Recover Access to Your Own Locked Container
Use the Locksmith Recovery System
If your server has the locksmith recovery mechanic enabled and you've lost your key, you can pay a fee to unlock your own container. This is a safety net for accidental key loss, but it costs resources.
Request Recovery
Right-click your locked container and select the recovery option if available. The server will prompt you to confirm the payment. Once paid, the container unlocks and you regain access.
Alternative: Pick Your Own Lock
If recovery isn't available or you prefer not to pay, craft lockpicks and solve the minigame yourself. You'll take damage on failure, but there's no cost. This method requires patience and multiple picks.
Prevent Future Lockouts
Always keep your renamed key in a safe, accessible location. Consider storing a backup key in a separate secure container or with a trusted friend. Write down your key names if you have many containers.
