For those of you who don't remeber I bought the auto door locking unit from Coastal tech a few weeks ago. It came in quickly, but it didn't work. After a long and arduous process of no support and e-mail returns I finally talked to somone who helped. To their credit, Coastal tech sent me a new unit without question, and as far as I can tell, without charge. We put it in today and at first we thought it didn't work. I am under the impression that they are supposed to lock the doors when you reach 15 mph. Ours didn't. But later, we realized that when we get in the car and close all the doors before powering on, the unit auto locks the doors. Is this supposed to happen? As a side note, if we power on and have any of the doors open, then the unit will not lock, which is a good thing because you won't lock yourself out. Anyway, is this normal, or am I still in Coastal tech hell?
