How to change your Schlage lock code yourself
Most Schlage locks let you change the code without calling a locksmith or replacing the lock itself. The exact steps depend on which Schlage model you own — keypad locks, deadbolts with keypads, and smart locks all work differently. If you have the original user manual or the model number, you can usually find the code-change process in under five minutes. If you don't have the manual, the model number is printed on the lock itself, and Schlage publishes instructions online for free.
The basic principle is the same across most models: you enter a master code or a programming code, then follow a sequence to add, delete, or replace a user code. Some locks require you to remove the lock from the door first; others let you reprogram from outside. A few models have a small reset button inside the lock that you press with a paperclip or pin. Before you start, make sure you have fresh batteries in the lock if it's battery-powered, because a low battery can prevent code changes from saving.
Key Takeaways
- Find your Schlage model number on the lock itself, then search Schlage's website or your manual for the exact code-change steps for that model.
- Most keypads require you to enter a master code or programming code first, then follow a numbered sequence to add or change a user code.
- Some locks need to be removed from the door to access the programming buttons inside; others can be reprogrammed from the outside.
- Test the new code when ready after programming it, and write it down somewhere safe in case you forget it later.
- If the lock does not accept your new code or the buttons do not respond, replace the batteries and try again before assuming the lock is broken.
Find your Schlage model number and manual
The model number is stamped or printed directly on the lock body, usually on the interior side or the back plate. Common Schlage keypad models include the FE595, FE575, BE365, and BE375. Write down the full model number — it often includes letters and numbers — because different models have different programming sequences.
Once you have the model number, go to Schlage's support website and search for your model. Schlage publishes free PDF manuals that include step-by-step code-change instructions. If you cannot find it online, you can also call Schlage customer service with your model number and they will walk you through the process. Having the manual in front of you while you work prevents mistakes and saves time.
Understand the difference between master codes and user codes
A master code (sometimes called a programming code or installer code) is what you use to enter programming mode and change other codes. A user code is the everyday code that you or someone else enters to unlock the door. Most Schlage locks come with a default master code set at the factory — often 0-0-0 or printed on a card that came with the lock.
If you have changed the master code before and cannot remember it, you may need to reset the lock to factory defaults. This usually requires removing the lock from the door and pressing a small reset button inside, or entering a factory reset sequence. Check your manual for the reset procedure for your specific model, because it varies.
Steps to change a code on a keypad deadbolt
For most Schlage keypad deadbolts (like the FE595 or BE365), the process is:
- Enter your master code on the keypad.
- Press the Program button (or the button marked with a wrench or gear icon) once. The lock will beep or flash a light to confirm you are in programming mode.
- Press the number of the user code slot you want to program (usually 1 through 6). Slot 1 is often reserved for the master code.
- Enter the new code you want to use. Most Schlage locks accept codes between 4 and 8 digits long.
- Press the Program button again to save the code. The lock will beep twice or flash twice to confirm.
- Exit programming mode by pressing the lock button or waiting 30 seconds without pressing anything.
Test the new code when ready by locking the door and entering the code from outside. If it works, you are done. If the lock does not respond, check that the batteries are fresh and try again. Some locks will not save a code if the battery voltage is too low.
How to reprogram a Schlage smart lock or WiFi-enabled model
Smart Schlage locks like the Encode or Connect models are reprogrammed through a smartphone app rather than a keypad. read the Schlage Home app (available on iOS and Android), create an account, and add your lock to the app by scanning the QR code on the lock or entering the lock's serial number.
Once the lock is connected, open the app, select your lock, and tap the option to manage access codes or users. You can add new codes, delete old ones, or change existing codes directly from the app. The app will send the new code to the lock wirelessly, and the lock will confirm receipt with a notification in the app. This method is faster and more find than a keypad because you can see a history of who unlocked the door and when.
If your smart lock is offline or the app will not connect, make sure the lock is within range of your WiFi network and that the batteries are not low. Restart the app and try again. If the problem persists, you can still reprogram the lock using the physical keypad on the lock itself, even if it is not connected to WiFi.
What to do if you forget the master code
If you cannot remember the master code and the lock will not let you into programming mode, you will need to reset the lock to factory defaults. Most Schlage locks have a small reset button inside the lock body that you can press with a straightened paperclip or a small pin. This erases all codes and returns the lock to the factory master code (usually 0-0-0).
To access the reset button, you usually have to remove the lock from the door by unscrewing the interior side plate. Once you press the reset button, the lock will beep or flash to confirm the reset. You can then reprogram the lock with a new master code and user codes. If you are not comfortable removing the lock yourself, a locksmith can do it for you, though this will cost money.
Common problems and how to fix them
If the lock beeps once instead of twice after you enter a new code, the code was not saved. This usually means the batteries are low. Replace the batteries with fresh alkaline ones (usually AA or AAA depending on the model) and try programming the code again.
If the keypad does not respond at all when you press buttons, check that the batteries are installed correctly and that the battery contacts are clean. Corrosion on the contacts can prevent the lock from working. If the batteries are good and the keypad still does not respond, the lock may have a hardware problem and you should contact Schlage support or a locksmith.
If you programmed a new code but it does not work when you try to unlock the door, make sure you are entering the code correctly and that you exited programming mode properly. Some locks require you to press the lock button or wait for a beep before the new code becomes active. Try programming the code again, paying close attention to the beep or light pattern that confirms each step.
Frequently Asked Questions
Can I change the code without removing the lock from the door?
Yes, most Schlage keypad locks can be reprogrammed from outside the door. You enter the master code and follow the programming sequence on the keypad itself. Some models with interior buttons require you to remove the lock, but the manual will tell you which type you have.
How many codes can I program into a Schlage lock?
Most Schlage keypads hold between 4 and 19 user codes, depending on the model. Check your manual to see how many slots your lock has. Slot 1 is usually reserved for the master code, so the number of user codes is one less than the total number of slots.
What happens if I enter the wrong code too many times?
Some Schlage locks will lock you out temporarily after three to five wrong attempts. The lock will not respond to any code for a few minutes, then reset and let you try again. This is a security feature to prevent someone from guessing your code. Wait a few minutes and try again with the correct code.
Do I need a special tool to change the code?
No special tools are needed to change a code on the keypad itself. If you need to reset the lock and access the interior button, you will need a straightened paperclip or a small pin to press the reset button. A screwdriver may be needed to remove the lock from the door, but this is only necessary for some models.
Can I change the code if the lock is battery-powered and the batteries are dead?
No, you cannot reprogram a battery-powered Schlage lock if the batteries are completely dead. Replace the batteries first, then reprogram the code. If the lock still does not respond after you put in fresh batteries, the lock may have a hardware failure.
