Mechanical Combination Lock Atlo ATLO-KRM-93 — keypad-operated cylinder lock

The Mechanical Combination Lock Atlo ATLO-KRM-93 is a keypad-operated cylinder lock designed for keyless access control. This purely mechanical code lock enables opening by entering a numeric combination on the external keypad and operates without electricity, batteries or electronic components. The compact cylinder form factor fits a range of doors, cabinets and gates and provides a durable solution where frequent, low-maintenance access control is required.

Advantages

The lock offers reliable mechanical operation that does not depend on power or wiring, reducing points of failure and ongoing maintenance. Its keypad entry removes the need for keys, simplifying access management and eliminating lost-key issues. The robust cylinder construction and mechanical latching mechanism deliver long service life and consistent performance under regular use. Installation and code changes are handled mechanically, allowing rapid adaptation to different users or security needs without electronic programming.

Suitable for

• Office and internal doors where keyless entry is preferred
• Storage cabinets and lockers requiring controlled access
• Utility rooms, workshops and service areas with frequent user turnover
• Gates and external doors where a battery-free solution is needed

Key specifications

• Mechanical keypad-operated cylinder design for numeric code entry
• Keyless access—no keys required for unlocking
• No electronics or batteries—fully mechanical operation
• Suitable for installation in doors, cabinets and gates with compatible cylinder housings
• Durable construction for frequent use and low maintenance

How to use

To unlock, enter the preset numeric combination on the external keypad and operate the handle or turn the cylinder as required by the door hardware. To lock, close the door or cabinet and rotate the cylinder to the secure position according to the fitting. Changing the access code is performed mechanically following the manufacturer’s procedure; this typically involves removing or accessing the cylinder core and repositioning internal tumblers or pins to register a new combination. Installation requires fitting into a compatible cylinder cutout and securing with the appropriate fixing screw and internal components.

Usage recommendations

Use in environments where a battery-free, low-maintenance mechanical solution is preferred. Verify the cylinder dimensions and door hardware compatibility before installation. Periodically check mechanical parts for wear and lubricate with a light graphite or dry lubricant as recommended for mechanical locks; avoid liquid oils that attract dust. Change the numeric code when access needs to be restricted or after personnel changes.
