Unfortunately, there are a number of documented cases of RAV4s being stolen via what's known as a CAN Injection, where the vehicles CAN (or Controller Area Network) is tricked into thinking that a key is present due to bridging some of the wiring loom connections. Toyota in the UK does not confirm the situation but it has been widely discussed online. However, there are other models that are also prone to cyber theft thanks to cars relying more and more on online systems, with Land Rover models also prone to theft. Most car thieves are opportunists, which means a good old-fashioned deterrent such as a mechanical steering lock is a good idea.
