Fuel cap lock

Can the barrel be changed on a fuel cap?

Have a feeling it can because the same key that opens the door opens the cap - look on the inside - if theres a retaining c clip in the middle then it can probably be swapped (sorry my novas original fuel cap is long gone otherwise I'd check). The issue is whether you can get a replacement barrel...

Managed to get as far as taking the spring off and the little catches but couldn't figure out how the barrel comes out. As want to swap it with my other car so it has a proper fuel cap again
