Catalytic converter theft: what you need to know

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 the case of Lexus, we are aware that the second-generation Lexus RX 400h models (2005-2008) and the Lexus CT 200h have been a particular target for thieves.

Below we’ve gathered the best advice for Lexus 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 catalytic converter by law.

Why are they a target for thieves?

The police are best placed to offer advice on the motivation behind crimes. But we understand that the recycling value of catalytic converters is the primary 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 a 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 had my cat stolen yesterday in a public car park. I own a 57plate rx400h
    Please tell me what I should be paying to have it replaced by lexus please. DON’T give me your altermated reply saying to contact my local dealer! Reading this forum, there are many different prices, I want to have Lexus give me an official price reply please.

    1. Hi Sam,
      Thanks for your comment.
      We’re truly sorry to hear that you have been a victim of this crime and fully understand the frustration and concern that you are feeling.
      The reason for directing you to your nearest Lexus Centre to gain a quote for replacement is that the vehicle will need to be assessed to understand the damage caused and the extent of the labour required to fully rectify the problem, which can not always be foreseen.
      Lexus Centres are also able to fit a Catloc system which further protects the part and acts as a deterrent to thieves.
      You can find your nearest Lexus centre, here: https://usedcars.lexus.co.uk/en/dealer-locator
      Thanks.

  2. Hi!
    I, too, have my catalytic converter stolen in the night of 20-21 September whilst parked in a public car park.
    This is very disconcerting to find oneself victim of such a criminal theft.
    I will be contacting Lexus to take the next step. My reg is RO08 WFG.
    This issue must DVLA notifying Lexus drivers for awareness as soon the car is taxed.

    Thanks.

  3. Hi , My Lexus CT200 catalytic converter has been stolen yesterday (22 September 2020) which is absolutely heartbreaking. I wish the dealer could fix this as free of charge as no advance warning has been given. Also, in LEXUS website it only states that Lexus RX400 H model only has been targeted for thieves. Please kindly advise how I can sort out this problem within a reasonable price.
    Thanks

    as per Lexus comment above you can provide Catloc system especially for CT where I can order that ?what’s the price? And why you r not advising your customers to get one at the point of sale or fit them generally if you know that is the common issue?

  5. Luckly, yesterday day evning(23/10/2020) they try to steal I think the catalyst converter from my Lexus CT 200h 2012model, I caught them when I heard them while they start to rip the front grills
    I call this moring my local dealer to replace the grills and still waiting to confrim the time

    I hope they will not charge me arms and leg for the grills and for We have taken action to produce CatLocs for vehicles most at risk, and there is one available for the CT.

  6. Hi I have an NX200 bought new in 2020. Is its Catalytic Convertor likely to be targeted – and if so is there a Catloc for this Model yet please ?

    1. Hello John,
      Thank you for contacting us, and congratulations on your new NX. We hope you are enjoying it so far.
      The focus of this crime remains upon older vehicles, and this is due to the higher percentage of precious metals in the catalytic converter.
      Newer vehicles, such as your NX, feature a significantly lesser proportion of such metals and are therefore less attractive to these thieves.
      CatLocs are available for current high-risk vehicles, and this does not include the latest NX.
      Thanks.

  7. I agree with all the people on here. If we are paying so much for the car, why are we not advised at the point of sale where we are paying thousands that another £250 for catloc is throughly recommend! We were sold from the Woodford branch and we would have happily paid the extra £250, instead of being a victim of this heinous crime, where the police nor Radisson hotel in West Drayton ( where it was stolen from ) are able to assist.

    Another question I have is the design of these cars. Why are the Cats exposed on the underside and not protected from within!

    Thanks
    Heartbroken person

  8. Hi
    I have been a victim now as my Ct200h catalytic counter stolen last night on 30th Oct. 20.
    They cut my front grill and reaped up my bottom
    cover of converter. I tried to contact Lexus LexusTwikenham and they are quoting me £2000 for repair.
    Is this correct Price?

    1. Hello Mario,
      Thank you for contacting us. We are so sorry to hear this.
      Prices tend to be higher closer to the capital as there is a higher number of at target vehicles in this area.
      You are welcome to visit an alternative Lexus centre for a different quote.
      Thanks.

  9. Hi
    I am due to purchase a GS300h (either 2016 model or a 2018 model).
    What is the likelihood that I might be at risk of CatConverter thieves?

    1. Hello T,
      Thank you for your comment.
      We produce CatLocs for vehicles currently deemed as high-risk targets, this being the 2005-2009 RX 400h and the CT200h.
      Whilst the later models have catalytic converters which feature a lower percentage of precious metals, we cannot make guarantees as to whether a vehicle will or will not become a target for these brazen thieves.
      Thanks.

    2. Hi I have a brand new RX can I fit anything to cover the catalytic converter to add extra protection from thieves ?

      1. Hello Debbie,
        Thank you for contacting us, and congratulations on your new vehicle.
        There is no official Lexus CatLoc for this model as we currently only produce them for vehicles targeted by thieves.
        Thanks.

  10. Hello. Mine was stolen 2 days ago at 9pm in front of me and some neighbours that went out. The thieves with masks and a bat in ones hand did not care about me calling the police, my neighbours as witnesses or the alarm going off. There were 3 cats in their car boot, stolen the same evening in my area. They also had cloned number plates, so that doesn’t help the police. They left in around 2 minutes leaving me with in shock, a big expense waiting for me, £350 excess , raise in my insurance premium and who knows how much a cat lock is going to cost me too. Also the stress and time to organise repairs and getting a car to be able to go to work.
    After seeing all the comments above, I am shoked to see how much it happens and how little is being done to prevent this.
    Why is Lexus still selling these unsafe cars and why are we not informed of this risk before we invest our hard earned money?
    If this is a known risk why are the cats not secured before they are sold?
    If Lexus is not making a profit, wouldn’t it be better for them to just secure them to prevent?
    And most of us victims are supposed to pay for all this only to be robbed again?
    It happens anywhere and anytime, we are not save at all. I am so disappointed.

    2. It’s a shame no law has been put up to discourage the sales of these stolen metals for cash it should be a criminal offence buying or selling these metals that everybody knows where they coming from a poor car owner who’s been left in there to pay the bills for who’s wrong of course not theirs …
      And Lexus can definitely put up some sort of protective clamp to make sure the thieves stealing it is not a walk in the park.

      1. Hello Mahin,
        Thank you for your comment. We know how upsetting this crime can be, and are really sorry that you have fallen victim to these criminals.
