Sorry, should have said, i have to hide the keys in the car! The actual nuts are on the wheels, (surprisingly enough)
You have to keep the key/s in the car in case you ever get a flat or need to take the wheels off when your away from home, but always hide them so pikeys cant find them and steel your wheels!
I need two keys, one for the actual wheels on the car and one if i ever need to put my spare on, as its a different type wheel, hence, different key!
