A biometric safety and security system ( 10 ) that is designed to prevent a person that is inebriated or that is not assigned the use of a particular vehicle ignition key ( 170 ) from starting the vehicle. The system ( 10 ) utilizes an enclosure ( 50 ) that houses an electronics circuit ( 12 ) that includes a microcontroller ( 14 ), a fingerprint scanner ( 26 ), a speech verifier ( 28 ), a breath analyzer ( 29 ) and the ignition key ( 170 ) which is normally retracted into the enclosure ( 50 ). To extract the key ( 170 ) a person must verify their identity by means of the fingerprint scanner ( 26 ) and/or the speech verifier ( 28 ), and also verify their sobriety by means of the breath analyzer ( 29 ). If the person's identity and sobriety are verified a signal is sent to the microcontroller ( 14 ) where a signal is produced that activates a motor interface ( 32 ), that operates a d-c motor ( 34 ) that extracts the key from the enclosure ( 50 ).
