"NICB’s four layers of protection are:

Common Sense: Lock your car and take your keys...
Warning Device: Having and using a visible or audible warning device...
Immobilizing Device: Generally speaking, if your car won’t start, it won’t get stolen...
Tracking Device: A tracking device...

Passive security measures are best when coupled with more active modes of anti-theft protection...

Seriously tho, who DOES NOT lock their car and take their keys these days??
