Keys stopped working, changed large thing in fuse box (forgive me, I'm a lady), changed batteries, got new keys, resynchronized, nothing works. After taking to dealer twice, they offered me a user car so they could "dig" into it further...ummm, I chose to live without them digging into my pockets! lol...doesn't anyone know how to overcome this? Fix it? Do I get a new remote key system? Anybody have this problem before? I have to constantly hit the lock button from inside, then close my door and use the key to lock it....if I lock the doors from the passenger side, it locks the drivers door!...really crazy...and also, my gas tank never gets locked...any suggestions?
