CODELOCKS CL255KO Series Digital Lock With Key Override

The Codelocks CL255KO is a premium, light-duty mechanical digital lock from the popular CL200 series. Designed with a dual backplate and a mortice latch, it features a highly convenient key override facility. This key override is particularly useful for cleaning, maintenance, and security staff, allowing immediate access by bypassing the code.

The spring-loaded latch locks automatically when the door is closed, and it is equipped with a deadlocking plunger to prevent unlawful shimming. For added flexibility, a slide button on the backplate can be used to hold open the latchbolt for free entry without entering a code. If required, this hold-open function can be disabled during installation to ensure a code is always required.

This digital lock is available in both fire-tested and non-fire-tested versions. Please choose your preferred option from the selection below. The fire-tested model is supplied complete with an optional fire holdback kit and is tested to BS EN 1634-1 standards. For the non-fire-tested model, an appropriate intumescent pack must be fitted to achieve a fire rating (please see associated products). Depending on the version selected, the weight ranges from 1.229kg to 1.28kg, and the manufacturer reference will vary. Please select your preferred options below.
