Changing your Schlage lock code yourself takes five to ten minutes and requires only the master code and the lock's keypad
Most Schlage locks let you change the user code without calling a locksmith or removing the lock from your door. The exact steps depend on whether you have a keypad lock (the kind you punch numbers into) or a smart lock (controlled by an app or keypad). If you still have the original master code that came with the lock, you can reset the code right now. If you have lost the master code, you will need to contact Schlage or hire a locksmith to reset the lock to factory settings.
The process is the same whether you are changing a code because someone moved out, you forgot the combination, or you want to update it for security. You do not need any tools beyond your fingers.
Key Takeaways
- You need the master code to change a user code on a Schlage lock; without it, you will have to contact Schlage support or hire a locksmith.
- Keypad locks and smart locks use different methods to change codes, so check your lock type before you start.
- New codes must be at least four digits and cannot be the same as your master code or any other active code on the lock.
- After you enter the new code, test it from outside the door before you rely on it, because some locks require you to lock and unlock the door first.
How to change the code on a Schlage keypad lock
If your lock has physical buttons you press to enter numbers, follow these steps. First, enter your master code and press the Schlage button (the button with the Schlage logo). The lock will beep once and the light will turn green. You now have 30 seconds to proceed.
Press the button labeled with a house or home symbol, or the button marked "1" if there is no symbol. The lock will beep twice. Now enter the user code slot number you want to change — usually "1" for the first code slot. The lock will beep once. Enter your new four-digit code, then press the Schlage button again. The lock will beep three times and the light will turn green, which means the code has been saved.
Exit the programming mode by pressing any button or waiting 30 seconds. Test the new code from outside the door by locking it manually, then unlocking it with the new code. Some Schlage locks require you to cycle the lock (lock and unlock it) once before a new code becomes active.
How to change the code on a Schlage smart lock
Smart locks like the Schlage Encode or Schlage Connect use an app or a keypad to manage codes. Open the Schlage Home app on your phone and sign in with your account. Tap the lock you want to change, then select "Access Codes" or "Manage Codes" depending on your model.
Tap the code slot you want to change or add a new code. Enter the new four-digit code in the app and confirm it. The app will send the new code to the lock over Wi-Fi or Bluetooth, usually within a few seconds. You will see a confirmation message when the code has been saved. Test the new code on the keypad or by unlocking the door with the app to make sure it works.
If your smart lock has a physical keypad on the door itself, you can also change codes directly on the keypad using the same master code method as a standard keypad lock. Check your lock's manual to see whether your model supports this.
What to do if you do not have the master code
If you have lost or do not know the master code, you cannot change the user codes without resetting the lock to factory settings. Contact Schlage customer support at 1-800-847-2522 with proof of ownership (receipt, photo of the lock, or registration information). They can walk you through a reset process or direct you to an authorized dealer.
Alternatively, you can hire a locksmith to reset the lock. This usually costs between $75 and $150 depending on your area and the lock model. The locksmith will remove the lock, reset it, and reinstall it, or they may be able to reset it in place if they have the right tools.
If the lock is in a rental property or you are locked out and cannot wait, contact your landlord or property manager. They may have the master code or be able to authorize a locksmith to reset it.
Rules for creating a new Schlage lock code
Your new code must be at least four digits long and no more than eight digits, depending on your lock model. Check your manual for the maximum length. The code cannot be the same as your master code, and it cannot match any other active code already on the lock.
Avoid codes that are straightforward to guess, like "1234" or "0000", or sequences based on your address, birthday, or phone number. If multiple people use the lock, use different codes for each person so you can see who unlocked the door and when (on smart locks with activity logs).
Some Schlage locks let you store up to 19 different user codes, so you can assign one to each household member, contractor, or guest. Each code can be set to work all the time or only during certain hours or days of the week.
Testing your new code before you need it
After you program a new code, lock the door manually from the inside and step outside. Enter the new code on the keypad and listen for the beep and light. The lock should click open. If it does not, go back inside and check that you entered the code correctly during programming.
If the lock still does not respond, try cycling it again — lock and unlock the door manually from the inside, then test the code from outside. Some Schlage models need this extra step before a new code becomes active. If the code still does not work after cycling, delete it and program it again, making sure you press the Schlage button firmly and wait for the correct number of beeps at each step.
Deleting an old code or revoking access
To remove a code from your lock, enter your master code and press the Schlage button. Press the home or "1" button, then enter the code slot number you want to delete. Press the Schlage button three times in a row. The lock will beep four times and the light will turn red, which means that code slot is now empty.
On a smart lock, open the Schlage Home app, tap the lock, select "Access Codes", and tap the code you want to remove. Choose "Delete" and confirm. The code will stop working when ready. This is useful if a contractor, guest, or household member no longer needs access.
Frequently Asked Questions
Can I change my Schlage code if I am locked out?
No — you need to be able to reach the keypad or have the app connected to change a code. If you are locked out, call a locksmith or contact Schlage support. If it is a smart lock, you may be able to unlock it remotely through the app if you still have access to your account.
What happens if I forget my new code right after I set it?
You can change it again using the same master code process. If you forget the master code, you will need to reset the lock. Write down your new code and store it somewhere safe, or use the smart lock app to store it securely.
Do I need to tell Schlage when I change my code?
No. Changing your code is a local operation on the lock itself. Schlage does not track or need to know about code changes. On a smart lock, the app syncs the change to your account, but Schlage support cannot see your actual code.
Can two people have the same code on my Schlage lock?
Technically yes, but it is not recommended. If you assign the same code to two different code slots, the lock will not be able to tell which person unlocked it. Use separate codes for each person so your activity log shows who entered the door and when.
How often should I change my Schlage lock code?
Change it whenever someone moves out, a contractor or service person no longer needs access, or you suspect someone knows the code. For security, consider changing it every six months to a year if many people have used the lock. Smart locks make this easier because you can delete old codes remotely.
