This is the second installment of the "Keylex Case Studies Introduction: Store Edition." Keylex is being adopted and implemented in stores and commercial facilities. I believe that restaurants and similar establishments that employ many part-time or temporary workers often struggle with key management. With Keylex, doors can be opened with a button press, eliminating the need to prepare keys for each employee and preventing issues related to lost keys or retrieving keys from departing employees! With the automatic locking type, the door locks automatically when closed, preventing any forgetfulness in locking up after closing. If the store is not open 24 hours, it is also possible to restrict access at night to prevent unauthorized entry by those who know the passcode.

The Keylex 4000 series has a setting with an "Emergency Opening Device." The "Emergency Opening Device" allows the door to be opened by pulling up the green cover at the bottom of the Keylex body and sliding the release lever in case of an emergency. This mechanism enables unlocking without having to enter a PIN or use a key. Even after breaking the cover to operate it, you can reuse it by simply purchasing a new cover component! In terms of usage cases, both outdoor and indoor applications often feature a dual-button type with the emergency opening device installed on one side. Normally, it operates with a PIN, allowing access in emergencies to exit externally or, conversely, to enter internally. Therefore, it is implemented in evacuation routes and emergency exits in facilities such as nursing homes, schools, hotels, and train stations. It can also be installed in areas where fire department guidance is required! For the dual-button type, it is compatible with keyed options and other manufacturers' cylinders (MIWA/GOAL/HORI cylinders). This feature contributes to reducing damage during disasters! *Please note that the door can be opened from the emergency opening device without entering a PIN, so handle it with care.
