I have half doors that I use during the summer and part of fall and spring and I do not have any power features. I don't think there is a point to the power features.
I leave my doors unlocked all the time and most of the time, I do not even have my door uppers on.
The only thing I do, is I will arm the jeep with the remote. This way, if the door is opened without disarming, the alarm will sound. That's good enough for me
