Buying Guide: Key Considerations for Non-Drill Door Locks
- Door type and compatibility: interior vs exterior doors; knob, lever, or handle configurations; door thickness and handle diameter.

- Security level: whether the lock blocks the keyhole, prevents door opening from outside, or simply adds a physical barrier.
- Portability: travel size, weight, and ease of packing for trips or hotel stays.
- Durability and materials: metal vs plastic; impact resistance and long-term wear on doors and frames.
- Safety considerations: ensuring the device does not impede egress during emergencies and is used as a supplemental measure rather than a sole security solution.
