No One Will Know

A touch instead of a blow, and indicator lights instead of BAC numbers. We’ve designed Ethylokey to be as discreet as possible. Because not everyone needs to know that you’re checking your alcohol level.

Better yet: it fits inside your pocket, on your keychain, and in the palm of your hand.

Effortless Charging

No cables, no hassle. EthyloKey recharges wirelessly via induction—just drop it on the pad and power up, even in your car. One full charge gives you days of alcohol detection, anytime you need it.

Future Ready

By 2026, the EU will require all new M- and N-category vehicles are pre-equipped with an Alcohol-Interlock Installation Facilitation (AIIF). Similar legislation is under review in the U.S. under the Infrastructure Investment and Jobs Act.
