This article provides instructions to factory reset the Nest x Yale Lock, YRD540.
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 (see below).
To perform a factory reset of your Nest x Yale Lock:
- Remove the battery cover and batteries.
- Remove the inside of lock to access the reset button.
- The reset button (see image) is located on the left side of the PCB cable connector.
- While pressing the reset button (for a minimum of 3 seconds), reinstall the batteries.
- Release the reset button. The lock should respond with “Hi from Yale and Nest”.
- Replace the battery cover.
Following a factory reset, Master PIN code creation is the only option available and must be performed prior to any other programming of the lock.
