• Specialized Lishi-style tools included for mechanical hotel locks, enabling authorized staff to decode locks when guest keys are lost or to audit lock functionality without compromising mechanical security.

• Innovative design transforms user interaction from external manipulation to internal communication, enabling the lock itself to reveal its combination through tactile feedback and visual indicators.

• When encountering confusion or suspected errors during operation, the standard corrective procedure involves fully releasing tension to reset the lock, then restarting the decoding sequence from the beginning for optimal results.
