SafeKey is a key that rapidly checks
a driver’s reaction time.

It's well-known that many drugs, including alcohol, significantly increase the time a person requires to react to a change in circumstance such as a red light or obstruction in the road. The SafeKey is a unique ignition key immobilizer that prevents a vehicle engine from starting if the driver is unfit to drive safely. It is fully independent of other driver analysis methods – breath or otherwise. It analyzes the only thing that counts: how quickly a driver can react to a stimulus – braking, swerving, and the like.
