Laguna Keycard?

My Laguna 2001 key card open and closes the car fine but recently when i insert the keycard into the slot the red light on the dash just flash's and wont let the push button ignition start the car. But today i caint start it at all, all that happens is the red light flash's and the radio comes on but thats it.

Please help as its just cost me £1200 to get it on the road after a list of problems.
