Does this occur immediately when you lock the car, or afterwards?If you trigger the alarm does the siren sound correctly then? Have you got the factory fit alarm, or the Vauxhall accessory fit DSA alarm?

Sorry for all the questions, just trying to pin down a few things before spouting suggestions to you!
