One of the most common (and costly) issues we see with electronic locks is the use of the wrong 9V battery. Not all batteries are created equal. Cheap or off-brand batteries often don’t provide enough consistent power to fully disengage the lock mechanism, while lithium batteries can deliver too much voltage and potentially damage the motherboard. To ensure reliable performance and avoid unnecessary service calls, always use high-quality alkaline batteries such as Duracell, Energizer, or Procell. Using the correct battery can save you both time and money since many service visits turn out to be nothing more than a simple battery issue.
