Button
Inside Lock
When lock is reset to factory defaults, all user codes (including
the Master Passcode*) are deleted and all programming features
are reset to original default settings.
1. Remove the battery cover and batteries.
2. Remove the inside lock to access the reset button.
3. The reset button (see image at right) is located on left side of
PCB cable connector.
4. While pressing the reset button (minimum of 3 seconds)
reinstall batteries. Release reset button. Lock responds with
“Hi from Yale and Nest”.
5. Replace battery cover.
*The Master Passcode must be created before any other programming
of the lock either on the lock or through the Nest App.
Refer to pages 1 and 2.
NOTE TO INSTALLER AND CONSUMER
While Yale
®
has included several features to prevent lockout (9-Volt battery jumper, low battery warnings), it is still
possible for a lockout situation to occur. Because this product does not have a mechanical override (a key), Yale®
recommends to use this product in an environment where there are additional entry points into the dwelling.
