Electronic key finders are tiny tracking devices that can be attached to a keyring or other frequently lost item. Safeguards built in to some tracking devices to notify a person when they are being tracked, are compromised because devices can be turned off once tracking is undertaken sufficiently, can be muffled or hidden out of view, or require an app to notify of illicit tracking, which is not usually in use by a victim.If you’re tired of misplacing your keys, there’s good news: technology can take this daily frustration off your plate. Tracking devices have been implicated in criminal activity, such as stalking and identifying when properties are empty.
Even though different manufacturers use the same underlying technology and standards, their apps do not share information with each other, so each manufacturer requires a different app for its devices.Įxample of trackers that work this way are Chipolo, ON!Track (by Hilti), AirTag by Apple, Tick (by Milwaukee Electric Tool Corporation), Tile, TrackTag (by Bosch), TrackR and PROTAG.

Modern key finders use a Bluetooth low energy beacon to broadcast a uniqueID that is picked up by nearby phones running the appropriate software, that is then reported to the manufacturer's website along with the location where they picked up the signal. Having a transmitter in each unit also means that, unlike second generation units, losing a single transmitter does not result in total loss of the ability to find other items it tracks. The seeking unit can then follow this beacon to find even a buried set of keys. In addition, since the keyfinders have their own transmitters, they can reply to each other by radio as well as by beeping and flashing a light to attract attention.

The user can, for example, use a digital wallet to find misplaced keys and vice versa, or a mobile phone to find a lost TV remote control or eyeglasses. Peer-to-peer key finders no longer require a separate "base" they are all functionally identical and based on a communication system wherein each device can find all the others individually. The transmitter can also contain information to help return it to its rightful owner. Some distributors include a cost-effective key-return service that assists in returning the keys should they be lost in a taxi, bus or other public place, provided the customer registered their devices and contact information. Using a radio signal removes the risk of false alarms. All wireless key finders have to "listen" for a searching transmission, resulting in battery replacement at intervals ranging from 3 months to a year. A separate transmitter is used to activate one or more receivers. Because of this low quality and unreliability, these early key finders were soon discarded and were unpopular for serious needs.Īs electronics became smaller and cheaper, and battery life improved, radio became viable to locate the keys, which were fitted with a small receiver. Determining what was a clap or a whistle proved difficult, resulting in poor performance and false alarms. Early models of key finder were sound-based, and listened for a clap or whistle (or a sequence of same), then beeped for the user to find them.
