Keyless car systems are remote devices that are used to control car systems such as ignition and doors.
They use unique low-frequency radio signals to communicate with a car’s computer system.
Sensors in the car let the user open and close doors and ignite the car without manually putting the key in a keyhole. It is for this reason that they are called ‘smart keys’.
Benefits of keyless systems include igniting the car, lowering and raising windows, folding mirrors, and opening the doors and boot of the car.
However, there are risks to keyless systems that users should be aware of.
Kenyans.co.ke sought to explain three risks of using the gadget. They include:
Hacking
The radio frequencies used to operate the system can be used to hack the car system and steal it.
Electronic Control Units (ECU) are automotive electronics that control one or several electrical systems in a car. The systems include the engine, entertainment systems, and navigation.
According to motor industry experts, Dubizzle, many keyless cars have been stolen through hacking
“Hackers can get control of your car using the signals from your keyless remote. The encrypted radio signal can be cloned into a counterfeit key.
“To prevent such attacks, it is advisable to keep the remote control away from your car’s radius,” state Dubizzle.
Accidents
Compared to manual car system, drivers have to turn the key switch off and exit the car
Keyless car owners face the risk of leaving their cars without engaging in the car parking brake.
This may lead to leaving the car engine on for far too long, thus, consuming fuel and producing excess carbon monoxide.
Phishing
Hackers can tap into the car's Wi-Fi system then use it to access email addresses and devices such as phones then send phishing messages to the email addresses.
“Cyber attackers can access your car through its Wi-Fi.
“They can spam and send malicious links to your email and into your phone connected to the car’s Wi-Fi,” noted Dubizzle.
Car owners are advised to seek the advice of ECU experts if they suspect their keyless car systems have been hacked.
Furthermore, they should park their cars in safe parking lots to avoid being hacked or tampered with.
