When renovation is required, many multi-family housing organisations also take the opportunity to upgrade door security. Managing multiple units and regular tenancy changes with mechanical lock-and-key technology is time-consuming and inefficient. It can also create security vulnerabilities when keys are lost.
An easier, electronic solution without wires or batteries will save management time and money. This was the challenge faced at Metsäpurontie 20, a housing cooperative in Maunula, Helsinki. The doors at Metsäpurontie 20 had long been secured by mechanical locks and keys.
