Mechanical Combination Cylinder Lock Atlo ATLO-KRM-823, keyless coded entry

Atlo ATLO-KRM-823 is a mechanical combination cylinder lock that provides keyless coded entry for doors and cabinets that accept cylinder fittings. The unit integrates a numeric code mechanism with a conventional cylinder-style lock body, enabling secure mechanical access control without batteries or electronic components. The design is suitable for environments where key management is impractical or where a power-free solution is preferred.

Advantages

The mechanical construction of the Atlo ATLO-KRM-823 offers reliable operation without electrical supply, eliminating battery replacement and electronic failures. The numeric code mechanism allows for simple code changes and reduces the need to distribute physical keys. Cylinder compatibility enables straightforward replacement of existing keyed cylinders while maintaining a familiar form factor for installation. Durable materials and a compact profile support long-term use in everyday access points.

Suitable for

• Interior and exterior doors with compatible cylinder fittings
• Office and storage cabinets requiring controlled access
• Small commercial premises where keyless entry is preferred
• Renovations replacing keyed cylinders with mechanical coded access

Key specifications

• Type: Mechanical combination cylinder lock with numeric code mechanism
• Operation: Keyless entry via user-set numeric code
• Compatibility: Fits standard cylinder-compatible door and cabinet fittings
• Power: Fully mechanical; no batteries or electrical supply required
• Form factor: Cylinder-style locking unit suitable for retrofit

How to use

Install the lock into a cylinder-compatible door or cabinet fitting following standard cylinder replacement procedures. Set the user code according to the included instructions by aligning the numeric elements and locking the code-setting mechanism. To operate, enter the numeric code and turn the cylinder to retract or extend the bolt as with a conventional cylinder lock. To change the code, follow the manufacturer’s code-reset procedure; the process is mechanical and does not require tools beyond those used for installation.

Usage recommendations

For reliable performance, ensure the cylinder dimensions match the door or cabinet cutout before installation and periodically verify moving parts are free of debris. Choose a numeric code that balances memorability and security, and restrict knowledge of the code to authorized users only.
