If you are not paired with the mobile app with your lock, you may adjust the time of auto-lock feature. Go to the Smart Lock Settings and you can change the auto-lock feature up to 300 seconds.
If your lock is paired with the mobile app, you will need to go into the Settings in the app for that lock and change the settings for the Auto-Lock Timer. You can adjust the amount of time before the lock auto-locks or you can disable it completely.
