Buying Guide
Key considerations when selecting a secure lock box for keys:
- Capacity: Choose based on how many keys or items you need to store. If you only need a couple of keys, a smaller model may be sufficient; for real estate or property management, a five-key capacity is common.
- Material and durability: Metal bodies and weatherproof seals help endure outdoor environments. Look for rust resistance and a protective shutter design for dials.
- Security features: A resettable four-digit code provides flexibility. Ensure the code remains private and choose models with tamper-evident features if available.
- Mounting options: Wall mounting offers permanence; portable or knob-hanging options add flexibility for multiple locations.
- Installation effort: Some boxes include screws and expansion plugs; others offer simple door-knob hanging. Select based on the installation surface and security needs.
