Peugeot 206 key fob?

Hi
I've just bought a peugeot 206, 1.9 LX D (T reg). Unfortunately the car came without a manual, does anybody know if this model came with standard fit central locking. I have a 1 button key fob that doesn't seem to do anything, i opened the casing to the fob and found that the circuit board has 2 buttons on it. I've read up on how to program the key but unfortunately this doesn't seem to to work.
