lock on lock off

With the price of gas going up and up it seemed like a good idea to invest in a locking gas cap for my car. I found that there are two types of locking gas caps now available. The first kind needs a key to lock it in place and then the same key to remove it. The problem with these is that if you loose the key, the gas cap can not be removed. The second type can be locked on or if the key is lost, used as a regular gas cap and screwed off. If the key is lost while the cap is off you can still use it.
