Ignition barrel jammed

[Callum 13 1 Cars]

Drove my car to work today to do some work on it then I went to start it once done and the key wouldn't go all the way into the ignition barrel, tried lubricant and tapping the barrel with a small hammer but nothing, I'm going to try my spare key tomorrow but anyone have any ideas?  Worth mentioning I have never touched the barrel and I wasn't doing anything near it previously today

Happened to me once with a brand new Valeo barrel. Had to destroy it to get it out of the way in the end. Key got stuck inside it and could not get it out.

No good tips on this  matter from me sadly.

I read about that in a previous post going to try my spare key before I destroy the barrel
