Wondering if your key has a transponder? A tell tale sign is a large head on the top of the key, a marking on the top of the blade of the key, or a visible resistor on the blade of the key itself. Most car manufacturers hide the chip in the head of the key inside of the plastic or rubber head.
Standard metal keys have minimal security. They can easily be copied at any hardware store.
