Ignition lock cylinder

So I am having a different problem that is getting fixed already but that problem is why my Eddie Bauer Edition Expedition has been parked for three weeks. Anyways my now ex tore the lock cylinder out because he had no key. AutoZone has one for $26.00 with the key. After looking at the picture, do you think that that is the only thing I will need to fix that part. Just install it or are there any other visible problems besides the covering gone because I have that still?
