The kh-security key alarm is a protective alarm that can be attached to your keychain or belt, bags, etc., using its metal keyring. When the metal pin attached to the keyring is pulled out of the device, a very loud continuous alarm sounds. The alarm will only stop when the metal pin is reinserted into the key alarm. While the alarm is activated, the integrated high-performance LED also flashes. Always carry the key alarm on your keychain, and you will have a companion that provides protection against robbery, harassment, and assault. Attackers will be deterred, and passersby will be alerted. With the included lanyard, the kh-security key alarm can also be worn around the neck, making it especially suitable for children and seniors.
