Twp. of Washington NJ, according to Twp of Washington Police there is an overall rise in catalytic converter thefts around New Jersey. The Ridgewood blog has frequently reported how widespread this crime is in Bergen County . Catalytic converters are sought after because they are sold to scrap yards for several hundred dollars per piece, for the valuable metals (platinum, rhodium, and palladium) inside of them.
You can make your car a less likely target by:
Park in well-lit areas
When at home, parking in the garage, with the door closed if you are able too
Having the converter welded to your car frame.
If you have a security system on your car, calibrating it so vibration sets it off. This ensures the alarm activates if a thief tries to saw off the converter.
Engraving your (full) VIN number onto your catalytic converter (to make it easier to identify, if stolen).
