On my Smartcode, the batteries drain within a few weeks.
Three possible issues: 1. The smart home system’s user interface falsely reports a low battery. If you receive an alert from your smart home system indicating that the battery is low, confirm this is true at the lock. Turn on switch #1 so that the status LED flashes every six seconds. If the LEDs turn amber or green, followed by a red flash, the battery is low. If the red flash is not seen, the battery is not low. This is an error on the smart home system side that will often be fixed when the lock is manually locked or unlocked. 2. The smart home system controller’s communication with the lock is draining the battery. Remove the lock from your system. Put a new set of batteries in the lock. Operate the lock in stand-alone mode for a week. If the batteries drain within the week, the problem resides in the lock. If the batteries do not drain, the problem may be the smart home controller. Call Technical Support. 3. The smart home system controller’s ping frequency is too high. Decrease the ping frequency from the controller to the lock to the lowest possible setting.
