Yes, keyless entry systems can be hacked through a method called a 'relay attack'. Thieves use devices to intercept and relay signals from your key fob to your car, tricking it into thinking the key is nearby. To protect yourself, consider storing your keys in a metal container or a signal-blocking pouch to prevent signal transmission. Also, regularly updating your vehicle's security software and considering traditional steering locks can add an extra layer of protection against such vulnerabilities.
