Replace the Keypad Battery

When the keypad battery is expired, the date and time go back to the default settings. Use this procedure to replace the battery.

To replace the battery, use a Hitachi Maxell “CR2016 Lithium Manganese Dioxide Lithium Battery” or an equivalent battery with these properties:

  • Nominal voltage: 3 V

  • Operating temperature range: -20°C to +85°C (-4°F to +185°F)

The performance life estimate of a new battery is different for different keypad versions.

Refer to “REV” on the keypad nameplate for the keypad version.

  • Keypad with REV: H and earlier or REV: J and later

    • 5 years (20 °C (68 °F))

    • 3.5 years (-10 °C to +50 °C (14 °F to 122 °F))

  • Keypad with REV: I

    • 2.5 years (20 °C (68 °F))

    • 1.8 years (-10 °C to +50 °C (14 °F to 122 °F))
