Sounds to me like the alarm is faulty.  That does happen.  It can't be much of an alarm, though, if the man was able to get at it and disconnect it - or did he disconnect it after you came back?  That's not quite clear in your question.  Was it built into the car as part of the original build, or was it a cheap add-on fitted by someone else?  If it's a Vauxhall original, a dealer should be able to fix or replace it.  If it's the other, remove and throw away, or at least leave it disconnected.

Ewood27 thanks for your reply,the alarm is a vauxhall factory fitted, wife had a slight shunt a few days before and wondered if this somehow affected it,if i disconnect the car battery would this reset the logic

Rayman - A friend of mine had the same problem with his GSi after someone nudged the back end. Spent weeks ripping his car apart because the battery went flat all the time and then found out that the light in the boot wasnt turning off when the boot was shut. Removed the bulb - problem solved. Give it a whirl!!

Also if its a crappy old alarm on the car get shot because it'll give you nowt but grief and not put off any tea leaves........

I'm not qualified to answer in that much detail, Rayman.  It could be that your wife's shunt did cause a short circuit or something.  I think the Vauxhall dealer is the route to follow.  I'm not sure that disconnecting the battery would do anything to help.
