# Padlock doesn't close

1. Reset the internal mechanism of the padlock depending on the configuration: 
     1. If the padlock is using standard latch mode, connect to it with the Teleporte mobile application and select UNLOCK three times in the mobile application.
     2. If the padlock is using connected latch mode, connect to it with the Teleporte mobile application and select UNLATCH three times from the main menu.
2. Push the shackle down afterwards, the padlock should re-latch this time while showing the LED in green colour.
3. If the shackle doesn't re-latch, then repeat steps 1 and 2 while connecting an external charger to the micro USB port on the side of the padlock to power it. Please see the external power guide [here](https://cx.sera4.com/ap3-external-usb-power?hsLang=en)
