Catalytic converter theft: how to protect your car

By LEXUS 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. As regards the Catloc, is there one available for the Auris, as our local police force is saying the Auris is being targeted as well as the Prius.

    1. Sorry, but I know someone who HAS had the catalytic convertor stolen from their car whilst parked in a car park. Also one police force is naming the Auris as one car at risk .

    3. I know of one person who has had the catalytic convertor stolen on their Auris. Also on Toyota Owners Club, two members have posted that their Auris’s have had theirs stolen. So whether the cats are exposed or not, some are being stolen.

      1. mine’s been stolen too today, I just want to know if I claim from the insurance, will the insurance be very high.

      2. Hi,

        Sorry to hear that your vehicle has been targeted by thieves. We recommend contacting your insurance provider for more information.

        Thanks

      1. Hi there,

        Thanks.

      2. This site is pathetic and all we see is “I am sorry bla blah blah” I have just had my catalytic converter stolen and this twice within space of under a year. I have a Prius 2008 and my insurance range covered the cost first time and cannot afford to get this covered again by insurance company. I was a big fan of hybrid cars but now would not recommend anyone buying a Toyota hybrid car. Not worth the hassle when even your own dress veway is not safe. I would not even advise on fitting a catloc as this did not deter the thieves stealing from my car. I would not even consider buying a Toyota car and will be telling my peers He same thing.

  2. Hi just stumbled across this. My wife’s 63 reg Auris Hybrid was targeted today at train station car park. Found the bottom panel removed so looks like they are targeting the Auris too 🙁 Will there be a Catloc for it?

  3. My cat got stolen on Friday! I really want to get one of these catlocs fitted as soon as possible.
    I’m bloody furious at how easily the scumbags can steal them.

  5. My wife had the cat stolen from her 2014 Auris at Leicester University car park on 21st June. It was the 5th Toyota hybrid targeted that week in the area.

    I have contacted my Toyota dealer and they have told me there is no catloc available for my vehicles (2014 Auris and 2017 Rav4). I then contacted Catloc directly and they told me I could choose from one of their generic models, but I wouldn’t be able to return it as they do not specify for my cars.

    I would be happy to pay £200 for a security device, but there is nothing available. Toyota you need to be supporting all your hybrid customers!!!

  6. Yes, my 2015 Toyota Auris was parked in a public Park and Ride with plenty of security cameras. It didn’t deter the thieves on Tues 9th July. I filed police report and insurance covers damage but I still lose due to my excess and increased premiums. **Toyota… this is something your customers want urgent action on! ** Step up now!

  7. Cambridge park and ride carparks being targetted, primarily the Prius. These sites are supposed to have CCTV but people are being led in to a false sense of security because the cameras do not always work and the staff fail to notice even when a van/car must be stopping several times, next to the target cars, to do the theft. I am advised that all it takes is the time needed to jack up one side of the car, break the plastic clips, cut through one or two other clips, remove a bolt and force off a cover plate.

    Not only do Toyota need to bring pressure to bear to collate the known information from the CCTV images – there is more than one camera – but all drivers should have been offered the catlock FOR FREE as a method of protecting the reputation of the Prius.

    This theft, even if insured, is going to cost a lot of money, it has caused the cancellation of appointments – for which I might be charged – , the altering of ferry information (for which a service charge will be levied), and it has wasted NHS money because it was not possible to reach a pre-booked appointment for a routine cancer screening test, which will take weeks to re-book. Tomorrow I will have to grovel to the surgery and apologise for wasting the time of the receptionists, the data entry clerks and the practice nurse. A single missed appointment is probably another £100 which might have gone to healthcare if I hadn’t been sitting miles away, out of hours, waiting for a tow-truck. The extra miles clocked up in one night by tow trucks and onward cars – there were at least three thefts that I know of – was all energy which need not have been expended.

    Theft is not a victimless crime which is covered by insurance. It passes hundreds of thousands of pounds worth of damages on to the wider society.

    Toyota knew about this potential problem but took no opportunity to warm me of it, denying me the chance to make an informed choice about the catlock. Why, then, would I look at any Toyota when the time comes to replace the Prius. It appears the Auris is similarly vulnerable.

  8. I have had my Cat stolen from my 2018 Auris in Royal Derby Hospital Car Park on 15 July. Dealer says there is a delay in getting replacement. Toyota needs to find a solution for this model as well.

    2. Nearly 2 months down the lane and my Dealership keep failing in their promises to make a repair due to failings by Toyota to deliver the necessary parts. It’s about time Toyota UK made a decent offer of compensation to its very dissatisfied customers. How about a new Corolla which is being heavily promoted at present.

    1. Hi John,

      Thanks for getting in touch. At this time we don’t have any plans for a Catloc for the Lexus CT as it is no more susceptible to theft than any other manufacturer. We do however monitor the circulation of vehicles and those deemed a target for criminal activity in order to take proactive action.

      Thanks.

  10. I am sitting in my car at moment waiting for my car to be towed my Auris 2017 has had its cat stolen this morning. When I went into hospital to work at North Middlesex hospital in North London.
    It’s gonna cost me excess to get this replaced which can’t be recovered.
    I don’t see why owners have to pay for these deterrent devices to be fitted as it should be part of the vehicle as this is a known issue and it would save Toyota money in the long run and give people more confidence in this situation which I would not want to happen to anyone.
    I guess they have not released one for my car yet but this is a nightmare if you have to pick up kids from school and also not being able to get home.
