You probably want to know how to reset the master code of your Nest Yale lock because you forgot it. If not, maybe someone knows your hidden master passcode. Whatever the reasons, changing the Nest Yale master passcode is not as easy like other smart deadbolt locks‘ passcode.
If you have no reason, nevertheless, you should change the master passcode frequently. I highly recommend changing it every 2 or 3 months. You have to complete the entire process by resetting your Yale lock first.
However, if you lose the Nest Yale lock’s instruction manual book, the resetting process will be very tough for you. Don’t worry; here I’ll guide you step by step to reset the lock and change the master passcode to the new one.
If you are new to Google-powered Nest Yale locks and don’t know much about the master passcode of the lock, below is the section for you.
What is Master Passcode of Nest Yale Lock?
A master password is a code that you need every time you change the master function or setting in your Nest Yale Lock. If you want to change any settings on your Nest Yale Lock, you have to enter the master passcode each time.
The default passcode of your Nest Yale lock is 123456. But you can change the default code to a new custom code during the first installation. If you ever forget your custom new passcode, you have to reset the lock to its factory settings.
If you are connected to the Nest app, you can add, remove, or change the master passcode from the app. You can also use the Nest App to add user passcodes for anyone who needs access to your home.
So using the Nest app to control everything is super convenient and easy.

- From the Passcodes setting section, tap on “You” to change the master code.

Reset the Master Code of Nest Yale Smart Lock
Somehow, if you forget the master code of a Yale lock and you never remember, you have to reset the lock to get it back. Resting any device brings it back to the default functions and settings that it had before.
I hope the following step-by-step guide will help you to reset your Nest Yale lock easily.
Step #1: Take the key of your Nest Yale lock in your hand. If you somehow lost the key, you can buy a thumbtack (it’s one kind of pin with a flat board) that you can use to remove the battery cover.
Step #2: To open the battery cover, press the battery cover key or insert your thumbtack into the cover lock battery compartment hole and pull up. Then remove all batteries from the compartment and store these near you for quick access.
Step #3: With a standard screwdriver (you can use a Phillips head screwdriver), unscrew 2 bolts from the mounting plate of the lock.
Step #4: On the lock’s back left side, hold down the RESET button of the lock’s cable connector. At the same time, insert all batteries into the battery compartment. Hold the reset button until the red light turns on. If you see a red light, release the reset button.
Step #5: Press the power button of your Nest Yale lock, and you will soon hear the welcome sound, ‘Hi, I’m Yale and Nest.
Step #6: Now, screw the two bolts on the mounting plate (back part).
Step #7: Replace the old battery with new or you can use the existing batteries (if these are in good condition). Then insert the compartment cover and lock it.
