car alarms

what car alarm system can i put in my car so that when i disarm the alarm my door locks open and my windows go down

well a dei alarm which are all the snake and bug brands. Say the Viper what was the 550 i think it's now the 560 (sorry we just got them as they are new for this year) but anyhoo. It just needs to have aux channels. Pending on how you want it to work. Either the windows go up when you lock/arm and down when you hit an aux channel which requires one type of module. If you want to be able hold a button and have it go up/down until you let go of the button which is a little more expensive. But there are some options clifford also does this. Now technically clifford is a dei company although they did keep some of the old egineers. The iq and g series had smart windows....

I 2nd all what 60hz163.5db said. Really though, I would probably go ahead with a window automation kit. It is much easier to install and gives you more options.
