Catalytic converter theft: how to protect your car

The theft of catalytic converters from cars isn’t a new crime, but it has increased significantly in 2019.

Police forces around the UK, including those in West Yorkshire, London and Nottinghamshire, are advising owners of any car fitted with a catalytic converter to take precautions.

Any car fitted with a catalytic converter could be at risk. 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. Located close to the engine, 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 cars sold in Europe since 1993 have had to be fitted with 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 in the main, the value of the catalytic converter for recycling is the main attraction to thieves, because they contain precious metals such as rhodium, platinum and palladium.

What is Toyota doing to stop its cars being targeted?

We’re doing all we can. We’ve shared police guidance with customers, and we have developed and reduced the price of a ‘Catloc’ device which can deter theft and make it more difficult. We are urgently exploring new technical possibilities to deter criminals as well.

However, these are criminal operations and our scope is therefore limited. A number of police forces are taking action and some forces, such as Nottinghamshire, are also starting awareness campaigns. It is vitally important for anyone who is a victim of this crime to report it to their local police force as quickly as possible.

How much does the Catloc cost?

The Catloc costs between £200 and £250 (depending on model), which includes VAT and fitting by a Toyota retailer. It comes with three-year warranty.

Does a Catloc 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 catalytic converters ‘unstealable’. As mentioned above, we’re doing all we can to seek further technical options for customers.

Is Catloc available for my Toyota?

Catloc devices are available for a proportion of our range, but not all. We recommend speaking to your local Toyota centre.

How much does it cost to replace a catalytic converter?

Toyota’s first priority is to do all we can to support our customers who have been victims of crime.

We have moved to reduce the prices of replacement catalytic converters and Catlocs to a level where Toyota GB does not make any profit from supplying them to customers.

Our recommended prices for a bundle that includes a new catalyst and a Catloc are £950 for Auris Hybrid, £1,000 for Prius Gen 2 and £1050 for Prius Gen 3.

Your nearest Toyota centre can advise on exact costs after inspecting your vehicle.

Is it true that there is a long wait for replacement catalytic converter parts for Toyota cars?

The rapid rise in this crime in 2019 is one we could not have envisaged, set against many years of low incidence of catalytic converter theft. This has impacted our ability to source enough of the parts we need in some cases, for which we sincerely apologise.

We have taken urgent action with our suppliers to try to resolve this. For example, our supplier of Auris catalysts has now increased daily production shifts from one to three, which we hope will allow us to tackle this issue and get customers’ cars back on the road more quickly.

  2. Dear Toyota,

    I had my Catalytic Converter stolen in July, when i placed my order for a new one for my Auris 2018 I was informed it should arrive in 2 weeks as we were ordering through my mechanic. However, my mechanic called after 2 weeks to get an update on where the catalytic converter is, but were then told we were placed on back order which is very frustrating. I work with a hospital and require my car as my every day job, due to this issue i haven’t been able to carry out my job requirement.
    Catalytic converter thefts has been a long term ongoing issue with Toyota cars, it only makes sense to make changes to your cars or create something free of charge to prevent any of these issues. However, from what Toyota customers see is that you continue making the same designs causing havoc with to customer, and then leaving them without cars due to failing to produce enough catalytic converters to cover this ongoing issue.

    I would like to know when i will be able to get hold of my catalytic converter that has been paid for delivered as my car is needed for my NHS based job.
