Which of the following must you do when opening an electromechanical lock such as the X-07, X-08, X-09, and X-10?

• A. Turn the dial and stop it when you see the correct number displayed on the LCD.
• B. Use a standard key
• C. Force the lock open
• D. Enter a master code only

Answer: (A)

The key idea is that these electromechanical locks rely on input via a dial and a guiding display. When you rotate the dial, the lock’s electronics show the current number on the LCD, and you must stop at the exact number that forms the correct combination. This alignment proves you’ve entered the intended sequence, allowing the internal mechanism to disengage and open. Using a standard key won’t work because this type of lock isn’t opened by a key blade, and forcing the lock is unsafe and ill-advised. While some systems may support a master code, the required action described here is the dial input guided by the LCD to reach the correct numbers in order. So the essential step is to turn the dial and stop at the correct number displayed on the LCD.
