Update on this:
I did not look to make a new key as i personally think it wouldn't have worked as all locks opened just fine with that same key except the ignition. So probably just the ignition barrel wich was broken-worn(if that's possible)
I started drilling the entire ignition barrel out, i have to say i was pretty much afraid as i didn't want to make it any worse than it allready was. But it was an easypeasy job, took me about 5 minutes. I allready had a different lock with key to fit in wich i bought for about 30£. So this problem got fixed easy and quick. I just didn't have the guts to start drilling untill today.
I am very happy now as i can hear the supra again
Thx for all the help
