Catalytic converter theft: how to protect your car

By TOYOTA UK

Catalytic converter theft from cars isn’t a new crime, but it has increased significantly in recent times.

Police forces around the UK are advising owners of any car fitted with a catalytic converter to take precautions. In Toyota’s case it is second and third-generation Prius models (2004-2009 and 2009-2016 respectively) and second-generation Auris Hybrids (2012-2018) which have been particular targets for thieves.

Below we’ve gathered the best advice for Toyota owners who may be concerned.

What is a catalytic converter? 

The catalytic converter is part of the car’s emissions control system. It cleans up the exhaust gases before they are expelled from the car through the exhaust pipe. Its internal elements react with the gases, breaking them down into less harmful substances and water vapour. All new cars sold in Europe since 1993 have had to be fitted with a catalytic converter by law.

Why are they a target for thieves?

Clearly the police are best placed to offer advice on the motives behind this crime. But we understand that the value of the catalytic converter for recycling is the main attraction to thieves, because it contains precious metals such as rhodium, platinum and palladium.

What can owners do to stop their cars being targeted?

Some owners have chosen to tag their catalytic converters with an invisible yet traceable forensic marking solution, such as that provided by SmartWater. This means that a stolen catalytic converter can be traced to a specific crime, helping police in their attempts to fight the organised gangs responsible. It also raises the risk to all those handling the devices along the criminal chain, from theft to eventual disposal and recycling. Mechanical theft prevention products such as Catloc devices can also deter thieves.

However, it must be noted that catalytic converter theft is a criminal operation and the scope of owners is therefore limited. Police forces are taking action, so it is important for anyone who is a victim of this crime to report it as quickly as possible.

In the main, older cars are more likely to be targeted. This is because advances in efficiency and technology mean the latest generations of catalytic converters contain vastly lower amounts of precious metals, while still doing their job just as well or even better. This means their value for recycling is very low and they are not attractive to thieves.

Does a mechanical lock give my car 100% protection from thieves?

Sadly not. It can make theft more difficult but thieves are using high-powered cutting tools to remove catalytic converters and because of this it is not possible to make them ‘unstealable’. A mechanical locking device makes it harder to steal a catalytic converter because it slows down thieves and therefore acts as a deterrent.

  1. I have a 2021 RAV4 HEV – reg DF70 ***. I just had the CAN bus armoured plates installed after an aborted theft attempt using the CAN bus vulnerability approach (for the info of others with the same vulnerability, labour-only charge at local dealer (£70/hour – took one hour at my dealer). What is the risk for my car of catalytic converter theft (i.e. high enough for a Catloc?)?

    Please obscure the reg on publicly posting this query.

    Thanks

      Your RAV4 is deemed as a low risk for catlytic converter theft so there is no Catloc available. We do however, offer free of charge SmartWater marking for all of our Hybrid vehicles. Your local Toyota Centre can provide further information on this.
