Two into one – a car key and alcohol tester

Categories: Locks, Keys

Japanese companies Honda and Hitachi developed a car key that can function as a alcohol tester.

The device is the size and shape of a small smartphone and takes into account alcohol levels within three seconds after the driver drives the car. Developers say the device is able to distinguish human breath from other gases.

The key can be used with the system developed by the two companies, which shows the alcohol levels recorded on the car dashboard display and prevents the engine from being lit if the driver overcame the cups.

The advantage of prototype development in front of other similar systems is that it can be used before the driver is sitting behind the wheel and being tempted to drive the car intoxicated.
