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. Hello Helen,
          Thank you for your comment.
          There is no official Lexus CatLoc available for this model.
          The ISR marking kit is available, but this doesn’t work in the same way as a CatLoc.
          Thanks.

    1. Hello Melvin,
      Thank you for contacting us.
      There is no official Lexus CatLoc available for the NX.
      ISR marking kits are available, but these do not work in the same way as a CatLoc.
      We would recommend speaking to your nearest Lexus Centre to discuss the options available to you.
      Thanks.

      1. If there isn’t an CatLoc for the NX and talking to the Woodford branch would say the same thing. What’s the point? It just goes round in circles.

  1. My cat was stolen from my ct200h – wires to horn cut through grill. My dog had barked the night before – when I checked cctv after the theft I could see my front door had been blocked by a person with a power tool. I was out walking my dog when the theft took place. This level of intrusion is the most worrying luckily my daughter was not aware as it would have made her feel vulnerable in her own home. I am selling my car as I cannot have this happen again. My neighbours have had their ct targeted twice and they have off street parking.

    1. Hello Sabah,
      Thank you for your comment. We are so sorry to hear that you have been a victim of this awful crime.
      This crime is being perpetrated by organised criminal gangs, and unfortunately there is little that can be done to stop these brazen thieves.
      We are working with many different organisations such as the Police, local MPs and the National Lead for Vehicle Crime to try and raise issues with existing legislation, and we have developed theft deterrent devices such as CatLocs to try and protect customers from further attacks. However, determined criminals with power tools can be very difficult to completely protect against.
      We’re so sorry to hear that your vehicle has been targeted by these criminals, and we’re sorry to see you leave.
      Thanks.

      1. The same thing happened to me last night 11pm!
        I have a CT200h , one guy blocked the entrance door and all I could see is his reflection as there was a torch towards him , he had a cap and freaked me out! And the kids too , as I thought he’s drilling through the entrance door. Police arrived within 5 minutes and they reported 3x more catalyst from Lexus were stolen during that 1 HR of me reporting!
        It’s a very scary thing to experience especially for the kids, they didn’t feel safe last night.
        I am going to put in metals gates to the driveway , is Lexus paying for the new catalyst, me not having a car for now with 2 kids , and for CCTV and new metal gate ????
        What’s the point of having a hybrid lexus car ? Please enlighten me as I am losing faith in this brand.

        Woodford branch won’t do shit, you guys don’t even have metal covers for these cars! As if you are in the same bed with the thieves themselves.

        I have to go to a local garage to make one for my car and now I hope the insurance will get this sorted ASAP

        1. Hi Alicia,

          Thanks for getting in touch. We are very sorry to hear that your Lexus has been targeted by thieves, and in such a distressing way. It was right to contact the police, given the threatening nature of the crime that was committed. It is very difficult to stop determined organised criminal gangs but there is a Catloc available for the CT 200h, which your nearest Lexus centre can order and fit for you.

          Again, we’re sorry that you have been a victim of crime and hope you are back on the road soon.

          Thanks

    1. Hi Ken,

      Thanks for getting in touch. As the IS 300h is not a high risk vehicle, there is not a dedicated Catloc available at this time, however, marking kits, tilt alarms and bolt welding are available.

      Thanks

      1. You say that the IS300h is “not a high risk vehicle” – why is this? I have the 2016 model and am wondering if some protection is needed, although my car is in a locked garage at night.

        1. Hi Tom,

          Sorry, we can’t say for sure. Being parked in a locked garage is the best thing one can do, but if you want to discuss more protection, please contact your nearest Lexus centre, so will be able to advise on other potential measures you could take.

          Thanks

  2. Hello

    Please sign the below petition. I know although this crime is a “minority” to Lexus/Toyota/Honda owners please share the hell out of this petition. Action speaks louder than words and we as a community of Victims only a shade below 300 has signed! This crime needs to be on the radar of the Government as with the now the ever growing spate of dog thefts.

    Thank you

  3. The catalytic converter for my 2008 Lexus RX350,( not a hybrid) is going to cost $2500 at the dealership. The OEM part cost is $2200 itself. I need to have a CatLoc device installed to help prevent theft again! Please what is your advice.

    1. Hello Elizabeth,
      Thank you for getting in touch with us.
      As we are Lexus UK, we can only comment on the product availability in the UK market.
      Please contact Lexus in your region for further assistance.
      Thanks.

  4. How do I know if the cat converter has been stolen from my lexus 200ct? Afrew nights ago the car alarm went off at 4am (never gone off before) and then went off again before we could got outside to look/cancel it ourselves. I therefore want to check.

    1. Hi Sarah,

      If the catalytic converter has been stolen, there would be a very loud noise coming from underneath the car when the petrol engine switches on.

      Thanks

  5. I don’t have a driveway but I do have a front garden. I love Lexus soo much that I want to remove my front fence so I can park my next Lexus (CT or IS300h) I buy on the grass. My question is, as the thieves need to jack the car up, surley if parked on grass they cannot jack the car up to steal the catalytic converter???

    1. Hi Darius,

      Thanks for getting in touch. It is hard to say exactly what lengths these organised criminals will go to when stealing catalytic converters. You would think that a car parked on grass would make it more difficult, but we can’t promise that it won’t get stolen. Sorry about that.

      Thanks

    1. Hello Victor,
      Thank you for contacting us.
      There is a CatLoc available for the RX450h, along with an ISR marking kit, a tilt sensor and bolt caps.
      These can be purchased through your nearest Lexus Centre.
      Thanks.
