you should only need one key if you have the red key and two keys if they are blue.
Cant remeber the exact way to do it but try turning the ignition on and off 10 times until it bleeps (with red key) and then put in your new key (blue key) and turn the ignition on and off and then it should program the blue key. wait 20 seconds before trying to start the car
