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 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. My catalytic converter theft this evening 22nd December at 4 pm, I think it’s so easy to stolen because I was in a shopping centre just for 30 minutes, I don’t know who is responsible for the poor protection of this car.my car is toyota auris 2013.

    1. Hi Vahid, thanks for reaching out to us.

      We are very sorry to hear that your vehicle has been targeted by thieves.

      Technically, any car fitted with a catalytic converter is at risk of theft, but organised criminal gangs have been targeting some of our older hybrid models due to the higher amount of precious metals within the catalytic converter.

      These materials were fitted to make the catalytic converter more efficient at removing harmful emissions, making the car cleaner. There was no way we could have envisaged the value of these materials rising so high in the last few years.

      As our hybrid systems have become more efficient, our newer models have up to 84% reduced precious metal content in the catalytic converter, making them less attractive to thieves. This is a criminal issue, and we working with various agencies, including the Police, to try to put a stop to it.

      Please contact your Toyota Centre to see what protective measures are available for your vehicle. If you would like to discuss this further, we recommend contacting our Customer Relations Team here: https://www.toyota.co.uk/help-centre#/iframe/https%3A%2F%2Fforms.toyota.co.uk%2Fcontact-us.

      Once again, we are very sorry that this has happened to you and hope you are back on the road soon.

      Many thanks.

  2. The catalytic converter of my RAV4 plug in hybrid was stolen the 21st of December in a car park. It took them just one minute (CCTV images show this). Police report done but police say they can’t identify the thieves. My car was towed to nearest Toyota garage (130£) that quoted 1400£ for replacement (!!!) and cannot commit on date as the part is on back order for…. 13th of January !!! They don’t think a cat lock exists for RAV4 !!! I had to rent a car for 900£. As I live in France I have to book flights back home (320£) and I’ll have to come back to the UK to get the car when it is fixed. After insurance pays for some of this, it will cost me 1600£. I don’t know who is responsible for the poor protection of this car but I am clearly unhappy about that. Obviously efforts made by Toyota are insufficient. I hope this message will get Toyota to really help with specific short term actions on this. The current situation is just unacceptable for a brand like Toyota.

      1. Thanks for your answer. I like your empathy but it’s not what I expect from a brand like Toyota. I expect specific actions to deal with the problem. I suggest :
        1- Making sure more converters are manufactured as the demand rises because of more thefts and avoid your customers to wait more than a month to get their car repaired. This is costly (car rental) and inconvenient !
        2- Providing a cat lock option when we buy the car or when it has been targeted. I don’t mind paying for it, it’s a fraction of the cost I incurred with car rental/converter replacement. Toyota does that in the US for the RAV4 in partnership with Catshield (see link below). When will Toyota UK do it ?
        https://catshield.com/blogs/news/dealer-direct-protective-upgrade-options-for-toyota-and-lexus-customers
        It would be good business for Toyota and excellent benefits for your clients. Doing nothing but empathy is not enough. We will just by other brands.

      2. Your answer is ambiguous. Saying that CATCLOCs are available at purchase time is right for Prius but incorrect for RAV4. Since I have a RAV4 with stolen catalytic converter, I could NOT have installed a CATLOC when buying it in 2021. As of today the Toyota garage does not think that a CATLOC is available to be installed in the UK for RAV4 ! You need to look at facts and reality, not just making soothing answers full of empathy. Your internet sites now has 91 pages of customers telling you that there are issues and you still don’t take specific actions that would deal with the current reality. Toyota US is doing better than you. Open your eyes and raise your game Toyota UK. Deal with issues or loose customers and damage your hybrid brand before media and/or social networks focus on this topic.

      3. Hi Callet,

        We advised that CATLOCs are available, depending on the vehicle. It is best to discuss the available protective measures with your Toyota Centre.

        We can assure you that we are constantly monitoring the situation and have reduced the precious metal content of our catalytic converters by up to 84%.

        However, we are sorry you feel this way. We suggest contacting out Customer Relations Team.

        Many thanks.

  3. My 2022 Toyota rav 4 had its cat stolen in a carpark at ikea Croydon. Devastated wasn’t the word. This car was designed and developed after it was known to be a problem…. Apparently rav 4s are not targeted- Toyota- yes they are! Further more, there is no available cat lock for it… and you can actually see the dam cat converter sticking out from the bottom of the car – what an invitation! Oh yes I forgot. You put the vin number on the cat converter. Here’s some feedback- that makes 0% difference. Do you think a criminal is going to care? Do you think a dodgy scrap dealer is going to care??? No- and you know it. You’re just paying lip service to the problem by coming up with non solutions!

Paid 1450 pounds last time. Then this time estimation is 1650 pounds. But party not available all over the UK, as per Toyota Blackburn staff. So it can be take 2-3 months.
    Even your Catloc not protected my cat, again you are going to charge higher charge and charge again for Catloc.

      Technically, any vehicle fitted with a Catalytic Converter is at risk of theft. However, this vehicle is deemed as a low-risk vehicle. We recommend contacting your Toyota Centre to see which protective measures are available for this car.

      Thanks.

  5. Hi Guys,

    The catalitic converter of my 08 plate Prius was stolen two daysago. My mechanic is working on the replacement. I try to find a steel plate shield to fit in order to deter thiefs, but struggling to find any. Could anyone recommend anything for me please?

    Thank you

    1. Hi Jojo,
      We are sorry to hear that you have been affected by this horrible crime.
      Your nearest Toyota Centre would be best placed to assist you in getting a CATLOC fitted.
      Thanks.

  6. My catalytic converter stolen first time in December 2021. Then replaced by Toyota , catloc fitted. Again my cat stolen Dec 2022. Useless Catloc protection. First time 1405 pounds and second time 1650 pounds. Increased all the parts and labour cost. Avoid Toyota .

  7. You say that older Toyota’s are at highest risk of cat theft but that newer cars are at lower risk as smaller amounts of metals in the cat. After what year does this risk decrease for Toyota Auris?

    1. Hi Isobel, thanks for your question.

      We wold recommend contacting your Toyota Centre regarding this.

      Many thanks.

  8. Currie Motors Twickenham are CONFUSED as to Whether or Not there is a CatLok for my 2021 Corolla. On 2 Occasions I was able to book CatLok fitting appointments after speaking with PARTS Department on both occasions, but the Dealer called & Cancelled the 2nd Appointment, stating that such an item is NOT Available for my Car!!

    Sent message to toyota.co.uk; No Response!!

    Most probably they make more profit selling a Catalytic Converter than a Theft Protection Device!!

    That’s the bottom line in these Economic Challenging Times!! Each dealership is an individual franchise & need to make Profits!!

    1. Hi Suren,
      We are sorry to hear about the inconvenience this has caused.
      Please provide your vehicle registration so we can check if your vehicle is able to have a CATLOC fitted.
      Thanks.

      1. Please be kind enough to provide an email address so that I can provide my Registration No. as I don’t want to state this personal information on this public forum.

  9. What would be the best means of defence? – i know some people who say a plate would offer the best protection for my Pruis bought in January 2015 Can you comment on this please?

    1. Hi David, thanks for your question.

      Please provide a Vehicle Registration so that we can look into this.

      Thanks.

    2. My cat converter was stolen at 6pm last night. My car was on the drive, CatLoc was fitted. CCTV shows it took them 3minutes!

      1. Hi, thanks for your comment.

        We are very sorry to hear that you’ve been affected by this crime. We apologise for the inconvenience and distress that this has caused.

        We have tried to make sure that as many customers as possible have been informed through publishing police advice about the crime online as soon as it was received, writing to our dealer network to inform customers and writing directly to vehicle owners where details have been available to do so.

        Unfortunately, criminals are using high-grade power tools that are difficult for any manufacturer to completely protect against.

        We would recommend contacting our Customer Relations Team to discuss this further. You can find them here: https://www.toyota.co.uk/help-centre#/iframe/https%3A%2F%2Fforms.toyota.co.uk%2Fcontact-us.

        Once again, we are very sorry to hear that you’ve been affected by this crime and hope that you are back on the roads soon.

        Thanks.
