just incase anyone has this same trouble. i've actually fixed it "I think". i rang the shop up again and they gave me a quick fix option, but all the functions still work and seems all good. firstly i had to turn the ignition to accesories then back to the off position, after that there a little button on the right kick panel of the drivers door, i pressed that in and it goes into "Valor mode" the guy said. and it resets the alarms configuration. so they didnt stuff up the wiring it was just a dodgy config im guessing. so if anyone else gets this problem, i hope this also helps you
