Digital car keys: Convenient, but vulnerable
Car keys have long since ceased to be simple metal objects that only serve to unlock and start your car. In the digital age, modern car keys have become complex devices that use wireless technologies, and with these advanced technologies also comes a certain vulnerability.
Digital intrusions
Modern car keys use wireless signals to communicate with your car, usually through a technology called “keyless entry” or keyless entry. This means they are susceptible to digital intrusions. Criminals can intercept these signals and use them to steal your car without physical access to your keys.
Relay attack
A common method used by criminals is known as a “relay attack.” This involves two thieves working together. One thief stands at your house and tries to capture the signal from your key, usually through a special device. The signal is then sent via a wireless connection to the second thief at your car, who uses the signal to unlock and start the car.
Code scanning
Another vulnerability is scanning the code your key transmits. Criminals can stand close to you, scan the code while you unlock or start the car, and later use it to steal your car.
Protection against vulnerabilities
While modern car keys can be fragile, there are steps you can take to protect yourself. Keep your keys in a safe place at home, preferably in a metal box or wallet with RFID blocking to block the signals. Also consider taking additional security measures, such as a steering wheel lock or a GPS tracker for your car. To avoid getting into awkward situations, it is useful to have an extra car key made in advance in case the original one stops working for some reason.
Finding the right balance with car keys
Modern car keys are sophisticated devices that offer convenience, but they are also vulnerable to digital intrusions. It is important to be aware of these vulnerabilities and take steps to protect yourself from car theft. It is a matter of balancing convenience and security in the digital age.
