First exchange lock and unlock relays (see Owner's manual). The two identical relays are in the fuse box at the end of the driver's side of the dash - they have the exact same model number. Once you exchange their places, try your fob and see if the problem has reversed itself. If so, you have a bad relay and need to replace it. Consider replacing both of them while you are at it.
Second, contacts on inside of fob - the unlock side - may be dirty. Try cleaning them and see what happens.
