I really don't like biometric authentication. As has been said before it's kind of like using your username as your password. Simple ownership is presumed to be enough data to prove you belong. Additionally I (personally) think it's a problem that the authentication method can't be changed. You can have new keys cut, you can change your password, but it's unlikely you'll ever get new handprints. For me there's also the factor that it places the access holders at additional physical risk. I read an article a while ago about a guy that had a car with a fingerprint scanner installed... Carjackers wanted his expensive car, so they cut off his finger, stole his car and left him. Personally I would rather someone just took my keys.
