Ukey

Ukey solves all of these issues.
It does away with keys all together, and assigns a unique 4 digit pin number to each operator you have.
It is also programmable, so you can change, read, and see the last 10 operators that used your machine.
It also has extensive starter protection, hotwire detection of starter and ignition systems, and tamper alert, letting you know someone has attempted to use your equipment.
