Does cruise control actually save fuel?
Cruise control can save 7–14% fuel on a flat highway. On a hilly road, it can cost you more. Here's when to use it and when to turn it off.
Are keyless start cars really easier to steal?
Even though it’s been around for years now, keyless ignition in a car still feels pretty futuristic. You press a button, the engine roars to life, and your car key doesn’t even need to leave your pocket. You can unlock your car by simply walking up to it. But of course with every new tech, there comes ways to exploit that tech. Keyless start systems are no different, with thieves finding ways to steal a car without ever setting their hands on the physical key. So let’s take a look at exactly how it works – as well as some practical tips for prevention.
How does keyless car theft take place?
Keyless entry and start systems work because the car’s key fob constantly emits a low-frequency radio signal that has a code unique to that car. When you bring your key fob close to your car, the vehicle recognises that signal so you can gain access.
One common way to exploit that technology is to use a ‘relay’ method, which tricks the car into thinking the key fob is closer than it actually is. One thief will hold a relay device close enough to the key fob to pick up the signal, often standing just outside the front door close to where keys are often kept. The thief’s relay device transmits an amplified signal to a second relay device being held close to the car by a second person. The signal is extended from the fob to the car, allowing the thieves to unlock and start the vehicle. Here’s some footage from the UK that shows this in practice:
Another increasingly popular method involves using a reprogrammer device to clone the key fob data, then using this to access the vehicle. In some instances, electronic devices are plugged into a car’s on board diagnostic (OBD) port to override the security system and start the car. It’s like hotwiring, but with code!
Of course, these methods can lead to keyless car theft (with the aim to either rekey the car or chop-shop it for parts), but also pilfering of anything else left in a vehicle like wallets, laptops, tools and other valuables. In recent years, the devices used for keyless car theft have become far cheaper and easier to buy. We’re talking as cheap as $30! Unfortunately, some garage doors can be remotely opened using the same type of technology.
In this sense, keyless car theft has quickly become easier than ever.
