What to do
- Use a firearm when you reach the rusted lock.
- Aim at the lock itself rather than treating the surrounding door as the target.
- Shoot the lock. Do not use a failed melee hit as proof that the lock cannot be opened.
Why it feels stuck
The game’s feedback can make a rusted lock appear impervious when you test it with melee attacks. The evidence-backed fix is narrower: shoot the lock with a firearm. This guide does not claim that the same interaction applies to every locked door.
