well it all started when the power steering took the knock on my astra van then the battery light came on, so off to the garage the van went he put a belt and belt tensioner on it. when i collected it ,it was still the same so he suggested i take it back the next day so he could have a look at it. the next day i goes to get in the van clicks the alarm button and it wont open, my van has a total closure alrm on it and to make it worse the key remote wouldnt work either.so i decided seeing how the drives door has been de locked il open the hatch climb in and re set the alrm of the igniton, guess what the key wont open the hatch.so i had to break the passanger window to get in , not a happy bunny , but the vans all fixed now
