A strange thing happened to my neighbour last month: his car was unlocked overnight, even though he was sure he had locked it. It got me thinking about keyless entry security. Do you use signal-blocking pouches or any other simple precautions to keep your car protected when you're not driving it?

I also started using a Faraday pouch whenever I leave them at home. A friend who works with vehicle security explained how relay attacks can work, which made me pay more attention to everyday habits. For anyone interested in electronic security equipment, I came across some information about an eas jammer, although that's designed for electronic article surveillance systems rather than protecting keyless car entry. For vehicle protection, I'd focus on tested signal-blocking cases, checking that the doors actually lock, and having a mechanic review the keyless system occasionally. These habits are easy to maintain and give me more confidence when parking overnight.
