New ignition lock cylinder

Two questions actually. I was sent a replacement ignition lock cylinder and it's exactly the same as the one I'm replacing except for one thing. There's something connected to the one I'm replacing it's in white plastic casing looks like a fuse or relay with a pin that has two springs in it that's sits in the ignition.
Well, the new one doesn't have the cut out where the pin sits if I were to take it off and put it on the new one everything else is the same. There's a positive and negative wire that is connected right behind where you put the key in and it leads to this part that the new one doesn't have
Do I need to send the part back or will it work without it?
The car turns over but I have to get a key programmer ob2 tool or have a locksmith come program the key but it's not going to work anyways because of the part that's not on the new one I need to send it back.
