Thanks for visiting the Community. I’m sorry to hear that and for the delayed response. You have two options to change your pass code by performing a factory reset on your Nest x Yale lock or thru the Nest app.
Let me know how it goes.
Got it, thanks for your efforts here. Let’s have a better look — could you please factory reset your lock then let me know if that helps? Otherwise, we’ll be needing the help of Yale support to replace your Nest x Yale Lock as it may be defective.
