Key finder in test: The best key trackers

Hardly anything is more annoying than losing your keys. In the best case, you'll be late for work because of the subsequent search, in the worst case, the bunch of keys will be lying somewhere in the meadow - and you'll have to have all your keys made up. To avoid this horror scenario, our partner AllesBeste has tested key finders with finding apps, such as the Apple Airtags. Key finders usually don't cost much: good models start at around 15 euros each. But you can also pay more than 50 euros for the best ones.
