Maybe because the variable objectid is empty ?

and why does gatecheck even have a parameter?

Your problem was that you put objectid in SetTimerEx but in objectid was nothing saved
So you only need to put lspdg1 / lspdg2 instead of objectid in there

And here your code reworked since you checked for the area twice

forward gatecheck();
public gatecheck()
{
    for(new i; i != MAX_PLAYERS; i++) {
        if(!IsPlayerConnected(i)) continue;
        else if(PlayerFaction[i][police] == 1) {
            if(ObjectData[lspdg1][down] == 0) {
                if(IsPlayerInRangeOfPoint(i, 8.0, 1550.27575684, -1698.06298828, 27.36819077)) {
                    ObjectData[lspdg1][down] = true;
                    SetTimerEx("moveback",
                        MoveObject(lspdg1, 1550.27539062, -1698.06250000, 12.61819077, 1.00) + 2000,
                        false, "i", lspdg1);
                    continue;
                }
            }
            if(ObjectData[lspdg2][down] == 0) {
                if(IsPlayerInRangeOfPoint(i, 8.0, 1544.19995117, -1630.96655273, 12.38281250)) {
                    ObjectData[lspdg2][down] = true;
                    SetTimerEx("moveback",
                        MoveObject(lspdg2, 1544.17443848, -1623.71582031, 12.38281250, 2.00) + 2000,
                        false, "i", lspdg2);
                    continue;
                }
            }
        }
    }
}

And to the question why MoveObject is in SetTimerEx, MoveObject returns the time it will take for the object to move in milliseconds plus 2 seconds to stay opend
