Losing your keys is not fun. Unfortunately, many of us come to experience that the hard way. Technology is your best friend here. There are plenty of cheap Bluetooth trackers you can take advantage of to track your keys. The Swisskey happens to be a nifty key organizer that syncs to your phone and helps you find lost keys fast.
Users can create a virtual leash for their Swisskey to get alerts when they are too far away from their keys. Once you get in-range again, your phone alerts you, so you can find your keys faster. Swisskey is compatible with iOS devices with Bluetooth 4.0. It works with Android devices too. The battery lasts for over a year, which is not bad at all.
Swisskey can be personalized or self-assembled. You can add or remove tools easily. Yet another interesting key finder.[where to get it]
