CATGUARD (Catalytic Converter Theft Prevention) Pilot Program

3 photos of the CATGUARD system

Minnesota has one of the highest theft rates of catalytic converters in the nation. Criminals who steal catalytic converters can cut them off with a saw in less than a minute and sell them. The value of the precious metals in catalytic converters can make them worth up to $1,600.

Catalytic converters often do not have serial numbers and those that do are generally not traceable to the vehicle they were installed on. The lack of identification numbers on catalytic converters makes it extremely unlikely an officer or deputy will be able to link a detached catalytic converter to a crime.

The Ramsey County Sheriff’s Office has partnered with the Minnesota Department of Commerce Fraud Bureau in a pilot program to promote catalytic converter theft prevention by distributing self-install marking kits to residents of Ramsey County who have a high-risk for theft vehicle, or have had a catalytic converter stolen.

The marking kits include:

  • a label to be installed on a "cool to the touch" catalytic converter and painted with a metal marking fluid that causes a unique number to be etched into the catalytic converter.
  • two warning labels that indicate your vehicle has a marked catalytic converter.
  • information on "how to register the label's unique code number" and "information updates" which allows law enforcement to trace the marked converter back to a specific vehicle if the converter is stolen and later recovered.

The kits are limited to specific vehicles (see list below) and supplies are limited.

Victims of catalytic converter theft from a vehicle not on this list are eligible by providing a police report number.

To receive a marking kit:

Go to the Ramsey County Sheriff's Patrol Station

  • 1411 Paul Kirkwold Drive, Arden Hills MN 55112
  • Open: 8:00 am - 4:00 pm Monday-Friday (closed Holidays)
  • You will need: vehicle identification number (VIN) and license plate number

​The law requires labels be installed at no cost to vehicle owners. Businesses cannot charge for the installation of a label, but they can require another service, such as an oil change, be performed at the time of installing the label.

If your vehicle is not on the at-risk list, an alternative is to engrave your catalytic converter(s) with the VIN or partial VIN (the last 8) of your vehicle. It is recommended to apply a bright colored high-temperature paint with the engraving.

If your marked catalytic converter is stolen please report the theft and provide the marking details as soon as possible.
