Replacing batteries
When replacing batteries, the memory is not lost, but the time setting is lost after two minutes. The Keypad EZ Lock has a warning system to let you know when the batteries are getting low. At the first sign of warning, although you have some time to replace the batteries before they fail, you need to replace the battery pack or batteries as soon as possible.
