This 2-pack of signal blocking RFID keychain protectors is designed to protect your vehicle by blocking signals from a wide range of transmitters. Made from premium carbon fiber and RFID fabric, these keychain protectors are both durable and stylish, and feature a sleek black design that complements any aesthetic. Our keychain protectors are available in two convenient sizes to fit your needs. The small size (4.9" x 3.2") is perfect for a single keychain, while the medium size (5.5" x 3.6") is perfect for access cards or other small electronic devices like garage door openers or smartwatches. This versatility ensures you have the right size for any situation. The keychain protector also includes a larger U-shaped hook, allowing you to hang it anywhere for easy access. Plus, we include an extra key ring for storing additional keys that don't need to be blocked, keeping all of your keys organized and secure in one place.
