Regarding electromechanical locks, is it true that the battery must be changed frequently?

• A. The battery must be changed frequently.
• B. The battery does not need to be changed frequently.
• C. Only during maintenance.
• D. The battery is replaced when the lock stops working.

Answer: (B)

Power management in electromechanical locks is designed so the unit spends most of its time in a low-power state and only draws significant current when the bolt moves or it communicates with access control. Because of that, the battery life tends to be long, and changes are not needed frequently. The exact interval depends on battery type and how often the lock is used, but many models last months to a couple of years between replacements, with a low-battery alert to warn you before it dies. Some locks can be powered by an external supply or use rechargeable packs, which can further reduce how often you replace batteries. So, the idea that you must change the battery frequently isn’t accurate in typical operation; you replace it as needed when the low-battery indicator signals or as part of routine maintenance, not on a fixed frequent schedule.
