"Screwdriver" attacks on door locks

[Rebaseonu]

Hey,

I'm thinking about buying a 6 barrel door lock set for Defender 90, so I have some spare lock barrels that use the same key in case some of them will be cracked. However, when this kind of attack occurs, maybe there will be more damage inside the locking mechanism than just ruined barrel? That means even I have new barrel, I still can't fix it, so taking barrels is useless.

Any advice? I just don't want to take too much stuff (spare door ), but a few lock barrels sound like a good idea.

Thanks!
