• a lock device comprising an accelerometer for detecting motion of the lock device and a lock mechanism for controlling access through a door, the lock device configured to receive a credential from a mobile device, monitor a distance between the mobile device and the lock device, detect an intent action by a user of the mobile device in response to a specific vibration signature sensed by the accelerometer, and unlock the lock mechanism if the mobile device is within a predetermined distance from the lock device and the intent action is an approved intent action;
• wherein to monitor the distance between the mobile device and the lock device comprises to determine a first distance between the mobile device and the lock device within the predetermined distance and determine a second distance between the mobile device and the lock device at a time subsequent to the determination of the first distance;
• and
• wherein the lock device is configured to ignore possible intent actions by the user for a period of time subsequent to the determination of the second distance if the second distance is greater than the first distance.
