How to change your Schlage lock code

Most Schlage locks let you change the code yourself using the lock's keypad and a master code — you do not need a locksmith or a technician. The exact steps depend on which Schlage model you own: some use a straightforward four-digit code, others use six digits, and a few require you to enter a programming sequence first. If you have the original documentation or master code, you can usually finish the job in under five minutes.

If you do not have the master code, you will need to contact Schlage directly or call a locksmith, since there is no way to reset it yourself without it. The master code is usually printed in the original paperwork that came with the lock, or on a card inside the battery compartment on the back of the lock.

Key Takeaways

  • Most Schlage keypad locks change codes by entering your master code, then pressing the program button, then entering your new code twice.
  • The master code is usually printed in the original paperwork that came with the lock, or on a card inside the battery compartment.
  • If you have lost the master code, Schlage can look it up if you provide proof of ownership, but the process takes several days.
  • Different Schlage models (Encode, BE series, FE series) have slightly different button sequences, so check your model number before you start.
  • After you change the code, test it with the door unlocked to make sure it works before you lock yourself out.

Find your master code and model number

Before you change anything, locate your master code and confirm which Schlage model you own. The master code is usually a four- or six-digit number printed on a card that came with the lock when you bought it. Check the original packaging, the instruction manual, or any paperwork from the installer. If the lock was already installed when you moved in, ask the previous owner or the property manager.

If you cannot find the master code, look inside the battery compartment on the back of the lock. Some Schlage models print the master code on a label inside the battery door. You will also see the model number printed on the lock itself — it usually starts with letters like BE, FE, or Encode. Write down both the master code and the model number before you proceed.

If the master code is not printed anywhere and you do not have the original paperwork, contact Schlage customer service at 1-800-847-2522. Have your lock's serial number ready (also printed on the lock). Schlage can look up the master code if you can show proof that you own the property, but this usually takes three to five business days.

Change the code on a Schlage BE or FE series lock

The BE and FE series are the most common Schlage keypad locks in homes. To change the code, start with the door unlocked so you can test the new code before you leave. Press and hold the Schlage button (the small button on the back of the lock) for three seconds until you hear a beep. The lock will then prompt you to enter your master code on the keypad.

Enter your master code and press the Schlage button again. You will hear two beeps. Now enter your new four-digit code on the keypad and press the Schlage button. Enter the same code again and press the Schlage button a third time. You should hear two beeps to confirm the code has been saved. Lock the door and test your new code from the outside to make sure it works before you leave.

If you hear a red light or a buzzing sound instead of beeps, the code did not save. This usually means you entered the master code incorrectly or pressed the button at the wrong moment. Start over from the beginning and go slowly through each step.

Change the code on a Schlage Encode lock

The Schlage Encode is a smart lock that connects to your phone, but you can still change the code using the keypad alone. With the door unlocked, press and hold the Schlage button on the back of the lock for five seconds until the lock beeps and the light turns amber. Release the button.

Enter your master code on the keypad and press the Schlage button. The light will turn green. Now enter your new six-digit code and press the Schlage button. Enter the same code again and press the Schlage button once more. You should hear a beep and see a green light to confirm the change. Test the new code from outside before you close the door.

If you use the Schlage Home app on your phone, you can also change the code through the app instead of using the keypad. Open the app, go to the lock settings, and select "Change Code" from the menu. This method is often faster if you are already in the app and works from anywhere as long as your lock is connected to Wi-Fi.

What to do if the code does not work

If you enter your new code and the lock does not open, the code may not have saved correctly. Go back inside, unlock the door manually, and try the change process again. Make sure you are pressing the Schlage button at exactly the right moment — too early or too late will cause the lock to reject the sequence.

If you are certain you entered the code correctly but the lock still will not open, the batteries may be low. Replace the batteries (usually four AA batteries in the back compartment) and try again. A lock with weak batteries sometimes accepts a code during programming but fails to save it. After replacing the batteries, test your code again before assuming it did not save.

If the lock still will not respond after you have changed the batteries and tried the sequence twice, contact Schlage support or call a locksmith. Do not keep trying repeatedly, as some Schlage models lock you out temporarily after too many failed attempts.

Reset to the factory default code

If you have forgotten the code you set and you do not remember the master code either, you can reset the lock to its factory default code. This erases all codes and returns the lock to the state it was in when you first installed it. Press and hold the Schlage button for 10 seconds until you hear three beeps and see a red light. The lock is now reset.

The factory default code is usually 0-0-0-0 or 1-2-3-4, depending on the model. Check your original documentation to see which one applies to your lock. After you reset, you will need to reprogram the master code and set a new user code using the instructions above. Resetting the lock erases every code that was programmed into it, so make sure no one else is relying on their code to open the door before you do this.

Frequently Asked Questions

Can I change the code if I do not have the master code?

No, you cannot change the code without the master code. You will need to contact Schlage with proof of ownership, or hire a locksmith to reset the lock. Schlage can look up your master code if you provide the serial number and proof that you own the property, but this takes several days.

How many codes can I program into a Schlage lock?

Most Schlage BE and FE locks hold up to 19 user codes, plus the master code. The Schlage Encode can store up to 100 codes if you use the app. Each code must be four to six digits, depending on your model.

What happens if I forget my new code right after I change it?

If you are still inside the house, unlock the door manually and change the code again. If you are locked outside, you will need to call a locksmith or contact Schlage. This is why it is important to test the new code from outside while the door is still unlocked.

Do I need to change the code if I lose a key?

No. Schlage keypad locks do not use physical keys, so losing a key does not affect the lock. If someone else knows your code and you want to prevent them from entering, change the code and make sure they do not know the new one.

Can I change the code remotely using the Schlage app?

Yes, if you have a Schlage Encode lock and the Schlage Home app installed on your phone. You can change the code, add new codes, or delete old codes from anywhere. Other Schlage models require you to be at the lock to change the code using the keypad.
