if u take to private shop, most of them will say, you will lose key..
that is the fast way to do for them..and they might not have internet access handy..

with transponder bypass unit, download firmware into bypass unit..
bypass unit requires 2 keys to learn your chips and store the code..
whenever try to remote start, this bypass unit will fool the car that key is in..

most of cars only need 1 key to program..
but ford/mazdancoln needs 2 keys..
