All major Chrysler brands (Dodge, Jeep, RAM and more) have the same ignition system. Old Chrysler ignitions operate like a typical lock mechanism by sliding the key into the ignition you are compressing the pins to line up on the sheer line according to the key pattern. Then as you wish to turn the ignition, the “side bar” needs to be pressed as well. This sidebar is similar to many US ignitions including GM.
