you get vehicle model !!
but you need to get vehciel id !

try this:

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(newkeys == KEY_NO)
    {
        if (IsPlayerInAnyVehicle(playerid))
        {
                new vehicleid = GetPlayerVehicleID(playerid); //~~~~>this line was your problem i changed "GetVehicleModel" with GetPlayerVehicleID
                new engine, lights, alarm, doors, bonnet, boot, objective;
                GetVehicleParamsEx(vehicleid, engine, lights, alarm, doors, bonnet, boot, objective);
                SetVehicleParamsEx(vehicleid, 1, lights, alarm, doors, bonnet, boot, objective);
        }
    }
    return 1;
}
