How 'Smart Keys' Have Fuelled a New Wave of Car Crime
Car theft is a serious problem affecting millions of drivers worldwide. Sadly, New Zealand is not immune. According to the latest statistics, 2023 was the second-highest year for vehicle theft in New Zealand in the past five years.
One reason for this alarming trend globally is the rise of keyless entry systems, also known as 'smart keys'. These devices allow drivers to unlock and start their cars without using a physical key by pressing a button or approaching the vehicle with the key fob in their pocket or bag.
While these systems are designed to offer convenience and security, they have introduced a new challenge for car owners and manufacturers. As often happens with technology, criminals find ways to exploit it, and, in this case, they have, allowing them to steal cars without leaving a trace.
Thieves use two common methods to carry out keyless car thefts, also known as relay thefts. The first involves using a device called a 'relay box', which can capture and amplify the signal from the key fob and transmit it to another device near the car, tricking the car into thinking the key is present and unlocking the doors. They then drive away with the car or use another device to clone the key and disable the alarm.
The second method involves using a device called an 'emulator', which can intercept a signal from the car, which is scanning for the presence of a legitimate key. It then sends back a signal to the vehicle enabling unlawful access. This device can be disguised as a handheld games console and can be used to mimic the electronic key on specific models of car.
These devices are traded online and are used by organised crime gangs, particularly, to target high-value cars. Some can even bypass the latest security features, such as encrypted and rolling codes, that car manufacturers have introduced to prevent keyless car thefts.
Car owners with keyless entry systems are advised to take precautions to protect their vehicles from these sophisticated attacks. Some of the recommended measures include:
Using a signal-blocking pouch or case to store the key fob when not in use. This will prevent the thieves from picking up the signal and copying it.
Turning off the wireless signal on the key fob if possible. Some key fobs have a button or a switch that allows you to disable the wireless function when you don't need it.
Parking the car in a secure garage or a well-lit area with CCTV cameras. This will make it harder for the thieves to access the car and deter them from trying.
Using additional physical security options such as steering locks, wheel clamps, or alarms. This will make it more difficult for the thieves to drive away with the car even if they manage to unlock it.
Keyless entry systems are a huge leap forward in convenience. However, they introduce new risks, which if not managed, can be exploited by criminals. If not, they may find their cars gone in 20 seconds
