Well, I'm starting to research a security system for my 09 2LT, now that i have subs, a nice head unit, a $478 GPS etc.. I'm also going to be getting the windows tinted soon as a minor deterrent (and for aesthetics! ) But my question is can anyone recommend a good system that isn't insanely expensive? best bang for the buck. - or also something that works well with our cars?

I also want remote start if possible, but is not entirely necessary.

What about something like this? this kit upgrades the factory anti-theft system on 2006 and up GM vehicles it states. instead
of wiring in a WHOLE new system, it uses the factory databus wires and makes the install a WHOLE lot easier. I still have to call to see if it works with Cobalts but if it does, this could be a great option.

Thanks!
and Merry Christmas guys!

 

I didnt even think about a GM enhancement... good thinking.
Ive got an 08 that just has keyless. i just ordered a python 872P from amazon for like $180 with remote start, a slick key fob, and tons of features. Im still researching though and im thinking i need an xpress kit to connect the alarm with the car wiring quickly/effeciently, but im not sure if i still need an ignition bypass or not. damn, this is getting complicated fast! where are the aftermarket alarm guys on here when you need one???

Seriously, it is really confusing - I find it hard to believe no one has a security system on their car and if they do, why they are not posting! haha

 

Ok I'll post up to try and clarify some things. First I would avoid the upgrade part, never really cared for them. I prefer directed electronics gear, mainly viper or python. Even avital is a cheaper option if you don't want to spend a ton. I have a viper 5902, which Is the best one they have out, but there are plenty of options. Look up directed online and you can find all of their brands. You will need an Immobilzer bypass for the pk3, either a dball or fl-can which I recommend. Installation is not for a novice, remote starts and alarms are challenging. The bypass is only needed if you are doing remote start. I have been installing for 5 years so any questions let me know.

 

Thanks man, I appreciate the information. - I'm only looking to do a security system, not remote start as well. Do i need any sort of integration module or anything along those lines for just security? Or do I just need whatever comes in the box, and then bring it to an installer? - Also, just because the security system has the remote start option doesnt mean i have to install that option correct? I can still use just the security feature.

 

correct. you do need a bypass module and the one u would need for security only is much cheaper then the remote start one

 

You don't necessarily need a module if you are only doing security/keyless. Don't get me wrong, it will certainly make things easier but you can get away without it.

 

Where would I get said module?

 

They don't actually make just a door lock interface for our cars. The only options are transponder only, or combo modules which do both locks,triggers,etc, and transponder bypass.So unless you are actually going to install a remote start I'd say just don't worry about it. Take the unit to an installer and they can tie into your locks, door triggers, trunk trigger manually. Honestly if you aren't doing a remote start, buying a bypass module is just a waste of your money.

 

I have a Python system on my ION. If you are wanting to protect your car don't cheap out on the system. If you're not going to cheap out on the things you put in your car (i.e. sub, gps, HU) then don't cheap out on the system that you want to use to protect those things... Just my 2 cents

 

im waiting on the python 872. I plan on getting the xpress kit for easy/cleaner install, but will i need an ignition bypass? ive also heard of needing a spare key for the ignition bypass. just wondering what all i should order.

 

how so? if you tie into the door/trunk triggers and the car has an OEM alarm it would set off the factory alarm if the triggers got a signal from the aftermarket alarm right?

 

you don't need a spare key...the bypass module will take care of everything for you. youll have to use 1 relay though.

i used the dlpk.

 

No, no it will not

 

didn't know that....interesting.

can you explain why not?

 

i got a bypass module a couple days ago and im getting the install done tonight. hate to be all like here but i have to ask, what is the 1 relay for?

 

off of the transponder harness (right near the ignition harness, just 4 wires, very thin gauge) is a red wire (on an 06, please look it up to verify before you install). cut the red wire. put one end on 30, one end on 87a. the status out (-) aka "while running" wire coming off your remote start goes to the 85 terminal, and 12v constant goes to 86.

just make sure this applies to your year/install before doing it. I used a dei remote start alarm with a dlpk xpresskit bypass module.

 

The car just uses a negative signal for triggers, and so your aftermarket system will work based on what type the car uses. So if you arm the vehicle with an aftermarket system and it sees a door trigger it won't set off the factory alarm because it was never armed to begin with. Does that make any sense?

 

I have the viper smart alarm... My remote is my iphone

 

well, then you're paying too much for an alarm remote that drops allll those calls.

got my python 872 installed last night. pretty impressed. on crutchfield for $450. on amazon for $160!

 

I paid $300.00 installed plus an tilt sensor

 

i understand how door triggers work, but on alot of cars i see people tap only into the door triggers and not integrate the oem and aftermarket alarms by tapping into the oem arm/disarm. just to clarify.

 

I don't see why you'd be concerned about oem arm/disarm if you are adding aftermarket security. I know why you'd do it just for remote start, but since you have an aftermarket alarm why tie in with factory security?

 

just in case the customer loses his aftermarket remote and is forced to use the OEM one. esp. on our cars where the key tumbler on the door triggers the alarm and the remote is crucial in disarming said alarms. just saying. but yea practically i agree what you're saying would work.

 

exactly.... have u ever tired disarming the alarm then seeing how long u could go without it arming again? pretty much anything u do electronically will arm the factory alarm. and while u can open the doors and put the key in to shut it up it will go off again until it is "disarmed"
