The pictures shows the wrong key
The pictures shows the wrong barrel
The discriptions right
Might just have the wrong pictures, anyone's guess
Even with the right key and barrel it does not end there
And how you go about it will vary according to which keys you normally use,
Remote if you get a new key blade cut and fitted you will be able to open the car with the remote and start it, you will have to carry an original as well incase say the button on the remote or battery fails
If you only use the manual key, you will have to carry both keys one for the door one for the ignition, then you have two options, one get the key programed , I can't see in the ebay listing if there is a blank transponder fitted or not or two cut both keys open and swap the transponder chip over, some third party keys clip together, easy job, some are glued together, not for the faint hearted
Personly if I had to change the ignition I would change as a set boot and door so I only had to carry one key
