Almost Positive there's no factory command start in 05 and i'm prety sure not in 06 either.
You can get mopar one now , and feel free to correct me, but from what i've heard they're crap . they have the same range as the lock/unlock feature so they are useless unless your jeep happens to be in the attached garage next to you . go aftermarket and get at least a 1500 ft range so you can at least start your car from the wally world entrance .
