KUNIO Dedicated Relay Attack Prevention Key Case: Prevents relay attacks for smart keys
This smart key case is designed for Lexus owners who want to protect their vehicle from relay attacks while maintaining easy access. It's perfect for urban commuters who park in public lots or residential areas where car theft attempts are a concern.
While most key cases focus on basic protection, this one offers a unique perspective: it's not just a security device but a seamless part of your daily routine. The carbon PU leather feels durable in your hand, and the internal chain keeps your key secure without adding bulk to your pocket. You can quickly attach the carabiner clip to your bag, so you never fumble for keys when loading groceries or heading out.
The water and dust resistance means it holds up in rain or dusty conditions, and the smoked clear cover lets you check your key's status at a glance. Compatible with Toyota, Honda, and other major brands, it installs easily with the included tools. Choose from colors like blue, red, or black to match your style while keeping your car safe.
