My car alarm, on my vauxhall frontera sport, 2000 reg. keeps activating for no apparent reason, sometimes straight away as soon as it is activated or from 2 hours to 2 weeks, day or night. Have had to disconnect the battery at night to stop the alarm sounding in the middle of the night. Any ideas?

Take it to a dealer or diagnostics tech and get the alarm codes checked.
