Top 10 Car Key Signal Blocker Security Cases

Keyless entry and starting for your car is convenient and user-friendly, but it does leave you vulnerable to hi-tech thieves. These criminals use relay attack devices to ‘read’ the key from outside your house. With the code copied, they can simply drive off in your vehicle. Storing your key in a special bag, lined with layers of metallic material, is the way to foil them and keep your car safe. The key needs to be placed inside the bag from the moment you plip the locks. It can also be used for contactless credit cards to prevent hacking and fraud.
