I think i got the solution, at the radi of each GetDistanceBetweenPlayerobj to 1 instead of 15, because 15 is too big..

for example; like that

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
  if((newkeys == KEY_HORN) && (IsPlayerInAnyVehicle(playerid))){
    if(GetDistanceBetweenPlayerobj(playerid,1234.5, 1234.5, 1234.5) < 1){ // WHERE TO BE SO IT CAN BE OPENED
      MoveObject(gate1,xxxxx, xxxxxx, xxxxx);
      SendClientMessage(playerid, COLOR_RED, "You've opened the Gate.");
      return 1;
    } 
    if(GetDistanceBetweenPlayerobj(playerid,6789.10, 6789.10, 9789.10) < 1){ // WHERE TO BE SO IT CAN BE CLOSED
      MoveObject(gate1,xxxxx,xxxxx,xxxxx);
      SendClientMessage(playerid, COLOR_RED, "You've closed the Gate.");
      return 1;
    }
  } return 0;
}
