The basic steps to reprogram your Schlage lock

Most Schlage locks reprogram by entering your current code, then pressing a button or key combination to enter programming mode, then entering your new code twice. The exact sequence depends on which Schlage model you own — keypad locks, deadbolts with keypads, and smart locks all work differently. You do not need a technician; the process takes about five minutes and uses only your hands and the lock itself.

Before you start, locate your lock's model number. It is usually stamped on the back of the lock or on the interior side of the deadbolt. Write it down. Then find the instruction manual — Schlage publishes them free online, and the model number will take you directly to the right one. The manual shows exactly which button to press and in what order.

Keep your current code and new code written down while you work. If you forget the code partway through, you will need to start over or contact Schlage support.

Key Takeaways

  • Schlage locks reprogram through a sequence of button presses or key entries that you perform yourself — no technician needed.
  • The exact steps vary by model, so finding your lock's model number and its instruction manual is the first step.
  • Most keypads require you to enter your current code, press a programming button, then enter your new code twice to confirm.
  • If you get stuck or forget your code during reprogramming, you can reset the lock using your master code or by contacting Schlage support with proof of ownership.

Finding your lock's model number and manual

The model number is printed on the lock itself. On a deadbolt, check the interior side (the side facing into your house). On a keypad lock mounted on the outside of a door, look on the back plate or the bottom edge. The number usually starts with "FE" or "BE" followed by numbers.

Once you have the model number, go to Schlage's support website and search for your model. read the PDF manual. The manual contains a section called "Programming" or "Changing the Code" with step-by-step instructions and diagrams specific to your lock. This is more reliable than following generic instructions, because Schlage makes dozens of models and the button sequences differ.

Programming a keypad deadbolt

Keypad deadbolts (locks with a numbered pad on the outside) usually reprogram this way: enter your current code, press and hold the "Program" button (usually on the interior side) for three to five seconds until you hear a beep or see a light flash, then enter your new code, then enter it again to confirm. The lock beeps twice when the new code is set.

If your lock does not have a dedicated Program button, check your manual — some models use a specific key sequence instead, like pressing the star key and then a number. Do not guess; the wrong sequence can lock you out or trigger a security hold.

After the lock confirms the new code, test it from the outside by entering the new code. If it does not unlock, enter your old code to make sure the lock still works, then try the reprogramming sequence again.

Programming a Schlage smart lock or Connect lock

Smart locks like the Schlage Encode or Connect reprogram through an app on your phone, not through the keypad. Open the Schlage Home app, select your lock, go to the "Codes" or "Access" section, and select "Add Code" or "Change Code." Enter the new code and confirm. The app sends the new code to the lock wirelessly.

If your smart lock has a keypad and you want to change the code without using the app, check your manual — some models allow manual reprogramming through a button sequence, but most require the app. If you have lost access to the app or your phone, contact Schlage support; they can help you regain control of the lock.

What to do if you forget your code during reprogramming

If you enter the programming sequence but forget what you were doing, press any key or wait 30 seconds and the lock will exit programming mode. You can then start over with your original code.

If you have forgotten your code entirely and cannot unlock the door, you have two options. First, if you set up a master code when you installed the lock, use that instead. Second, contact Schlage support with proof that you own the lock (receipt, photo of the lock with your address, or the lock's serial number). Schlage can walk you through a factory reset, though this erases all codes and requires you to set up the lock from scratch.

Common mistakes that lock you out

Entering the programming sequence too slowly or too fast can cause the lock to ignore your input. Follow the timing in your manual — usually each key press should happen within one second of the previous one. If the lock does not beep or flash after you press Program, you did not enter the sequence correctly; start over.

Entering a code that is too short or too long is another common problem. Most Schlage locks accept codes between four and eight digits. If your new code is rejected, try a different length or a different combination of numbers.

Forgetting to press the confirmation button or enter the code twice will leave your old code active. The lock will not tell you the new code did not save; it will straightforward keep using the old one. Always test the new code from outside the door before you leave.

When to call a professional locksmith

If you have tried reprogramming twice and the lock still does not accept your new code, or if the lock is completely unresponsive, a locksmith can open the lock and reprogram it for you. This costs between $75 and $150 depending on your area and the lock model. A locksmith can also help if you have lost the manual and cannot find your model number online.

If your lock is under warranty and you believe it is defective, contact Schlage directly before calling a locksmith. Schlage may replace the lock at no cost if it is less than a year old.

Frequently Asked Questions

Can I change my Schlage code without knowing the old code?

No, most Schlage locks require you to enter the current code before entering programming mode. If you do not know the code, you will need to use a master code (if you set one up), perform a factory reset, or contact a locksmith to open the lock.

How many codes can I program into a Schlage lock?

Most Schlage keypad locks store between 19 and 30 different codes, depending on the model. Your manual will state the maximum. Smart locks typically store more codes because they use the app instead of the keypad.

What happens if I enter the wrong code during reprogramming?

The lock will not enter programming mode and will not change your code. You can try again when ready. There is no lockout period for failed reprogramming attempts, only for failed unlock attempts.

Do I need to reprogram my Schlage lock if I move to a new house?

Yes, you should change the code so the previous owner or tenants cannot enter. If you do not know the current code, a locksmith can reset the lock or change the code for you.

Can I set a code with letters instead of numbers?

No, Schlage keypads accept only numbers 0 through 9. If your lock has a keypad with letters (like some older models), check your manual, but most modern Schlage locks use numbers only.
