I can't lock, or unlock vehicle with remote. The panic button on remote does nothing either. I changed batteries in both remotes, nether one works. Also,the power window, and door locks on passenger side are in-operative. I have checked what seemed to be ten thousand fuses, in three different locations, all are good, so where do I go from here? Please Help!!!!!!!

Same exact problem here. I had to replace the window actuator (???)($350) and get the remote reprogammed ($50)
