I had a Mopar Remote Car Starter installed on my 2007 Town & Country. Does any one know how to disconnect the horn from beeping when I start the car???

 

I just purchased a remote starter for my 09 caliber. After remote starting my car, i put the keys in the ignition and turn one click. When i put my foot on the brake to go into gear, my car turns off. Should this happen.

 

Turning the key "one click" may be putting it in the "off" position. There's an "off" position before the "on" position to allow for turning the steering wheel or moving the shift lever without having the engine on. You may be actually turning the engine off when you do that.
With the engine off, try turning the key carefully until the dash lights come on. That's the position you need to get to.
