Catalytic converter theft: how to protect your car

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

Police forces around the UK, including those in West Yorkshire, London and Suffolk, 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. 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?

In May 2021, Toyota (GB) announced that it would be covertly marking more than 100,000 catalytic converters in order to combat theft. By working with police and Smartwater, catalytic converters can be tagged with an invisible yet traceable marking, meaning 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.

It is free to get the catalytic converter marked, all customers need to do is call their local Toyota or Lexus retailer to arrange a visit.

In addition to this, Toyota has issued 20,000 Smartwater kits to police to support their local anti-catalyst theft initiatives. The company is also working with the AA, Toyota’s roadside partner, so its patrols can point customers to where they can get a free kit.

We have also developed and reduced the price of a ‘Catloc’ device which can deter theft and make it more difficult. Toyota teams in the UK and other countries are urgently exploring new technical possibilities to deter criminals as well.

We are working with the police, as well as talking to government about changes in the law around scrap metal sales that would make it harder for criminals to sell stolen catalysts for cash.

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.

In the main, it remains older cars that are targeted because advances in efficiency and technology mean the latest generations of Toyota catalytic converters contain vastly lower amounts of precious metals, whilst 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 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’. A Catloc makes it harder to steal a catalytic converter, slowing thieves down and acting as a deterrent. 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 growing 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.

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 initially impacted our ability to source enough of the parts we needed in some cases, for which we sincerely apologise.

Toyota has restarted production lines in Japan and France that made catalysts for many of the older models targeted in order to supply affected owners, developed a Catloc security device which helps deter theft (and has been granted a “Sold Secure with Gold Status” security ranking) and ensured it makes no profit at all from the sale of replacement catalysts or from Catlocs, providing them at cost.

  1. Is the C-HR vulnerable to catalytic converter theft and if so, what is available as a deterrent for this model? Thanks

    1. Hello Steve, thanks for your comment.

      The C-HR is currently predicted as a low-risk model. However, we would recommend getting in touch with your local Toyota Centre as they will be able to forensically mark the catalytic converter with SmartWater which is helping to deter theives. They will also be able to check if your vehicle can be fitted with a Catloc.

      Thanks.

    1. Hi,

      Technically all vehicles fitted with a catalytic converter are at risk of theft. We do supply a Catloc for the 1.8 hybrid Corolla, as well as Smartwater kits and bolt welding. Unfortunately a tilt alarm is not currently available for this vehicle.

      Thanks

  2. Is toyota RAV4 hybrid 2020 model vulnerable to catalytic converter theft? if so is catloc available for this model?

    Thanks.

    1. Hi Jo,

      Technically, any vehicle fitted with a catalytic converter is at risk of theft. Organised criminal gangs tend to be targeting older hybrid vehicles. It is considered low risk at the moment, therefore a Catloc is not currently available. However, you can have the catalytic converter marked with Smartwater. We are constantly re-evaluating our position and if necessary, we’ll develop and introduce a Catloc for that vehicle.

      Thanks

  3. Hi I am buying a Hybrid corolla in July 2021, I spoke to the Toyota dealership and they couldnt put my mind at rest on how this model is protected into relation theft of catalyst converters… or even what measures are in place, I also asked about smart water and they said they do not do this for new models… Can someone advise me i dont know if i should just withdraw from buying?

    1. Hi Ro,

      Thanks for your interest in the Corolla. Technically, any vehicle fitted with a catalytic converter is at risk of theft. Organised criminal gangs do tend to target older hybrids though. Whilst the new Corolla is currently considered low risk, we have developed a Catloc for the 1.8 litre hybrid Corolla. Smartwater marking kits can be applied to any vehicle.

      Thanks

  4. I have an old 2007 Auris Diesel. How high a risk are diesel models, and what’s the best way of protecting it?

  5. Hi, looking at purchasing new CHR 1.8 model, is the car at high risk of having a catalyst convertor stolen?

    1. Hi Ash,

      Thanks for your interest in the C-HR. Technically, any vehicle fitted with a catalytic converter is at risk, but older hybrids tend to be the main target for thieves. C-HR is considered low risk, but a Catloc is available on the 1.8 hybrid model for peace of mind.

      Thanks

    1. Hi,

      2013 Yaris Hybrid is considered low risk. There is currently not a Catloc available for your vehicle.

      Thanks

  6. i have a Toyota Prius+ Estate 1.8 VVTi Excel TSS 5dr CVT Auto . Is my car classed as high risk of having cat stolen and how much is catloc for my model

    1. Hi Michael, thanks for your comment.

      Your Prius would be classed as high risk and a Catloc is available at a cost of approximately £250. Your local Toyota Centre will be able to confirm this cost.

      Thanks.

  7. Why are Toyota emblazoning their vehicles with HYBRID as this surly says come and steal my converter !
    And marking a converter doesn’t deter anybody as it’s under the car and when it’s nicked thieves no who to sell to!
    The logical deterrent is to make a converter that doesn’t have all these precious metals in them, and that isn’t beyond expectations in this day and age!
    And then to have Toyota replace the converters free of charge to drivers of their vehicles! WOW! What a customer relation coup that would be!
    George.

    1. Hi George, thanks for your comment.

      Newer vehicles do have a much lesser percentage of precious metals in the catalytic converter. As for prices, we carry out all replacements and the fitting of catalytic converters at cost price and do not make a profit from this work.

      Thanks.
