The basic steps to reprogram your Schlage lock code
Most Schlage locks let you change the code yourself without calling a locksmith. The exact process depends on your model — keypad locks, deadbolts with keypads, and smart locks all work differently — but the general idea is the same: you enter a master code or use a reset sequence, then program your new code in.
The fastest way to find your specific model's instructions is to look at the lock itself. Schlage prints the model number on the back of the lock or on the interior side of the deadbolt. Write that number down and search for "[model number] how to change code" on Schlage's website or your lock's manual. The manual usually comes in the box; if you don't have it, you can read it from Schlage's support page using the model number.
If you've lost the master code or the lock is stuck, you'll need to reset it to factory settings, which erases all codes. That process also varies by model and sometimes requires removing the lock from the door.
Key Takeaways
- The steps to change a code differ between keypad entry locks, keypad deadbolts, and smart locks, so check your specific model number first.
- Most locks require you to enter the current master code before you can program a new user code.
- New codes are usually four to six digits, and the lock will beep or flash to confirm the code was saved.
- If you've forgotten the master code, you'll need to factory reset the lock, which erases all codes and may require removing the lock from the door.
How to change the code on a Schlage keypad deadbolt
Schlage keypad deadbolts — the kind where you punch numbers into a pad on the outside of the door — use a master code to control who can reprogram. If you know the master code, the process takes about two minutes.
Enter the master code, then press the Schlage button (usually a small button on the keypad or inside the door). The lock will beep once. Now enter the user code slot number you want to change — usually 1 through 6 — then press Schlage again. Enter your new four-to-six-digit code, press Schlage, and enter it again to confirm. The lock will beep twice to show the code was saved.
If the lock beeps three times or flashes red, the code didn't save. This usually means the code is too short, too long, or uses the same digit repeated (like 1111). Try a different combination and repeat the steps.
How to change the code on a Schlage smart lock
Schlage smart locks — models like the Encode or Connect — are reprogrammed through the Schlage Home app on your phone, not by entering codes at the lock itself. You don't need to know a master code.
Open the Schlage Home app, select your lock, and go to the Codes or Access section. You can add a new code, edit an existing one, or delete a code you no longer want. The app will show you which code slots are in use and which are empty. Enter the new code in the app, and the lock will update within a few seconds. You'll see a confirmation message when it's done.
If you don't have the app or can't access it, some Schlage smart locks have a backup keypad on the inside of the door that works like a traditional keypad lock. Check your manual to see if yours has this feature.
What to do if you don't know the master code
If you've inherited a lock, bought a used lock, or straightforward forgotten the master code, you'll need to reset the lock to factory settings. This erases all codes — both the master code and any user codes — and returns the lock to its original state.
The reset process varies widely by model. Some locks require you to hold down a small button on the interior side of the lock for 10 to 15 seconds. Others require you to remove the lock from the door and press a reset button on the back. A few models require you to enter a specific sequence of button presses.
Because the steps are so different, look up your exact model number and search for "[model number] factory reset" on Schlage's website. The manual will tell you whether you can reset the lock while it's installed or whether you need to remove it first. If you're not comfortable removing the lock, a locksmith can do it for you.
How to find your Schlage lock model number
The model number is usually printed on the back of the lock or on the interior side of the deadbolt. It's a series of letters and numbers, like FE595 or BE365. Take a photo of it or write it down.
Once you have the model number, go to Schlage's support website and search for it. You'll find the manual, which includes the exact steps for your lock, the master code (if it came with one), and the factory reset procedure. If Schlage's site doesn't have the manual, try searching "[model number] manual" on Google.
Common reasons a new code won't save
If you've entered a new code but the lock won't accept it, check these things first. The code may be too short or too long — most Schlage locks accept four to six digits, but some models have different limits. The code may also use a digit repeated too many times; some locks reject codes like 1111 or 2222.
The lock may also be in the wrong mode. If you didn't hear a beep after pressing the Schlage button, the lock didn't enter programming mode, and anything you typed after that was ignored. Start over and listen for the beep before you enter the new code.
If the lock beeps three times, that's a rejection signal. Try a different code and repeat the steps. If it keeps rejecting codes, the lock may need a battery replacement (if it's battery-powered) or a factory reset.
When to call a locksmith instead
If you've tried the factory reset and the lock still won't respond, or if the lock is physically damaged, a locksmith can replace the lock or reprogram it with specialized tools. This costs more than doing it yourself but is faster than ordering a new lock.
You should also call a locksmith if you need to remove the lock from the door to reset it and you're not comfortable doing that work. A locksmith can remove it, reset it, and reinstall it in under an hour.
Frequently Asked Questions
Can I change the code without knowing the master code?
No. You need the master code to reprogram user codes on a traditional Schlage keypad lock. If you don't have it, you'll need to factory reset the lock, which erases all codes. Smart locks are different — you reprogram them through the app, not with a master code.
How many codes can I program into a Schlage lock?
Most Schlage keypad locks have 6 to 19 code slots, depending on the model. Check your manual to see how many your lock supports. Smart locks usually have a higher limit — sometimes 100 or more — because they store codes in the app rather than in the lock's memory.
What happens if I forget my new code?
If you forget a user code, you can reprogram that slot with a new code using the master code. If you forget the master code, you'll need to factory reset the lock. Write down your codes and store them somewhere safe, like a password manager or a locked drawer.
Do I need to remove the lock from the door to change the code?
For most Schlage keypad locks, no — you can change the code while the lock is installed. For smart locks, you don't touch the lock at all; you change the code in the app. Some older models or factory resets may require removal, so check your manual first.
Will changing the code affect the physical key?
No. Changing the keypad code doesn't affect the key. If your Schlage lock has both a keypad and a key slot, both will continue to work after you change the code. The key and the code are separate entry methods.
