Using the Noble Pro Suede Keychain Cover is a breeze. Just slide your key into the suede cover until it fits snugly. You can then use the quick - release key ring to attach other keys to it. When it comes to maintenance, you can gently wipe the suede cover with a soft, dry cloth to keep it clean. As for storage, keep it in a dry place to prevent the suede from getting damaged. Remember, this cover may slightly reduce the range of your key's signal, so if you notice any issues, you might need to hold the key closer to the sensor. Also, always double - check your key against the third photo to ensure compatibility, as not all models use the same key type.
