Whatever you do, don't get the alarm system that the dealership installs
it is UGLY, & worthless, not to mention Over Priced.
The base system that comes with the Ram, won't let you start it without a electronic key
The alarm that the dealerships puts on, only seems to go off if you open the door, if you go through a window, you can strip the vehicle & pass all the goodies to a friend & climb back out through the window.
Of course anyone with much knowledge of any vehicle, can use a battery powered drill to drill up through the inner fender well & up into the battery, then they can pretty much do anything that they wish to, unless you also have a 2nd hidden battery
this is the dealership installed security system, just to the left of the hood release, GREEN round button on it, they call it the LUXURY model, the other one looks the same, it uses a round blue button
