Changing a Schlage combination requires the current code, a screwdriver, and about five minutes
Most Schlage locks let you change the combination yourself without calling a locksmith. The exact steps depend on which Schlage model you own — keypad locks, dial locks, and push-button models all work differently. You will need the current code to start the process, a small screwdriver, and access to the lock's interior panel or reset mechanism.
The most common residential Schlage locks are keypad models mounted on doors. These use a battery-powered deadbolt with a digital keypad on the outside. To change the code, you enter your current code, press a specific button sequence, and enter the new code twice. The whole process takes less than five minutes and requires no tools.
If you own an older Schlage dial lock or a push-button model, the process is different — you may need to remove the lock from the door and access the internal mechanism with a screwdriver. This section covers the most common scenario: a modern keypad deadbolt.
Key Takeaways
- Keypad Schlage locks change codes through a button sequence on the outside of the lock — no tools needed, and the old code must be entered first.
- You must enter the new code twice to confirm it, and the lock will beep or flash to signal success.
- Dial and push-button Schlage locks require removing the lock from the door and accessing the internal reset mechanism with a screwdriver.
- If you forget the current code on a keypad lock, you will need to contact Schlage or a locksmith, as there is no override method without the old code.
- Battery-powered keypad locks need fresh batteries to change codes — if the lock is unresponsive, replace the batteries first.
How to change the code on a Schlage keypad deadbolt
Start by checking that your lock has power. Press any button on the keypad — if nothing happens, the batteries are dead. Replace them with fresh AA or AAA batteries (depending on your model) and try again. A working lock will beep or light up when you press a button.
Enter your current access code and wait for the lock to beep or flash green. This confirms the lock recognizes you. Then press the Schlage button (usually marked with the Schlage logo) and hold it for three seconds until the lock beeps twice. This puts the lock into programming mode.
Enter your new four-digit code. The lock will beep once to confirm. Enter the same code again — the lock will beep twice when the new code is accepted. Your old code is now inactive, and only the new code will open the lock. Test it by locking the door and entering the new code from outside.
Changing codes on Schlage dial locks
Dial locks — the kind with a rotating dial instead of buttons — require you to remove the lock from the door. You will need a screwdriver that fits the screws holding the lock body to the door. Remove these screws and pull the lock away from the door frame.
Once the lock is out, look for a small reset lever or pin on the back or side of the lock body. Consult your lock's manual to find its exact location, as this varies by model. Move the reset lever to the "change" position or press the reset pin, then rotate the dial to your new combination. Move the lever back to the locked position.
Reinstall the lock in the door frame, making sure it sits flush, and tighten the screws. Test the new combination before you close the door completely.
Changing codes on Schlage push-button locks
Push-button locks — older models with a row of numbered buttons you press in sequence — also require removal from the door. Remove the screws holding the lock to the frame and pull it free.
Look for a small reset button or lever on the back of the lock. Press and hold this button while you press your new code sequence on the buttons. Release the reset button, and the new code is set. Reinstall the lock and test it.
What to do if you forget the current code
If you do not know the current code on a keypad lock, you cannot change it yourself. Schlage locks do not have a master override or bypass method — the lock will not enter programming mode without the correct current code first.
Contact Schlage customer service with proof of ownership (your receipt or the lock's serial number). They may be able to help you reset the lock remotely if it is connected to their smart home system, or they will direct you to a licensed locksmith in your area. A locksmith can remove and reset the lock, but this will cost between $75 and $150 depending on your location.
Batteries and troubleshooting during code changes
If the lock does not respond while you are trying to change the code, the batteries are almost certainly dead. Replace them with fresh batteries of the correct type — check the battery compartment or your manual for the size. Some Schlage locks use AA batteries, others use AAA, and a few use 9-volt batteries.
If the lock still does not respond after new batteries, try pressing the Schlage button longer — hold it for five seconds instead of three. Some models require a longer press to enter programming mode. If the lock beeps but does not accept your new code, make sure you are pressing each digit clearly and waiting for the confirmation beep between entries.
If the lock beeps three times in a row, this usually means the code was rejected. Start over from the beginning: enter the current code, press the Schlage button, and try entering the new code again.
Smart Schlage locks and app-based code changes
If your Schlage lock is connected to the Schlage Home app or another smart home system like Apple Home or Google Home, you may be able to change the code through the app instead of at the lock itself. Open the app, find your lock in the device list, and look for a "manage codes" or "change access code" option.
App-based changes are often faster and let you set temporary codes that expire on a specific date — useful if you are renting out a room or giving temporary access to a contractor. However, the lock must be connected to your home Wi-Fi and have a strong signal for app changes to work. If the connection drops, you will need to change the code at the lock itself.
Frequently Asked Questions
Can I have multiple codes on one Schlage lock?
Most keypad Schlage locks store only one active code at a time. When you enter a new code, it replaces the old one. Some smart Schlage locks let you create multiple codes through the app, each with different access times or expiration dates, but this requires the lock to be connected to Wi-Fi and the Schlage Home app.
What happens if I enter the wrong code twice while changing it?
If you enter the new code incorrectly the second time, the lock will beep three times and reject the change. Your old code remains active. Start the process over: enter the current code, press the Schlage button, and enter the new code twice, making sure each digit is clear.
Do I need to remove the lock from the door to change the code?
No, not for keypad locks. You change the code from outside the door using the buttons on the keypad. Dial and push-button locks do require removal, because the reset mechanism is on the back or inside of the lock body.
How long does it take to change a Schlage code?
Keypad locks take about two to five minutes. Dial and push-button locks take longer because you must remove the lock from the door, reset it, and reinstall it — usually 15 to 30 minutes if you are comfortable with a screwdriver.
Can a locksmith change my code if I am locked out?
Yes. A locksmith can remove the lock, reset it to a new code, and reinstall it. This costs $75 to $150 depending on your location and the time of day. If your lock is connected to a smart home system, Schlage customer service may also be able to help you regain access remotely.
