nop. didnt alert at all.. i m using 2-way alarm and my car was just 1house beside. my car did not alert, and my receiver in pocket did not alert. all i found is a piece of broken glass. no idea how they did it. drove away silently. here is where those car with super car loud ezhaust are safer, if ur alarm didnt alert for attention atleast ur ezhaust do. anyway just joking. felt really really really x100 pain actually but nothing more could be done. will never trust in alarm anymore.
