Abstract: A key charm has a timer and a device for alerting a user. The timer is set to wake up after a period of time such as five-six hours; at which time the device for alerting the user is energized for a short period of time such as thirty seconds. The device for alerting the user is, for example, a vibrator, a sounder and/or a light. The key charm can be provided to an individual so that when it alerts the individual, the individual will think of someone or will think of an advertisement. Optionally, a mute button is provided to mute one or more of the vibrator, sounder and light.
