When to Call a Professional
Contact Kwikset support or a locksmith if you find evidence of actual tampering, physical damage to the lock mechanism, or if tamper alerts continue after following all troubleshooting steps. Professional assistance is also recommended if the lock fails to operate properly after a tamper alert.Frequently Asked Questions
What triggers a Kwikset BHMA tamper alert?
A tamper alert is triggered when the lock detects unusual force applied to the cylinder, repeated failed unlock attempts, or internal mechanism interference that suggests forced entry attempts.
Are Kwikset tamper alerts false alarms?
Most tamper alerts are legitimate security events, but they can occasionally be triggered by environmental factors like extreme temperature changes, low batteries, or mechanical wear affecting sensor sensitivity.
Can I disable tamper alerts on my Kwikset lock?
Tamper detection is a core security feature and cannot be completely disabled. However, you can adjust notification settings in the app to control how you're alerted to these events.
Will a tamper alert lock me out of my house?
No, tamper alerts do not prevent normal operation of the lock. You should still be able to unlock using your code, app, or physical key. If you cannot access your lock, there may be additional mechanical issues.
How long do tamper alerts stay in my Kwikset app history?
Tamper alerts and other lock events typically remain in your app history for 30-90 days, depending on your specific Kwikset lock model and app version. Check your app settings for exact retention periods.
