Can Keyless Entry Systems Be Made Safer Against Relay Attacks?
Can a car's keyless entry system be made safer without giving up the convenience? Last weekend, I noticed my car unlocked while I was carrying the key near the front door. It made me curious about what practical protection other drivers use against relay attacks.

One thing that changed my routine was keeping my key away from the entrance instead of leaving it on a shelf near the door. I also started looking into how different manufacturers handle signal protection and keyless security. While reading about wireless car security, I came across some information about a keyless repeater box in the context of relay attack risks and vehicle entry systems. It helped me understand why distance between the key and car matters. My neighbour also uses a signal-blocking pouch and says it is a simple addition to his daily routine. I think manufacturers could make things safer by adding motion sensors that disable the key signal when it hasn't moved for a while. That way, drivers could keep the convenience of keyless entry without leaving their cars unnecessarily exposed.
