A four-digit code cam lock with a green/red indicator and management key is an advanced locking solution, ideal for applications where a blend of user convenience, security, and administrative control is required. This lock is commonly used in settings like gyms, schools, offices, and public lockers where users need quick, keyless access, and facility managers benefit from override capabilities.

Key Features to Look For:

1. Four-Digit Combination Code:

   • 10,000 Possible Combinations: Provides enhanced security compared to three-digit options, making it suitable for moderately high-security applications.
   • User-Settable Code: Users can set and reset their four-digit code, allowing easy changes for rotating users or shared lockers.
   • Smooth Dials for Quick Code Entry: The four dials are typically easy to turn and durable, allowing quick entry without a key.

2. Green/Red Status Indicator:

   • Visual Open/Close Indicator: The green and red indicator shows at a glance whether the lock is in an open or locked state, which helps prevent user error and provides extra security assurance.
   • User-Friendly Design: Especially useful in shared environments, as it provides a quick visual cue for both users and management staff.
   • Enhanced Security: The indicator ensures that lockers or cabinets aren’t accidentally left open, reducing the risk of unauthorized access.

3. Management Key for Override Access:

   • Master Key Access: Allows facility managers or authorized personnel to open the lock without the user code, ideal for emergencies or maintenance access.
   • Code Reset Capability: In some models, the management key can reset the code, enabling secure reuse for new users.
   • Increased Control: Provides administrators with a way to access locked compartments without needing to force the lock, preventing damage to lockers or cabinets.

4. Knob Handle for Easy Operation:

   • Turn Knob Design: After entering the correct code, users turn the knob to open or close the lock, which is ergonomic and reduces the need for additional tools.
   • Comfortable Grip and Operation: Designed for frequent use, the knob handle makes it easy to lock and unlock without hassle.

5. Durable Construction:

   • Stainless Steel or Zinc Alloy Housing: Built for robustness, these locks are resistant to tampering and wear, making them suitable for high-traffic environments.
   • Corrosion-Resistant Finish: Ideal for humid areas like gym locker rooms or outdoor storage, ensuring long-lasting durability.
   • Compatible with Different Materials: Usually fits standard metal, plastic, and wood doors, allowing versatility in applications.

6. Installation and Compatibility:

   • Standard Cam Mechanism: Fits most standard cam lock cutouts, making it easy to install or retrofit into existing lockers, cabinets, and drawers.
   • Adjustable Cam Lengths: Offers different cam options (e.g., straight or offset) to fit various door thicknesses and closure preferences.
   • Easy Installation: Simple installation process with basic tools, making it adaptable for new installations or replacements.

Common Applications:

• Fitness and Gym Lockers: Provides secure, keyless access and easy management, reducing the risk of lost keys and allowing users to set their own codes.
• Schools and Universities: Useful in student lockers and staff cabinets where frequent access and code changes are needed.
• Office Storage Solutions: Ideal for securing office cabinets and drawers where administrative access is required, as in shared spaces or sensitive file storage.
• Public and Shared Lockers: Widely used in public spaces like libraries, co-working spaces, and transportation hubs where management may need to override locks for security or maintenance purposes.
