what you have to remember is no matter what you do if they want it bad enough they will take it, i have a mate who put an all singing and dancing alarm on his van,grills up the windows,yale locks and armaplates on and he came out of his house onto his security light drive to find the door had been forced open by bending the the B pillar away from the door the alarm had been disabled but nothing had been taken, instead a note had been left on the drivers seat saying "see if i want it i will take it"
by the way they had even laid straw on the gravel to stop the noise
