Abstract
A locating system for locating objects, such as, but not limited to, keys is disclosed. The locating system may include a mobile communication device having at least one audible tone generator in communication with a control module, wherein the control module is configured to send a signal to the audible tone generator to emit an audible tone. The locating system may also include a locator device physically detached from the mobile communication device. The locator device may include a receiver configured to receive the audible signal from the audible tone generator and to generate a signal. In alternative configurations, the locating system may send an audible sound that is incapable of being heard by an unaided human ear. In another configuration, the locating system may send a sequence of audible tones to activate the audible tone generator, thereby enabling a set of keys on a key ring to be located.
