It uses neither Bluetooth nor radiofrequency. When the receiver hears the chirp, it chirps in response. This is the least common type of key locator-all parts of the device act as both a transmitter and receiver. The receiver responds by sounding an alarm or lighting up. The tracking gadget emits a radio signal, which locates your lost item. Instead, they come with a dedicated tracking device that is very easy to set up. RF trackers that use radio signals do not require the use of an app or a smartphone.

The sticker has to be paired with a locating device to work. They are perfect as they don’t make any sound and are tiny and passive devices. These work similar to the Bluetooth trackers and use small tiles or stickers to tag on your items instead of standalone receivers. They have a wide range but do not work effectively when physical obstructions are in play or when you have switched off the location services on your phone. You can also use the sensor on your keys to ping and find your smartphone. They use the location service or GPS on your phone to tell you your keys’ current location. The apps include advanced features like out-of-range notifications and map locations. Trackers with a dedicated remote often have a wider range but will have to keep track of another gadget.īluetooth trackers need to be connected to your smartphone and are controlled by using an app. While some key finders use a dedicated locating device, others rely on your smartphone. Newer versions of key locators use radio frequency data identification (RFID) technology or, in other words, local electromagnetic fields to mark locations. The locating device is used to send out a signal that “finds” the receiver using either Bluetooth technology or radio frequency transmissions. Key finders come with a device that you attach to your keys, known as a receiver and a remote or locating device.
