Abstract
A locating system and method for locating objects, such as keys, is disclosed. The locating system may include a transmitter for transmitting an encrypted code in the 900 MHz band. The transmitter may be powered by a battery. By transmitting in the 900 MHz band, the battery power consumed by the transmission may be relatively low and the encrypted code may travel a relatively long distance, such as 100 feet or more. The locating system may include a battery-powered locator device that is configured to detect, receive, and/or decode the encrypted code and determine whether the encrypted code is associated with the locator device or an attached object. After which, the locator device may provide an indication of its position. For instance, an audible sound of 85 dB or greater may be generated. The transmitter may be a self-contained device, or affixed onto or incorporated into a communications device.
