Frequently Asked Questions

How long does the Schlage red X lockout last?
The fast flashing red X lockout lasts exactly 30 seconds. The lock will automatically reset and allow code entry attempts after this period expires.
Will the Schlage lock permanently lock me out after multiple wrong codes?
No, Schlage smart locks only have a 30-second temporary lockout. However, repeated incorrect attempts will trigger the lockout each time, so it's important to verify your access code before entering it.
Can I bypass the red X lockout on my Schlage lock?
No, the lockout cannot be bypassed - this is a security feature. You must wait the full 30 seconds. However, you can still use your physical key to unlock the door during the lockout period.
What should I do if I forgot my Schlage lock access code?
If you forgot your code, you can perform a factory reset by removing the batteries and holding the Schlage button while reinserting them. This will erase all codes, so you'll need your programming code to set up new user codes.
Why does my Schlage lock keep showing red X even with the right code?
If you're certain you're using the correct code but still getting red X errors, check for sticky keypad buttons, low battery, or keypad wear. You may need to clean the keypad or reprogram the user code.
