To change a Kwikset lock code, you generally use the Program button on the inside of the lock, enter a new 4–8 digit code on the keypad, then press the Lock button to save and test it with the door open for safety.

How To Change Kwikset Lock Code

Changing a Kwikset lock code is usually quick once you know where the Program button is on the interior assembly. The exact steps can vary slightly by model (standard keypad vs. SmartCode vs. touchscreen), but the core idea is the same: enter programming mode, type the new code, save, then test.

Step‑by‑Step Basic Method

For many Kwikset keypad and SmartCode models (910, 913, 914 and similar), the process is roughly:

  1. Prepare the lock
    • Keep the door open and unlocked so you don’t accidentally lock yourself out.
 * Remove the interior cover if needed to expose the **Program** button and batteries.
  1. Enter programming mode
    • Press the Program button once to work with the first user code slot; press it twice for the second slot, and so on (on some older models).
 * On many smart models, pressing the Program button once simply puts the lock into programming mode for adding/changing a code.
  1. Enter a new user code
    • On the exterior keypad, type your new 4–8 digit code.
 * Avoid obvious sequences like 1234 or your address number.
  1. Save the new code
    • Press the Lock button (or the keypad’s big lock icon) to save.
 * A green light and a single beep usually mean success; repeated red flashes and several beeps mean it failed, often due to a duplicate or invalid code.
  1. Test the new code
    • With the door still open, press Lock , then enter the new code to see if it unlocks.
 * If it fails, repeat the steps carefully and watch the light/beep feedback.

Changing vs. Deleting Codes

Depending on your Kwikset model, “changing” a code may mean deleting the old one, then adding a new one in its place.

  • For models like SmartCode 955 and similar:
    • You often delete the existing user code and then add a new code in that slot.
  • For SmartCode touchscreen models (e.g., 915/916/99390):
    • You may:
      • Enter programming mode.
      • Enter your current code, confirm with Lock.
      • Enter the new code, then press Lock again to save.

If your lock has a Mastercode enabled, you typically have to enter that Mastercode first before changing or adding user codes.

Model‑Specific Notes (Quick View)

Here’s a quick guide for common Kwikset families; always cross‑check with your manual or model number:

[7] [4][7] [9][4] [2][9] [3][9] [3] [8][5] [8]
Kwikset family/model Typical change‑code method Key details
Basic keypad deadbolt (older mechanical keypad) Press interior Program button 1× for code #1, 2× for code #2, enter new 4–8 digit code, press Lock. Codes stored in slots; LED/beeps confirm success or failure.
SmartCode 910/913/914 (button keypad) Open door, press Program, enter new code on keypad, press Lock to save. Program button on interior; may require Mastercode first if enabled.
SmartCode 915/916, 99390 touchscreen Door open, press Program, enter existing code + Lock, press Program again, enter new code + Lock. Touchscreen with checkmark/lock icons; feedback via screen and beeps.
SmartCode 917 & 955 Delete unwanted user code, then add the new code in its place using Program button and keypad. Supports many user codes (up to 30 on some models); often used on interior doors.

Safety, Security, and Troubleshooting

A few quick tips to keep your home secure and your Kwikset behaving:

  • Always program with the door open. This avoids getting locked out if the new code fails.
  • Use unique, hard‑to‑guess codes. Avoid birthdays, addresses, or repeating patterns like 1111.
  • If the lock keeps rejecting the new code:
    • Make sure the code is 4–8 digits and not already in use.
* Replace weak batteries; low power can cause weird programming behavior.
  • If everything is messed up:
    • Most Kwikset smart locks allow a factory reset , which wipes all user codes so you can start fresh, then set a brand‑new main code.
