ML55
Digital lock
The ASSA ABLOY ML55 is a battery-powered digital locker lock designed for both shared-use and dedicated-use locker environments. Supporting shared and fixed user functionality, it is commonly specified across workplace, education, end-of-trip and public-use locker environments requiring flexible locker allocation and straightforward day-to-day administration. Override code functionality supports facilities management and emergency access requirements, while the low-power system is designed for reliable operation with typical battery replacement intervals of approximately 1–2 years depending on usage conditions.
