i asked the suzuki dealership and they said they'll have to take out the stereo and ship it off back to HQ. and it could be charged up to £150.
Screw that,
Online a few sites said they can find the code if i get them my stereos serial number, just gotta take the stereo out ...
I looked around a few shops locally and a local car audio shop said they can recode it for me, but the stereo is jammed (because my dad thinks his a great mechanic

)
So i had to book in an appointment first thing tommorow morning to get
the whole dash taken off and then they'll take out the stereo, re-encode it for me and put it all back.
All for a nifty £50.
Alot of useless info there but i thought it might of help to some people
