This is just an example of how I do it. Of course you would fill in everything with your server information. This is untested.

new IsGateOpen = 0;
public OnPlayerKeyStateChange(playerid ,newkeys, oldkeys)
{
    if(newkeys == KEY_FIRE)
    {
        if(IsPlayerInRangeOfPoint(playerid,x,y,z)) //gate coordinates go here.
        {
            if(GetPlayerMoney(playerid) > 100) //Checks if player has 100 at least.
            {
                GivePlayerMoney(playerid, -100); //This takes away 100 dollars from the player who opens the gate.
                BizzMoney = BizzMoney + 100 //Don't use this variable. Just an example. But this gives the business the money.
                if(IsGateOpen == 0)
                {
                    MoveObject(objectid,x,y,z)//Moves Object
                    IsGateOpen = 1;
                {
                else if(IsGateOpen == 1)
                {
                    MoveObject(objectid,x,y,z)//Moves Object back to original position.
                    IsGateOpen = 0;
                    return 1;
                }
            else if(GetPlayerMoney(playerid) < 100)
            {
                SendClientMessage(playerid,COLOR_GREY,"You do not have enough money to pay the toll.");
                return 1;
