After Market Alarm

I just bought a 2008 Cobalt ls four door. I am getting an alarm/remote start installed, but this guy is tellign me I need a bypass module for another $60 or something like that. Does anyone know if this is true??? I dont have auto locks and my key doesnt have any chip in it or anything and I thought that was what the module was for to bypass that, can anyone help me here?

You do need the bypass module, all of the newer GM vehicles have the Passkey security built in.

Does the 2005 have Passkey?? I have no power anything, it's just the base model. Also how does an after market alarm hook up to doors/ windows? With the more stuff I'm putting in my car I want some security.

It does depend on the alarm system any decent one should have pin switches for the doors, hood and trunk. As far as the windows go that depends on whether or not it has an impact sensor it would go off if one of the windows gets broken. Whatever you get just make sure you have it done at a good shop. There's nothing that can cause more problems than a badly installed alarm.

What If i install myself, or is that near impossible???

[dtadla]

impossible but unless you've got experience with that kind of stuff not recommended especially since most alarms have a kill switch meaning that if the alarm goes off it kills the ignition until its disarmed and if thats done wrong nothing good can come of it. I would highly recommend checking the shops around you. especially if there are any good stereo shops around you. its definately not a job for a novice.

I was looking at getting an alarm installed on my car when I get home from deployment. I have the same set up, no power anything. I have a shop to go to already that installs with warrenties. They only offer viper alarm systems, but are willing to install a different brand if I get it. My question is, what brand would anyone recommend?

If you're just looking to install an alarm then there shouldn't be any real problems, but if you're putting in the remote start then you're definitely going to need dealer help(bypass).

Most alarms have you run a bump sensor and a wire to your interior lights... so if someone breaks a window then the alarm goes off, or if someone opens a door then it also goes off.

so anyone have a rough guess to how much a pro job is. just for an alarm not a remote start.
