when you have entered the code , you need to turn the ignition of then press and hold the central locking button till you hear the door locks make a noise then you need to point the plip key at the receiver in the roof and press the plip 3 times ,also its a little tricky , if you have two plips you need to do this on both plips before the red led goes out on the dash ,if you only got one plip to code in just press annd hold the central button again and start all over , if the door locks dont make a noise , you need to start from putting the code in again.
