The padlock shackle is not released when I select UNLOCK

Before attempting troubleshooting steps, please verify that you are following the Basic Requirements of Opening a Sera4 Lock. If these requirements are met, please follow these steps: 

1. Push and hold the padlock shackle down, while selecting UNLOCK in the Teleporte application 3 times. Every time you select UNLOCK, you need to wait until the option is shown again to select again.
2. Release the shackle and push it down again, the system should lock it this time.
