I have a 2007 and the only way the keyless remote will work on the car is if you are standing next to it. If you take a couple of steps away it's worthless. To open the truck while at the back of the car you have to wave it around till the trunk pops. I replaced the battery in the fob and eventually bought a new one from the dealer, but still have the same problem. Remote start is worthless if you have to stand by the car in the hot or cold to activate it!! lol! Any suggestions?
