Renault Kangoo Immobiliser issue

[Vantroublempg]

Do you guys know how to bypass renault kangoo immobiliser as its doing my head in. the red light flashes like its not recognising the key. i try it 4 or 5 times by locking the doors and unlocking then try again everytime until the light finally goes solid red, goes out and then i can get the van going. Im guessing its an issue with the key so either a new key or some way to bypass the immobiliser by adding a connector? Any ideas and prices please
