Setup and Installation
The WINONLY Portable Door Lock requires no tools or permanent installation. Follow these steps to secure your door:
- Step 1: Insert the Claw
Open the door slightly. Locate the strike plate on the door frame where the door's bolt extends. Insert the metal claw of the portable lock into the strike plate hole. Ensure the claw is fully seated and stable.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lock does not fit into the door frame's strike plate. | The door bolt or strike plate opening is too large or too small for the lock's claw. | The lock features both small and large holes to accommodate most door types. Ensure you are using the correct hole for your door's bolt. This lock is designed for standard inward-opening doors. It may not be compatible with all door designs or non-standard strike plates. ![]() Figure 5: The lock features both smaller and bigger holes to fit standard and larger bolts. Test before use. |
| Red handle does not jam securely. | The metal plate is not fully seated in the strike plate, or the door is not completely closed. | Ensure the metal claw is fully inserted into the strike plate and the door is completely closed and latched before attempting to push down the red handle. Apply firm, downward pressure. |
| Lock feels loose or unstable after installation. | Improper installation or incompatibility with door type. | Review the "Setup and Installation" steps carefully. Confirm that your door opens inwards. If the issue persists, the lock may not be suitable for your specific door frame or bolt configuration. |
