stl map error error C2440

hey all,
I am attempting to use map with VC 2005. where i need to map one
integer value to another integer
for e.g 2:5
4:5
the actual use is to map a common int value with direct input values.

here is the code

SN_Input.cpp

//initializes the map
void SN_Input::init_keymap(){
    //vector
    vector<int>* vec=new vector<int>;
    vec->push_back(KEYBOARD_PARAM::LEFT_ARROW);
    vec->push_back(DIK_LEFT);

    keyMap=new map<int,int>();
    keyMap->insert(vec->begin(),vec->end());
}

// function to see if a key is pressed or not, called from a different
file game.cpp
bool SN_Input::isKeyPressed(int key){
int value=keyMap[KEYBOARD_PARAM::LEFT_ARROW];
if(fDIKeyboardState[value] & 0x80){
        return TRUE;
    }
    return FALSE;
}

it gives me the following error:
1>c:\users\suja\documents\visual studio 2005\projects\sujatha-ase-
project\sujatha-ase-project\sn_input.cpp(197) : error C2440:
'initializing' : cannot convert from 'std::map<_Kty,_Ty>' to 'int *'
1> with
1> [
1> _Kty=int,
1> _Ty=int
1> ]
1> No user-defined-conversion operator available that can
perform this conversion, or the operator cannot be called

can anyone please tell me how to correct this error?
i googled but not much info avail.
