When to Call a Professional
Contact a locksmith if the tamper alarm continues after following all steps, if you notice signs of actual forced entry attempts, or if the lock mechanism appears damaged. Also seek professional help if door alignment issues require frame adjustments beyond simple hinge tightening.Frequently Asked Questions
What triggers a Schlage smart lock tamper alarm?
Tamper alarms trigger when the lock detects forced movement, attempted removal, impacts to the lock body, or significant vibrations that could indicate break-in attempts.
How do I stop a Schlage tamper alarm that won't turn off?
Enter your valid user code on the keypad or use the Schlage Home app to dismiss the alarm. If these don't work, remove the batteries for 10 seconds, then reinstall them to reset the lock.
Can weather cause false tamper alarms on Schlage locks?
Yes, strong winds, temperature changes causing door expansion, or heavy rain causing door swelling can trigger false tamper alarms by moving the lock or door frame.
Will a Schlage tamper alarm drain the battery faster?
Active tamper alarms consume more power due to increased sensor activity and potential alert notifications. Clear false alarms promptly to preserve battery life.
