An object locator system includes a transmitter unit which sends one of a plurality of RF signals upon actuating a first pushbutton, and a receiver unit attached to or incorporated into an object for detecting the RF signals and illuminating a light element and/or activating a sound speaker in response to the detected RF signal. The user may program the receiver unit by using the transmitter unit to select a specific melody or song stored in the receiver unit. The transmitter unit may be used at one time with a plurality of receiver units by programming the transmitter unit to send a unique coded signal corresponding to each receiver unit. The object locator system may also be set in a protection mode which continuously transmits an RF signal but activates the light element and/or the sound speaker only when the receiver unit no longer detects the RF signal.
