Where i live there are a lot of stupid kids that like to play in other people driveways, ditching their bikes, throwing things, and chasing eachother around peoples cars. I also have a pretty nice pioneer deck in there that I would like to keep. This and the risk of leaving my car in other places like school and downtown brings up the thought of a car alarm for me.

I do not know much of anything about them, but i do know what i want, I want one that you can easily change the sensitivity of it, and is reliable, i want it to be able to unlock my doors with that cool keypad if possible, i also want to be able to lock my doors, and get that cool little chirp . I saw one somwhere that said that if it was tapped lightly, it would only go off for 3 seconds and then stop, but if it was hit hard that it would fully engage, this would be nice, cuz my step bro has one that goes off if somone goes by with their system turned up

So any sugestions, tips, advice, etc would be great.

Thanks,

Matt
