How to change a Schlage lock code yourself

Most Schlage locks let you change the code yourself using the lock's keypad or a mobile app, depending on the model. You do not need a locksmith or special tools — the process takes 5 to 15 minutes and involves entering a master code, then programming new user codes. The exact steps depend on whether you have a mechanical keypad lock, a smart lock with Bluetooth, or an older model that requires a physical key to reprogram.

Before you start, locate your lock's model number (usually on the back of the lock or in your paperwork) and find the instruction manual. Schlage publishes free PDFs for most models on their website. If you do not have the manual and cannot find it online, you will need the master code or a reset tool to proceed — without one, you cannot change codes on most models.

Key Takeaways

  • Mechanical keypad locks require you to enter a master code, then follow a sequence to add or delete user codes without any app or internet connection.
  • Smart locks with Bluetooth (like Schlage Encode) use the Schlage Home app to change codes remotely, and you can add temporary codes that expire on a set date.
  • You need either the existing master code or a physical reset tool to reprogram any Schlage lock; without one, you cannot change codes yourself.
  • The process differs significantly between models, so checking your manual or model number on Schlage's website before starting saves time and prevents lockouts.

Changing codes on a mechanical keypad lock

Mechanical Schlage locks (like the FE575 or BE375) use a master code to unlock the programming mode. Enter your master code on the keypad, then press the Schlage button (a small button on the lock face or inside the door frame). The lock will beep and the keypad light will flash, signaling you are in programming mode.

Once in programming mode, you can add a new user code by entering a 4- to 8-digit code of your choice, pressing the Schlage button again, then entering the same code a second time to confirm. To delete an old code, enter it and press the Schlage button three times. Exit programming mode by pressing the Schlage button once more or waiting 30 seconds without input — the lock will beep to confirm you have exited.

If you do not know the master code, check your paperwork or the lock's original packaging. If you still cannot find it, Schlage sells a reset tool (a small mechanical key) for around $15 to $30 that resets the lock to factory defaults. You will then need to reprogram all codes from scratch.

Changing codes on a Schlage smart lock via app

Schlage smart locks with Bluetooth (Encode, Encode Plus, and some Connect models) use the Schlage Home app to manage codes. Download the app on your phone, create an account, and add your lock by scanning the QR code on the lock or entering the lock's serial number. You must be within Bluetooth range (typically 30 to 50 feet) to add or change codes.

In the app, go to the lock's settings and select "Manage Codes" or "Users." You can add a new code by entering a 4- to 8-digit PIN and assigning it a name. You can also set an expiration date and time — useful if you want a code to work only for a specific guest or contractor. To delete a code, select it and choose "Remove" or "Delete."

If you forget your app password, you can reset it through the app's login screen. If you forget the master code for the lock itself, you will need to factory reset the lock (usually by holding a button for 10 to 15 seconds) and set it up again in the app from scratch. Check your manual for the exact reset procedure, as it varies by model.

Changing codes on a Schlage Connect lock with Wi-Fi

Schlage Connect locks (older Wi-Fi models) also use the Schlage Home app, but they connect through your home Wi-Fi network instead of Bluetooth. This means you can change codes from anywhere, not just when you are home. The steps are the same as Bluetooth locks: open the app, find your lock, go to "Manage Codes," and add or delete PINs.

Connect locks sometimes require a Schlage Sense Hub (a small bridge device) to work properly. If your lock is not showing up in the app, check that the hub is plugged in and connected to your Wi-Fi. Restart both the hub and your lock if codes are not updating in the app.

What to do if you are locked out or forget the master code

If you change the master code and then forget it, you cannot reprogram the lock without a factory reset. A factory reset erases all codes and returns the lock to its original state, so you will need to set up all codes again. The reset method depends on your model — some use a button hold, others use a reset tool, and smart locks reset through the app.

If you are locked out and cannot reset the lock yourself, contact a licensed locksmith. Bring proof of ownership (receipt, deed, or ID matching the address) so they can verify you live there. Locksmith fees for a Schlage lock typically range from $50 to $150, depending on your location and whether they need to replace the lock entirely.

Finding your lock's manual and model number

Your lock's model number is printed on the back of the lock (if you can see it from inside the door) or on the packaging it came in. Common Schlage residential models include FE575, BE375, BE468, Encode, and Connect. Once you have the model number, go to Schlage's support website and search for "[model number] manual" — most PDFs are free to download.

The manual will show you the exact button locations, the default master code (if there is one), and step-by-step instructions for your specific lock. If you cannot find the manual online and do not have the original paperwork, contact Schlage customer service at 1-800-847-1594 (US) or through their website. They can email you the manual or walk you through the process over the phone.

Common mistakes that cause lockouts

The most common mistake is changing the master code and then forgetting it. Before you reprogram anything, write down the new master code and store it somewhere safe — not on a sticky note on the door. If you are changing codes for a rental property or shared space, make sure all authorized people know the new codes before you lock the old ones out.

Another mistake is entering the wrong number of digits. Schlage locks require codes to be a specific length (usually 4 to 8 digits). If you enter a 3-digit code on a lock that requires 4 digits, it will not save. Check your manual for the required length before you start programming.

If you are using a smart lock app, make sure Bluetooth is turned on and you are close enough to the lock. If the app says "Lock not found" or "Connection failed," move closer to the lock and try again. Restarting the app or your phone sometimes fixes connection issues.

Frequently Asked Questions

Can I change a Schlage lock code if I do not have the master code?

No, not without a factory reset. If you do not have the master code and cannot find it in your paperwork or manual, you will need to reset the lock to factory defaults using a reset tool (if your model has one) or by holding a button for 10 to 15 seconds. After a factory reset, you can set up new codes from scratch. Check your manual for the exact reset method for your model.

How long does it take to change a Schlage lock code?

Changing a code on a mechanical keypad lock takes 2 to 5 minutes once you are in programming mode. Smart locks via app take 3 to 10 minutes, depending on how many codes you are adding or removing. The longest part is usually finding your manual or master code before you start.

Can I set a code that expires automatically?

Yes, but only on smart locks using the Schlage Home app (Encode, Encode Plus, and Connect models). When you add a new code in the app, you can set an expiration date and time. Mechanical keypad locks do not have this feature — codes remain active until you manually delete them.

What if my Schlage lock is not responding to the app?

First, check that Bluetooth is on and you are within 30 to 50 feet of the lock. Restart the Schlage Home app and your phone. If the lock still does not appear, restart the lock itself by removing the batteries for 10 seconds (if it is battery-powered) or unplugging it. If you have a Wi-Fi Connect lock, check that your hub is plugged in and connected to your network.

Do I need to tell my landlord if I change the lock code?

This depends on your lease and local law. In most places, tenants cannot change locks without permission, and doing so can be grounds for eviction. If you are a renter, contact your landlord before changing any codes. If you own your home, you can change codes freely, but make sure anyone who needs access (family, caregivers, emergency contacts) knows the new code.
