike plate, and latch. Step-by-step instructions with common mistakes to avoid.
Quick answer
To replace the Wyze Lock Bolt battery cover or the deadbolt, strike plate, and latch, you'll need the correct replacement parts and a Phillips-head screwdriver. Follow the steps below to swap them safely without damaging the lock.
Why replacement parts matter
The Wyze Lock Bolt's battery cover protects the batteries and interior assembly from dust and moisture. If it's cracked or missing, the batteries can shift, causing intermittent power issues or even lock failure.
The deadbolt, strike plate, and latch work together to secure your door. Over time, these metal parts can wear down, especially if the door is misaligned or frequently slammed. Replacing them as a set ensures consistent performance and avoids mismatched parts.
Choosing the right part
The Wyze Lock Bolt battery cover and the deadbolt, strike plate, and latch are sold separately. Check your lock's model (WLCKB1) to confirm compatibility. If you're unsure, contact Wyze support with your lock's SKU.
For the battery cover, verify that it's the interior assembly cover (SKU WLCKB1-BC1). For the deadbolt set, confirm it includes all three components—deadbolt, strike plate, and latch—as one unit (SKU WLCKB1-DL1).
Step-by-step replacement process
- Gather tools and parts: You'll need a Phillips-head screwdriver and the correct replacement part (battery cover or deadbolt set). Turn off the lock's power via the app and remove the interior assembly from the door. Always disconnect power before handling the lock to avoid electrical issues.
- Remove the old battery cover: Locate the battery cover on the interior assembly. Press the release tab (if present) or gently pry it off with a flathead screwdriver. Do not force it—if it doesn't come off easily, check for hidden screws. Forcing the cover can crack the plastic; use a plastic pry tool to avoid damage.
- Install the new battery cover: Align the new battery cover with the interior assembly and press it into place until it clicks. Ensure it sits flush and there are no gaps. Reinsert batteries if you removed them. A loose cover can allow moisture in; press firmly until it clicks securely.
- Replace the deadbolt, strike plate, and latch: Remove the two screws holding the latch on the door edge, then slide it out. Remove the deadbolt from the door face and the strike plate from the door frame. Install the new latch, deadbolt, and strike plate in reverse order, tightening screws snugly but not over-tightening. Check that the deadbolt extends and retracts smoothly before reattaching the interior assembly.
- Reassemble and test: Reattach the interior assembly to the door, ensuring the screws are aligned. Restore power and test the lock manually and through the app. If the lock binds, adjust the strike plate position slightly. Test multiple times with the door open and closed to ensure proper alignment.
