In an effort to combat violence and enhance the sense of security among women, the city of Metz has initiated the distribution of free keychains designed to emit a blinding light and a loud alarm.

The keychains aim to dissuade potential aggressors in public spaces.

Currently, 1,500 keychains are available, with an additional 4,000 expected to be distributed by early April 2025.

These devices resemble a car remote but serve a critical function in emergency situations.

Equipped with a LED light that flashes brightly, the keychain can activate a 140-decibel alarm—comparable to the sound of multiple firecrackers—when the user pulls a cord attached to it.

This feature is designed not only to attract attention but also to potentially scare off aggressors, with the mayor of Metz, François Grosdidier, claiming that the alarm should succeed in making aggressors flee in nine out of ten cases.

The initiative is part of a broader strategy to address both violence and the growing feelings of insecurity reported by women in public.

In addition to the keychain program, the city has allocated around 100 parking spaces specifically for women near public entrances and exits.

Furthermore, local restaurateurs and shopkeepers have the option to join the 'Angela' network.

This initiative allows individuals who feel threatened to seek refuge by asking for 'Angela' at participating establishments, providing a safe space in moments of distress.
