Lost my immobiliser fob

[Mark Quinn]

Hi ladies and gentlemen! 

Im just new, I bought a Subaru Impreza wrx classic 2000 and I managed to get 6 points in it and lose my licence cut a long story short... while it's been off the road I've lost my immobiliser fob! So not sure how about getting a new one, will I need to go to Subaru to get a new one or is there anyway I could get someone to code a new one for cheaper, as I seen it's about £400 for a new key and fob! 

Any help would be apriciated! 

Thanks in advance 

Mark
